Pushkin's friend, beloved, intimate, He was a friend of all the celebrities of his day,

His mind was a keen talker,

The circle of minds crowded around him.

Not only the author of these poems, Feodor Glinka, but also Pushkin and Yazykov, dedicated poems to him. He was a Freemason and a member of the Northern Society of the Decembrists, but fortunately for himself was abroad at the time of the uprising. It was he who “would have been Brutus in Rome, Pericles in Athens, but here he is a Hussar officer.” It was him who Pushkin addressed to: “Comrade, believe me, it will rise, the star of captivating happiness.” He is believed to be one of the possible prototypes of Chatsky. Years later it would turn out that the literary character had foretold the fate of his prototype: after the publication of the first of Chaadayev's Philosophical Letters, he was declared insane. Osip Mandelstam accurately remarked: “Chaadayev was the first Russian, indeed, ideologically, to have visited the West and to have found his way back.” Having raised the question of Russia's historical path, he had an enormous influence on the development of Russian philosophy. Chaadayev, a westernizer, actually initiated a polemic between the Westernizers and the Slavophiles, which greatly enriched the cultural life of Russia in the middle of the 19th century. And to all reproaches that Russia was alien to him and that he did not love his homeland and spoke ill of it, Chaadayev answered aphoristically: “Thank God, I have always loved my fatherland in its interests, not in my own.”
