Part 3. Can we still believe the Bible? A scientific perspective

In this essay I consider the question: Can we still believe the Bible? from a scientific angle. This follows the previous essays in this series where I did the same from a hermeneutical (interpretive) and an archaeological perspective respectively. I engage with the problem of scientific evidence for the existence of God as well as many other related issues.

The Bible is an ancient book. It originated millennia ago within a prescientific age. As such, the Biblical perspective obviously reflects that ancient way of thinking about the world which is very different from the scientific one which goes back a mere 300 years. Does that mean that the Bible cannot say anything to us today? Does its ancient character disqualify the Bible from being taken seriously within our scientific age? These questions introduce an even more fundamental one: How does the prescientific nature of the Bible impacts on its truth? The Bible is, after all, a book that is concerned with "truth".

There are many scholars (from the Biblical Criticism tradition) who think that the prescientific character seriously undermines the validity of the Biblical narrative. They believe that its prescientific origins automatically means that the views presented are "primitive" and not compatible with our scientific understanding of the world. Some of them try to "rescue" some aspects such as the Jesus story (clinging to the truth about the resurrection) but others reject it as an ancient book that is not relevant to our present-day concerns. As such, they see an unbridgeable gap between the Biblical perspective and the scientific one.

Many conservative Christians also think in terms of such a gap but in their case, they reject the scientific perspective as being the untrustworthy one. Their thinking is moulded by the prescientific Biblical perspective which they read in scientific terms (in accordance with their contemporary education) as giving an "objective" perspective - without any concerns for the very different world from which the Biblical text originated. Obviously, the prescientific nature of the book has to be taken into account in our understanding and interpreting it. This, however, does not have to mean (as taken by Biblical Criticism scholars) that the Biblical truth is compromised. In fact, its ancient character may even strengthen the Biblical claim to the truth when it is understood on its own terms - for example, as a book written with integrity but from an observational (instead of scientific) perspective.

One of the significant problems in this discussion is the popular understandings of science which are often not at all scientific but rather belong to a scientism view of the world. When science is taken as the "measure of all things" (to quote the American philosopher Wilfred Sellars (1912-1989)) then obviously the Bible cannot perform that function. When all things are measured in empirical terms, then obviously there cannot be any place for a world beyond our empirical reach. Many people - including scientists - adhere to such a perspective without even knowing that this is a metaphysical standpoint, not a scientific one!

This deeply engrained scientism is reflected in the main reason given by atheists for not believing in God, namely that there is no direct empirical proof of His existence. Although this is (obviously) true, this perspective reflects a very basic misunderstanding about the nature of science. Once one understands the scope and limits of science (especially insofar as its empirical reach is concerned - which has been dramatically exposed within the context of quantum physics) then one knows that science is not in competition with faith.

In this essay, I consider the question whether the prescientific nature of the Bible disqualifies this ancient book as a trustworthy source of information about the ancient world and discredits its message and claim to truth? I consider the role of observation in both the Biblical and scientific perspectives. In what sense is the Biblical perspective different from the scientific one? And what about the ancient worldview in which the Biblical authors were embedded? How does that relate to the scientific view of the world? I take a closer look at the scope and limits of science to determine whether good science is in conflict with the Biblical perspective and even whether science may, in fact, support the Biblical claim to the truth!

Science and the prescientific nature of the Bible

When we consider the Bible from a purely secular angle, it seems to be an ancient book like all such books which would never have been relevant to current debate if it was not a religious book (which takes centre stage in Judaeo-Christian religion with the Jews obviously only accepting the Tanakh which the Christians call Old Testament). This, however, reflects a preconceived dogmatic position, namely that the Biblical claim to be divinely inspired cannot in principle be true. As such, it goes against an honest and open search for the truth. The alternative is to at least consider the Biblical claim that it contains God's message to humankind.

This Biblical claim is grounded on the testimonies of people (prophets and other authors) whom believers regard as true and trustworthy. These people testified about their experience of God who revealed himself in various ways to them: through an angel, vivid dreams, his Spirit and through Jesus Christ, the son of God. Their testimony concerns a very long tradition of oracles going back to those given to Abraham, the most important forefather of Israel, as well as Moses, their most important law-giver, and many other such prophets as well as the events associated with those oracles. As such, the message of God is presented as belonging to a certain historical context which includes even miraculous events such as those preceding the exodus and many others [1]. The main claim is that all the testimonies included in the Bible are true because they were given with integrity (and are sanctioned by God who inspired the authors through his Spirit).

We read, for example, that St. Paul writes: "All Scripture is given by inspiration of God" (2 Tim. 3:16). Regarding the prophets, we read in 2 Peter 1:19-21: "no prophecy of Scripture came about by the prophet's own interpretation. For prophecy never had its origin in the will of man, but holy men spoke from God as they were carried along by the Holy Spirit". The important point is that these were "holy men" of God whose testimony is trustworthy because they would not lie (especially within the context of a holy God who abhors all lying and misleading testimony (see Rev. 21:8)).

Now, even in our day and age witness testimony forms an integral part of our justice system. When enquiring about the true nature of events the court values the "true and trustworthy" testimony of eyewitnesses very high - exactly the kind of testimony that the Bible claims to present! I discuss this aspect (i.e. using the justice system as the point of departure in evaluating Biblical truth) when I considered the Bible from an archaeological angle [2]. In any good justice system, the truth is determined by both witness testimony as well as scientific data. When the testimonies are true, they would not be in conflict with scientific data even though both need interpretation (which may lead to perceived inconsistencies which are purely due to the manner of interpretation).

All witness testimony happens within a certain context which does not belong to a pure scientific setting. The same is true for the Biblical testimony. Although the context of the Biblical authors was very different from our own and they regarded the world in very different terms than us, it is difficult to see how that undermines the truth of their testimony when we take that context into consideration when interpreting the Biblical text. All eyewitnesses have some kind of belief system which may differ radically from each other (and which may to some extent influence their thinking) but that does not in itself disqualify their testimony as long it is truthfully given. This means that we cannot discard the Biblical testimony purely because it originated within the ancient prescientific age.

Even though the Biblical testimonies include pronunciations and mention events which go beyond what natural science allows (i.e. in the case of prophecy and miracles) one cannot merely reject them out of hand as untrue - if the God whom they served really exists then He could obviously have done such things. One may, however, think that those witnesses may have been mistaken because they took purely natural things in a supernatural way. And we do, in fact, find that God is sometimes said to have used natural means to accomplish supernatural things (for example, the wind is said to have opened the path before the Israelites when they crossed the sea during the exodus). But that does not necessarily negate the miraculous aspect thereof as witnessed by the people of that time. We would, however, have to take a closer look at the way in which they engaged with the world through observation to determine if their experience has validity even today.

Science and observation

The most important insight which led to our scientific age concerns the role of the observer. Things are not always as they seem to be. Copernicus discovered that our observation of the sun going around the earth each day is in fact wrong - it is merely an illusion based on the rotation of the earth in its elliptical path around the sun. This is usually understood to mean that the geocentric view is wrong and the heliocentric one correct. Now, although this may be true on the larger scale of things, there is nothing wrong in taking both perspectives as valid as long as the context of observation is taken into consideration.

