Wittgenstein’s opinion of G.E. Moore was ambivalent. On the one hand, he admired Moore’s precision of expression and his uncompromising intellectual honesty. At the same time, in conversation with Russell he remarked about Principia Ethica: ‘Unclear statements don’t get a bit clearer by being repeated’ (see Monk 1990, 262; McGuinness 1988, 109). Worse still, he seems to have declared: ‘Moore? – he shows you how far a man can go who has absolutely no intelligence whatever’ (Leavis, 1984, 51).
