In other words, according to Bentham, the criterion of the right action or the principle of morality consists in the greatest pleasures for the greatest number of people, since Bentham never recognized the qualitative differences among pleasures. Since pleasure is quantitatively measurable, one is able to calculate the amount of and the extent of pleasures that a human action will produce. This measurement of pleasures is called by Bentham the Hedonistic Calculus: The Hedonistic Calculus consists of seven factors, namely
intensity of the pleasure or pains involved
certainty or uncertainty
propinquity or remoteness
fecundity, the tendency to produce a pleasure to further produce other pleasures and a pain to lad to other pains
extent, the number of persons whom they affect.
