  The cognitive scientist Donald Hoffman argues that we don't perceive reality:
spacetime, objects, colors, sounds, tastes, and so forth, are all merely an
interface that we evolved to track evolutionary fitness rather than to perceive
truths about external reality. In this paper, I expound on his argument, then I
extend it, primarily, by looking at key ideas in physics that are quite germane
to it. Among the topics in physics that I discuss are black holes, the
holographic principle, string theory, duality, quantum gravity, and special
relativity. I discuss these ideas from physics with an eye to their relevance
for Hoffman's view.