During the early part of the modern period (from the time of René Descartes (1596-1650) until the first half of the twentieth century), many scientists (and ordinary people following their lead) took the heliocentric perspective in absolute terms (i.e. thinking that the sun is the centre of the universe). This coincides with the modern view that we can achieve absolute objective positions which is immune to different perspectives. Even though it was eventually recognized that the sun is merely the center of our solar system but not of the universe, this absolutist "modernist" philosophical thinking gave birth in the early twentieth century to the neo-Kantian and Logical Empiricist (Logical Positivist) schools of philosophical thought (which subsequently became discredited especially due to the findings of quantum physics - for a detailed discussion, see [3])). The validity of various perspectives was reinforced by Einstein's theory of relativity, according to which we can always define some other valid framework relative to the one we are using. In the end, everything is relative to each other and we can never proceed beyond some kind of observational perspective. This does not undermine the accuracy of the scientific endeavour.

The problem of observation is at the same time one of knowledge. How do we know that what we observe is indeed true knowledge? This is the problem tackled by the philosopher Immanuel Kant in his famous Critique of Pure Reason (also called the first Critique; 1781, 1787). Kant followed Copernicus's lead and acknowledged that all human knowledge is always obtained from the standpoint of the observer. As such, two things are necessary for obtaining "objective" knowledge: concepts (universals) as well as empirical data (particulars) given in our senses. Furthermore, all knowledge involves a determinate judgement that the empirical data (the things that we observe) is consistent with the concepts (theoretical models) that we use. As long as we can obtain such judgments, we can assert that we have obtained "objective" knowledge. 


Of particular importance to our present discussion, is the fact that this approach was developed within the parameters of normal human experience. As such, it is generally valid - but finds its systematic application in science. In this way, Kant laid the theoretical groundwork for all mathematical science.


Although we can obtain "objective" knowledge, this knowledge is not singularly determined. One may have data within certain contexts agreeing with simple models and data in other more complex situations agreeing with more sophisticated models (Kant nowhere says anything contrasting this). In this way, we may think of Newton’s theory as describing objective reality in classical contexts and Einstein’s theories as describing objective reality in relativistic contexts (at least insofar as the measurements are concerned). This reinforces the Kantian view that all knowledge is always defined in terms of the observer and always reflects a human perspective of the world. We can never obtain a "God's eye view" on things. 


This means that the perspective of the Biblical authors cannot be discounted merely because they belong to the prescientific age. All humans share the same kind of experience - and this includes humans of all ages. Their experience involves knowledge claims exactly on par with ours - even though they did not know about science and its aim to obtain such knowledge under controlled conditions. We can therefore not discount their experience only because it dates from the prescientific age! We have to say exactly why we reject the validity of their experience - and that cannot be due to a lack of integrity (see the previous section) or observational skills.


There is, however, more to the Kantian position in the Critique of Pure Reason. This work does not only present the conditions for obtaining objective knowledge - it also shows the limits within which such knowledge can be obtained. We may be able to develop theoretical models which go far beyond experience and experiment (we use the causal connection between our senses and instruments to extend our empirical access to the world) but our empirical access is severely restricted by our human condition. All our empirically-acquired data belongs to those aspects of our world that can be so accessed - that is, those aspects of our world that are measurable by our material instruments. Those things which happen(ed) or exist beyond our temporal and spatial reach can never be so accessed. This includes things which are too complex (for example, an infinity of causally related connections) or which are by their very nature forever outside empirical reach (supersensible - such as the Big Bang or quantum states which are mathematically described in terms of a singularity or imaginary numbers (with no real component)).


One of the interesting features of Kant's philosophy is that he allowed for the possibility of the existence of a supersensible realm within our world which is beyond the empirical reach of our experience and experiments. At that time, many philosophers and scientists thought that Kant merely did this to accommodate faith. In recent years, it had been shown that the conditions for the supersensible realm are satisfied in the quantum realm! [4] Quantum objects are "supersensible" (unmeasurable) and not presentable in proper space-time while being in their pre-measurement phase. As such, they are different from those that we encounter in our experiments - quantum objects adhere to superpositions of states which "collapse" to certain reduced modes that are observable in experiment.

The only reason why scientists argue that quantum objects exist even though we cannot empirically access them is that they cause certain outcomes in our world. If they did not do this (and some don't), we would not even have known about their existence! So, the question is: how extensive is the quantum realm? How many kinds of objects are there that belong to that realm? What kind of existence is that which we do not have empirical access to?

Without trying to answer these questions, we can say the following: we as humans are severely constrained in our understanding of the world! We have no hope that we will ever gain access to this other mode of existence because of the restricted nature of our human kind of sensibility. Although we can think beyond that, and formulate various mathematical conceptions that apply to that kind of existence to the extent that we may encounter outcomes produced by such objects, we would never be able to empirically access them and understand them. We can say: A part of our world is beyond empirical reach. This is also the part where "dark" matter and "dark" energy resides.

The fact that science is so severely restricted in its empirical reach leaves no doubt that it cannot be the measure of all things! There are some scientists who believe that one-day science will be the measure of all things but this is merely a belief which is doomed to fail given the restricted nature of our empirical reach! The important point is that science can only measure those things which are given as matter in space-time. Although we can manipulate quantum objects which are not in proper space-time but which can be realized in space-time, we have absolutely no idea what lies beyond our empirical reach! So, although science can provide a good description of the measurable world it cannot confirm or deny the existence of things that exist beyond that. It has no possible way, for example, to explore the existence of God empirically.

One may argue that the scientific view of the world is still much, much better than the prescientific worldview. In fact, one may argue that the Biblical authors believed in things that are unscientific like angels, spirits, souls and so forth and that that had a major influence on their interpretation of the world. But Christians (and many others) believe in these same things today - and that does not disqualify them from giving trustworthy testimonies which accurately reflect their observation of events!

When considering the validity of the Biblical perspective, one, however, has to confront the issue regarding the existence of angels, spirits and souls. Although it is true that these things do presently lie beyond the reach of science (and their existence cannot be confirmed) that obviously does not necessarily mean that they do not exist! The scientific view of the world does not exclude the possibility of their existence - it is the scientism view which takes current (!) science as the measure of all things which does that. This means that our scientific view of the world might be more in agreement with the ancient worldview that one might suspect. Although many scholars have asserted that the ancient worldview is "primitive" and in direct conflict with the scientific one, this judgment does, in fact, says more about their dogmatic position than reality.

Science and the ancient worldview

At this point, we may take a closer look at the ancient (Biblical) worldview to see how it relates to the scientific view of the world. One of the main features of that view is the distinction between the material world of observation and the invisible world which exists beyond that. We find this distinction all over the ancient world and even in Greek philosophy where Plato (and other ancient philosophers) made that distinction.

