Alright, I just HAD to create an account to point this out, since it appears no one has yet. "Close one eye, step to the side" is basically a very compact description of the method of parallax. (Hmmm...where have I heard that term before?)
In this method, you can measure how far away a horizontal object is by closing one eye and changing your viewpoint in a perpendicular direction to the object. By measuring the angle of the object's apparent displacement relative to some background, you can determine how far away from you it is.
What the metaphorical meaning of this is, I have no idea. Possibly it has to do with attempting to understand ideas that are difficult to see from our mortal perspective. But Tommy seems to be using a lot of terminology related to optics recently (Specular Reflection, Mirrors, Parallax, etc.), so remember your physics, people!
