 Aristotle indicates several times in VII.11–14 that merely to say that pleasure is a good does not do it enough justice; he also wants to say that the highest good is a pleasure. Here he is influenced by an idea expressed in the opening line of the Ethics: the good is that at which all things aim. In VII.13, he hints at the idea that all living things imitate the contemplative activity of god (1153b31–2). Plants and non-human animals seek to reproduce themselves because that is their way of participating in an unending series, and this is the closest they can come to the ceaseless thinking of the unmoved mover. Aristotle makes this point in several of his works (see for example De Anima 415a23–b7), and in Ethics X.7–8 he gives a full defense of the idea that the happiest human life resembles the life of a divine being. He conceives of god as a being who continually enjoys a “single and simple pleasure” (1154b26)—the pleasure of pure thought—whereas human beings, because of their complexity, grow weary of whatever they do. He will elaborate on these points in X.8; in VII.11–14, he appeals to his conception of divine activity only in order to defend the thesis that our highest good consists in a certain kind of pleasure. Human happiness does not consist in every kind of pleasure, but it does consist in one kind of pleasure—the pleasure felt by a human being who engages in theoretical activity and thereby imitates the pleasurable thinking of god.