Insofar as the invisible world is concerned, the ancients found a way to make that "visible" within their world. They took the starry heavens of the night sky as reflecting the reality associated with the invisible world. In this regard, they observed that the rotation of the starry heaven around the earth (due to the earth's rotation; in the same way that the sun goes around the earth) creates the image of a large rotating cosmic egg on which all the stars are located. The top and bottom of this "egg" are located at the northern and southern "poles" of heaven respectively, in accordance with the projection of the earth's rotational axis to those points. This is where the idea of a cosmic egg found in many ancient cultures originated.

Now, this egg had been divided into three cosmic realms since ancient times (already in ancient Sumer). The middle region, which was identified with the "earth", was associated with the region of the sky between the solstice points (on the horizon). The four "corners" (or "pillars") of the "earth" were defined by the solstice and equinox points. To the north - that is "above" the "earth" - is the region which was identified with "heaven" and to the south - that is "underneath" the "earth" - is the underworld (Hell). Both these regions belong to the otherworld. These regions are brought together by the cosmic tree (the cosmic axis) which stretches through them all. The stars were identified with the gods associated with those regions (for a detailed discussion, see [5]). As such, we often find in the Biblical tradition that the angels (which replaced the "gods" of ancient times) were identified with stars or planets (Judg. 5:20; Job 38:7; Rev. 1:20 etc.).

Some scholars have interpreted this three-tiered picture of the world as a very "primitive" one. Now, it may not be part of our modern scientific view of the world but is nonetheless a very sophisticated worldview in which the movements of the starry heavens are reflected. It is only when one takes this worldview as a true representation of the world as it really is (in scientific terms) that it would be wrong (just like the geocentric view). The ancients, however, did not take it as such but as a reflection of the invisible world which they regarded as the truly real world which lies beyond this material world. In fact, many Christians who accept the scientific worldview see no contradiction in also believing in heaven and Hell which belong to the invisible world.

Of particular interest is the fact that these cosmic regions - which are beyond sensible reach - were within the reach of the shamans and mystics. They journeyed to these regions in inner experience. They were able to do this through some kind of coincidence of their own psychology with the mentioned cosmic regions - they experienced in their inner sense that they travelled through those regions [6]. One can say that the visible representation of the invisible world in the starry heavens served as the basis for their own interaction with that world in inner experience. They believed that in the same way that humans bodily interact with the material world through their physical senses, they can interact with the invisible world with their soul through some kind of inner sense. This is the "truly real" invisible world of which the material world is merely a shadow as we find in Plato's beautiful story of the cave in his Republic.

We can now bring this ancient worldview within the framework of science. Whereas the physical world studied by science provides our scientific picture of the world, the invisible world in which the ancients believed was visualized by them as a three-tiered picture of the world. Since the three-tiered picture was never intended to be taken as an image of our material world and it merely served as an imagery device in which the otherworld was brought into focus, we need not see it in any way as being in conflict with the scientific view of the world. The primary question before us is whether such a world really exists?

Those who believe in the spirit world (as the invisible world is also called) think that humans do, in fact, have access to such a realm on a spiritual level. Those who do not believe therein, think that such kind of experiences goes no deeper than our human psychology. As such, all "near-death" and mystical experiences are explained as manifestations of our human psychology. The primary question, which science has not been able to answer, is: Is that world only in the mind or is it rather that we access that world only through the mind?

The problem is again the one of empirical access. There is no possible way that we can empirically determine whether such experiences are merely psychological or whether they involve real entities within a spirit world. Some cases have been reported in this regard where the brain's metabolism had been brought down so that it didn't require oxygen or glucose after which the patient told how she observed the operation from a disembodied position in the room and even described the particular saw used to open her skull. Those who think that this merely reflects psychological states think that the patient's visual imagery came from familiar memory and that she must have been able to see the saw when she was wheeled into the operation room (for a more detailed discussion, see [7]).

Those who believe that this kind of experience is real and that the patient observed the operation through the eyes of the soul (to use Plato's expression) cannot prove it because the soul (if it exists) is beyond empirical reach (it is non-material). Those who believe that this experience is merely psychological can also not prove that this is the case. They merely state that those things which are beyond empirical reach do not exist which is obviously not necessarily the case. Although traditional science focused primarily on the study of material things, the advent of quantum physics has shown that non-material entities outside space-time exist which suggest the possibility of other things existing beyond experimental reach (think, for example, of dark matter and dark energy). This means that we cannot in principle exclude the possible existence of the soul (and the spirit realm) from scientific discussion.

Theoretical physicists who study dark matter, have proposed that humans may have a quantum body made from this stuff [8]. Although they are fast to say that this has nothing to do with the soul, this obviously shows a remarkable correspondence with our understanding of the soul. How something like this could be brought within indirect empirical reach in an experiment has yet to be seen.

There is, however, a way to bring the scientific and ancient worldviews together in one coherent perspective. In this regard, we may remember that Plato's invisible realm had its origin with the mystics as he mentions in the Phaedo. In this, he clearly states that the soul exists in this invisible realm (which belong to the inner experience of the mystics) whereas the body belongs to the visible realm. Now, Kant's idea of the supersensible realm originated from Plato's invisible realm and he also locates the soul in that realm (within the context of his regulative metaphysics).

In Kant's regulative metaphysics - especially in his Critique of the Power of Judgment (also called the third Critique; 1790) where he presents the supersensible realm within the context of his philosophy of science - this realm is clearly delineated as being the substratum of both the material world (more correctly, systemic or mechanistic "nature") as well as our human nature (5:196, 409, 429). Kant proposed (as a regulative idea) that the supersensible realm, which is "outside" (albeit not in any physical sense) proper space/time as well as mechanistic nature, incorporates non-extended "wholes-and-parts" (outside proper space/time) which have a certain potentiality to produce material parts and aggregated wholes in nature. In his view, we need such a conception to explain the biological products of nature [4]. 

The interesting thing is - as mentioned above - that all the conditions of Kant's supersensible realm are satisfied within the quantum realm! [4] This is extremely interesting since this implies that the quantum realm may be our first point of entry to explore the invisible world of the ancients! In the same way that the invisible realm is beyond our sensible reach (and only accessible through spiritual means) the quantum realm is beyond direct empirical reach. This may mean that the invisible world of Platonic and Biblical tradition translates into the quantum world in the framework of contemporary science. Also, the idea of that a part of our human existence may consist of dark matter (and belong to the quantum realm) would be consistent with the ancient idea of the soul belonging to the invisible realm! 

At this point, we enter the realm of metaphysics. Within the modernist tradition of those who take science as the measure of all things, all metaphysics were (and are) viewed with extreme scepticism since they believed that it represents all those unscientific (and therefore, primitive) aspects of society's thinking. In their view, everything that goes beyond science should be discarded as mere metaphysics. The problem, however, is that science has since been confronted with exactly this problem: in quantum physics we have encountered a world which is beyond empirical reach and of which we can only formulate metaphysical views which are represented in the various interpretations thereof (Bohr's Copenhagen interpretation, Von Neumann's observer interpretation, Bohn's view, the many-worlds interpretation etc.). Today, philosophers of science openly speak of the metaphysics of science! We have all sorts of ideas about what that world really is like but we have no way to establish the truth thereof!

