Note that the problem at Charm. 170d-171a is not, “The medical man knows nothing about medicine,” as it is usually cited, but, “The medical man knows nothing about medicine either.” Neither the doctor nor the epistemologist knows anything about medicine. Everything now depends on whether one rejects the dilemma for the sake of the apparent givenness of the middle term, or recognizes this middle as a pure imaginary, its function in constituting society notwithstanding.
