Helen Knight and Margaret Macdonald on the meaning of ‘good’

I argue that Helen Knight and Margaret Macdonald expressed views on the nature of 'good' in aesthetic contexts which anticipate to a striking extent the dispute between Peter Geach and R. M. Hare over ethical uses of 'good' several years later. I show that Knight introduced a distinction between uses of adjectives later drawn also by Geach, and that she employed that distinction, as Geach did, in order to defend a descriptivist approach to 'good' according to which 'good' is not ambiguous. I also show that Macdonald conceived of evaluative statements as commendatory, and that her conception of evaluative language therefore closely resembles the position which Hare would later advance.
