Interesting Trilemmas
Interesting Trilemmas treats “you can have everything” as a warning that a constraint has been hidden. When three desirable properties conflict, choosing two determines the cost you must accept.
A society can be fair, equal, or free—but, in Steven Pinker’s social trilemma, it cannot fully preserve all three. Reward harder work and wealth diverges; let parents freely pass that wealth to their children and the next generation begins unequal.
E1 R1The third promise hides the bill
Two-way trade-offs are visible: more of one thing usually means less of another. A trilemma is harder to spot because each pair of goals appears achievable. The impossibility emerges only when the third is added.
The familiar fast-cheap-good triangle makes the structure explicit. Fast and cheap sacrifice quality; good and cheap require time; fast and good cost money. The trilemma is not a slogan that nothing can improve. It identifies a binding constraint: unless the system itself changes, maximizing two properties pushes the cost into the third.

Fair, equal, free
A constraint is not a law of nature
A trilemma describes the choices available under the present system. New technology, extra resources, or a redesigned process may move the boundary. The mistake is treating every triangle as permanent—or claiming it has vanished without identifying what changed.
R1Name the sacrificed corner
Tomorrow, when a plan promises three attractive outcomes, draw them as a triangle. For each pair, write the cost imposed on the third, then make the owner of that cost explicit. If nobody can name the sacrifice or the mechanism that removed it, the plan is hiding its bill.
