“From the standpoint of observation, then, we must regard it as a highly probable hypothesis that the beginnings of the mental life date from as far back as the beginnings of life at large.”

Interview in Speaking of Science Fiction: The Paul Walker Interviews (1978)
Context: When I talk of the purpose of life, I am thinking not only of human life, but of all life on Earth and of the life which must exist upon other planets throughout the universe. It is only of life on Earth, however, that one can speak with any certainty. It seems to me that all life on Earth, the sum total of life upon the Earth, has purpose. If the means were available, we could trace our ancestry — yours and mine — back to the first blob of life-like material that came into being on the planet. The same thing could be done for the spider that spun his web in the grass, and of the grass in which the web was spun, the bird sitting in the tree and the tree in which he sits, the toad waiting for the fly beneath the bush, and for the fly and bush. We are all genetic brothers. The chain of life, tracing back to that primordial day of life's beginning, is unbroken...

The sooner we begin this process of healing as people, all people, the sooner we can begin to live a mutual life free from innuendo, hurt, judgment and need.

Anarchism: Its Philosophy and Ideal (1896)
Context: 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.
