Animal protection is education to the humanity.

Living truth is that alone which has its origins in thinking. Just as a tree bears year after year the same fruit which is each year new, so must all permanently valuable ideas be continually born again in thought.

The greatest living person in the world is some individual who at this very moment has gone in love to help another.

Everything deep is also simple and can be reproduced simply as long as its reference to the whole truth is maintained. But what matters is not what is witty but what is true.

The thinking man must oppose all cruel customs no matter how deeply rooted in tradition or surrounded by a halo. We need a boundless ethics which will include the animals also. My life is full of meaning to me. The life around me must be full of significance to it. If I want others to respect my life, then I must respect the other life I see however strange it may be to mine. Ethics in our western world has hitherto been largely limited to the relation of man to man... but that is a limited ethics.

What we call love is in its essence reverence for life.

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.
