The defense of common sense in Berkeley's Three Dialogues is, first and foremost, a defense of the gardener's claim to know this cherry tree, a claim threatened by both Cartesian and Lockean philosophy. Berkeley's defense of the gardener's knowledge depends on his claim that the being of a cherry tree consists in its being perceived. This is not something the gardener believes; rather, it is a philosophical analysis of the rules unreflectively followed by the gardener in his use of the (...) word 'exists'. It is by following these rules that the gardener gains knowledge of the cherry tree. Uncovering these deep connections between Berkeley's epistemology and his philosophy of language and placing them in the context of his critique of both Cartesian and Lockean philosophy will clarify Berkeley's strategy for bringing his reader back to common sense and practical engagement in the ordinary affairs of life.

George Berkeley's New Theory of Vision is frequently read as a simple precursor or “half-way house” to his later metaphysics. As a result, some allege the value of the New Theory has been overlooked as critics judge it by its association with immaterialism. In this piece I examine the ongoing debate over the nature of the connection between Berkeley's early work on perception and his later immaterialist tracts. I identify four principal positions on the nature of the connection that have (...) been advanced in the scholarly literature, critically engage the evidence for and against them, and finally weigh in by arguing that an excellent case can be made for thinking that the New Theory is a half-way house to immaterialism after all.

The paper provides an account of necessary truths in Berkeley based upon his divine language model. If the thesis of the paper is correct, not all Berkeleian necessary truths can be known a priori.

To the great puzzlement of his readers, Berkeley begins by arguing that nothing exists other than minds and ideas, but concludes by claiming to have defended the existence of bodies. How can Berkeley's idealism amount to such a defense? I introduce resources from Berkeley's philosophy of language, and especially his analysis of the discourse of physics, to defend a novel answer to this question. According to Berkeley, the technical terms of physics are meaningful despite failing to designate any reality; their (...) meaningfulness derives from the useful role they play in organizing and predicting our experience. I argue that Berkeleian bodies have the same status as these theoretical entities: they are mere 'quasi-entities' introduced by our ways of speaking and thinking in order to serve our practical purposes. Berkeley nevertheless considers this to be a defense of the existence of bodies because he endorses a radically deflationary semantics for 'exists.'. (shrink)
