Holmes next introduces his most important and influential argument, the "bad-man" theory of law: "f we take the view of our friend the bad man we shall find that he does not care two straws" about either the morality or the logic of the law. For the bad man, "legal duty" signifies only "a prophecy that if he does certain things he will be subjected to disagreeable consequences by way of imprisonment or compulsory payment". The bad man cares nothing for legal theorizing and concerns himself only with practical consequences. In the spirit of pragmatism, Holmes suggests that this is a useful way of laying bare the true meaning of legal concepts.
