"A soon as we study animals — not in laboratories and museums only, but in the forest and prairie, in the steppe and in the mountains — we at once perceive that though there is an immense amount of warfare and extermination going on amidst various species, and especially amidst various classes of animals, there is, at the same time, as much, or perhaps even more, of mutual support, mutual aid, and mutual defence amidst animals belonging to the same species or, at least, to the same society. Sociability is as much a law of nature as mutual struggle. Of course it would be extremely difficult to estimate, however roughly, the relative numerical importance of both these series of facts. But if we resort to an indirect test, and ask Nature: "Who are the fittest: those who are continually at war with each other, or those who support one another?" we at once see that those animals which acquire habits of mutual aid are undoubtedly the fittest. They have more chances to survive, and they attain, in their respective classes, the highest development and bodily organization. If the numberless facts which can be brought forward to support this view are taken into account, we may safely say that mutual aid is as much a law of animal life as mutual struggle; but that as a factor of evolution, it most probably has a far greater importance, inasmuch as it favors the development of such habits and characters as insure the maintenance and further development of the species, together with the greatest amount of welfare and enjoyment of life for the individual, with the least waste of energy."

“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?”
