The belief that science proceeds from observation to theory is still so widely and so firmly held that my denial of it is often met with incredulity. I have even been suspected of being insincere – of denying what nobody in his senses can doubt. . . . But in fact the belief that we can start with pure observations alone, without anything in the nature of a theory, is absurd.
Conjecture and Refutations, p. 46.
Ok. So if we don't proceed from observation to theory then how do we proceed? In the very context quoted above, Popper claims we need a "critical attitude" to proceed:
A critical attitude needs for its raw material, as it were, theories or beliefs which are held more or less dogmatically. Thus, science must start with myths, and with the criticism of myths; neither with the collection of observations, nor with the invention of experiments, but with the critical discussion of myths, and of magical techniques and practices.
Ibid. p. 50.
All science is cosmology . . . the early Presocratics . . . find bold and fascinating ideas, some of which are strange, even staggering anticipations of modern [scientific] results . . ..
Ibid. p. 136-137.
Popper then notes how ancient philosophers used the dogmatic beliefs of the religions of their time as the medium through which they could either support, or criticize, the belief, as either sound (through observation, logic, and experimentation), or flawed based on the same critical criteria. It's this willingness to subject dogmatic beliefs (and religion provides the most seminal example of dogmatic beliefs), to the scalpel of the scientific-method of critical examination that creates the thought processes that are manifest in modern science.
Popper's most important contribution to science is in his pointing out the fallacy of induction (or inductive logic), which is precisely the belief that knowledge proceeds from observation to theorization. And if that's not the case (and Popper is clear that it's not), then there must be some pre-theoretical belief, intuition, or dogmatic teaching, which, precedes the critical examination arising from theorizing.
Voila! Religious teachings come packaged as dogmatic truths send down from heaven to the true believer and not the doubter who would need to theorize about whether they are true or not. Religious teaching comes from dreams, sub, or pre, conscious intuitions, and deductions, which, to really experience full manifestation, must (the dreams and intuitions must) be subjected to critical analysis, argumentation, experimentation.
We know that Popper's personal friend, the great Albert Einstein, like Newton before him, proclaimed that his greatest insights came to him in the middle of the night, in a half conscious sleep-state. And they came not as observations, or fully formed ideas, but as intuitions, and deductions, quasi-religious revelation, which on waking, he subjected to the scalpel of the scientific-method, often coming to see that some of these pre-conscious deductions, intuitions, revelations, were the closest thing to truth he ever experienced.
Men have called me mad; but the question is not yet settled, whether madness is or is not the loftiest of intelligence---whether much that is glorious---whether all that is profound---does not spring from disease of thought---from moods of mind exalted at the expense of the general intellect. They who dream by day are cognizant of many things which escape those who dream only by night. In their gray visions they obtain glimpses of eternity, and thrill, in waking, to find that they have been upon the verge of the great secret.
Edgar Allan Poe (1848/1975, p. 649).
And more to our point:
Intelligence makes clear to us the interrelation of means and ends. But mere thinking cannot give us a sense of the ultimate and fundamental ends. To make clear these fundamental ends and valuations, and to set them fast in the emotional life of the individual, seems to me precisely the most important function which religion has to perform in the social life of man. And if one asks whence derives this authority of such fundamental ends, since they cannot be stated and justified merely by reason, one can only answer: they exist in a healthy society as powerful traditions, which act upon the conduct and aspirations and judgments of the individuals; they are, that is, as something living, without its being necessary to find justification for the existence. They come into being not through demonstration but through revelation, through the medium of powerful personalities. One must not attempt to justify them, but rather to sense their nature simply and clearly. The highest principals of our aspirations and judgments are given to us in the Jewish-Christian religious tradition.
Albert Einstein, Out of my Later Years, p. 22, 23.
Justifying Einstein's statement Popper himself says:
The picture of science of which I have so far only hinted may be sketched as follows. There is a reality behind the world as it appears to us, possibly a many-layered reality, of which the appearances are the outermost layers. What the great scientist does is boldly to guess, daringly to conjecture, what these inner realities are like. This is akin to myth making.
Popper Selections, p. 122.
Popper goes on to compare the scientist's bold, unanticipated conjectures, with the oldest form of science, the myth-development and criticism associated with the ancients. He notes that heliocentrism comes from the ancient religious intuition that the sun is the central manifestation of the highest god (the light-giver), who, as the highest god, must be central to all other constellations.
In pre-scientific, religious, myth, the minds of the priests intuited that the light-giver is central, and superior, such that in this pre-scientific intuition, the sun, as the light and life giver on earth, should, technically, logically, be central, and thus something like the axis upon which all other constellations revolve. As Thomas Kuhn points out, in his book,
The Copernican Revolution, Copernicus' own studies came from the Bible, and the heliocentrism of the ancient religions. Just as Popper claims, Copernicus critical attitude used heliocentrism, and concepts in the Bible, as the source for his critical belief, and argumentation, concerning the central place of the sun in the constellation of planets.
Popper's fundamental argument against the belief that science starts with theories, or knowledge based on observation, and his belief that it actually arises through deductive revelations, dogmatic intuitions, pre-conscious insights, leads him to discuss the Catholic Bishop Berkeley who used the Catholic understanding of God, and direct statements from Jesus of Nazareth, to propose that the world of observations and experience is not the axis of reality, but a constellation revolving around the true axis, the observer.
Another of Popper's scientific friends, the physicist John Wheeler, asked, what does quantum physics tell us that Bishop Berkeley hadn't already surmised from his interpretation of scripture? Wheeler says that Berkeley was perfectly correct; that reality requires the observer, and that there is no world out there without observation.
Popper concurs and acknowledges that Berkeley, writing a profound religious treatise, seems to have intuited the very basics of modern quantum physics, and, worse, for the agnostic worldview, Popper says that quantum physics literally arose partly and seminally as a scientific attempt to refute argumentation from Berkeley that had stuck in the craw of agnostic thinkers ever since Berkeley's treatise came to some semblance of fame and fortuitous transmission.
In point of fact, Popper and his philosopher friend Bryan Magee paralleled Berkeley with Kant implying that Kant, like Berkeley, turned his religious intuitions and beliefs into the very philosophy that no less than Albert Einstein said were one of the important foundations of modern scientific thought, with emphasis on quantum physics.
In his book,
Quantum Theory and the Schism in Physics, Popper says, “
We owe to Kant the first great attempt to combine a realistic interpretation of natural science with the insight that our scientific theories are not simply the result of a description of nature----of `reading the book of nature' without `prejudice'----but that they are, rather, the products of the human mind: `Our intellect does not draw its laws from nature, but it imposes its laws upon nature' (p. 3).
One thing that has always struck me forcefully about this doctrine of Kant’s is that it legitimates important components of a belief which he had held since long before he began to philosophize, namely Christian belief . . .what he did unmistakably (and un-remarked on to an extent that has never ceased to astonish me), is produce rational justifications for many aspects of the religious beliefs in which he grew up.
Let me put it this way. We know for a fact that long before Kant started to philosophize he was dedicated, simply as a Christian, to the belief that the empirical world of time and space and material objects, within which everything is evanescent and everything perishes, is something that exists only for us mortals in our present life; that "outside" this world there is another, so to say infinitely more "important', realm of existence which is timeless and spaceless, and in which the beings are not material objects.
Now it is as if he then said to himself: "How can these things be so? What can be the nature of time and space and material objects if they obtain only in the world of human beings? Could it be, given that they characterize only the world of experience and nothing else, that they are characteristics, or preconditions, of experience, and nothing else?" In other words, Kant's philosophy is a fully worked out analysis of what needs to be the case for what he believed already to be true.
