This tutorial is not like a textbook in the usual sense of the word. This is an attempt to systematize all known philosophical theories - from ancient times to the present day - and build them into a universal "periodic system of philosophy. "Thanks to this approach, the reader will be able to "collect" fragmentary, disparate knowledge about philosophy into a single scheme, where each worldview, each direction, each era is assigned a certain place. Such a systematic vision of the subject allows you to judge it from the point of view of a specialist, not an amateur. The book is intended for undergraduate and graduate students, as well as for readers who are interested in philosophy.
