Following his studies in philosophy and literature, MacCormick won a Snell Exhibition to study in Balliol College, Oxford (1963–65). He studied law, and this chapter explores both his studies – including the teachers who influenced him, such as Donald Harris and Alan Watson – as well as the influence of Richard Hare, whose work on moral reasoning was important for MacCormick. Alongside this, MacCormick participated in student politics at the time: he became President of the Oxford Union and, as he did in Glasgow, participated in the Union’s debates. Following his studies, in the summer of 1965, thanks to a Balliol Pathfinder Scholarship, MacCormick toured the USA, and recorded his observations, especially with relation to race and civil rights issues. This chapter thus discusses both the legal and the political formation MacCormick received in and thanks to Oxford and considers what impact this had on his character.
