Many people when they fall in love look for a little haven of refuge from the world, where they can be sure of being admired when they are not admirable, and praised when they are not praiseworthy.

Love, children, and work are the great sources of fertilizing contact between the individual and the rest of the world

Civilized people cannot fully satisfy their sexual instinct without love

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

It [the world] must be a world in which affection has free play, in which love is purged of the instinct for domination, in which cruelty and envy have been dispelled by happiness and the unfettered development of all the instincts that build up life and fill it with mental delights. Such a world is possible; it waits only for men to wish to create it.

The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts.
