Pleasures differ from each other in species: there are good pleasures, _i.e._, those arising from good sources; and bad pleasures, _i.e._, from bad sources.

The pleasure _per se_ is always desirable; but not when it comes from objectionable acts.
The pleasures of each man will vary according to his character; none but a musical man can enjoy the pleasures of music.

No one would consent to remain a child for life, even though he were to have his fill of childish pleasure.
Aristotle sums up the result thus.

Pleasure is not The Good.

Not every mode of pleasure is to be chosen.
