The logician E. Kant it is written down by his students of Kenigbersky university on his lectures on logic. This book is published in Germany in the 19th century and long ago is translated into different languages of the world from German.
The logician L. Tolstoy contains in his book "Confession" which has been published in the 19th century and also is translated into different languages of the world from Russian long ago.
In what a difference in Kant and Tolstoy's approaches? Why it is possible to draw a conclusion that the great Russian writer and the poet A. Pushkin read E. Kant, and the great Russian writer L. Tolstoy didn't read E. Kant?
Sincerely, Alexander.
