When Robert Cross went to Aberdeen University as Regius Professor of Logic in 1953, philosophy teaching was divided into two traditional departments – Moral Philosophy and Logic and Metaphysics – and an elementary course in philosophy was compulsory for arts students. These aspects were to change radically. Aberdeen was still then a small, local university with the traditions of Scottish higher education firmly in place. Students came largely from the North-East region, there were no student residences, and “meal Monday” was used to enable students to return home for a break. In his first few years Cross, with Wladek Bednarowski, established up-to-date courses in logic, general philosophy and the history of philosophy which emphasised the virtues of clarity, careful analysis and common sense typical of Oxford philosophy at the time. Cross’s own major philosophical work was Plato’s Republic: a philosophical commentary, written with A. D. Woozley (his part being written in his distinctive near-indecipherable handwriting, sometimes known as “Linear C”) and published in 1964. It was written not as a new work of scholarship but as a patient, careful survey of the arguments in the Republic which students at all levels would find accessible and illuminating. The book had the characteristic care and lucidity in outlining Plato’s views which were typical of Cross’s writing and teaching. It has been widely used ever since. He took great satisfaction from learning in the mid-1990s that students continued to take substantial numbers of photocopies from the book; and it is still prominently cited as a basic text for students.
