There will still be things that machines cannot do. They will not produce great art or great literature or great philosophy; they will not be able to discover the secret springs of happiness in the human heart; they will know nothing of love and friendship.

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

I consider the official Catholic attitude on divorce, birth control, and censorship exceedingly dangerous to mankind.
