“Humanity's true moral test, its fundamental test, consists of its attitude towards those who are at its mercy: animals. And in this respect humankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it.”

Mutual Aid: A Factor of Evolution (1902)
Context: It is especially in the domain of ethics that the dominating importance of the mutual-aid principle appears in full. That mutual aid is the real foundation of our ethical conceptions seems evident enough. But whatever the opinions as to the first origin of the mutual-aid feeling or instinct may be whether a biological or a supernatural cause is ascribed to it — we must trace its existence as far back as to the lowest stages of the animal world; and from these stages we can follow its uninterrupted evolution, in opposition to a number of contrary agencies, through all degrees of human development, up to the present times. Even the new religions which were born from time to time — always at epochs when the mutual-aid principle was falling into decay in the theocracies and despotic States of the East, or at the decline of the Roman Empire — even the new religions have only reaffirmed that same principle. They found their first supporters among the humble, in the lowest, downtrodden layers of society, where the mutual-aid principle is the necessary foundation of every-day life; and the new forms of union which were introduced in the earliest Buddhist and Christian communities, in the Moravian brotherhoods and so on, took the character of a return to the best aspects of mutual aid in early tribal life.
Each time, however, that an attempt to return to this old principle was made, its fundamental idea itself was widened. From the clan it was extended to the stem, to the federation of stems, to the nation, and finally — in ideal, at least — to the whole of mankind.

Environmentalism as a Religion (2003)
Context: Most of us have had some experience interacting with religious fundamentalists, and we understand that one of the problems with fundamentalists is that they have no perspective on themselves. They never recognize that their way of thinking is just one of many other possible ways of thinking, which may be equally useful or good. On the contrary, they believe their way is the right way, everyone else is wrong; they are in the business of salvation, and they want to help you to see things the right way. They want to help you be saved. They are totally rigid and totally uninterested in opposing points of view. In our modern complex world, fundamentalism is dangerous because of its rigidity and its imperviousness to other ideas.

The Enemies of Reason (August 2007)
Context: If any remedy is tested under controlled scientific conditions and proved to be effective, it will cease to be alternative and will simply become medicine. So-called alternative medicine either hasn’t been tested or it has failed its tests.

By regarding such productions as social facts the analyst is relieved of the burden of demonstrating what meanings these productions have for the artist and his audience. It is too frequently assumed that such meanings can be identified by a capable analyst, independent of the interpretations brought to such works by the artist or his audiences. In my judgement artist productions must be seen as interactional creations; the meanings of which arise out of the interactions directed to them by the artist and his audience.
