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.

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

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.

In every man there is an instinctive and passionate reaction if his person or liberty is attacked.

In a tribal organization, even in time of peace, service to tribe or state predominates over all self seeking; in war, service for the tribe or state becomes supreme, and personal liberty is suspended.

The course of human history is determined, not by what happens in the skies, but what takes place in our hearts.

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