“we have measured the value of the world with categories that refer to a purely fabricated world.” A fabricated world? Yes, the world as a superstructure, the world as a spirit, weightless and abstract, of the same material with which thoughts are woven, and through which therefore they can move unhindered. A world that after three hundred years of natural science is left without mysteries. Everything is explained, everything is understood, everything lies within humanity’s horizons of comprehension, from the biggest, the universe, whose oldest observable light, the farthest boundary of the cosmos, dates from its birth fifteen billion years ago, to the smallest, the protons and neutrons and mesons of the atom.”
