Pyotr or Petr Yakovlevich Chaadayev (Russian: Пётр Я́ковлевич Чаада́ев; also spelled Chaadaev, or Čaadajev; 7 June [27 May O.S.] 1794 – 26 April [14 April O.S.] 1856) was a Russian philosopher. He was one of the Russian Schellingians.[1]
Chaadayev wrote eight "Philosophical Letters"[2] about Russia in French between 1826 and 1831, which circulated among intellectuals in Russia in manuscript form for many years. They comprise an indictment of Russian culture for its laggard role far behind the leaders of Western civilization. He cast doubt on the greatness of the Russian past, and ridiculed Orthodoxy for failing to provide a sound spiritual basis for the Russian mind. He extolled the achievements of Europe, especially in rational and logical thought, its progressive spirit, its leadership in science, and indeed its leadership on the path to freedom.
The Russian government saw his ideas as dangerous and unsound. After some were published, they were all banned by the censorship process. Because there was nothing to charge him with, Chaadayev was declared legally insane and put under constant medical supervision, though this was a formality rather than a real administrative abuse.[3]
