A textual case can be made on behalf of both formulations being raised in the Meditations. But when I see, or think I see I am not here distinguishing the twoit is simply not possible that I who am now thinking am not something. Finally, a common objection has it that the universality of doubt undermines the method of doubt itself, since, for example, the sceptical hypotheses themselves are so dubious.
