Man errs as long as he strives.

You are, when all is done-just what you are.

Strike the dog dead, it's but a critic!

The day is for mistake and error, sequence of time for success and carrying out. The one who anticipates is master of the day.

The person who in shaky times also wavers only increases the evil, but the person of firm decision fashions the universe.

Man... knows only when he is satisfied and when he suffers, and only his sufferings and his satisfactions instruct him concerning himself, teach him what to seek and what to avoid. For the rest, man is a confused creature; he knows not whence he comes or whither he goes, he knows little of the world, and above all, he knows little of himself.

The phrases that men hear or repeat continually, end by becoming convictions and ossify the organs of intelligence.
