> If I cover your eyes and put a teacup on your open palm so you can't see the colour or feel the size, _what are you holding_? I obviously failed to communicate what I was saying. If you give me a teacup and tell me to imagine I can see it, I have to know what it looks like before I can form that image. This is all just a failure of communication because to me, part of the definition of having an image of something in your mind is that you know what it looks like. Since knowing the colours and shapes are required to form an image, if you don't have those, you don't have an image. Imagining a teacup is possible without imagining you can see a teacup.
