The fact that altruism has been evolved by the cooperation of individuals with each other and against others is a significant fact in the analysis an… - J. Howard Moore

Zoocentricism, that stage of solidarity in which the entire sentient universe is contemplated, universal consideration and love, is as yet too difficult for human consciousness. Human philosophy, which has been so slow in discovering the solidarity of the human species, is to-day, except in its Oriental manifestations, as reluctant to recognize other species in its ethical contemplations as were dominant human groups in less advanced stages of aggregation reluctant to recognize the solidarity of the hominine species.

The doctrine of organic evolution, which forever established the common genesis of all animals, sealed the doom of anthropocentricism. Whatever the inhabitants of this world were or were thought to be before the publication of 'The Origin of Species,' they never could be anything since then but a family. The doctrine of evolution is probably the most important revelation that has come to the world since the illuminations of Galileo and Copernicus. The authors of the Copernican theory enlarged and corrected human understanding by disclosing to man the comparative littleness of his world—by discovering that the earth, which had up to that time been supposed to be the centre and capital of cosmos, is in reality a satellite of the sun. This heliocentric discovery was hard on human conceit, for it was the first broad hint man had thus far received of his true dimensions. The doctrine of evolution has had, and is having, and is destined to continue to have, a similarly correcting effect on the naturally narrow conceptions of men.

The great trouble is that individuals and races in their treatment of each other are not guided by the same high standards of impartiality as an individual organism in dealing with his own organs and parts. Life is not one. It lacks unity of feeling and purpose. And as long as it lacks this oneness it will lack justice.
