Leon Trotsky — "A party is a part of a class."

"The depth and strength of a human character are defined by its moral reserves. People reveal themselves completely only when they are thrown out of the customary conditions of their life."

"The national program of the proletariat in the underdeveloped countries can be successful only as a stage in the international revolution."

"The working class must organize itself as the ruling class."

"The bureaucracy in the Soviet Union is not a class, but a parasitic growth on the workers' state."

"The working class cannot simply lay hold of the ready-made state machinery, and wield it for its own purposes."
