1 C. D. Broad, “Berkeley's Argument about Material Substance,” Proceedings of the British Academy, Vol. 28, 1942, 11. My paper contends that Berkeley's doctrine of the perceivable makes him an epistemological realist and not a phenomenalist. This interpretation of Berkeley is not, of course, new; in recent years it has received forceful support from two distinguished Berkeleian scholars, A.A. Luce and T.E. Jessop. On the subject of this paper in particular see Luce, Berkeley's Immaterialism (Edinburgh, 1945), 45-46 and “Berkeley's Doctrine of the Perceivable,” Hermathena, Vol. 60, 1942, passim. Cf. also J.P. de C. Day, “George Berkeley, 1685-1753,” The Review of Metaphysics, Vol. 6, esp. 110-111 , 270-281, and K. Marc-Wogau, “Berkeley's Sensationalism and the Esse est Percipi-Principle”, Theoria, Vol. 23, 1957, 12-36. Other recent studies which treat Berkeley as an epistemological realist are: W. Doney, “Two Questions about Berkeley”, Philosophical Review, Vol. 61, 1952, 382-391; D. Grey, “The Solipsism of Bishop Berkeley”, Philosophical Quarterly, Vol. 2, ig52, 338-349; H.M. Bracken, “Berkeley's Realisms”, Philosophical Quarterly, Vol. 8, 1958, 3-15.

11 Mill formulated an objection to Berkeley's view of actual perception turning on the ambiguity of the word ‘same’ as applied to sensations in Berkeley's view. Cf. John Stuart Mill, “Berkeley's Life and writings” in Fortnightly Review, 1871, 517-518. Cf. also Day, op. cit., 271-273, who has reformulated Mill's argument in a way in which the force of the objection is more clearly brought out.
