To my mind, one of the most intriguing of the ancient Greek philosophers is the second of the great Eleatics, Zeno of Elea. But ... does he still matter? C ome, let us reason together. If the fastest of warriors, Achilles, can not catch up with a tortoise, then something is of course very wrong with the way we understand our life in the world. That is of course Zeno's point. He was defending an Eleatic monism, a sort of Hellenic gaslighting that told the world nothing is as it seems, so he was committed to saying that since the apparent world is illusory, something crazy must be true.

The importance of sprockets in the day-to-day life of that cartoon's world is a running gag. Geor...
