In 1896 Leo Tolstoy read "Thought and Reality" and was also deeply impressed, as he mentioned in a letter to Hélène Claparède-Spir: "reading "Thought and Reality" has been a great joy for me. I do not know a philosopher so profound and at the same time so precise, I mean scientific, accepting only what is strictly necessary and clear for everybody. I am sure that his doctrine will be understood and appreciated as it deserves and that the destiny of his work will be similar to that of Schopenhauer, who became known and admired only after his death".
