It is hard for a flat thing to understand a round one.

I would like to make something that is real in itself that does not remind anyone of any other things, and that does not have to be explained like the letter A, for instance.

How do you feel about a person when you're talking over the phone? If you know them, or if you don't know them, do you get something, do you put that into words of your own, from what they say, or from what you think? Or if it were music over the radio, have you ever tried to think how it would look?

It is the form the idea takes in the imagination rather than the form as it exists outside.
