Bentham's "mnemonic doggerel"
or "memoriter verses"
"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."
(1748 - 1832)
