 How do we decide what goes on the list? All we can work on is the deliverance of reflective judgement—intuition, if you like. But one should not conclude from this that objective list theorists are, because they are intuitionist, less satisfactory than the other two theories. For those theories too can be based only on reflective judgement. Nor should one think that intuitionism rules out argument. Argument is one way to bring people to see the truth. Further, we should remember that intuitions can be mistaken. Indeed, as suggested above, this is the strongest line of defence available to hedonists: to attempt to undermine the evidential weight of many of our natural beliefs about what is good for people.
