Ceteris Paribus Laws/CPL/Cartwright: not "The other things are assumed to be the same", but "the other things are assumed to be correct" - different version: as "substitute": laws that are not quite right, but fulfill the same function - then "cp" is a modifier - then they do not apply to quite as many cases - CPL: and these are wrong! Unknown laws cannot be a reason to say E.g. the angle is so and so because it is different in the purely isotropic medium.
Bet on unknown laws.
CPL only describe processes as long as a single cause exists.