Obviously, science has reached a certain limit where it has no choice but to include metaphysics in the discussion. Although the metaphysics of science is clearly delineated, the same can be said about Kant's metaphysics - which may, in fact, be presented as a hypothesis for scientific research! Now, since the Kantian metaphysics may be taken as a rational version of the ancient metaphysical worldview, this implies that we are in effect now able to scientifically test some aspects of that ancient worldview within the parameters of Kantian metaphysics! 

Those who hold a scientism view - and take contemporary science as the measure of all things - now have the problem that science can no longer be strictly kept apart from metaphysics. They do not know whether aspects of the ancient worldview (such as the soul) may eventually be confirmed (through indirect empirical means) in the progress of science. They can try to reinforce the old view that only that which is empirically accessible is real - but no scientist worth that name would seriously consider that. 

Principles for scientific judgment

So, where do we go from here? What is to be allowed and what is to be excluded from serious scientific discussion? Again, Kant has provided us with tools in this regard. We can distinguish three areas of scientific endeavour which correspond with three kinds of scientific judgment. These vary from doing science in classical contexts to immature science (where things at the edge of science such as dark matter and dark energy are studied and theorized about). In the progress of science, things which now lie outside the possibility of experimental access may eventually come within the range of indirect empirical reach (which may eventually require considerable arguments in justifying its truth). As such, things which we may now consider as belonging merely to metaphysics may eventually enter the domain of serious science.

1. Determinate Judgment. When objects (and events) are within sensible reach, we use the classic Kantian judgment discussed above, called determinate judgment. This refers not only to classical objects but also to microscopic particles that become manifest by impacts, bubble chamber tracks and clicks on counters and which "appear" in space-time (see the work of Pringe (2007) in this regard [9]). As such, we can obtain knowledge in the classical (Kantian) sense of all objects which manifest itself as matter in space-time.

2. Regulative Judgment [10]. This kind of judgment is named after the Kantian concept of regulative ideas, which goes beyond the concepts of the understanding which apply to objects given in experience and experiment (in space/time). Regulative ideas of reason apply to objects (and events) which are beyond direct empirical confirmation but which may guide scientific research in the form of hypotheses (when they are so confirmed, we may consider them as valid theoretical models). In current science, Einstein's General Theory of Relativity, the Big Bang theory as well as quantum mechanics, are such theories. The true nature of the things described by these theories are unknowable (since they are beyond the reach of determinate judgment) and as such, they are the focus of scientific metaphysics.


Einstein's General Theory of Relativity concerns the totally of mechanistic relations (which goes beyond the limits of empirical reach in degree) and the Big Bang theory concerns something that is forever outside empirical reach (and can only be confirmed very indirectly, for example, through the observation of the redshift of light (which supports the idea of an expanding universe) and the absorption line features in the background radiation which agrees with star formation). Quantum physics is concerned with entities beyond direct empirical reach (which goes beyond the limits of empirical reach in being of a different kind of existence - otherwise they would be so accessible!) [4]. In this case, we may think in terms of the necessary conditions for something to be such or such - for example, the necessary conditions for quantum entities or quantum spontaneity (to use Bohr's expression) to exist. When these conditions are satisfied (through arguments involving mathematical and experimental aspects) we may say that we have good reason to think that these things are true.

3. Reflective Judgment. When we are not able to bring things (even indirectly) within empirical reach but think that the world may be such, then we use this kind of Kantian judgment. This judgment is merely an estimate that things are such or such and may be regarded as a hypothesis. Often mathematical theories in physics or biology serve as such hypotheses. One may think of Strings Theory, the theory that the universe includes higher dimensions and the hypotheses of dark matter and dark energy in this regard. These things are within the realm of immature science and the possibility of their existence belongs to the realm of scientific metaphysics. They belong to the larger metaphysical picture of the world. In the progress of science, things which were at one stage regarded as falling under this kind of judgment may eventually be found to become accessible in regulative judgment.

Re-considering the Bible


We can now consider the ancient (Biblical) worldview within this context. Insofar as this worldview is part of the Judaeo-Christian belief system we may regard it as belonging to religious metaphysics which is outside scientific concern. In this case, one may think that there is no necessary conflict with science (as discussed above) and decide to believe the testimony of the Biblical witnesses as a trustworthy account of historical events (or not). As discussed above, there are no good reasons why their prescientific context should disqualify their testimony - in spite of many pronunciations of certain scholars to the contrary (for a detailed discussion of the hermeneutical and archaeological views of such scholars, see [2, 11]).


As mentioned above, we are in the lucky position that Kantian metaphysics may be taken as a rational version of the Biblical worldview. As such, we may regard it as a theoretical model on par with any other similar mathematical model which presents a metaphysical picture of our world. The reason why this is of particular importance to our present discussion is that scientific progress has resulted in many aspects of the Kantian metaphysics - which originally belonged to the third kind of judgment (reflective judgment) - coming within the range of the second kind of judgment (regulative judgment). Using the scientific method of testing hypotheses, we may now evaluate the correctness of Kant's metaphysics on various fronts.

Kant's metaphysics includes the following: 1) God created the world (see the fourth antinomy, i.e. conflict of laws), 2) the material world had a beginning (see the first antinomy), 3) the material world has a supersensible (or: noumenal) substrate which is also the substrate of human nature (see the third Critique), 4) the noumenal self of humans is the soul, 5) The supersensible realm is ruled by absolute spontaneity (see the third antinomy). This is necessary for free will which is the ability to live in accordance with the moral law. In the context of biology this may be conceptualized as a potentiality that non-extended "wholes-and-parts" have to produce material parts and aggregated wholes in nature (see the third Critique) [4], 6) an unfolding process of evolution in accordance with God's design through which the potentially of non-extended "wholes-and-parts" to produce material expressions leads to adaptations which result in ever more complex organisms and life forms.

One may take points 2) - 6) as indirect evidence for the existence of the Judaeo-Christian God. These things are consistent with the view that God created all things in the beginning and that his requirement that humans keep the moral law is in line with their human abilities. Kant also presented the opposing view held by contemporary atheists within the context of his first, third, fourth and seventh antinomies which deny these things.

During the period after Kant presented his view, there developed a general consensus (in scientific and philosophical circles) that Kant was wrong and that 1) the world had no beginning, 2) the material world has no supersensible substratum, 3) spontaneity does not exist (only deterministic causes exist), 4) humans do not have a soul, 5) all evolution takes place through mechanistic means as described by Darwinistic theory.

