The growth of the human mind is still high adventure, in many ways the highest adventure on earth.

The heart of the matter is that some people like to cause injury or death to living things. And many of those who do not are indifferent to those who do.

The need is not to amputate the ego ... but to transcend it.

The individual is capable of both great compassion and great indifference. He has it within his means to nourish the former and outgrow the latter.

Ten minutes of genuine belly laughter had an anesthetic effect and would give me at least two hours of pain-free sleep.

My reason nourishes my faith and my faith my reason.

History is an accumulation of error.
