Metaphysics

⚖The case for it

The book that gave a whole branch of philosophy its name (literally 'after the physics'). Aristotle asks what it means for something to exist, what causes are, what substance is, what the unmoved mover might be. Dense, systematic, occasionally maddening. But this is where ontology begins. If you've ever asked 'What is real?' you're doing Aristotle's homework.

✕The case against

Nobody wrote this book; editors stitched it from lecture notes after Aristotle died, and it shows. Arguments break off, repeat, and contradict across fourteen books, an entire section catalogs other people's errors, and the unmoved mover rests on celestial spheres astronomy retired centuries ago. Philosophy's foundation document reads like the binder of a brilliant professor who never cleaned it out.
