13But further (E) it is agreed that pain is bad and to be avoided; for some pain is without qualification bad, and other pain is bad because it is in some respect an impediment to us. Now the contrary of that which is to be avoided, qua something to be avoided and bad, is good. Pleasure, then, is necessarily a good. For the answer of Speusippus, that pleasure is contrary both to pain and to good, as the greater is contrary both to the less and to the equal, is not successful; since he would not say that pleasure is essentially just a species of evil.
Speusippus succeeded Plato as the head of the Academy. He was deeply suspicious of Plato's notions about the Good, and of forms in general; Aristotle, though he differs as well, rejects Speusippus' particular critique.
And (F) if certain pleasures are bad, that does not prevent the chief good from being some pleasure, just as the chief good may be some form of knowledge though certain kinds of knowledge are bad. Perhaps it is even necessary, if each disposition has unimpeded activities, that, whether the activity (if unimpeded) of all our dispositions or that of some one of them is happiness, this should be the thing most worthy of our choice; and this activity is pleasure. Thus the chief good would be some pleasure, though most pleasures might perhaps be bad without qualification.
Theologically later Christian Aristotelians will accept that the chief good lies in contemplation of the divine, which is supposed to maximize pleasure, beauty, and knowledge all at once. The idea that 'some pleasure' could be good even though most pleasures are bad -- so bad that we should push pleasures off like the old men at the gates of Troy looking upon Helen -- is nevertheless surprising.
John Stuart Mill, the Utilitarian, defends a version of this idea himself. Utility is supposed to be the pursuit of pleasure and avoidance of pain; against the charge that this is merely hedonism, he said that the fact that people can't think of higher pleasures says more about them than about pleasure. Perhaps the highest pleasures do include things like contemplation of the divine, which might excel the lower pleasures we have been warned against so sternly.
And for this reason all men think that the happy life is pleasant and weave pleasure into their ideal of happiness-and reasonably too; for no activity is perfect when it is impeded, and happiness is a perfect thing; this is why the happy man needs the goods of the body and external goods, i.e. those of fortune, viz. in order that he may not be impeded in these ways. Those who say that the victim on the rack or the man who falls into great misfortunes is happy if he is good, are, whether they mean to or not, talking nonsense. Now because we need fortune as well as other things, some people think good fortune the same thing as happiness; but it is not that, for even good fortune itself when in excess is an impediment, and perhaps should then be no longer called good fortune; for its limit is fixed by reference to happiness.And indeed the fact that all things, both brutes and men, pursue pleasure is an indication of its being somehow the chief good:
The above section is one of the times that Aristotle talks about fortune and happiness. Happiness is the goal of ethics, we know from Book I. Yet things that we can't control ourselves -- such as whether or not we receive honors from others -- aren't thought worthy of being the goal of ethics because that goal should be something that lies within our power to do or not do.
Finding that Lady Luck (Agatha Tyche) is so involved with our happiness thus ought to make us wonder about happiness as the proper end of ethics. Yet it turns out that fortune's limits are set by our natural capacity for happiness rather than the other way around: so it does, in a way, depend on us and what is internal to us. We are lucky if we get what we need, but not more, for the 'good luck' of winning more ends up being an impediment to us realizing our happiness after all. We have to perfect what is within ourselves, and to hope only for that which allows such internal perfection.
