 Through the Defence, Cockburn additionally makes clear that although Locke’s theory of personal identity allows for sci-fi switches such as those described in the “prince and the cobbler” passage (L-N 2.27.15), the “waking and sleeping Socrates” passage (2.27.19), and the “day and night-man” passage (2.27.23), Locke does not think that this is the way things ordinarily go. In other words, in Locke’s view it is not that persons are switching bodies and swapping souls on a regular basis. Rather, Locke is making clear that we should distinguish between the concepts “man”, “body”, “soul”, and “person”. Moreover, the persistence of any person does not always align with the persistence of a human being or soul, as many assume. Making this point is the purpose of those imaginary cases.
