1. descartes argues that our minds are nonphysi-
cal spirits, since i can imagine existing without
a body, but i cannot imagine that i do not think.
leibniz criticized descartes as follows: "some-
one who thinks that the soul is corporeal will
admit that you can doubt (as long as you are
ignorant of the nature of the soul) whether any.
thing corporeal exists or does not exist. and as
you nevertheless see clearly that your soul
exists, he will admit that this one thing follows:
that you can still doubt whether the soul is cor-
poreal. but no amount of torture can extort any
thing more from this argument." what is
leibniz's point, and is he correct?
