In all of our discussions about the Milesians’ project to explain the fundamental STUFF of the universe, it never struck me that we could ever be trying to speculate about things we haven’t seen yet. Traveling through walls by moving fast enough… dinosaur theme parks… oh yeah, and lightsabers. However, this does bring up something not necessarily emphasized in the study of ancient natural philosophy: how the explanatory models of the universe, developed by Anaximander, Anaximenes, Heraclitus, Aristotle, etc., were sometimes used to predict and describe extrasensory phenomena—things we couldn’t possibly witness on our own. There have been beautiful descriptions of the celestial orbs out in the aether (Scipio’s Dream), of the endlessly complex system of prime movers encompassing the universe in their thrumming harmony (Plato’s Timaeus), the enterprise speculative philosophy was prominent enough to become the target of lampooning (Lucian’s True History, audio). Regardless of whether our predictions are accurate, whatever that may mean, it’s a comforting thought to think that if this era is ever studied with an eye to our aspirations, our dream will be Lucas’s, our ethereal orbs will be Jurassic Park.
