This paper examines the pressures leading two very different Early Modern philosophers, Descartes and Locke, to invoke two ways in which thought is directed at objects. According to both philosophers, I argue, the same idea can simultaneously count as “of” two different objects—in two different senses of the phrase ‘idea of’. One kind of intentional directedness is invoked in answering the question What is it to think that thus-and-so? The other kind is invoked in answering the question What accounts for (...) the success of our proper methods of inquiry? For Descartes as well as Locke, the two kinds of “ofness” come apart as a result of strong rationalist commitments. However, I will suggest that even if we reject such commitments, we go wrong if we assume that a single kind of intentional directedness suffices to address both questions. (shrink)

How are we to understand philosophical claims about sense perception being direct versus indirect? There are multiple relevant notions of perceptual directness, so I argue. Perception of external objects may be direct on some notions, while indirect on others. My interest is with the sense in which ideas count as perceptual mediators in the philosophy of Descartes and Locke. This paper has two broader aims. The first is to clarify four main notions of perceptual directness. The second is to support (...) my contention that in the texts characterizing ideas as immediate objects of perception, Descartes and Locke are invoking the notion of directness I call 'objectual'. This notion is modeled on the way a picture mediates perception of the pictured object. The upshot of my account is that – with respect to the objectual notion of directness – Descartes and Locke each hold an indirect theory of perception. (shrink)

Thomas Reid distinguished between natural and artificial language and argued that natural language has a very specific sort of priority over artificial language. This paper critically interprets Reid's discussion, extracts a Reidian explanatory argument for the priority of natural language, and places Reid's thought in the broad tradition of Cartesian linguistics.

This article is an extended analysis of the most recent scholarly work on Locke's account of sensitive knowledge. Lex Newman's "dual cognitive relations" model of sensitive knowledge is examined in detail. The author argues that the dual cognitive relations model needs to be revised on both philosophical and historical grounds. While no attempt is made to defend Locke's position, the aim is to show that it is at least consistent, contrary to the received view. The final section provides textual support (...) for the interpretation. (shrink)

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)
