Reality reduces to some equation/s, maybe with the eloquence of E=MC^2 or an Eulerian masterpiece. But Hawking wondered, “What is it that breathes fire into the equations and makes a universe for them to describe?.” One imagines a space-time matrix containing egos. These: space, time, ego; cannot be imagined away—a reality base?

I side with Kant: it depends on the box one is in; unless, one can escape or look over the edge thereon. Maybe 42.
