Yevgeny Trubetskoy

Prince Evgeny Nikolayevitch Trubetskoy 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. Trubetskoy studied law at Moscow University, graduating in 1885, and soon turned to philosophy. In 1892 he earned a master's degree in philosophy on a study of Augustine, and later a doctorate (1897) for work on Pope Gregory VII.
