Bentham uses the hedonic calculus to measure the total amount of happiness based on seven factors: intensity, duration, certainty or uncertainty, propinquity, fecundity, purity, and extent
Property in any object that tends to produce benefit, advantage, pleasure, good, or happiness, or to prevent the happening of mischief, pain, evil, or unhappiness
The hedonic calculus measures the quantity of happiness by evaluating each possible action in view of factors like intensity, duration, certainty, and extent
Jeremy Bentham: '"When a man attempts to combat the principle of utility, it is with reasons drawn, without his being aware of it, from the very principle itself"'