Now, after the advent of Einstein's theories, the Big Bang theory, quantum mechanics and quantum biology, the scientific community now accepts 1) the world had a beginning, 2) the quantum realm exists (which satisfies the conditions of Kant's supersensible realm), 3) quantum indeterminism (which satisfies the Kantian conditions for spontaneity) is proven in the context of the collapse of superpositions of states to reduced states (corresponding with the Kantian regulative concept of non-extended "wholes-and parts" being realized as material parts and wholes). We also find that alternative theories of evolution have been proposed in biology which is consistent with the Kantian model (for a detailed discussion, see [12]). Now, the randomness inherent in neo-Darwinian evolution is replaced by the (quantum) laws of nature in accordance with design in the cosmos [13]. 

These are, in fact, the only things within the reach of science which may serve as indirect evidence for the existence of the Biblical God in contradistinction with other possible gods. The only other evidence is the testimonies found in Scripture. Although the existence of the soul is also important within the Judaeo-Christian worldview, it obviously does not belong exclusively to that view. It may, however, serve as supplementary evidence when taken together with the other evidence.

The remarkable thing is that Kant's metaphysics had (in spite of it originally being generally rejected!) been shown to be correct insofar as we had been able to test that in the progress of science - which serves as confirmation of the Biblical worldview! Usually, when a theoretical model is confirmed in such a spectacular way, scientists accept that it is valid. But somehow, the idea of God's existence is not allowed within the secular approach of scientism (it is banned in principle). What is also remarkable, is that those who take science as the measure of all things have been shown to be wrong in every possible way (on all the mentioned points)! Nonetheless, the general secular opinion is still that they are right!! This is truly mind-blowing.

If we take the Kantian model in its totality, then only the existence of God and the soul is still outside current scientific debate. Now, although God is forever beyond empirical reach, the soul may eventually come within reach as discussed above. One may argue that the confirmation of things predicted by Kant's metaphysical model (consistent with the scientific method!) serve as substantial evidence for the existence of God in the very same way that the confirmation of things predicted by the Big Bang Theory serves to confirm that event which is also absolutely outside experimental reach (in the same way as God; for a detailed discussion, see [14])). Why would one accept the one but not the other if not through a massive bias against the Biblical position?

The only outstanding aspect of Kant's model which may eventually come within scientific reach is the human soul. Above, we saw that it may actually already be within the parameters of scientific mathematical theorizing albeit not under that name (within the context of theoretical models of dark matter). It is easy to show that both the soul as well as noumenal intuition (which Christians take as deep impressions of God's voice) are consistent with the scientific worldview (see [15]). I predict that the existence of the soul will also eventually be confirmed (albeit very indirectly).

Conclusion

When we consider the trustworthiness of the Bible from a scientific standpoint, we find that the idea that it cannot be trusted because it comes from a prescientific age is very wrong. This is just not the case. There is absolutely no reason why we cannot trust the witness testimonies of the Bible even though large parts of society have been conditioned not to believe it. I think the evidence speaks for itself - but for those from the modernist (atheistic) circle, nothing would serve as sufficient evidence. They would always lift the bar - demanding the kind of evidence which is forever outside our human reach, not because God does not exist but because of the limitations of our human condition.

It is exactly because of this radically restricted human condition that one can understand why the Bible asserts that it is through God's revelation in Scripture that he had chosen to communicate with humankind. In the end, we as humans can never proceed beyond "knowing in part". Our hope does not lie in the full understanding of all things that science aspires to (which can never happen) but in faith built upon the integrity and trustworthy witness of those people who wrote the Bible. The Biblical perspective is not in conflict with science. Rather, it goes far beyond the reach of science. As such, science can never be the measure of all things. Biblical truth can, however, be that measure.

[1] Biblical Criticism scholars believe that the Biblical testimony dates long after the events and can as such not be trusted. But that merely reflect their own ideological perspective. The Bible mentions in various places that the authors were indeed eyewitness, for example, the prophets who wrote the monarchical histories of Israel or St. Luke's (Luk. 1:2,3) mentioning his using such eyewitnesses. Various court prophets are mentioned in Hebrew tradition as the ones who wrote down the oracles as well as the story which tells the context in which that happened. Among these were Samuel (I Sam. 10:25), Nathan (1 Chr. 29:29; 2 Chr. 9:29); Gad (1 Chr. 29:29; 2 Chr. 29:25), Ahijah (2 Chr. 9:29), Shemaiah (2 Chr. 12:15), Iddo (2 Chr. 12:15; 13:22), Elijah (2 Chr. 21:12), Isaiah (2 Chr. 32:32) and others. The author of the Chronicles of the Hebrew kings mentions the histories written by Samuel (from the time of King Saul), Nathan and Gad (from the time of King David), Ahijah (from the time of King Solomon), Shemaiah and Iddo (from the time of King Rehoboam), Elijah (from the time of King Ahab) and Isaiah (from the time of King Hezekiah). Regarding the older stories, I discuss that elsewhere [16].

The Biblical authors can obviously not be called for cross-examination as we find in our justice system but that does not mean that we cannot use the justice system as the model for evaluating the Biblical story. We can use a process similar to the justice system to make judgments about historical narratives such as those found in the Bible.

Science and the spiritual realm

The spiritual realm is the most basic ingredient found in about all religion. It has often been forcefully renounced in scientific circles. Atheists take it for granted that it does not exist. In this essay, I show how that realm has been conceptualized in Immanuel Kant's philosophy. I also argue that its existence has been confirmed in science in the context of the quantum realm!

The idea that a spiritual realm exists alongside our material world is extremely old. All the peoples of the ancient world believed in it. They believed that although this realm is inaccessible to our senses, it nonetheless exists and we have access to it through our human soul/spirit. Apart from human spirits, there are also other kinds of spirits and gods who belong to that realm. The spiritual realm is also part and parcel of the Judaeo-Christian worldview. In their view, God's Spirit is operative in the spiritual realm. They also believe that this realm makes life after death possible and that heaven and hell exist in this realm.

With the onset of the scientific age, the validity of these ideas was increasingly questioned. Although science is clearly restricted in its reach and is only able to study those things which are empirically accessible, some took that to mean that only that which is in fact so accessible should be reasonably accepted into our metaphysical view of the world. Enlightenment atheists and agnostics believed that the ancient belief about a realm outside our sensible and experimental reach is just a pie in the sky. In their view, such religious views have no scientific grounding and should be discarded since they belong to the pre-scientific age when people held primitive ideas, many of which have been refuted by science. In their view, we cannot believe things that cannot be proven. And since this realm lies beyond the reach of our experiments, they rejected it.

Even today, when we consider the spiritual realm in the context of the scientific conversation, some would immediately take offence. They feel that it is totally unacceptable to even seriously consider something like that. Now, I agree that we cannot at this point in our scientific progress say anything about the existence of spiritual entities. On the other hand, the possible existence of such a supersensible realm that exists alongside our material realm is in fact nowadays within the reach of serious science! We can consider its possible existence in the light of contemporary science. I argue in this essay that its existence is confirmed in quantum physics.

