Author: Leon Trotsky
'In Defence of Marxism' is the record of Trotsky's struggle against the petty-bourgeois opposition in the Socialist Workers' Party (USA) in 1939. It concerns the class nature of the Soviet state and the fundamentals of Marxism.
In this last major struggle of Trotsky's life, he carries forward the fight for Bolshevism in the Fourth International against the revisionist representatives of bourgeois class interests. His defence of dialectical materialism against the pragmatist outlook of the American radical intelligensia is an indispensible part of the heritage of Trotskyism, the Marxism of today.
