This article unpacks the concept of the rule of law by distinguishing five distinct meanings of the term. These are: (1) the rule of practical wisdom, (2) the rule of the law, (3) rule by law, (4) the rule of law as a principle of constitutionalism, and (5) the rule of law as a power-building technique. It suggests that unless the particular meaning being used is clarified, discussion of the concept is likely to generate more heat than light.