When we want to discuss such a realm in the context of serious science, we must, first of all, say what such a realm would entail. We need a rational-theoretical model that we can subject to rigorous scientific testing. Luckily we have such a model: The philosopher Immanuel Kant developed such a metaphysical model in which he incorporated exactly such a supersensible realm!! Kant gave very particular specifics on what such a realm would be like if it exists. In this essay, I use this Kantian model when I engage with the question of whether that realm has been confirmed in science.

Philosophy and the spiritual realm

The intellectual consideration of the spiritual realm started with the well-known philosopher Plato (5th to 4th century BC). Plato reworked the idea of the spiritual realm as it was taught by the Orphics, an early group of mystics, into his own idea of an intelligible realm. As such he conceptualized this realm as an invisible realm which, although inaccessible to our senses, may be accessed through our intellectual intuition. In his Phaedo, Plato states quite openly that his idea is based on the spiritual realm of the Orphics and he even argues that the soul exists in that realm. As such two worlds may be distinguished: A visible world in which the human body exists and an invisible realm in which the soul exists.

In Plato's view, the invisible realm is "the realm of the absolute, constant and invariable" whereas the visible world is always changing. He got this idea from Parmenides of Elea (born ca. 515 BC) who also argued for two such worlds, namely one that is the "real" world which is eternal, indivisible, motionless and changeless and the other which is the world of our senses, which is a world of "appearances". In Plato's view, the invisible "forms" of material things belong to the first realm, whereas the visible things of the material world belong to the second realm. Insofar as the soul is concerned, he writes in the Phaedo: "Since the soul is invisible, it belongs to the eternal invisible world... When it [the soul] investigates by itself, it passes into the realm of the pure and everlasting and changeless; and being of a kindred nature, when it is once independent and free from interference, consorts with it".

Plato's opinion about the relation between these worlds changed through the course of his writing. At first (in the Phaedo) the "invisible world" is viewed as a separate domain where human souls go between lives (and where the gods live), but in the Republic, the "intelligible" world (as it is now called) is more closely connected to our own world. This (our) world is somehow dependent on the "real" world for its existence (where the forms for the phenomena in this world are situated). In the Timaeus, the real world (of unchanging being where the forms are situated) underlies this world (of becoming) in a very real sense in that it gives form to it.

Plato's idea of the intelligible and phenomenal realms was reworked by later philosophers like Immanuel Kant (1724-1804). In this essay, I am only concerned with Kant's so-called "critical period" when he wrote his great philosophical works. Kant accepted the Platonic distinction between the "noumenal" world, as he calls Plato's intelligible world (from the Greek word for understanding, "nous"), and the phenomenal world. In Kant's view, the noumenal realm is the substrate of the phenomenal world [1] and all phenomena have originally appeared from that substrate. Kant also accepts the human soul, which in his thinking is just the "noumenal" part of humans, i.e. that part which belongs to the noumenal realm.

In Kant's metaphysics as he presented it in his philosophy of science in the Critique of the Power of Judgment, the noumenal realm, which is also called the "supersensible realm", has five basic characteristics, namely 1) it is supersensible, that is, beyond human experiential and experimental reach, 2) it is outside proper space/time 3) it is outside "nature", which refers not to empirical nature but the concept of nature as a system which is ruled by mechanism, that is, deterministic causality 4) it is governed by absolute spontaneity and the entities in this realm, the non-extended wholes-and-parts (my terminology) has the spontaneous potentiality to produce material parts and aggregated wholes in nature 5) it produces phenomena in nature which simply "appear" in contrast with the appearances of everyday objects of the senses (for a detailed discussion, see [2]).

Since Kant's time, there had been general agreement in philosophical circles that such a realm does not exist and that Kant has merely brought it into his philosophy to accommodate the Judaeo-Christian worldview, especially the soul and life after death. The problem that they had with this realm is that it is forever beyond empirical reach. Science can therefore never engage with it.

The supersensible realm and science

There is, however, one important possibility regarding the supersensible realm that Kant did not foresee which may allow partial empirical access of that realm (allowing for the possibility of manipulating entities in such a realm). This concerns his conception of space and time. Kant took space and time as pure intuitions through which we as humans engage with the material world. He also allows for various possible conceptions of space which may (through reason) be ascribed to those things that are beyond perception, which includes "noumena" (the entities that belong to the noumenal realm). Kant calls this "ideal space". What Kant did not foresee is that time may be coupled, not with proper space (as we normally do in perceiving the material world), but with ideal space which describes noumena.

If this last possibility is allowed, then we might be able to bring the noumenal realm under scientific scrutiny. And this is exactly what happened. In quantum mechanics, space and time are decoupled and time is coupled with abstract Hilbert space which is associated with quantum entities. We know today that the quantum realm adheres to all the Kantian characteristics of the noumenal realm as I will now show.

1. Supersensible. Quantum entities in their pre-measurement state have irreducibly complex amplitudes (i.e. in terms of complex numbers) and as such, they can never be brought into the range of human perception which is restricted to material things governed by real numbers (these complex numbers do not even have a real component). It is only when we measure these entities that they become situated in proper space-time.

2. Outside proper space-time. The kind of space that is used to mathematically describe these quantum entities (called Hilbert space) is also described in complex numbers! Although there have been efforts to reformulate such equations in proper space, these have not been successful (their complex nature is merely made implicit). The entities that we study in quantum mechanics are therefore not in proper space until we measure them. In Quantum Field Theory, the quantum entities are even outside space-time before measurement [3]. This is exactly what Kant has postulated for the supersensible realm.

3. Outside "nature". The quantum mode of existence (as I call it) which involves superpositions of states is also outside "nature". The interactions between quantum entities go beyond the proper space-time framework as can be seen in the EPR (Einstein, Podolsky & Rosen) experiments (this name originated from their famous paper). Such connections are not restricted to the deterministic rules governing objects in space-time. In fact, Redhead [4] has shown that the so-called Bell proof (which led to the EPR experiments) implies that all kinds of determinism have broken down in these interactions between the quantum entities.

4. Spontaneity. We also know that the quantum mode of existence is governed by another rule than determinism, namely indeterminism (which may be taken as spontaneity). Niels Bohr used the empirical evidence of spontaneity to formulate his well-known quantum postulate. As such we can say that quantum outcomes are spontaneously produced. One of the clearest examples of such spontaneity is atomic decay which happens absolutely spontaneously without any external intervention. 

5. Phenomena that "appear". The phenomena that are so produced - which include those microscopic particles that are observed during impacts, in bubble chambers etc. - are different from the everyday phenomena in that they "appear" from the quantum substrate.

It is clear that all five relevant characteristics of Kant's supersensible realm have been confirmed in quantum physics. This means that science has confirmed the existence of a supersensible realm exactly in the form that Kant postulated it in his metaphysics! The quantum realm is, in fact, Kant's supersensible realm. Although the existence of the soul has not yet come into the range of scientific research, there is no reason why that would not eventually happen [5]. The fact is, however, that this very realm that modernist philosophers and scientists rejected as a pie in the sky, has now been (indirectly) confirmed empirically.

