Evgenii Troubetzkoy

Prince Evgenii Nikolaevitch Troubetzkoy (Евге́ний Никола́евич Трубецко́й; 5 October 1863 – 5 February 1920) was a Russian philosopher and a follower of Vladimir Solovyov. He was the son of Prince Nikolai Petrovitch Trubetskoy, co-founder of the Moscow Conservatory, and Sophia Alekseievna Lopouchina. His mother was a big influence on his religious thought. He was close to his brother, Sergei Nikolaevich Trubetskoy, who was also a philosopher.

Russian paleontologist and Christian apologist Alexander V. Khramov (Borissiak Paleontological Institute of the Russian Academy of Sciences, Ph.D. from Moscow University) attributes his ideas about an atemporal human fall to Troubetzkoy and Nikolai Berdyaev.
