The book is devoted to virtue epistemology - one of the leading directions of modern analytical epistemology. For the first time in the Russian philosophical tradition, a critical systematic analysis of the basic concepts of virtue epistemology was carried out (E. Goldman, E. Souza, D. Pritchard, J. Greco, L. Zagzebski, J. Bayer, etc.). The book substantiates a two-level concept of intellectual virtues, which manifests itself in the integration of two types of cognitive perfections: 1) general cognitive abilities and 2) individual qualities of an intellectual character. Aretic contextualism is proposed, within which the subject of attribution of knowledge (expert) should be an intellectually virtuous person, since it is such a subject of knowledge that can assess the epistemic significance of the context. The author's interpretation of key epistemic virtues was carried out, which creates a theoretical basis for a new direction of research in the theory of knowledge - the intellectual ethos of knowledge. It has been shown that the most effective epistemological position of a subject participating in collective cognition is the one based on the intellectual virtue of trust. The book is addressed to specialists in the field of theory of knowledge and modern analytical philosophy, as well as to all readers who think and care about knowledge.
