When people have light in themselves, it will shine out from them. Then we get to know each other as we walk together in the darkness, without needing to pass our hands over each other's faces, or to intrude into each other's hearts.

Man can hardly even recognize the devils of his own creation.

Let me give you a definition of ethics: It is good to maintain and further life it is bad to damage and destroy life.

We are united with all life that is in nature. Man can no longer live his life for himself alone.

The true worth of a man is not to be found in man himself, but in the colours and textures that come alive in others.

Today it is considered as exaggeration to proclaim constant respect for every form of life as being the serious demand of a rational ethic. But the time is coming when people will be amazed that the human race existed so long before it recognized that thoughtless injury to life is incompatible with real ethics. Ethics is in its unqualified form extended responsibility to everything that has life.

The highest knowledge is to know that we are surrounded by mystery.
