 The famous intuition of the proposition, “I am, I exist” in Meditations II is discovered by means of enumeration3: the proposition “I am, I exist”, cannot be placed into any of the classes of dubitable opinions enumerated in Meditations I because not even the most malicious demon “can bring it about that I am nothing so long as I think that I am something” (AT 7: 25, CSM 2: 17). Here, intuition comes after enumeration3 has prepared the way.
