Abstract

Having accepted the heritage of the Greek “phisikoi”, science is increasing knowledge faster than the consequences of its application are recognized. This gives the demand of the full conditions unit, when the theoretical knowledge can receive the interpretation and can be realized in artifacts. The problem of blind-spots search in methodology became the task of the second part of XX century. As a result appeared the deepened classical principles of cognition and the new ones were designed. Uniting of all the basis in joint epistemological corpus is the most important task of the modern philosophy of science. In the paper the fundamental principles, which constitute the basis of epistemological corpus, are observed: 1.The abstraction principle in depth understanding of the theory as a structure of abstractions. 2. Leibniz-Heidegger principle of sufficient reason in terms of its connection to the systems paradigm. 3. The systems principle in the meaning of the system as a universal link form of the things being reasoned and the reasons, as a universal form of object representation. 4. The intervality principle, which determines the theory limits through the interval characteristics based on the concept of “abstraction interval”. The logical connection of the above mentioned principles, which form the type of productive thinking both on the way to knowledge and on the life way, is established.
