Kitap 10

(It is clear that each of the senses is accompanied by pleasure, since we apply the term pleasant to sights and soundsAs well as to tastes, scents, and contacts, which are more obviously pleasant.; and it is also clear that the pleasure is greatest when the sensory faculty is both in the best condition and acting in relation to the best object; and given excellence in the perceived object and the percipient organ, there will always be pleasure when an object to cause it and a subject to feel it are both present.)

But the pleasure perfects the activity, not as the fixed disposition does, by being already present in the agent, but as a supervening perfection, like the bloom of health in the young and vigorous.
8
So long therefore as both object thought of or perceived, and subject discerning or judging, are such as they should be, there will be pleasure in the activity; since while both the passive and the active parties to a relationship remain the same in themselves and unaltered in their relation to one another, the same result is naturally produced.
