A happy life must be to a great extent a quiet life, for it is only in an atmosphere of quiet that true joy dare live.

Italy, and the spring and first love all together should suffice to make the gloomiest person happy.

The main thing needed to make men happy is intelligence.

Contempt for happiness is usually contempt for other people's happiness, and is an elegant disguise for hatred of the human race.

The secret to happiness is to face the fact that the world is horrible.

Any pleasure that does no harm to other people is to be valued.

Public opinion is always more tyrannical towards those who obviously fear it than towards those who feel indifferent to it.

Few people can be happy unless they hate some other person, nation, or creed.

The main things which seem to me important on their own account, and not merely as means to other things, are knowledge, art, instinctive happiness, and relations of friendship or affection.
