Neither irony or sarcasm is argument.
We are not won by arguments that we can analyse but by tone and temper, by the manner which is the man himself.
Man is the only animal that laughs and has a state legislature.
A friend who cannot at a pinch remember a thing or two that never happened is as bad as one who does not know how to forget.
All animals, except man, know that the principal business of life is to enjoy it.
Life is not an exact science, it is an art.
