Analyze Robert Nozick's 'Experience Machine' thought experiment. Describe the scenario in detail and explain why Nozick believes people would choose reality over a simulated, pleasurable existence. Discuss the implications of this choice for Hedonistic Utilitarianism. Does the desire to 'do' rather than merely 'experience' suggest that pleasure is not the only intrinsic good? Argue for or against the idea that authenticity matters more than happiness.
