Leo Lopatin

Lev (Leo) Mikhailovich Lopatin was a Russian philosopher born in Moscow on June 13, 1855, and died in Moscow on March 21, 1920. He served as the head of the Moscow Psychological Society until its dissolution by the Soviet government after the 1917 Revolution. Lopatin's life was tragically cut short due to the widespread famine and Soviet reforms, leading to his death from malnourishment and exhaustion in 1920. He was a close friend and associate of Vladimir Soloviev, strongly identifying with and promoting Soloviev's philosophical ideas. Lopatin's own philosophical contributions are evident in his two-volume work, "The Positive Tasks of Philosophy" (1886). He also dedicated significant work to the concept of free will, exploring metaphysical libertarianism, although this work remained unpublished. His philosophical idealism was notably criticized by Vladimir Lenin in his book "Materialism and Empirio-criticism."
