For centuries, philosophers believed that all creation was shaped by Nature under the guiding hand of the Divine. The design of things held clues to hidden connections. A plant that looked like an eye might treat diseases of the eye. We know better today, yet when I find a stone with a perfectly-shaped heart embedded in it, I pick it up. This idea of the heart as the center of romance is itself a holdover from ancient times. But even as my head says it’s just a stone, well, my heart says something different. I listen and pocket the stone.
