What in the world is intrinsically good — good in itself even if it has no other effects? Over the millennia, people have offered many answers: joy, justice, equality, accomplishment, loving god, wisdom, and plenty more.

The question is a classic that makes for great dorm-room philosophy discussion. But it's hardly just of academic interest. The issue of what (if anything) is intrinsically valuable bears on every action we take, whether we’re looking to improve our own lives, or to help others. The wrong answer might lead us to the wrong project and render our efforts to improve the world entirely ineffective.

Today's guest, Sharon Hewitt Rawlette — philosopher and author of The Feeling of Value: Moral Realism Grounded in Phenomenal Consciousness — wants to resuscitate an answer to this question that is as old as philosophy itself.

That idea, in a nutshell, is that there is only one thing of true intrinsic value: positive feelings and sensations. And similarly, there is only one thing that is intrinsically of negative value: suffering, pain, and other unpleasant sensations.

Lots of other things are valuable too: friendship, fairness, loyalty, integrity, wealth, patience, houses, and so on. But they are only instrumentally valuable — that is to say, they’re valuable as means to the end of ensuring that all conscious beings experience more pleasure and other positive sensations, and less suffering.

As Sharon notes, from Athens in 400 BC to Britain in 1850, the idea that only subjective experiences can be good or bad in themselves -- a position known as 'philosophical hedonism' -- has been one of the most enduringly popular ideas in ethics.

And few will be taken aback by the notion that, all else equal, more pleasure is good and less suffering is bad. But can they really be the only intrinsically valuable things?

Over the 20th century, philosophical hedonism became increasingly controversial in the face of some seemingly very counterintuitive implications. For this reason the famous philosopher of mind Thomas Nagel called The Feeling of Value "a radical and important philosophical contribution."

In today's interview, Sharon explains the case for a theory of value grounded in subjective experiences, and why she believes the most popular counterarguments are misguided.

Host Rob Wiblin and Sharon also cover:

• The essential need to disentangle intrinsic, instrumental, and other sorts of value
• Why Sharon’s arguments lead to hedonistic utilitarianism rather than hedonistic egoism (in which we only care about our own feelings)
• How do people react to the 'experience machine' thought experiment when surveyed?
• Why hedonism recommends often thinking and acting as though it were false
• Whether it's crazy to think that relationships are only useful because of their effects on our subjective experiences
• Whether it will ever be possible to eliminate pain, and whether doing so would be desirable
• If we didn't have positive or negative experiences, whether that would cause us to simply never talk about goodness and badness
• Whether the plausibility of hedonism is affected by our theory of mind
• And plenty more
