As then the Workings are different so are their Pleasures; now Sight differs from Touch in purity, and Hearing and Smelling from Taste; therefore, in like manner, do their Pleasures; and again, Intellectual Pleasures from these Sensual, and the different kinds both of Intellectual and Sensual from one another.
It is thought, moreover, that each animal has a Pleasure proper to itself, as it has a proper Work; that Pleasure of course which is attendant on the Working. And the soundness of this will appear upon particular inspection: for horse, dog, and man have different Pleasures; as Heraclitus says, an ass would sooner have hay than gold; in other words, provender is pleasanter to asses than gold. So then the Pleasures of animals specifically different are also specifically different, but those of the same, we may reasonably suppose, are without difference.
Yet in the case of human creatures they differ not a little: for the very same things please some and pain others: and what are painful and hateful to some are pleasant to and liked by others. The same is the case with sweet things: the same will not seem so to the man in a fever as to him who is in health: nor will the invalid and the person in robust health have the same notion of warmth. The same is the case with other things also.
Now in all such cases that is held to be which impresses the good man with the notion of being such and such; and if this is a second maxim (as it is usually held to be), and Virtue, that is, the Good man, in that he is such, is the measure of everything, then those must be real Pleasures which gave him the impression of being so and those things pleasant in which he takes Pleasure. Nor is it at all astonishing that what are to him unpleasant should give another person the impression of being pleasant, for men are liable to many corruptions and marrings; and the things in question are not pleasant really, only to these particular persons, and to them only as being thus disposed.
Well of course, you may say, it is obvious that we must assert those which are confessedly disgraceful to be real Pleasures, except to depraved tastes: but of those which are thought to be good what kind, or which, must we say is The Pleasure of Man? is not the answer plain from considering the Workings, because the Pleasures follow upon these?
If then there be one or several Workings which belong to the perfect and blessed man, the Pleasures which perfect these Workings must be said to be specially and properly The Pleasures of Man; and all the rest in a secondary sense, and in various degrees according as the Workings are related to those highest and best ones.
Chapter V.
Now that we have spoken about the Excellences of both kinds, and Friendship in its varieties, and Pleasures, it remains to sketch out Happiness, since we assume that to be the one End of all human things: and we shall save time and trouble by recapitulating what was stated before.
Well then, we said that it is not a State merely; because, if it were, it might belong to one who slept all his life through and merely vegetated, or to one who fell into very great calamities: and so, if these possibilities displease us and we would rather put it into the rank of some kind of Working (as was also said before), and Workings are of different kinds (some being necessary and choice-worthy with a view to other things, while others are so in themselves), it is plain we must rank Happiness among those choice-worthy for their own sakes and not among those which are so with a view to something further: because Happiness has no lack of anything but is self-sufficient.
By choice-worthy in themselves are meant those from which nothing is sought beyond the act of Working: and of this kind are thought to be the actions according to Virtue, because doing what is noble and excellent is one of those things which are choice-worthy for their own sake alone.
