Cold completely introspective logic places a philosopher on the road to the abstract. Out of this empty, artificial act of thinking there can result, of course, nothing which bears on the relation of man to himself, and to the universe.

Most men are scantily nourished on a modicum of happiness and a number of empty thoughts which life lays on their plates. They are kept in the road of life through stern necessity by elemental duties which they cannot avoid.

From naive simplicity we arrive at more profound simplicity.

I can do no other than be reverent before everything that is called life. I can do no other than to have compassion for all that is called life. That is the beginning and the foundation of all ethics.

A man is ethical only when life, as such, is sacred to him, that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help.

Whatever you have received more than others-in health, in talents, in ability, in success, in a pleasant childhood, in harmonious conditions of home life-all this you must not take to yourself as a matter of course. In gratitude for your good fortune, you must remember in return some sacrifice of your own life for another life.

The thinking (person) must oppose all cruel customs, no matter how deeply rooted in tradition and surrounded by a halo. When we have a choice, we must avoid bringing torment and injury into the life of another.
