The first half of this review article on Locke on primary and secondary qualities leads up to a fairly straightforward reading of what Locke says about the distinction in Essay II.viii, one that, in its general outlines, represents a sympathetic understanding of Locke’s discussion. The second half of the paper turns to consider a few of the ways in which interpreting Locke on primary and secondary qualities has proven more complicated. Here we take up what is sometimes called the Berkeleyan (...) interpretation of Locke, the understanding of Locke’s resemblance thesis, and Locke’s views of qualities and their relationship to powers.

Hegel has been widely, though erroneously, supposed to have rejected epistemology in favor of unbridled metaphysical speculation. Reputation notwithstanding, Hegel was a very sophisticated epistemologist, whose views have gone unrecognized because they are so innovative, indeed prescient. Hence I shall boldly state: Hegel's epistemology is of great contemporary importance. In part, this is because many problems now current in epistemology are problems Hegel addressed. In part, this is because of the unexpected effectiveness of Russell's 1922 exhortation, “I should take ‘back (...) to the 18th century’ as a battle-cry, if I could entertain any hope that others would rally to it.” I shall elaborate on these thematic connections between Hegel's views and our problems below (§3), after summarizing the main features of Hegel's epistemology (§2). Thereafter I consider Hegel's views in relation to 20th-century empiricism (§4), Dretske's information theory (§5), and the on-going debate between realists and historicist relativists (§6). Sections 2–4 will be summary in character, for I have discussed these issues in detail elsewhere. Sections 5 and 6 shall consider more closely some important social aspects of Hegel's epistemology. Two themes of my remarks are that Hegel anticipated by 150 years the recent rejections in epistemology of concept-empiricism and of individualism, and more importantly, Hegel showed how rejecting these positions does not require rejecting commonsense realism about the objects of empirical knowledge. In part, this is because Hegel rejected “internalism” about mental content. The recent wave of anti-Cartesianism in epistemology and philosophy of mind has much to learn from Hegel. Benefiting from Hegel' insights and analyses, however, requires understanding just what were Hegel's aims, methods, and arguments in epistemology. These, however, have eluded most commentators, whether critical or sympathetic. So I begin by reviewing the main points of Hegel's epistemology. (shrink)

Many today agree that philosophy, as an academic discipline, must, for the sake of its very survival, become more inclusive of a wider range of perspectives, coming from a more diverse pool of philosophers. Yet there has been little serious reflection on how our very idea of what philosophy is might be preventing this change from taking place. In this essay I would like to consider the ways in which our ideas about philosophy's relation to tradition, and its relation to (...) other dimensions of human culture, influence efforts to promote greater diversity in the field.

In response to widespread doubts among professional philosophers (Russell, Horwich, Dietrich, McGinn, Chalmers), Stoljar argues for a ‘reasonable optimism’ about progress in philosophy. He defends the large and surprising claim that ‘there is progress on all or reasonably many of the big questions.’ However, Stoljar’s caveats and admitted avoidance of historical evidence permits overlooking persistent controversies in philosophy of mind and cognitive science that are essentially unchanged since the 17th Century. Stoljar suggests that his claims are commonplace in philosophy departments (...) and, indeed, the evidence I adduce constitutes an indictment of the widely shared view among professional analytic philosophers.

Assume for the sake of argument that doing philosophy is intrinsically valuable, where “doing philosophy” refers to the practice of forging arguments for and against the truth of theses in the domains of metaphysics, epistemology, ethics, and so on. The practice of the history of philosophy is devoted instead to discovering arguments for and against the truth of “authorial” propositions, that is, propositions that state the belief of some historical figure about a philosophical proposition. I explore arguments for thinking that (...) doing history of philosophy is valuable—specifically, valuable in such a way that its value does not reduce to the value of doing philosophy. Most such arguments proffered by historians of philosophy fail, as I show. I then offer a proposal about what makes doing history of philosophy uniquely valuable, but it is one that many historians will not find agreeable. (shrink)

Locke claimed that God superadded various powers to matter, including motion, the perfections of peach trees and elephants, gravity, and that he could superadd thought. Various interpreters have discussed the question whether Locke's claims about superaddition are in tension with his commitment to mechanistic explanation. This literature assumes that for Locke mechanistic explanation involves deducibility. We argue that this is an inaccurate interpretation and that mechanistic explanation involves a different type of intelligibility for Locke.

Postpositivists have lately joined post‐Husserlians in arguing that the deepest problem with Descartes' legacy is that it fosters the objectivist illusion that philosophers might actually come to think “from Nowhere,” or at least that they can self‐consciously choose whatever presuppositions they do accept. Yet this argument is easier to express than to incorporate into one's own thinking. It is perfectly possible to oppose the View from Nowhere, and even to criticize others for failing to understand its impossibility, and still do (...) so … as if from Nowhere. This article is concerned with such compromised opposition—that is, with critics who reject, in ahistorical terms and from an ahistorical standpoint, an ahistorical conception of philosophy. It focuses on two figures from the empiricist‐positivist side of the Cartesian legacy, Rorty and Taylor, but their story is in important ways typical. Though their criticisms are certainly more radical and considerably more successful than those of many of their analytic colleagues, each retains in his own thinking more of the ahistorical or standpointless ideal than he realizes.

