Capital, debt, and alchemy
The ancient alchemists wanted to transmute corrosion-prone base metals into permanent, non-corruptible, time-resistant gold. Modern economic alchemists want to convert spoiling, rusting, and depleting wealth into a magic substance better than gold — not only does it resist corrosion, but it grows — by some mysterious principle the alchemists referred to as the “vegetative property of metals.” The modern alchemical philosopher’s stone, known as “capital” or “debt,” is not only free from the ravages of time and entropy, but embodies the alchemists’ long-sought-for principle of vegetative growth of metals. But once we replace alchemy with chemistry we find that the idea that future people can live off the interest of their mutual indebtedness is just another perpetual motion delusion.
