  Some other criticisms of motivational hedonism can be quickly rebutted. One such criticism is that we are often motivated by things that in fact give us neither pleasure nor the best available pleasure-displeasure balance, such as when we step under a shower that we take to be suitably warm but find instead to be scalding hot. Another is that the idea of maximal pleasure, or of the best feasible pleasure-displeasure balance, assumes a common measure that cannot be had. A third criticism is that not every pleasure in prospect motivates us. Hedonists can reply: first, that one is always and only motivated by what one thinks to be one's maximal or sufficient pleasure or pleasure-displeasure balance; second, that this is possible even if the idea of pleasure maximization in such settings does not ultimately make sense; and third, that hedonism does not imply that one is motivated by every pleasure prospect.
