Well, first of all, consider those two words, "science" and "real." In our post-Kantian world, science cannot be "of the real," since there is an unbridgeable gulf between what is -- whatever that is -- and what we may know about it. The world is bifurcated into two domains, with science essentially reduced to what we can say about what our neurology says about a rumored "world" out there. To paraphrase Whitehead, the world is reduced to a dream at one end and conjecture at the other.
Yes, it sounds more than a little psychotic, but people will go to any length to avoid certain avenues of thought that lead to certain unwanted conclusions -- in this case, that no science of the real can exclude the Creator, or reality as such.
Anyway, Caldecott says that "In order for anything like modern science" -- I would just say "science" -- "to arise, it was necessary to believe in both the intelligibility of the cosmos and its contingency -- both the fact that it made sense, and the fact that it might not have existed."
So we see that science involves an element of absoluteness, which derives from the necessity of truth; but also of contingency, which derives from the infinite plenitude of the Creator. Thus, the world IS; but this IS cannot be self-sufficient, else it wouldn't be contingent (i.e., the world would be God).
Therefore, we see that the Isness of the world must be a kind of borrowed being, i.e., dependency on a higher principle.
Caldecott goes on to say that "Intelligibility alone would lead to the priority of deduction over induction, as in the ancient philosophies of nature where an observed reality... had to be conformed to a priori structures..."
This is why I do not call such an approach "science" per se, because it actually renders science impossible. Modern science is really something quite new, not traceable to ancient Greece.
In fact, I recall Rodney Stark making just this point in his For the Glory of God: How Monotheism Led to Reformations, Science, Witch-Hunts, and the End of Slavery. You hafta sorta not know what science is in order to believe the Greeks had it.
Note also that merely learning from the world empirically -- as helpful as that is -- isn't science either. Rather, real science -- or a science of the real -- must involve both: empirical observation of the world (of particulars) dynamically interacting with a more general logico-deductive system. This did not exist until the scientific revolution, which in turn only occurred in one place and at one time: in the Christian west.
Retrograde postmodernism is actually a rebellion -- or reactionary counter-revolution -- against the scientific world. Caldecott writes that "By separating real from rational entities, science from faith and God from nature, the via moderna of the nominalist philosophers from the 14th century onwards undermined natural philosophy and metaphysics."
In other words, the world is reduced to the world, so to speak, which has the perverse effect of elevating appearances to reality. But in the words of Davila, "The universe is important if it is appearance, and insignificant if it is reality." If the world is the reality, then it is nothing.
Here is the key point: "By arguing that nothing can exist but individual objects," the postmodern approach "effectively eliminated the 'vertical' or 'interior' dimension of reality -- the dimension of metaphysical form, final causality, and divine providence..." (Caldecott).
I would emphasize that the vertical IS the interior, and vice versa, so that to exclude one is to make nonsense of the other. Indeed, everything science can say about the world is rendered absurd by its own dim lights.
Truly, it is intellectual, or psychopneumatic, suicide -- except that it then leads to homicide and genocide. This is because the intellectual Zombies of Death convert their flatlandian superstitions into a religion, and persecute those who fail to recognize their strange gods.
Seriously, what is the IRS scandal but the leftist state-god systematically persecuting that half of the population which doesn't worship at that altar? This is why it is easily the worst scandal in the history of this country, because never before has this government -- which derives its just powers from the consent of the governed -- declared war on that half of the country which has the audacity to still believe such insolent nonsense.
Thus, for example, to teach the Constitution makes one an enemy of the state. But this is merely making fully explicit what has been implicit since Woodrow Wilson.
Aaaaaaaand, we're out of time.
