[I am] at heart more of a United-States-man than an Englishman. - Jeremy Bentham

Intense, long, certain, speedy, fruitful, pure—
Such marks in pleasures and in pains endure.
Such pleasures seek if private be thy end:
If it be public, wide let them extend.
Such pains avoid, whichever be thy view:
If pains must come, let them extend to few.

[P]leasure is in itself a good; nay, even setting aside immunity from pain, the only good: pain is in itself an evil; and, indeed, without exception, the only evil; or else the words good and evil have no meaning. And this is alike true of every sort of pain, and of every sort of pleasure.

[I]n principle and in practice, in a right track and in a wrong one, the rarest of all human qualities is consistency.
