I think that somehow, we learn who we really are and then live with that decision.

It is better to light a candle than curse the darkness.

Usefulness, whatever form it may take, is the price we should pay for the air we breathe and the food we eat and the privilege of being alive.

It seems to me of great importance to teach children respect for life. Towards this end, experiments on living animals in classrooms should be stopped. To encourage cruelty in the name of science can only destroy the finer emotions of affection and sympathy, and breed an unfeeling callousness in the young towards suffering in all living creatures.

Nothing was ever accomplished by anyone who said 'It can't be done.'

Think as little as possible about yourself and as much as possible about other people.

I think it is impossible for one human being really to know another without first knowing and being at peace with himself.
