“It was all right to be sad. It was all right to lament. It was all right to feel anger. But [is] not all right to run away.”

On President Richard Nixon’s visit to China (5 October 1971), as quoted in Simpson's Contemporary Quotations (1988) edited by James Beasley Simpson.

The Life Process is the End—not man, nor any other animal temporarily privileged to weave a world's philosophy. Non-human beings were not made for human beings any more than human beings were made for non-human beings. Just as the sidereal spheres were once supposed by the childish mind of man to be unsubstantial satellites of the earth, but are known by man's riper understanding to be worlds with missions and materialities of their own, and of such magnitude and number as to render terrestrial insignificance frightful, so the billions that dwell in the seas, fields, and atmospheres of the earth were in like manner imagined by the illiterate children of the race to be the mere trinkets of men, but are now known by all who can interpret the new revelation to be beings with substantially the same origin, the same natures, structures, and occupations, and the same general rights to life and happiness, as we ourselves.
