Question

What is the nature of physical laws?

Answer 1

(1) Physical necessity and possibility and causal relationships are real relations in the world. The claim made by a physical law is the claim made by the corresponding accidental generalization plus the claim that such relations obtain. (2) The apparent difference in meaning between physical laws and accidental generalizations is an illusion. The meaning of the law "All Fs are G's" is exhausted by "(x) (Fx D Gx).
