I was having a conversation with a friend today about the intricate relationship with two dimensional and three dimensional things in our daily life. We seem to spend much of our time transitioning between these two modes of reality.
We walk through three dimensional rooms to our TV or computer, where we then interact with a 2D view of whatever we are interested in. But often the content on those screens represents something three dimensional, a 3D world much like the one we just walked through.
Yet in that screen-bound 3D world we see people reading books, looking through papers, watching screens, and otherwise focusing their attention on 2D things. And so it goes, an infinite succession of nesting dolls.
I guess this all makes sense. We inhabit these three dimensional bodies, and yet all we see with our eyes at any moment is essentially a 2D view of the world. So of course we intertwine these two types of realities on such a fundamental level that we hardly even notice that we are doing it.
