Upon turning nineteen, he was sent to continue his studies at the University of Glasgow, where he attended the lectures of Adam Smith. While at Glasgow, Boswell decided to convert to Catholicism and become a monk. Upon learning of this, his father ordered him home. Instead of obeying, though, Boswell ran away to London, where he spent three months, living the life of a libertine, before he was taken back to Scotland by his father. Upon returning, he was re-enrolled at Edinburgh University and forced by his father to sign away most of his inheritance in return for an allowance of £100 a year.
