Humanity today is not safe in the presence of humanity. The old cannibalism has given way to anonymous action in which the killer and the killed do not know each other, and in which,indeed, the very fact of mass death has the effect of making mass killing less reprehensible than the death of a single individual. In short, we have evolved in every respect except our ability to protect ourselves against human intelligence. Our knowledge is vast but does not embrace the workings of peace.

A human being fashions his consequences as surely as he fashions his goods or his dwelling. Nothing that he says, thinks or does is without consequences.

No one really knows enough to be a pessimist.

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

The human body experiences a powerful gravitational pull in the direction of hope. That is why the patient's hopes are the physician's secret weapon. They are the hidden ingredients in any prescription.

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.

Respect for the fragility and importance of an individual life is still the mark of an educated man.
