The principal modern schools of
jurisprudence are the natural-law school, the
analytical school, the historical school, the
comparative school, and the socio-logical
school. The first three differ mainly in their
views of the nature and origin of law and its
relation to ethics. The philosophical school is the
oldest (William 0. Douglas, Associate Justice of
the U.S. Supreme Court).
