My personal conviction is that science is concerned wholly with truth, not with ethics.

We shall never understand the ethical system taught by Jesus unless we realize that he was a Jew, not only by birth, but that he lived and taught as a Jew; the Sermon on the Mount was addressed to his distracted fellow nationals.

Whichever theory we adopt to give a rational explanation of human existence, that theory must take into account and explain the mental nature we see at work in all modern communities.

Civilization, we shall find, like Universalism and Christianity, is anti evolutionary in its effects; it works against the laws and conditions which regulated the earlier stages of man's ascent.

A drunkard is one thing, and a temperate man is quite another.

There are the further difficulties of building a population out of a diversity of races, each at a different stage of cultural evolution, some in need of restraint, many in need of protection; everywhere a bewildering Babel of tongues.

Tolerance is held to be a condition of mind which is encouraged by, and is necessary for, civilization.
