Trevor Rollings read English at Cambridge, then taught for forty years in three countries, mainly as Head of Faculty. His experience teaching 'theory of knowledge' led him to realise that to understand fully how the mind works, we need to unify our ways of knowing in the sciences, arts and humanities, which are often in conflict. His enquiries resulted in a series of seven books called Empires of the Mind. His eighth title, The Stupendous Story of Us, is his first Unicorn book.
