Abstract
That the legacy of Berkeley's philosophy has been a largely sceptical one is perhaps rather surprising. For he himself took it as one of his objectives to undermine scepticism. He roundly denied that there were ‘any principles more opposite to Scepticism than those we have laid down’ . Yet Hume was to write of Berkeley that ‘most of the writings of that very ingenious author form the best lessons of scepticism, Bayle not excepted’. And it has become something of a commonplace to say that Berkeley's philosophy is sceptical in direction, if not in intention. He is represented as a half-hearted sceptic, applying radical empiricist principles in his treatment of matter but baulking at their implications when he came to consider spirits. Hume is credited with being the more thoroughgoing of the two. Berkeley had denied the substantiality of extended things. Hume felt obliged, by parity of reasoning, to deny the substantiality of the self. On his account of the mind there is ‘properly no simplicity in it at one time, nor identity in different’ . It is commonly supposed that Berkeley, in maintaining the quite contrary view that we know ourselves to be simple, undivided beings , showed a lack of rigour or consistency.
