Picture a hedonist and you probably imagine a wild party and reckless short-term thrills, what philosophers call folk hedonism. But across ancient Greek and Indian texts, evolutionary biology, behavioral economics, and positive psychology, hedonism is a comprehensive framework for understanding human motivation, value, and the biological machinery driving our behavior. This episode strips away the Vegas-weekend stereotype to explore one of philosophy’s most misunderstood ideas.

We walk through the three major branches: psychological hedonism, with Hobbes, Freud’s pleasure and reality principles, and the Darwinian dopamine pathway; axiological hedonism, from Bentham’s felicific calculus to Mill’s higher and lower pleasures, challenged by G.E. Moore’s two worlds and Robert Nozick’s experience machine; and ethical hedonism, split between the egoism of the Charvaka school and Aristippus and the utilitarianism of Peter Singer’s effective altruism. We finish with the paradox of hedonism, the hedonic treadmill, and Epicurus’s answer of ataraxia.

• How psychological hedonism explains altruism, parental sacrifice, and a soldier jumping on a grenade
• Bentham’s calculus of intensity, duration, certainty, and propinquity versus Mill’s claim that it is better to be a human dissatisfied than a pig satisfied
• Why most people refuse to plug into Nozick’s experience machine, and what that reveals about the value of authenticity
• The demandingness and justice objections to utilitarian hedonism
• Welfare economics, positive psychology, animal ethics, and David Pearce’s transhumanist plan to engineer suffering out of existence
