“In fact, there are two standard ways to compare different pleasures with each other – the ordinal and the cardinal.

The cardinal criterion, on the other hand, tells us how much more, or less, pleasurable one activity is compared with the other; for instance, does someone find reading a book twice as pleasurable as drinking a Coke?”
