Here are the basics: (2) that there must necessarily be something that thinks; (3) that thinking is an activity and operation on the part of a being that it assumed to be a cause; (4) that there is an "ego" (meaning that there is such a thing as an "I").

In the Cogito argument the existence of I and each of the concepts are presumed because even though I can doubt for example that the external world exists, but I can't doubt that the concept of "external world" exists in my mind as well as all concepts in the Cogito statement, and since all of these are subordinate to my mind I can then deduce my own existence from those perceptions.
