Experience machine

The Experience machine is a thought experiment created by the libertarian philosopher Robert Nozick. It was an argument against hedonism.

Thought Experiment

Nozick said that if it were possible for anyone to plug himself into a machine that could create an illusion of any experience the person chose based on what would give that person the most pleasure then almost everyone would refuse to plug into it. Nozick used this to prove that there are more important things than pleasure.
