The cookbook gives a detailed description of ingredients and procedures but no proofs for its prescriptions or reasons for its recipes; the proof of the pudding is in the eating. ...

If the world is an aggregate of relatively independent regions, then any assumption of universal laws is false and a demand for universal norms tyrannical : only brute force (or seductive deception) can then bend the different moralities so that they fit the prescriptions of a single ethical system.
