I say 'mind' or 'a mind' in order not to beg any questions.
Later on I will try and bring out the significance of this difference, but let
me just point to a possible parallel:
There is a distinction between water and something that is made up of water, a lake say, or a puddle. Pointing to a stretch of water, I could say: there is water. Or I may say: there is a lake.

What does the Cogito point to, mind, or something made up of mind?
Remember we noticed the argument earlier that the Cogito showed that there
is thinking but not that there is something doing the thinking.
[link to earlier lecture]
The point I am making now sounds related but is different.
It is that the Cogito shows the existence of mind or a mind - something made
up of mind - without distinguishing between these two.
