To work for the common good is the greatest creed.

Compassion, in which all ethics must take root, can only attain its full breadth and depth if it embraces all living creatures and does not limit itself to mankind.

If you love what you are doing, you will be successful.

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.

Even if it is a little thing, do something for those who have need of help.

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

Our degeneration, when it is traced back to its origin in our view of the world really consists in the fact that true optimism has vanished unperceived from our midst.
