This paper offers an epistemic defense of empathy, drawing on John Locke's theory of ideas. Locke held that ideas of shape, unlike ideas of color, had a distinctive value: resembling qualities in their objects. I argue that the same is true of empathy, as when someone is pained by someone's pain. This means that empathy has the same epistemic value or objectivity that Locke and other early modern philosophers assigned to veridical perceptions of shape. For this to hold, pain and (...) pleasure must be a primary quality of the mind, just as shape is a primary quality of bodies. Though Locke did not make that claim, I argue that pain and pleasure satisfy his criteria for primary qualities. I consider several objections to the analogy between empathy and shape-perception and show how Locke's theory has resources for answering them. In addition, the claim that empathetic ideas are object-matching sidesteps Berkeley's influential objection to Locke's theory of resemblance. I conclude by briefly considering the prospects for a similar defense of empathy in contemporary terms. (shrink)

Locke defines knowledge as the perception of the agreement or disagreement of ideas. Nevertheless, he claims that we know particular things: the identity of our ideas, our own existence, and the existence of external objects. Although much has been done to reconcile the definition of knowledge with our knowledge of external objects, there is virtually nothing in the scholarship when it comes to knowing ideas or our own existence. I fill in this gap by arguing that perceptions of ideas are (...) complex mental states that convey propositional knowledge due to agreeing elements therein. (shrink)

How language works — its functions, mechanisms, and limitations — matters to the early moderns as much as it does to contemporary philosophers. Many of the moderns make reflection on language central to their philosophical projects, both as a tool for explaining human cognition and as a weapon to be used against competing views. Even in philosophers for whom language is less central, we can find important connections between their views on language and their other philosophical commitments.

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)
