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.

In the Essay Concerning Human Understanding, Locke insists that all knowledge consists in perception of the agreement or disagreement of ideas. However, he also insists that knowledge extends to outer reality, claiming that perception yields ‘sensitive knowledge’ of the existence of outer objects. Some scholars have argued that Locke did not really mean to restrict knowledge to perceptions of relations within the realm of ideas; others have argued that sensitive knowledge is not strictly speaking a form of knowledge for Locke. This chapter argues that Locke’s conception of sensitive knowledge is in fact compatible with his official definition of knowledge, and discusses his treatment of the problem of skepticism, both in the Essay and in the correspondence with Stillingfleet.

Vere Chappell has pointed out that it is not clear whether Locke has a well-developed ontology or even whether he is entitled to have one.2 Nevertheless, it is clear that Locke believes that there are organisms, and it is clear that he thinks that there are substances. But does he believe that organisms are substances? There are certainly parts of the Essay in which Locke seems unequivocally to state that organisms are substances. For instance, in 2.23.3 Locke uses men and horses as examples of substances. In Locke’s most explicit the account of abstraction, given in 3.3.7-9, organism [vivens] is treated as a sub-species of body and body as a sub-species of substance; so, by transitivity, organism is a kind of substance. Finally, in his discussion of essences in 3.6, Locke uses all of the following organisms as examples of substances: horses, mules, men, sheep, goats, plants, drills, changelings, asses, bulls, cats, and rats. This textual evidence would seem to settle the matter about the ontological status of organisms. However, there are other parts of the Essay in which the ontological status of organisms is less clear, to say the least. In fact, there are texts in which Locke seems to state (or at least to be committed to the..

In 1769, the English bishop and theologian Edmund Law published a Defence of Mr. Locke's Opinion concerning Personal Identity.1 In this work, Law attempted to 'explain and vindicate Mr. Locke's hypothesis' (301) by offering a new account of Lockean persons. Law's account centers around three key claims. First, persons are modes — very roughly, properties — rather than substances. Second, the relevant properties are those that make moral evaluation appropriate, thus taking seriously Locke's insistence that 'person' is a forensic term. And third, the fact that persons are modes is what makes a demonstrative science of morality possible.I am not convinced that Law's interpretation actually vindicates Locke, though it ..

It is here argued that Locke and Newton held very similar views on the nature of our knowledge of substance: our only cognitive access to substances is through their powers to affect our minds and other substances. However, in spite of this shared empiricist foundation, Locke and Newton held divergent views on the unification of powers or qualities into a single substance. While Locke allows that distinct powers can be understood as united in one substance (indeed all substances are collections of powers for Locke), this paper argues for an interpretation of Newton according to which substance cannot have distinct powers. Rather, a substance just is a power in space and time.
