When the act is most perfect, the pleasure accompanying it is also the most perfect; and this pleasure puts the finishing consummation to the act.

The pleasure is not a pre-existing acquirement now brought into exercise, but an accessory end implicated with the act, like the fresh look which belongs to the organism just matured.

It is a sure adjunct, so long as subject and object are in good condition.

But continuity of pleasure, as well as of the other exercises, is impossible.

Life is itself an exercise much diversified, and each man follows the diversity that is suitable to his own inclination--music, study, &c.
