The third volume of the anniversary edition is entirely devoted to Kant’s main work - “Critique of Pure Reason”. The classic translation of N. Lossky has been restored, as far as possible. The translation has been scrupulously checked against the original, and the necessary terminological clarifications have been included. The text of the second lifetime edition of Kant's work is traditionally reproduced; significant excerpts from the first edition are given in the appendices. In both cases, the pagination of the first editions is given in the margins (which is usually used to provide references in Kant studies literature). The notes have been rewritten and significantly expanded.
