Hedonism is the view that pleasure/happiness is the only intrinsic good. This means that the only thing that is good "in-and-of-itself" is pleasure/happiness. Other things might be instrumentally valuable--that is, valuable as instruments or tools to get other things. Examples of instrumentally valuable things include money and cars. Money is good for buying things that one wants and cars are good for traveling from one place to another. But they don't have intrinsic value. It's not as if money is good for its own sake. It's only good in order to acquire goods/services.
I'm curious what you think about Hedonism. Is there anything else that is intrinsically valuable besides pleasure/happiness?
It's worth mentioning that some things might be both intrinsically valuable and instrumentally valuable [e.g., one's health or the beauty of a piece of art (?)]. My intuitions about these examples aren't clear. Are there examples that you find puzzling? Perhaps a discussion of the puzzling cases will shed some light on the debate over whether Hedonism is true or false.
