about the paper
thinking made playable
The daily aporia turns the great thought experiments of philosophy into small interactive machines you can use, rather than essays you merely read. An aporia is the moment a good argument pushes your own intuitions into disagreeing with one another. That moment is the whole point.
None of the 20 experiments tells you what to believe. Each runs on one of three engines: consistency tests mark your true and false answers, then show you where two of them cannot both be reasonable; branching dilemmas walk you through tightening scenarios and name the position your choices commit you to; puzzles pose one hard problem, let you answer, then reveal the argument you did not make.
Every answer stays in your own browser. There are no accounts and no tracking, and the catalogue grows over time. Where a puzzle has more than one good answer, and most do, each side is given its strongest case.
