Abstract

Foot examines the moral theory known as ‘non‐cognitivism’. Her central thesis is that all non‐cognitivist moral theories are based on the same serious mistake. This mistake is traced to a distinction taken for granted by non‐cognitivist moral philosophers such as A. J. Ayer and R. M. Hare. Such philosophers wrongly believed that there is a logical gap between ‘descriptive language’ and ‘evaluative language’. Foot argues that this supposed gap between facts and values, which crucially gives a logical gap between a moral judgement and its grounds, is a chimera.
