Universal properties, limits and adjunctions
Products, coproducts, limits and the adjunctions that unify constructions.
lcm(4, 6)
Instead of asking what things are, ask how they map to each other. Category theory finds the same pattern (a product, a limit, an adjunction) recurring across every branch, and gives it one name.
