Descartes, Locke, and Leibniz each had a theory about what happens to the mind during sleep. Explain the theoretical differences, as well as the similarities (there is a point of agreement between Descartes and Locke, and between Descartes and Leibniz). Which theory do you find most convincing, and why? Remember to discuss Locke’s response to Leibniz’s theory: The notion of unconscious thinking during sleep, Locke claimed, has the absurd result of creating two persons in one body (see Locke’s example of “sleeping Socrates” and “waking Socrates”). Is this a good point against Leibniz?
