It is within science itself, and not in some prior philosophy, that reality is to be identified and described.

It seems to me that science has a much greater likelihood of being true in the main than any philosophy hitherto advanced (I do not, of course, except my own). In science there are many matters about which people are agreed; in philosophy there are none. Therefore, although each proposition in a science may be false, and it is practically certain that there are some that are false, yet we shall be wise to build our philosophy upon science, because the risk of error in philosophy is pretty sure to be greater than in science. If we could hope for certainty in philosophy, the matter would be otherwise, but so far as I can see such a hope would be chimerical.
Bertrand Russell
The recognition of the light of reality within the darkness of abstraction is a contradiction – both the affirmation and the negation of the real at one and the same time. The new philosophy, which thinks the concrete not in an abstract but a concrete way, which acknowledges the real in its reality – that is, in a way corresponding to the being of the real as true, which elevates it into the principle and object of philosophy – is consequently the truth of the Hegelian philosophy, indeed of modern philosophy as a whole.
Ludwig Andreas Feuerbach
The criticism of the German philosophy of state and right, which attained its most consistent, richest, and last formulation through Hegel, is both a critical analysis of the modern state and of the reality connected with it, and the resolute negation of the whole manner of the German consciousness in politics and right as practiced hereto, the most distinguished, most universal expression of which, raised to the level of science, is the speculative philosophy of right itself.
Georg Wilhelm Friedrich Hegel
Not only must philosophy be in agreement with our empirical knowledge of Nature, but the origin and formation of the Philosophy of Nature presupposes and is conditioned by empirical physics. However, the course of a science's origin and the preliminaries of its construction are one thing, while the science itself is another. In the latter, the former can no longer appear as the foundation of the science; here, the foundation must be the necessity of the Concept.
Georg Wilhelm Friedrich Hegel
The Western approach to reality is mostly through theory, and theory begins by denying reality — to talk about reality, to go around reality, to catch anything that attracts our sense-intellect and abstract it away from reality itself. Thus philosophy begins by saying that the outside world is not a basic fact, that its existence can be doubted and that every proposition in which the reality of the outside world is affirmed is not an evident proposition but one that needs to be divided, dissected and analyzed. It is to stand consciously aside and try to square a circle.
