From the science disunity to the first steps of its integration

Since its inception, philosophy has been engaged in comprehending the unity of the world, and its main focus was determined by the intention to reduce to a single basis all the changing diversity of not only natural, but also social phenomena. But that didn't happen. Thus, the search for grounds for the integration of natural science and humanities knowledge is currently a rather serious problem, which has no theoretical solution yet. To solve the problem of integration of knowledge, I propose a new conceptual apparatus of philosophy in the form of a cumulative series of comparative concepts lying between the ultimate abstractions of identification and distinction, which are the concepts of "identity" and "difference".
