This Short Introduction looks at judging and reasoning from three perspectives: what legal reasoning has been; what legal reasoning is from the view of judges and jurists themselves (the internal view); and what legal reasoning is from the view of a social scientist epistemologist or humanities specialist (the external view). Combining cases and materials with original text, this unique, concise format is designed for students who are starting out on their law programmes, as well as for students and researchers who would like to examine judging and legal reasoning in more depth.
