Tom Stoneham offers a clear and detailed study of Berkeley's metaphysics and epistemology, as presented in his classic work Three Dialogues between Hylas and Philonous, originally published in 1713 and still widely studied. Stoneham shows that Berkeley is an important and systematic philosopher whose work is still of relevance to philosophers today.

The void is deadly. If you were cast into a void, it would cause you to die in just a few minutes. It would suck the air from your lungs. It would boil your blood. It would drain the warmth from your body. And it would inflate enclosures in your body until they burst}.

Does a penny viewed at an angle in some sense look elliptical, as though projected on a two-dimensional surface? Many philosophers have said such things, from Malebranche (1674/1997) and Hume (1739/1978), through early 20th-century sense-data theorists, to Tye (2000) and Noë (2004). I confess that it doesn't seem this way to me, though I'm somewhat baffled by the phenomenology and pessimistic about our ability to resolve the dispute. I raise geometrical complaints against the view and conjecture that views of this (...) sort draw some of their appeal from over-analogizing visual experience to painting or photography. Theorists writing in contexts where vision is typically analogized to less-projective media--wax signet impressions in ancient Greece, stereoscopy in introspective psychology circa 1900--are substantially less likely to attribute such projective distortions to visual appearances.

I have previously argued that within an argument to show that we cannot perceive the causes of our sensations, Berkeley's Philonous conflates a psychological and an epistemic sense of 'immediately perceive', and uses the principle of perceptual immediacy (PPI), that whatever is perceived by the senses is immediately perceived. George Pappas has objected that Berkeley does not operate with either of these concepts of immediate perception, and does not subscribe to (PPI). But I show that Berkeley's argumentative strategy requires him (...) to use these two concepts, and that the concept of immediate perception Pappas attributes to Berkeley would weaken this strategy. I also defend attributing to Berkeley a slightly modified version of (PPI), on which it both serves his strategy and allows sense perception to incorporate what he calls 'suggestion'. (shrink)
