While I somewhat disagree with the point made in the following passage (I think emotions are better treated as signals than outcomes), I submit it is a good sample of his provocative writing style.
Nothing more than feelings? What could be more important than feelings? Sure, war and peace may come to mind, but are war and peace important for any reason other than the feelings they produce? If war didn't cause pain and anguish, if peace didn't provide for delights both transcendental and carnal, would either of them matter to us at all? War, peace, art, money, marriage, birth, death, disease, religion -- these are just a few of the Really Big Topics over which oceans of blood and ink have been spilled, but they are really big topics for one reason alone: Each is a powerful source of human emotion. If they didn't make us feel uplifted, desperate, thankful, and hopeless, we would keep all that ink and blood to ourselves.
As Plato asked, "Are these things good for any other reason except that they end in pleasure, and get rid of and avert pain? Are you looking to any other standard but pleasure and pain when you call them good?" Indeed, feelings don't just matter -- they are what mattering means. We would expect any creature that feels pain when burned and pleasure when fed to call burning and eating bad and good, respectively, just as we would expect an asbestos creature with no digestive tract to find such designations arbitrary.
Moral philosophers have tried for centuries to find some other way to define good and bad, but none has ever convinced the rest (or me). We cannot say that something is good unless we can say what it is good for, and if we examine all the many objects and experiences that our species calls good and ask what they are good for, the answer is clear: By and large, they are good for making us feel happy.
