High Quality Content by WIKIPEDIA articles! Preference utilitarianism is one of the most popular forms of utilitarianism in contemporary philosophy. Unlike classical utilitarianism, which defines right actions as those that maximize pleasure and minimize pain, preference utilitarianism promotes actions that fulfill the interests (preferences) of those beings involved. The beings may be rational, that is to say, their interests may be carefully selected based on future projections, but this is not compulsory; here, the definition of "party" extends to all sentient beings, even those living solely in the present. Since what is good and right depends solely on individual preferences, there can be nothing that is in itself good or bad: for preference utilitarians, the source of both morality and ethics in general is subjective preference. Preference utilitarianism therefore can be distinguished by its acknowledgement that every person`s experience of satisfaction is unique.
