Aleksandr Konstantinovich Voronsky was a prominent humanist Marxist literary critic, theorist and editor of the 1920s, disfavored and purged in 1937 for his work with the Left Opposition and Leon Trotsky during and after the October Revolution. Voronsky's writings were hidden away in the Soviet Union, until his autobiography, Waters of Life and Death, and anthology, Art as the Cognition of Life were translated and published in English.
