Sincerity that thinks it is the sole possessor of the truth is a deadlier sin than hypocrisy, which knows better.

The three hardest tasks in the world are neither physical feats nor intellectual achievements, but moral acts: to return love for hate, to include the excluded, and to say, 'I was wrong'.

Usually, if we hate, it is the shadow of the person that we hate, rather than the substance. We may hate a person because he reminds us of someone we feared and disliked when younger; or because we see in him some gross caricature of what we find repugnant in ourself; or because he symbolizes an attitude that seems to threaten us.

Honesty consists of the unwillingness to lie to others; maturity, which is equally hard to attain, consists of the unwillingness to lie to oneself.

All significant achievement comes from daring from experiment from the willingness to risk failure.
