Let us continue our discussion here about the shape of the cube.
I will explain it further.
You see, the human eye has a certain type of lens–a convex lens–and, therefore, it views the objects through this particular convex lens.
Therefore, the objects we see have a certain shape. In fact, it is what we register as the shape when seen through a convex lens within our eyes.
Now you know that the common housefly, for instance, has a compound eye that has a number of lenses in it. Therefore, when the fly views the same cube that you see, it may view it as a multiple-sided cube, very much like the cubic art of, lets say, Picasso.
This is a multi-dimensional view, and since the fly is born with that kind of a lens, it believes that the cube is actually a multi-dimensional object and not the cube as you see it or I see it.
You can say, ‘I see it this way’. Yes, but the fly sees it differently. I’ll say that, ‘No, no but the fly sees it differently’ and the fly, if it has an intelligence, believes it to be so and, therefore, it sits on all sides. Maybe, it sees multiple images of a hundred cubes stuck together like a cluster. We don’t know.
We have to thus go into the fly’s eye to look. Suppose, the convexity of the lens of your eye was of a different angle, you might see things bigger or smaller. When you look through a microscope, you see very tiny things that you thought didn’t exist. Then, you look through a telescope and you see faraway things closer to you and that’s only when you know they exist.
