“How wonderful it would be, frankly, if everybody in the world would suddenly lose his sight or forget the existence of light. Immediately, there would be agreement about form. Everybody would accept the fact that a loaf of bread is a loaf of bread whether triangular or round. The girl a little while ago would have kept her eyes shut and listened to my voice. If she had, perhaps we could have become friendly and I could have taken her to the playground and we could have eaten ice cream together. Just because there was light, she heedlessly thought that a triangular loaf of bread was not bread but a triangle. This thing called light is itself transparent, but it apparently changes into something nontransparent.”
