idea that the laws in England form some sort of system, and that in
France or the United States or Soviet Russia and, indeed, in almost

for example, moral rules and principles, social customs, constitutions
and regulations of voluntary associations, and so on, which are not
laws. Many legal philosophers have tried to justify this common assumption. Various criteria have been offered for demarcating the
limits of law, for testing whether or not a particular standard belongs
to a particular legal system. Various suggestions have been made concerning the importance of the distinction between what is legal and
what is not, and the ways in which, by preserving it, we promote our
understanding of law and society. For it has often been acknowledged
that the distinction is not an easy one to draw in precise terms, and
that any reasonable test would admit the presence of borderline cases.

the majority of cases and partly because it seemed to them crucial for
