"In the animal world we have seen that the vast majority of species live in societies, and that they find in association the best arms for the struggle for life: understood, of course, in its wide Darwinian sense — not as a struggle for the sheer means of existence, but as a struggle against all natural conditions unfavourable to the species. The animal species, in which individual struggle has been reduced to its narrowest limits, and the practice of mutual aid has attained the greatest development, are invariably the most numerous, the most prosperous, and the most open to further progress. The mutual protection which is obtained in this case, the possibility of attaining old age and of accumulating experience, the higher intellectual development, and the further growth of sociable habits, secure the maintenance of the species, its extension, and its further progressive evolution. The unsociable species, on the contrary, are doomed to decay."

“The confused mass of rules of conduct called law, which has been bequeathed to us by slavery, serfdom, feudalism, and royalty, has taken the place of those stone monsters, before whom human victims used to be immolated, and whom slavish savages dared not even touch lest they should be slain by the thunderbolts of heaven.”

“There are periods in the life of human society when revolution becomes an imperative necessity, when it proclaims itself as inevitable. New ideas germinate everywhere, seeking to force their way into the light, to find an application in life; everywhere they are opposed by the inertia of those whose interest it is to maintain the old order; they suffocate in the stifling atmosphere of prejudice and traditions.”

“We are beginning to see that government by majorities means abandoning all the affairs of the country to the tide-waiters who make up the majorities in the House and in election committees; to those, in a word, who have no pinion of their own.”

“To begin with, if man, since his origin, has always lived in societies, the State is but one of the forms of social life, quite recent as far as regards European societies. Men lived thousands of years before the first States were constituted; Greece and Rome existed for centuries before the Macedonian and Roman Empires were built up, and for us modern Europeans the centralized States date but from the sixteenth century. It was only then, after the defeat of the free mediæval Communes had been completed that the mutual insurance company between military, judicial, landlord, and capitalist authority which we call "State," could be fully established.”

“Have not prisons — which kill all will and force of character in man, which enclose within their walls more vices than are met with on any other spot of the globe — always been universities of crime? Is not the court of a tribunal a school of ferocity?”
