Leon Trotsky — "The fate of the revolution depends on the international proletariat."

"The revolution is a struggle for ideas, but it is also a struggle for power."

"The historical ascent of humanity, taken as a whole, may be summarized as a succession of victories of consciousness over blind forces — in nature, in society, in man himself."

"The revolution is not a dinner party, not an essay, not a painting, not a embroidery; it cannot be so refined, so leisurely and gentle, so 'benign', 'courteous', 'restrained' and 'magnanimous'."

"The revolution demands all of a man; it does not tolerate half-measures."

"If I am not I, then who is I?"
