For which reason it is wrong to say that Pleasure is “a sensible process of production.” For “process etc.” should be substituted “active working of the natural state,” for “sensible” “unimpeded.” The reason of its being thought to be a “process etc.” is that it is good in the highest sense: people confusing “active working” and “process,” whereas they really are distinct.
Next, as to the argument that there are bad Pleasures because some things which are pleasant are also hurtful to health, it is the same as saying that some healthful things are bad for “business.” In this sense, of course, both may be said to be bad, but then this does not make them out to be bad simpliciter: the exercise of the pure Intellect sometimes hurts a man’s health: but what hinders Practical Wisdom or any state whatever is, not the Pleasure peculiar to, but some Pleasure foreign to it: the Pleasures arising from the exercise of the pure Intellect or from learning only promote each.
