Ceteris paribus/BigelowVsCeteris paribus/Qualification/Qualified Act/Exceptions/Bigelow/Pargetter: Variant: "if no other disturbances exist":
1. Problem: what threatens to turn a law into a tautology, which ultimately reads: "Things move so and so, unless they do not."
2. Problem: The scope of a "qualified" law threatens to become so narrow that nothing more falls into that law.
On the other hand, it will be said that a law has no positive authority at all if it is strictly understood. ((s) > N. Cartwright).
Solution/Bigelow/Pargetter: one can solve the riddle by understanding how laws contain modalities.
