  Consider the following unification argument for hedonism about value: the case for the value of pleasure is stronger than the case for the value of any non-pleasure; the more unified the theory of value the better it is; unification around the strongest case is better than unification around any other case; therefore: hedonism is the best theory of value. This argument has weaknesses. Its first premise is not obviously true and needs further argument. In addition, the further argument that it still needs is in effect a separate argument for hedonism over its rivals, so this unification argument is not self-standing. Its second premise is also ambiguous between the claim that a theory of value is in one respect better if it is more unified, and the claim that it is all-things-considered better if it is more unified. Plausibility requires the first interpretation, but the unification argument requires the second interpretation. In short, there are significant problems with this unification argument for ethical hedonism.
