solvitur ambulando (11. 620)

The paradoxes of ancient Greek philosopher Zeno, as recorded by Aristotle’s Physics, argues motion is illusionary with the dichotomy that a traveler must arrive at the half-way point before reaching the goal, and before getting to the mid-stage, must necessarily travel a quarter and before that an eighth, a sixteenth, a thirty-second, a sixty-fourth and so on. Not finding the sum that all these fractional steps forwards didn’t complete the journey wasn’t Zeno’s objection but rather how to finish an infinite—though infinitesimal—number of tasks. Fellow philosopher and noted Cynic Diogenes, simply got up and left the conversation to demonstrate the contrary after hearing this line of reasoning. Attributed later to Saint Augustine, the Latin phrase “it is solved by walking” from this account, has become a catch-all directing one to answer practical problems with practical rejoiners—to walk it off as the sovereign remedy for every travail.
