 | | The originality of Descartes thinking, therefore, is not so much in expressing the cogito -a feat accomplished by other predecessors, as we have seen- but on using the cogito as demonstrating the most fundamental epistemological principle, that science and mathematics are justified by relying on clarity, distinctiveness, and self-evidence. |
 | | The contention is that this is a syllogistic inference, for it appears to require the extra premise: "Whatever has the property of thinking, exists", and that extra premise must surely have been rejected at an earlier stage of the doubt. |
 | | He claims, for example, that what we are dealing with when we talk of thought, or when we say "I am thinking", is something conceivable from a third-person perspective; namely objective "thought-events" in the former case, and an objective thinker in the latter. |
