The liberal arts (Latin: artes liberales) are those subjects or skills that in classical antiquity were considered essential for a free person (Latin: liberalis, "worthy of a free person")[1] to know in order to take an active part in civic life, something that (for Ancient Greece) included participating in public debate, defending oneself in court, serving on juries, and most importantly, military service. Grammar, logic, and rhetoric were the core liberal arts, while arithmetic, geometry, the theory of music, and astronomy also played a (somewhat lesser) part in education.[2] Liberal arts education can refer to academic subjects such as literature, philosophy, mathematics, and social and physical sciences,[3] or it can also refer to overall studies in a liberal arts degree program. For example, Harvard University offers a Bachelor of Arts degree, which covers the social and natural sciences as well as the humanities. For both interpretations, the term generally refers to matters not relating to the professional, vocational, or technical curriculum.
The practice of making law around laws so one doesn't get close to sin is known as "Hedging The Law".
A hedge in this sense is to be likened to building a wall around another wall. So, the purpose of hedging the law is to hinder people from getting close to breaking the law. This hedging of the law was seen among the Jews.
