Full Idea
If anyone thinks pleasure alone is the good, it seems to me enough to ask whether, of two states of the universe holding equal amounts of pleasure, we should really think no better of one in with virtuous dispositions and actions than of its opposite.
Gist of Idea
No one thinks it doesn't matter whether pleasure is virtuously or viciously acquired

A Reaction
An important technique of argument, analagous to scientific experiment. Hold the variable which is considered to be uniquely vital constant, and see if anyone cares if some other variable changes. It is a good argument.
