In his (2 May 1896) Tolstoy wrote: "Still another important event the work ["Thought and Reality"] of African Spir. I just read through what I wrote in the beginning of this notebook. At bottom, it is nothing else than a short summary of all of Spir's philosophy which I not only had not read at that time, but about which I had not the slightest idea. This work clarified my ideas on the meaning of life remarkably, and in some ways strengthened them. The essence of his doctrine is that things do not exist, but only our impressions which appear to us in our conception as objects. Conception (Vorstellung) has the quality of believing in the existence of objects. This comes from the fact that the quality of thinking consists in attributing an objectivity to impressions, a substance, and a projecting of them into space". The next day (3 May 1896) he added, "I am reading Spir all the time, and the reading provokes a mass of thoughts".
