In the appendix to my History of the Russian Revolution I give a detailed and documented study of the ideas of the Bolshevik party on the October revolution. This study, I hope, will make it impossible in the future to ascribe to [Vladimir] Lenin the theory of Socialism in a single country.

Workers – men and women – of all countries, place yourselves under the banner of the Fourth International. It is the banner of your approaching victory!

As a general rule, man strives to avoid labor. Love for work is not at all an inborn characteristic: it is created by economic pressure and social education. One may even say that man is a fairly lazy animal. It is on this quality, in reality, that is founded to a considerable extent all human progress; because if man did not strive to expend his energy economically, did not seek to receive the largest possible quantity of products in return for a small quantity of energy, there would have been no technical development or social culture.

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

The basis of bureaucratic rule is the poverty of society in objects of consumption, with the resulting struggle of each against all. When there is enough goods in a store, the purchasers can come whenever they want to. When there is little goods, the purchasers are compelled to stand in line. When the lines are very long, it is necessary to appoint a policeman to keep order. Such is the starting point of the power of the Soviet bureaucracy. It "knows" who is to get something and who has to wait.

Can and must! The proclamation of this new conception of [Joseph Stalin] is closed by the same words, "Such are in general the characteristic features of Lenin's conception of the proletarian revolution." In the course of a single year Stalin ascribed to [Vladimir] Lenin two directly opposed conceptions of the fundamental question of socialism. The first version represents the real tradition of the party; the second took shape in Stalin's mind only after the death of Lenin, in the course of the struggle against "Trotskyism".

Communism needs democracy like the human body needs oxygen.
