Fergus Kerr, "Aquinas after Wittgenstein," p. 1
Anthony Kenny once suggested that 'the points on which Aquinas differed from his medieval critics are precisely the points on which Wittegenstein, in his later philosophical writing, was at variance with positivist thought.' On several important issues, 'Aquinas was opposed by Scotus in a way remarkably similar to the way in which Wittgenstein was opposed to the positivists'.
...
...there are, on the other hand, four topics about which Aquinas and Wittgenstein may be regarded as being on the same side against Scotists and logical positivists respectively. Aquinas favoured analogy, Scotus believed in univocity. Wittgenstein deployed 'family likeness' over against verificationism. Scotus misunderstood Aristotelian hylomorphism; Wittgenstein mocked logical atomism. For Scotus the mind had direct knowledge of particulars; Wittgenstein attacked the notion of the primacy of ostensive definition. Finally, for Aquinas intellectual knowledge was an active process, whereas Scotus regarded it as receptive, like sense-perception; logical-positivist epistemology made a similar mistake, while Wittgenstein strove to elimante sense-datum theories.
