Skepticism

I know only my experience, so I have to imagine yours
A traditional skeptical argument
     Not skepticism of lst Meditation, but skepticism about other minds

How can I know
     1 that you have similar experience
     2 that you have any experience

Argument for 1.
     Maybe your experience of seeing red is like mine of seeing blue
and vice versa
How could I ever know, if you identified colors correctly

One reply: if there is no such observable difference, why think this is even imaginable
     Really are asking; imagine you could look into my mind and see my experience
     but that is impossible

A real objection to Descartes he encourages this impossible way of thinking

A fuller theory of color might destroy this analysis. Talking, say, about color relationships
     I don't take up that point

Argument for 2:
Why think that you have any experience?
     You pick out blue, red objects and that skill we can talk about

You could be an automaton for all I know
          If we are rejecting Descartes's view of reason
     I can only observe your behavior, not know that you are conscious
