In the animal kingdom, the rule is, eat or be eaten;
in the human kingdom, define or be defined.
When a person can no longer laugh at himself,
it is time for others to laugh at him.
The stupid neither forgive nor forget;
the naive forgive and forget;
the wise forgive but do not forget.

Boredom is the feeling that everything is
a waste of time; serenity, that nothing is.
Punishment is now unfashionable… because it creates moral distinctions among men, which, to the democratic mind, are odious. We prefer a meaningless collective guilt to a meaningful individual responsibility.
Knowledge is gained by learning;
trust by doubt;
skill by practice;
and love by love.
