This is a famous quote from the Realist School of Jurisprudence.
Oliver Wendell Holmes Jr.
, a prominent American jurist and a key figure in legal realism, proposed this definition in his influential essay "The Path of the Law.
" He argued that law should not be seen as a set of abstract rules, but as a prediction of what judges will actually decide in a particular case.
He suggested looking at law from the perspective of a "bad man" who only cares about the practical consequences of his actions, i.
e.
, the "prophecies" of what the courts will do.
