We need a boundless ethic, one which will include the animals, too. Until we extend the circle of his compassions to all living things, we will not find peace.

When man learns to respect even the smallest being of creation...nobody has to teach him to love his fellow man. Compassion for animals is intimately connected with goodness of character, and it may be confidently asserted that he who is cruel to animals cannot be a good man.

The tragedy of life is what dies inside a man while he lives.

...try to tell the people of America about Dr. Gerson's merits and ...results...I wish you the best in your difficult task.

The only thing of importance, when we depart, will be the traces of love we have left behind.

In the past we have tried to make a distinction between animals which we acknowledge have some value and other which, having none, can be liquidated when we wish. This standard must be abandoned. Everything that lives has value simply as a living thing, as one of the manifestations of the mystery that is life.

We cannot understand what happens in the universe. What is glorious in it is united with what is full of horror. What is full of meaning is united to what is senseless. The spirit of the universe is at once creative and destructive — it creates while it destroys and destroys while it creates, and therefore it remains to us a riddle. And we must inevitably resign ourselves to this.
