“Darwin did not know what a bitter satire he wrote on mankind ... when he showed that free competition, the struggle for existence, which the economists celebrate as the highest historical achievement, is the normal state of the animal kingdom. Only conscious organization of social production, in which production and distribution are carried on in a planned way, can lift mankind above the rest of the animal.”

“In the social production of their existence, men inevitably enter into definite relations, which are independent of their will, namely relations of production appropriate to a given stage in the development of their material forces of production. The totality of these relations of production constitutes the economic structure of society, the real foundation, on which arises a legal and political superstructure and to which correspond definite forms of social consciousness. The mode of production of material life conditions the general process of social, political and intellectual life. It is not the consciousness of men that determines their existence, but their social existence that determines their consciousness. At a certain stage of development, the material productive forces of society come into conflict with the existing relations of production or – this merely expresses the same thing in legal terms – with the property relations within the framework of which they have operated hitherto. From forms of development of the productive forces these relations turn into their fetters. Then begins an era of social revolution. The changes in the economic foundation lead sooner or later to the transformation of the whole immense superstructure.”

“Solitude, competitiveness and grief are the unavoidable lot of a writer only when there is no organization or network to which he can turn.”

“The 'Manifesto' being our joint production, I consider myself bound to state that the fundamental proposition which forms its nucleus belongs to Marx. That proposition is: that in every historical epoch, the prevailing mode of economic production and exchange, and the social organization necessarily following from it, form the basis upon which is built up, and from which alone can be explained, the political and intellectual history of that epoch; that consequently the whole history of mankind (since the dissolution of primitive tribal society, holding land in common ownership) has been a history of class struggles, contests between exploiting and exploited, ruling and oppressed classes; that the history of these class struggles forms a series of evolution in which, nowadays, a stage has been reached where the exploited and the oppressed class—the proletariat—cannot attain its emancipation from the sway of the exploiting and ruling class—the bourgeoisie—without, at the same time, and once for all, emancipating society at large from all exploitation, oppression, class distinctions and class struggles.This proposition, which, in my opinion, is destined to do for history what Darwin's theory has done for biology, we, both of us, had been gradually approaching for some years before 1845.”

“Brutality to an animal is cruelty to mankind - it is only the difference in the victim.”

“The transformation of the community into an administrative state responsible for total social welfare leads to a paternal totality without a house-father when it fails to find any archy or cracy that is more than a mere nomos of distribution and production. I consider it to be a utopia when Friedrich Engels promises that one day all power of men over men will cease, that there will be only production and consumption with no problems, and that "things will govern themselves." This things-governing-themselves will make every archy and cracy super­fluous , and demonstrate that mankind at last has found its formula, just as, according to Dostoyevsky, the bees found their formula in the beehive, because animal s, too, have their nomos. Most of those who swarm around a nomos basileus fail to notice that, in reality, they propagate just such a formula.”