Since 1976 Hilary Putnam has drawn parallels between his "internal", "pragmatic", "natural" or "common-sense" realism and Kant's transcendental idealism. Putnam reads Kant as rejecting the then current metaphysical picture with its in-built assumptions of a unique, mind-independent world, and truth understood as correspondence between the mind and that ready-made world. Putnam reads Kant as overcoming the false dichotomies inherent in that picture and even finds some glimmerings of conceptual relativity in Kant's proposed solution. Furthermore, Putnam reads Kant as overcoming the (...) pernicious scientific realist distinction between primary and secondary qualities, between things that really exist and their projections, a distinction that haunts modern philosophy. Putnam's revitalisation of Kant is not just of historical interest, but challenges contemporary versions of scientific realism. Furthermore, Putnam has highlighted themes which have not received the attention they deserve in Kantian exegesis, namely, the problematic role of primary and secondary qualities in Kant's empirical realism, and the extent of Kant's commitment to conceptual pluralism.However, I argue that Putnam's qualified allegiance to Kant exposes him to some of the same metaphysical problems that affected Kant, namely, the familiar problem of postulating an absolute reality (Ding an sich), while at the same time disavowing the meaningfulness of so doing. In conclusion I suggest that Putnam might consider Hegel's attempts to solve this problem in Kant as a way of furthering his own natural realism. (shrink)

This paper engages critically with Dimitri Gutas’ recent characterization of post-classical Islamic philosophy and theology as a form of paraphilosophy or intellectual activity that merely simulates philosophy. I argue that this view arises from a misguided understanding of the concept of philosophy that should provide the standard for its historiography. In order to avoid a number of problematic consequences, such as gaps in historical continuity or a disconnection from what we understand by philosophy today, we must take our cue from (...) a sufficiently uncontroversial contemporary concept of philosophy instead of any particular historical concept, such as the Peripatetic amalgam of metaphysics, theory of science, and the empirical sciences. Such a strategy provides a sound basis for the inclusion of post-classical thinkers, as well as many classical thinkers who are not falāsifa, in the history of Islamic philosophy without vicious circularity or loss of a normative concept of philosophy.

The relationships between philosophy and its history have been discussed at great length along the last decades. We analyze some aspects of this debate. Particularly, we question the thesis according to which to know history of philosophy is a necessary condition for doing philosophy. We disclose some assumptions, generally implicit ones, strongly related to it.

Recent authors hold that the role of historical scholarship within contemporary philosophical practice is to question current assumptions, to expose vestiges or to calibrate intuitions. On these views, historical scholarship is dispensable, since these roles can be achieved by nonhistorical methods. And the value of historical scholarship is contingent, since the need for the role depends on the presence of questionable assumptions, vestiges or comparable intuitions. In this paper I draw an analogy between scientific and philosophical practice, in order to (...) float one role for historical scholarship that is nonreplicable and noncontingent. It has long been acknowledged that cognitive values – features of theories that facilitate understanding, such as ontological parsimony, ideological simplicity, computational ease and fecundity – play a key role within science. The role of some of these values within philosophy also has received attention but left understudied are the values of novelty and conservativeness. These values influence theory choice, the selection of methodology, the setting of research agenda, and the presentation of results; and are best assessed with a historically informed evaluation. This role for historical scholarship is not replicable by nonhistorical methods, and is not contingent on the presence of questionable assumptions, vestiges or comparable intuitions. (shrink)

Consider the distinctive qualitative property grass visually appears to have when it visually appears to be green. This property is an example of what I call sensuous color. Whereas early modern mechanists typically argue that bodies are not sensuously colored, Margaret Cavendish (1623–73) disagrees. In cases of veridical perception, she holds that grass is green in precisely the way it visually appears to be. In defense of her realist approach to sensuous colors, Cavendish argues that (i) it is impossible to (...) conceive of colorless bodies, (ii) the very possibility of color experience requires that bodies are sensuously colored, and (iii) the attribution of sensuous colors to bodies provides the best explanation of color constancy. Although some passages might suggest that Cavendish endorses a reductive account of sensuous color, according to which sensuous color reduces to a body's microscopic surface texture (or some other mechanistically respectable property), I argue that she accepts a nonreductive account, on which sensuous color is not thus reducible.

Locke’s argument for the primary-secondary quality distinction is compared with Descartes’s argument (in the Principles of Philosophy) for the distinction between mechanical modifications and sensible qualities. I argue that following Descartes, Locke’s argument for the primary-secondary quality distinction is an essentially a priori argument, based on our conception of substance, and the constraints on intelligible bodily interaction that this conception of substance sets.

Although the importance, both historically and systematically, of the seventeenth century distinction between primary and secondary qualities is commonly recognised, there is no consensus on its exact nature. Apparently, one of the main difficulties in its interpretation is to tell the constitutive from the argumentative elements. In this paper, we focus on the primary-secondary quality distinctions drawn by Boyle and Locke. We criticise, more specifically, MacIntosh’s analysis of them. On the one hand, MacIntosh attributes too many different primary-secondary quality distinctions (...) to Boyle and Locke. On the other hand, he forbears to attribute a particular primary-secondary quality distinction to them, which, at least in the case of Boyle, differs genuinely from his main distinction between the mechanical affections of matter and all of matter’s other qualities.
