Is Descartes' Cogito argument indubitably sound? Descartes tells us, basically:
- I think.
- Therefore, I am.
Instead of providing us with an argument against scepticism, Descartes shows us by example how we should argue our way out. In fact, there is no argument that he could give that we could use. Suppose Descartes said:
- You think.
- Therefore, you are.
I suppose this is why Descartes called these thoughts meditations.
