Full Idea
While it can be intelligently asked whether the pleasant or beautiful has value, it cannot be intelligently asked whether the good has value, since the good is just to be valuable.
Gist of Idea
We can ask of pleasure or beauty whether they are valuable, but not of goodness

A Reaction
It is simply tautological that goodness has value, and that valuable things are good. But an assassin might 'value' a 'good' way of killing someone, or an instrument of torture. We might say "He values x, but x is bad". Still, he must think x is good.