This brings me to a remarkable observation: all the ancients believed in a supersensible realm which was forcefully rejected by modernist science and especially by atheists since it did not conform to their worldview. The ancients were right; the modernist scientists, philosophers and atheists were wrong! The very spiritual realm that Kant conceptualized as the noumenal realm in his philosophy - which in philosophical discussion originated with the view of the mystics in Plato's time - has now been confirmed by science. 

Conclusion

We live in remarkable times! The science of modernist times is dead - and the metaphysical views that were grounded on that science are dead too. Although those who reject the possibility of a spiritual realm do so mainly because they reject the idea of gods (spirits) and especially God, it seems that scientific discovery is not on their side. Scientific research and discovery about what our world is like are consistent with a supersensible - or spiritual - realm.

I freely admit that this essay is restricted in scope and that the issues require more detailed discussion. I have already done this elsewhere [2]. Although atheists could try to argue that the view presented here is merely one alternative to other possible readings of quantum physics, I can say in defence that the basic things that I argue for regarding the supersensible realm (the five characteristics) are indeed widely accepted in scientific and philosophical circles. I argue that science has in fact confirmed Kant's conceptual system which was originally based on the idea of the spiritual realm. I conclude: the spiritual realm (in its most basic formulation) has been confirmed by science.

[1] Interpreters usually think that Kant's idea of the noumenal realm in his first great work, the Critique of Pure Reason, is substantially different from that in the two other Critiques, namely the Critique of Practical Reason and the Critique of the Power of Judgment. I reject that. In my view, Kant held similar views (which did develop over time) throughout his critical period, i.e. in all three Critiques.

Science and our restricted human understanding

Science is often presented as having the potential to unlock and understand all the mysteries of our world. There is, however, one severe problem that is not taken into account in this regard: due to our human constitution, we have restricted access to the world. As humans, we would never be able to fully encompass the world for the simple reason that both our sensibility and understanding are severely limited in its reach! This is where science meets quantum objects and dark matter. This is also where science meets religion!





Humans often have a very high regard for their own abilities. This is especially common among scientists and those who follow their lead - they often think that there is no end to the possibilities of human exploration. This perspective goes back to modernist times, when man thought of himself as a god in his own right; when man thought that there is nothing which he will not eventually subdue and understand. The problem with this view, however, is that humans just do not have the capabilities to explore and access all of that which exist. Some things in our world are forever beyond our empirical reach!

In this essay, I discuss the extent of the limitations of our human access to the world around us. I show in what sense science is forever restricted in its empirical access and understanding of our world. I use the philosophy of the well-known philosopher Immanuel Kant to explore these issues. Kant engaged with them long ago and his approach is now more relevant than ever. Especially now that science has discovered that large parts of our world are "dark" to us.

The possibility of objective knowledge

Most people do not really think about their own or our scientific access to the world; they merely accept that we have full access to the world as it exists. The problem, however, is that we always access the world through our human senses or by extension, through our instruments (we use the causal connection between our senses and instruments to extend our empirical access of the world). Once we gain empirical access in this manner, the acquired data always belongs only to those aspects of our world that can be so accessed. All empirical data belongs to those aspects of our world that are measurable by our material instruments. All things that happen(ed) or exist beyond our temporal and spatial reach can never be so accessed. This includes things which are too complex (for example, an infinity of causally related connections) or which are by their very nature forever outside empirical reach (although there might in some cases be indirect ways to establish that they do in fact exist).

What about our conceptual understanding of the world? Surely we can think about the world as it really exits? Although we might think that we can in principle understand all things, our understanding is actually also very constrained. Somehow our understanding is restricted by our senses. As long as we can present things empirically in space and time, that is, when we can visualize them in some manner, we can also figure out how they work. Our understanding works hand in hand with our human senses (even when these are extended in experiment) - things that can be empirically given in our senses or in experiment can be understood. Things that lay beyond that can be conceptualized, we can think them, we can reason about them, but before we do not have empirical access to them we cannot really understand them. This means that we are also very restricted in our understanding of the world.

Kant was very interested in these problems since they are closely related to the question of human knowledge. How is objective human knowledge possible? Since we always access the world subjectively as humans, how can we obtain objective knowledge that is universally true? The possibility of empirical data, which is always given through human sensibility, is severely restricted by our human senses - not in the sense of the crudeness of our senses which can be extended far beyond that in experiments but in its limited access of the world. Since we do not access the world as it really is (but merely as it is presented in our senses or experiments), all data given in our senses or experiment is contingent - as mere sense data, we have no guarantee that this is what the world truly is like.

Even if we think that we find some order among this data, how do we know that they constitute "laws" of the world as it really is? They may be "laws" that regulate our interaction with the world at the empirical level but how do we know that they actually describe some real truths about the world? Since we do not have unconditional access to the world due to the fact that our understanding of the world is restricted by our senses, we can obviously not know anything about the world except to the extent that it is presented in our senses (or experiments). As such all "laws" that we ascribe to nature are just human conceptions applied to nature - they are forever and always "human" concepts. They are therefore always subjective (they do not objectively apply to the world as it really is).

Kant had a remarkable insight in this regard, namely that we can conceptualize things as they may be given in our senses in space and time before they are actually given as such (Kant calls this synthetic a priori, where "synthetic" refers to "pure" human sensibility, i.e. without any real data given in the senses, and a priori means that it is prior to actual experience). In this way, humans have the possibility of real experience even before actually engaging with things. When things are given empirically in our senses (which would be a posteriori) this is actually nothing but a particularization of those general things that may be given in "pure" sensibility (intuition).

The essence of Kant's idea is that our concepts of understanding work hand in hand with our sensibility (senses). Kant says that our concepts are "synthesized" with our forms of sensibility. Although our understanding is restricted by our senses, as long as it does not try to move beyond the senses (experiments), it can indeed understand things as they are given in the senses. For those things that may be given in our senses (instruments), we can formulate general rules which apply to all such things that may be given in experience or experiment. In this way science becomes possible: we can formulate general scientific laws that apply to the things that we encounter every day around us or in controlled experiments. 

In the final instance, we make judgments whether the things given empirically in the senses agree with our synthetic conceptualization of them (in pure sensibility). If they agree, then we may say that these things are indeed the things that we have formed concepts about, i.e. we can establish an "objective" truth judgment. The general rules of the understanding are applied to the particulars (empirical data) given in our senses or experiment. In this way, we can obtain objective knowledge of things even though we do not have access to the world as it really is.

The order of the world that is given in experience and experiment is understood in terms of the order (laws) that we bring to that data (through our conceptualization thereof). In the progress of experience, we can proceed to engage on an ever more substantial level with the material world of matter. The empirical data so obtained is then brought under ever more sophisticated conceptual structures (theories) - if the data (particulars) is in agreement with the conceptual structures, we can say that we have obtained objective knowledge (on an ever more substantial level). But all knowledge is always restricted to our empirical observation of nature.

