Hedonism

hedonism refers to a family of theories, all of which have in common that pleasure plays a central role in them. Psychological or motivational hedonism claims that human behavior is determined by desires to increase pleasure and to decrease pain. Normative or ethical hedonism, on the other hand, is not about how humans actually act but how humans should act: people should pursue pleasure and avoid pain. Axiological hedonism, which is sometimes treated as a part of ethical hedonism, is the thesis that only pleasure has intrinsic value. Applied to well-being or what is good for someone, it is the thesis that pleasure and suffering are the only components of well-being. These technical definitions of hedonism within philosophy, which are usually seen as respectable schools of thought, have to be distinguished from how the term is used in “everyday language”. In that sense, it has a negative connotation, linked to the egoistic pursuit of short-term gratification by indulging in sensory pleasures without regard for the consequences.
