The best app to learn philosophy, by arguing with it

By the edgi team

edgi is the best app to learn philosophy, because philosophy is something you do, and edgi lets you do it. Its free Lessons take about 60 seconds, more than 2,500 of them are philosophy, and the best put you inside a thought experiment that you then have to answer yourself. Fathom covers the big thinkers in order, and Roots sends a quiet lesson every day.

We make edgi, and we built it to be the most fun way to learn philosophy, which mostly means arguing with it.

Why edgi is the best philosophy app

Read that John Searle argued a computer can follow a program without understanding anything, and you'll forget it by lunch. Sit in his room instead. Chinese symbols come in, you pass answers back by following a rulebook, and every answer is perfect, though you don't know a word of Chinese. Now you owe Searle a reply. With a chatbot on every phone, it's also one of the most current arguments in philosophy.

That's the Chinese room, and on edgi it's a Lesson you play. The last part hands the argument back to you as a question. It's one of 50 philosophy Lessons among edgi's 318 interactive ones, the longer kind, which run a few minutes: the Chinese room, the Turing test, Laplace's demon, and whether a choice can be fully caused and still be free.

The Stoics get a run of their own: Zeno first, then Seneca, then Epictetus. After them comes the emperor who feared power would soak into him like purple dye. He plays right here:

60-second Lesson

Marcus Aurelius

The most powerful man alive feared power would soak into him like purple dye, so he stripped its shine.

Finish it and Marcus is yours, a card that lights up on your Map beside Stoicism and the Meditations. Seneca and Commodus are neighbors too. Each one is another Lesson and another card, and a streak counts the days you keep going.

Philosophy is where edgi's Map gets strange. Its ideas lead most often into psychology and religion. Determinism sits one step from the butterfly effect and one step from moral luck, the puzzle of blaming people for what chance decided. Our rabbit-hole data has more crossings like these.
