““You see... the cave is a metaphor, a tool, an illustration. The formula for its accurate representation is something like S2=(2^2)+1. As I just pasted that formula into this document I realized I do not speak math and therefore could not read that formula aloud were I ever in a situation like a reading where I would need to say the formula out loud. I don't know what S means or what S2 equals, nor do I know how to pronounce that little upside-down V between the pair of 2s. If you speak math, then you know what it means.””
