 Aristotle explains what he has in mind by comparing akrasia to the condition of other people who might be described as knowing in a way, but not in an unqualified way. His examples are people who are asleep, mad, or drunk; he also compares the akratic to a student who has just begun to learn a subject, or an actor on the stage (1147a10–24). All of these people, he says, can utter the very words used by those who have knowledge; but their talk does not prove that they really have knowledge, strictly speaking.
