In disproof of the materialist principle, that common things exist unperceived, and in defence of the New Principle, Philonous here objects that it is inconceivable that a common thing should do so. Hylas replies that, on the contrary, we can and do think of, e.g., a tree standing alone as opposed to a tree being perceived by an observer. But Philonous counter-objects to this reply that it contains a contradiction, since it asserts that we can think of something which is (...) not thought of. (shrink)

According to Berkeley, then, the unconscious process of inference of the scientist goes as follows. He notices that, when he does not have his house within visual range, he cannot see it just by wishing to; and that, when he does have it within visual range and his eyes open, he cannot prevent himself from seeing it just by wishing not to. He therefore infers that he is not the efficient cause of these sensations. But, since he holds that they (...) must have some efficient cause, he concludes that this is a congeries of "material substances," which are numerically distinct and partly dissimilar from the sensations, and which exist even when unperceived, or "externally to the mind." As a psychological theory, this seems to be at any rate plausible. (shrink)

Both these developments would have surprised Berkeley. He would have found it paradoxical that the vulgar should have rejected his vulgar immaterialism as paradoxical, since he of course believed himself to be on their side in the matter, and characterised his own philosophy as a.

Hitherto, the standard edition of Berkeley's works has been A. C. Fraser's of 1901, published by the Oxford University Press. The chief differences between the two editions are these. Professors Luce and Jessop give of each text the latest edition published by Berkeley himself, adding all significant variations in any earlier editions in footnotes, whereas Fraser followed no uniform procedure, and sometimes combined different editions. This difference is obviously an improvement. Further, Professor Luce's edition of Berkeley's pair of notebooks, which (...) he calls Philosophical Commentaries and which Fraser called Commonplace Book of occasional metaphysical thoughts, differs radically from Fraser's; Professor Luce has also given a different, and better, text of the Theory of Vision Vindicated. Finally, Volume II of the new edition amplifies Berkeley's brief correspondence with the American philosopher, Samuel Johnson, since it contains Johnson's letters to Berkeley, in which he questions some points in Berkeley's system, whereas Fraser published Berkeley's replies only. The editors' notes and introductions are brief, and have been written with the primary aim of presenting an accurate text. This policy is welcome, since it remains all too true that, as Professor Jessop remarks, "hitherto Berkeley has been read far too little, and his expositors far too much"; which, in the case of so excellent a writer as Berkeley, is doubly a pity.
