Utilitarian's believe that humans are motivated by the pursuit to maximise happiness and minimise pain, which is called a hedonist view. Utilitarianism is an ethical principle, a philosophical system which takes into account consequences of an action rather than motives, where the happiness of the greatest number should be the result, as it is therefore morally right.
Jeremy Bentham's understanding of the utilitarian principle is called Act Utilitarianism. His approach states that the rightness or wrongness of an individual act is calculated by the amount of happiness that results from the act. His view is also a hedonist view, which proposes that the main good is pleasure, whilst the main evil is pain. He therefore proposed that all humans pursue the maximisation of pleasure and minimisation of pain.
Bentham believed in the greatest good for the greatest number, and believed that quantity (rather than Mills belief in quality) played the main role in deciding whether an act was good or not, as the one providing most pleasure for most people, whilst providing least or no pain, is seen as the best choice by Bentham. To decide the value of happiness created with such act, Bentham would apply the Hedonic calculus, with 7 criteria which help to calculate pain and pleasure generated by the act. Intensity would be applied to see how intense the pleasure or pain is, duration to see how long will the pleasure or pain last, certainty to see what is the probability that the pleasure or pain will occur, propinquity to see of how far off in the future is the pleasure or pain, fecundity to see what is the probability that the pleasure will lead to another pleasure, purity to see what is the probability that the pain will lead to other pain in the future and extent to see
