 In 1919 Anderson married fellow philosophy student Jenny Baillie, was appointed assistant lecturer at University College of South Wales (where he also provided Workers’ Education Classes) and was subsequently appointed assistant lecturer in logic at the University of Glasgow. In 1920 he was appointed lecturer at the University of Edinburgh and so became the main exponent of realism in Norman Kemp Smith’s Department of Logic and Metaphysics. In the same year, his brother William accepted the Chair of Mental and Moral Philosophy at Auckland University College, New Zealand.
