Today, across the dailies
Three daily surfaces I run, each on its own audience — a word and where it came from, a U.S. patent worth looking at, a paradox worth re-reading. Three independent rotations; this page is the editorial home that pulls today's pick from each. The dailies live where their readers find them; this is where they sit together.
rehearse
To rehearse is to go over a thing again before its real performance — to run the lines, walk the blocking, practice the speech. The word is, at the root, agricultural: Old French <em>rehercier</em>, "to harrow again," from <em>herce</em>, a harrow — the spiked frame dragged across a plowed field to break the clods and even the soil. To rehearse is to drag the rake back over ground you have already worked: a second pass over the same earth. The funeral <em>hearse</em> is the harrow's sibling — it began as a harrow-shaped frame of spikes set with candles over a coffin. And the farm implement called a <em>harrow</em> in English is, despite being the same tool, a false friend: a separate Germanic word. The word for practice is a word for re-tilling — working the same field a second time until it lies right.
Design for a Bottle (Coca-Cola contour)
A design patent — protecting only ornamental appearance, not function — for the Coca-Cola contour bottle. The Coca-Cola Company in 1915 had a problem: imitators. They asked their bottle suppliers for a shape so distinctive it could be 'recognized in the dark, or by feel, even if shattered on the ground.' Earl Dean at Root Glass Company in Terre Haute, Indiana sketched the curves based on (he thought) the cocoa pod — though he had actually been looking at an encyclopedia entry for the cocoa bean. The bottle is one of the few packaging designs ever to be granted trademark protection on shape alone, in 1977.
The Ship of Theseus
The Athenians preserved Theseus’s ship by replacing rotting planks with new ones. After every plank had been replaced, was it still the same ship?
Hobbes added the harder version: someone collects the discarded planks and rebuilds the original. Now there are two ships, each with a claim. The puzzle isn’t really about ships — it’s about what makes any persisting object (a city, a forest, a person) the same thing across time. Modern philosophers split into psychological-continuity, physical-continuity, narrative or social-recognition theories, and the four-dimensionalist view that the ship is a sum of temporal parts and the question dissolves. None of the answers feels obviously right when you try to apply it to yourself. The cells in your body have all turned over many times. So has the language you think in.
