The experience machine challenges hedonistic theories of well-being.
IDEA
Treats pleasure and the absence of pain as central to well-being.

Welfare hedonism holds that pleasure and pain determine how well a life goes for its subject. It is distinct from the psychological claim that people always seek pleasure and from a moral theory about what everyone ought to do. Different versions understand pleasure as sensation, attitude, or a broader experiential condition.
A claim about welfare differs from a claim about motivation or moral obligation. Someone can think pleasure makes a life better without believing that every action is motivated by pleasure or that personal enjoyment excuses harming others. Versions of welfare hedonism also disagree about the nature of pleasure. Attitudes, sensations, and complex experiences need not fit one simple picture. Clarifying the claim prevents an argument against selfishness from being mistaken for an argument against an experiential account of benefit.
Imagine an enjoyable achievement based on a false belief, then compare a real achievement that feels equally enjoyable. If the second improves your life more, explain what reality adds beyond experience. Nozick’s machine intensifies this comparison across an entire life.
A common objection is that friendship, truth, or agency matter independently of felt quality. Hedonists can question the objection or refine what counts as pleasure. The theory also needs an account of mixed experiences, duration, and comparison; ordinary enjoyment is too varied to function as an unexplained single scale.
Compare the enjoyment of a real friendship with an equally pleasant belief in a friendship that does not exist. If you think the real relationship makes life better, ask whether its benefit is entirely explained by experience. A hedonist can challenge that judgment or reinterpret the relevant pleasure, but must explain the difference. The case also separates welfare from other values: something may matter to another person or be morally significant without increasing the subject’s own well-being.
Would perfect pleasure compensate for a life of only simulated relationships?
