Mankiw and ghosts.

Indeed, ideas do not "exist," nor does wealth, no does the "mind,"  nor do emotions, nor does math. How much of our lives are driven by nouns that do not exist in any material way?

Plato discovered Virtual Reality, and the epistemological message for today is that we all live in a mostly invisible Virtual Reality. It's no wonder we're all half-insane because our minds mess us up, and thus it's no wonder we love things we can touch like wood, metal, books, pretty girls (or boys, as the case may be), and plants.

Still, invisible things are often the most important and powerful. Like God.
