All the parties of capitalist society, all its moralists and all its sycophants will perish beneath the debris of the impending catastrophe. The only party that will survive is the party of the world socialist revolution...

Let us not forget that revolutions are accomplished through people, although they be nameless. Materialism does not ignore the feeling, thinking, and acting man, but explains him.

The Soviet Union needs thinking and critical friends, such as are capable not only of singing hymns in the hours of success, but of not shrinking in the hour of defeat and danger.

Dialectical thought is related to vulgar thinking in the same way that a motion picture is related to a still photograph. The motion picture does not outlaw the still photograph but combines a series of them according to the laws of motion.

The dialectic is neither fiction or mysticism, but a science of the forms of our thinking insofar as it is not limited to the daily problems of life but attempts to arrive at an understanding of more complicated and drawn-out processes. The dialectic and formal logic bear a relationship similar to that between higher and lower mathematics.

There are no absolute rules of conduct, either in peace or war. Everything depends on circumstances.

A program of "disarmament," while imperialist antagonisms survive, is the most pernicious of fictions. Even if it were realized by way of general agreement - an obviously fantastic assumption!- that would by no means prevent a new war. The imperialists do not make war because there are armaments; on the contrary, they forge arms when they need to fight.

The slanders poured down like Niagara. If you take into consideration the setting - the war and the revolution - and the character of the accused - revolutionary leaders of millions who were conducting their party to the sovereign power - you can say without exaggeration that July 1917 was the month of the most gigantic slander in world history.

To renounce the conquest of power is voluntarily to leave the power with those who wield it, the exploiters. The essence of every revolution consisted and consists in putting a new class in power, thus enabling it to realize its own program in life. It is impossible to wage war and to reject victory.

The struggle against war and its social source, capitalism, presupposes direct, active, unequivocal support to the oppressed colonial peoples in their struggles and wars against imperialism. A 'neutral' position is tantamount to support of imperialism.

History has different yardsticks for the cruelty of the Northerners and the cruelty of the Southerners in the Civil War. A slave-owner who through cunning and violence shackles a slave in chains, and a slave who through cunning or violence breaks the chains – let not the contemptible eunuchs tell us that they are equals before a court of morality!
