futility, n.All

Confucius say ... man piss in wind, wind piss back

Futility is best to be recognized — puff not against the wind.

Futility is, in love, not a weakness or an absurdity: It is a strong sign: The more futile, the more it signifies and the more it asserts itself as strength.

Futility is by no means futile — all men know the utility of useful things, but know not the utility of futility.
