Hey,

Are you familiar with Descartes and his meditations on first philosophy? So do you remember where he goes into how people come to know things they've never had access to, like perfect beauty? So do you remember his argument about not being able to know a thing from the negation of that thing?

If you're familiar with this argument can you break down why you can't come to know a thing from the absence of that thing? I remember understanding this when I first read the book but now that I'm thinking about it years later I don't seem to have the argument lined up in my mind. Can you help? I did a quick Google search and I don't see any exact references and explanations of this line I find interesting.

Thanks in advance.
