The trouble with taxonomic boxes is... that that they tend to be empty, however beautiful they are on the outside.

The evolutionary vision is agnostic in regard to systems in the universe of greater complexity than those of which human beings have clear knowledge. It recognizes aesthetic, moral, and religious ideas and experiences as a species, in this case of mental structures or of images, which clearly interacts with other species in the world's great' ecosystem.

One reason why the progressive state is 'cheerful' is that social conflict is diminished by it.

Political conflict rests to a very large extent on a universal ignorance of consequences, as the people who are benefited by any particular act or policy are rarely those who struggled for it, and the people who are injured are rarely those who opposed it.

Physicists can only talk to other physicists and economists to economists... sociologists often cannot even understand each other.

Communication can only take place among equals.

Are we to regard the world of nature simply as a storehouse to be robbed for the immediate benefit of man?
