Long ago, ice cube trays were made of metal. They came with a contraption in the middle that had an 8-inch lever and a dozen or so flaps, which divided the tray into compartments. After the water in the tray froze solid, you pulled the lever — with about the same force you would need switching track in a railyard — and the flaps cracked the ice. Mostly regular-shaped blocks slid out of the tray. Logic at times may seem cold, compartmentalizing, and forced.
Metaphor is a warmer form of rhetoric: intuitive rather than inevitable. Metaphor brings you to “I see” in an “aha!” moment, where logic takes you from point A to B step by step by step. Anyone struggling to pass Calculus will agree the path to clarity by rigor is full of hardship.
Metaphor IS goofy. Calling snow a blanket, a river a snake, or the world a stage… How can we hope to arrive at truth by comparisons that are literally untrue?
Paradox is indeed a tough nut to crack.
