To make his proposal easier to remember, Bentham devised what he called a “mnemonic doggerel” (also referred to as “memoriter verses”), which synthesized “the whole fabric of morals and legislation”:

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.
