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") 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.
In modern times, liberal arts education is a term that can be interpreted in different ways. It can refer to academic subjects such as literature, philosophy, mathematics, and social and physical sciences, 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.
Rooted in the basic curriculum – the enkuklios paideia or "education in a circle" – of late Classical and Hellenistic Greece, the "liberal arts" or "liberal pursuits" (Latin liberalia studia) were already so called in formal education during the Roman Empire; Seneca the Younger discusses liberal arts in education from a critical Stoic point of view in Moral Epistle 88. The exact classification of the liberal arts varied however in Roman times, and it was only after Martianus Capella in the 5th century AD influentially brought the seven liberal arts as bridesmaids to the Marriage of Mercury and Philology, that they took on canonical form.
