National self-sufficiency or "autarchy" is the ideal of [Adolf] Hitler, not of [Karl] Marx and [Vladimir] Lenin.

Technique is noticed most markedly in the case of those who have not mastered it.

As long as human labor power, and, consequently, life itself, remain articles of sale and purchase, of exploitation and robbery, the principle of the “sacredness of human life” remains a shameful lie, uttered with the object of keeping the oppressed slaves in their chains.

Revolutions are always verbose.

The clearer and deeper the public opinion of the world, in the first instance the opinion of the working masses, will understand the contradictions and the difficulties of the socialist development of an isolated country, the higher will it appreciate the results achieved. The less it identifies the fundamental methods of Socialism with the zigzags and errors of the Soviet bureaucracy, the less will be the danger that, by the inevitable revelation of these errors and of their consequences, the authority, not only of the present ruling group, but of the workers' State itself, may decline.

The main task of Socialism - the organization of Socialist production - remains still in the future.
