Man's ethics must not end with man, but should extend to the universe. He must regain the consciousness of the great Chain of Life from which he cannot be separated.

A man can do only what he can do. But if he does that each day he can sleep at night and do it again the next day.

To the man who is truly ethical all life is sacred, including that which from the human point of view seems lower in the scale. He makes distinctions only as each case comes before him, and under the pressure of necessity, as, for example, when it falls to him to decide which of two lives he must sacrifice in order to preserve the other. But all through this series of decisions he is conscious of acting on subjective grounds and arbitrarily, and knows that he bears the responsibility for the life which is sacrificed.

The city of truth cannot be built on the swampy ground of skepticism.

Serious illness doesn't bother me for long because I am too inhospitable a host.

We cannot possibly let ourselves get frozen into regarding everyone we do not know as an absolute stranger.

Thought cannot avoid the ethical or reverence and love for all life. It will abandon the old confined systems of ethics and be forced to recognize the ethics that knows no bounds. But on the other hand, those who believe in love for all creation must realize clearly the difficulties involved in the problem of a boundless ethic and must be resolved not to veil from humankind the conflicts which this ethic will involve us, but allow us really to experience them. To think out in every implication the ethic of love for all creation this is the difficult task which confronts our age.
