Since the Mind, in all its Thoughts and Reasonings, hath no other immediate Object but its own Ideas, which it alone does or can contemplate, it is evident, that our Knowledge is only conversant about them. (Locke, Essay 4.1.1)
Berkeley's Principles is a curious work. The nominal topic is epistemic. The actual topic is ontological. And it is not uncommon to suggest that ‘Berkeley's System presents us with unique puzzles, particularly at its foundation.’
If, as many commentators suggest, Berkeley's principal arguments for idealism are weak, this might suggest that we are approaching his works from a set of assumptions Berkeley did not share. In this paper I explore such a possibility.
