Malebranche argues that ideas are representative beings existing in God. He defends this thesis by an inference to the best explanation of human perception. It is well known that Malebranche’s theory of vision in God was forcefully rejected by philosophers such as Arnauld, Locke, and Berkeley. However, the notion that ideas exist in God was not the only controversial aspect of Malebranche’s approach. Another controversy centered around Malebranche’s view that ideas are to be understood as posits in an explanatory theory. (...) Opponents of this approach, including Arnauld and Locke, held that our talk about ideas was not explanatory but instead merely descriptive: we use the word ‘idea’ to describe phenomena that we observe by reflecting on our own minds. This controversy has not received much attention from scholars, but in the present paper I will show that it was an explicit and important subject of concern for Malebranche, Arnauld, Locke, and Berkeley and that attention to this controversy can illuminate several aspects of these philosophers’ work.

This article canvases the main areas of controversy: the nature of Lockean signification and his position on propositions and particles.

Both Reid and Berkeley reject ‘representationalism’, an epistemological position whereby we perceive things in the world indirectly via ideas in our mind, on the grounds of anti-scepticism and common sense. My aim in this paper is to draw out the similarities between Reid and Berkeley's ‘anti-representationalist’ arguments, whilst also identifying the root of their disagreements on certain fundamental metaphysical issues. Reid famously rejects Berkeley's idealism, in which all that exists are ideas and minds, because it undermines the dictates of common (...) sense. Reid also charges Berkeley with not only accepting but furthering the progress of ‘the Way of Ideas’, a longstanding tradition which has drawn philosophy away from true science and common sense. From Berkeley's perspective, Reid is a ‘materialist’; that is, he dogmatically accepts that mind-independent things exist. I argue that these important differences can be explained by both thinkers’ construal of certain ‘philosophical prejudices’. Finally, I conclude that despite these differences, both ought to be characterised as ‘anti-representationalists’ in light of their shared epistemological concerns. (shrink)

John Locke’s claims about relations (such as cause and effect) and mixed modes (such as beauty and murder) have been controversial since the publication of the Essay. His earliest critics read him as a thoroughgoing anti-realist who denies that such things exist. More charitable readers have sought to read Locke’s claims away. Against both, I argue that Locke is making ontological claims, but that his views do not have the absurd consequences his defenders fear. By examining Locke’s texts, as well (...) as the intellectual context in which they were written, I show that Locke’s position is at once radical and thoroughly traditional. (shrink)

Discussions of John Locke’s theory of causation tend, understandably, to focus on the related notion of power and in particular the dialectic with David Hume. But Locke faces a very different threat, one that is internal to his view. For he argues both that causation is a relation and that relations are not real. The obvious conclusion is intolerable. And yet the premises, I argue, are unassailable. Building on an interpretation of Locke’s treatment of relations I have developed elsewhere, I (...) show how Locke can at once speak meaningfully of causation and deny its mind-independent existence.

Ideas play at least two roles in Locke's theory of the understanding. They are constituents of ‘propositions,’ and some of them ‘represent’ the qualities and sorts of surrounding bodies. I argue that each role involves a distinct kind of intentional directedness. The same idea will in general be an ‘idea of’ two different objects, in different senses of the expression. Identifying Locke's scheme of twofold ‘ofness’ reveals a common structure to his accounts of simple ideas and complex ideas of substances. (...) A consequence is a distinction among substance sorts parallel to one of his distinctions between primary and secondary qualities. (shrink)

In this encyclopedia entry I canvass the current interpretations of John Locke's concept of Real Essence and the role it plays in his philosophy.
