Vasiliy Vasilievich Nalimov (Васи́лий Васи́льевич Нали́мов; 4 November 1910 – 19 January 1997) was a Russian philosopher and humanist and wrote on Transpersonal Psychology. His main areas of research were the philosophy of probability and its biological, mathematical, and linguistic manifestations. He also studied the roles of gnosticism and mysticism in science. Thompson (1993) summarizes Nalimov as: "...philosopher, educator, devoted husband, mathematician, dissident, writer, and (although he may deny it) visionary".
