To overcome this difficulty, Bentham proposed the hedonic calculus. The hedonic calculus lists seven features of pleasure to which attention must be paid in order to assess how great it is: intensity, duration, certainty, propinquity, fecundity, purity, and extent.

Abstract: A modified hedonistic calculus is sketched along the lines first proposed by Bentham and Mill. The major problem encountered is the quantification ... The next two variables (fecundity and purity) are properties of the event or action produced by the pleasure or pain-—not properties of the pleasure or pain, itself.

For an act to predict future acts, Bentham used two additional circumstances: 5) its fecundity and 6) its purity. In order for Bentham’s hedonistic calculus to predict future behaviors, the measurements must be valid, reliable, and agree with a known standard.

We can only guess at the specific algebra Bentham used to compare these variables and he left no note of how to quantify, for example, intensity of pleasure, but in Bentham’s day he envisioned his hedonistic calculus used for many decisions, including calculating jail sentences: given a certain crime,
