A man is truly ethical only when he obeys the compulsion to help all life which he is able to assist, and shrinks from injuring anything that lives.

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

The great fault of all ethics hitherto has been that they believed themselves to have to deal only with the relations of man to man. In reality, however, the question is what is his attitude to the world and all life that comes within his reach.

In case my life should end with the cannibals, I hope they will write on my tombstone, 'We have eaten Dr. Schweitzer. He was good to the end.'

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.

One truth stands firm. All that happens in world history rests on something spiritual. If the spiritual is strong, it creates world history. If it is weak, it suffers world history.

Bach is thus a terminal point. Nothing comes from him; everything merely leads to him.