The limits of our understanding

When we think about the world beyond the objects as they are given in human sensibility, we have no choice but to take our world as if it is systematically ordered - even though this can never be proven. In this context, we can think what such an ordered world might look like. In Kant's thinking, there are two ways in which the world might be beyond the reach of our senses and therefore also our understanding. In the context of our human senses, the one way relates to limits of degree, i.e. that our senses or instruments are such that they are limited in the manner in which data can be given in them (limitations in time, space and magnitude). The world as it really is may have (for us) an inaccessible extension with an infinity of relations and connections which can never be empirically brought within the range of our senses (or experiments). As such some objects and their totality of interactions are beyond our sensible (experimental) access.

The other way in which the world might be beyond our sense relates to limits in kind, i.e. that our particular kind of sensibility is such that it may not be able to access certain kinds of objects which may only be accessible to another kind of intuition than our sensible one. As such there may be objects in our world that can never be given in space and time in our senses (or instruments). In fact, we know today from our scientific research that such things exist.

To account for these two ways in which the world may be beyond our senses, Kant allowed that our phenomenal world (called "empirical nature"), that is the world of our experience and experiments, be complemented with two other concepts of the world, namely "conceptual nature" (the concept of nature taken as a total system; in short: "nature") and a supersensible realm outside nature. Nature refers to our world in its totality of deterministic connections (called "mechanism") as we can only conceptualize it, i.e. as it may really be but outside the possibility of our sensible reach.

All the objects of our experience are also objects of nature; they belong to nature and as such we can empirically access them in space and time (in the context of deterministic causality). Objects of nature, however, as they "really" are when their enormous magnitudes or infinite relations are concerned cannot be brought within the limitations of our experiments. Some scientific laws relate to nature, for example, the theories of relativity and those describing stochastic behaviour. We accept these laws but they present a systematic unity that goes well beyond the phenomenal laws that we encounter in experiment. We can think these laws; we cannot bring all of nature to which they apply within the reach of our experiments.

Kant also allowed for a supersensible realm outside nature. The difference between nature and the supersensible realm outside nature is that the all objects in nature are deterministically (mechanistically) connected; objects in the supersensible realm are not so connected (I previously showed that absolute spontaneity (freedom) rules in this realm [1]). They are also outside the framework of the space-time conceptions that apply to nature. As such we can say that they belong to a different mode of existence than the one that we conceptualize as nature. Since such supersensible objects can never be brought into our experiments, they are not empirically accessible. They stand forever outside our empirical reach. We encounter such objects in the context of quantum physics. Quantum objects in the pre-measurement stage are different from those that we encounter in our experiments - quantum objects adhere to superpositions of states which "collapse" to certain reduced modes that are observable in experiment.



The only reason why we can argue that quantum objects exist even though we cannot empirically access them is that they cause certain outcomes in our world. If they did not do this (and some don't), we would not even have known about their existence. So, the question is: how extensive is the quantum realm? How many kinds of objects are there that belong to that realm? What kind of existence is that which we do not have empirical access to?

Even if we do not try to answer these questions we have to admit the following: we are severely constrained in our understanding of the world! We have no hope that we will ever gain access to this mode of existence because of the restricted nature of our kind of sensibility. Although we can think beyond that, and formulate various mathematical conceptions that apply to that kind of existence to the extent that we may encounter outcomes produced by such objects, we would never be able to empirically access them and understand them. We can say: A part of our world is beyond empirical reach. This is also the part where "dark" matter and "dark" energy resides.

Once we are confronted with the limits of our understanding, we are forced to acknowledge that the world involves more than we had ever thought possible. This does not mean that all sorts of crazy ideas about the world should now be allowed in serious debate. It does mean, however, that our conceptualization and metaphysical constructs of the world should accommodate this aspect of our world in a sensible manner. All metaphysical conceptualizations which are still stuck in the old paradigm where only the mechanistic world is allowed, are not relevant to current debate. They do not realistically capture the world of our experience and experiments [1].

Metaphysics


We can even say that in physics we have now moved from the pure empirical study of nature (which is obviously not "pure" since we always bring empirical data under concepts) to metaphysical interpretations which can never be shown to be true or not (in the Kantian sense). As such there are, for example, various possible ways to interpret the world through the lens of quantum physics. We just do not know - and can never know - what the quantum world really is like. We can form metaphysical constructs based on mathematical theories and the available data but we can never gain knowledge of that world to the extent that it is beyond our experimental reach. At most, we can present good reasons why we think that the world is such or such.

In some sense physics has therefore entered the domain of metaphysics which was in the modern age looked down upon as not truly "scientific". In this world of metaphysics, we also find the various ways in which we can think that the world really is in accordance with our religious conceptions. The fact that we are so restricted in our empirical access of the world shows why one would never be able to prove or disprove the existence of God (As Kant has shown, all the proofs for God's existence moves from conceptual constructs to assume existence). We can merely present metaphysical constructs that capture our religious understanding of the world in a rational manner. That is, we can present good reasons why we think that the world is such or such - using a wider spectrum of data and arguments than in the metaphysics of any particular branch of science (i.e. from all aspects of our life experience). I plan to argue in another essay that Kant's metaphysics is not only a reworking of the Christian worldview but is also one of the best ways to understand the world of science.

So, due to our restricted human senses and understanding, it has now so happened that both science and religion are engaged in the very same metaphysical game with the difference that serious science keeps away from the more substantial questions regarding our human existence (That would be to move too far beyond the basic data available in experiments). All of us are nonetheless interested in those questions. As such the idea that "religion" is concerned with things which cannot be proven and is therefore not to be taken seriously is just not right; even science is concerned with things which lie beyond empirical access. Anybody who is open-minded should in this context, at the very least, seriously and carefully consider the metaphysics of religion.

Conclusion

In this essay, I focus on the limits of our human understanding. Gone are the days when scientists could think that it is just a matter of time before everything is understood. Although some - even prominent scientists - may still keep that hope alive, the reality is that philosophers of science are long past that way of thinking. Our world is just too complex - there are parts of our world that are beyond the reach of our sensible intuition (our five senses) and would require a totally different kind of intuition than the one that we use in our experimental exploration of the world.

Although some aspects of our world are empirically inaccessible, this does not mean that we cannot think about that. We can, from the context of our broader human experience, which involve human consciousness and other aspects of our existence, construct a systematic metaphysics which accommodate all our life experience. Kant presented such a metaphysics - and I hope to explore it in more detail in future. Suddenly things that modern man thought impossible, like the existence of Kant's supersensible realm, has again become part of our thinking - even scientific thinking - about the world, where it is now taken as applying to the quantum realm [1].

The question is: What about the other things that Kant also argued for in that context, for example, the existence of the human soul? Since he was right in allowing for a supersensible realm which was rejected by about all philosophers and scientists until quite recently, he might be right in other regards too. We should be humble and open to considering such possibilities. Our restricted sensibility and understanding force us to accept that we may have good reasons to believe things even though we know that we can never bring them within experimental reach to understand them. The existence of the soul might be something like this. Another may be the belief in God [2].

[2] I plan to discuss these things later in this series about Kant and quantum physics.
