 Book VII offers a brief account of what pleasure is and is not. It is not a process but an unimpeded activity of a natural state (1153a7–17). Aristotle does not elaborate on what a natural state is, but he obviously has in mind the healthy condition of the body, especially its sense faculties, and the virtuous condition of the soul. Little is said about what it is for an activity to be unimpeded, but Aristotle does remind us that virtuous activity is impeded by the absence of a sufficient supply of external goods (1153b17–19). One might object that people who are sick or who have moral deficiencies can experience pleasure, even though Aristotle does not take them to be in a natural state. He has two strategies for responding. First, when a sick person experiences some degree of pleasure as he is being restored to health, the pleasure he is feeling is caused by the fact that he is no longer completely ill. Some small part of him is in a natural state and is acting without impediment (1152b35–6). Second, Aristotle is willing to say that what seems pleasant to some people may in fact not be pleasant (1152b31–2), just as what tastes bitter to an unhealthy palate may not be bitter. To call something a pleasure is not only to report a state of mind but also to endorse it to others. Aristotle’s analysis of the nature of pleasure is not meant to apply to every case in which something seems pleasant to someone, but only to activities that really are pleasures. All of these are unimpeded activities of a natural state.
