The distinction between qualitative and non-qualitative properties should be familiar from discussions of the principle of the identity of indiscernibles: two otherwise exactly similar individuals, Castor and Pollux, might share all their qualitative properties yet differ with respect to their non-qualitative properties—for while Castor has the property being identical to Castor, Pollux does not. But while this distinction is familiar, there has not been much critical attention devoted to spelling out its precise nature. I argue that the class of non-qualitative (...) properties is broader than it is often taken to be. When properly construed, it will not only include properties such as being identical to Castor, which somehow make reference to particular individuals, it will also include more general properties such as identity, composition, set membership, as well as various peculiarly ontological properties. Given that some of these more general properties help to explain objective similarity, we have reason to believe that there are fundamental non-qualitative properties. (shrink)

The ArgumentRecent historiography of the Scientific Revolution has challenged the assumption that the achievements of seventeenth-century natural philosophy can easily be described as the ‘mechanization of the world-picture.’ That assumption licensed a story which took mechanization as self-evidently progressive and so in no need of further historical analysis. The clock-work world was triumphant and inevitably so. However, a close examination of one key group of natural philosophers working in England during the 1670s shows that their program necessarily incorporated souls and (...) spirits, attractions and congruities, within both their ontology and their epistemology. Any natural philosophical strategy which excluded spirits and sympathies from its world was condemned as tending to subversion and irreligion. This examination shows that the term ‘mechanical philosophy’ was a category given its meanings within local contexts and carries no universal sense separate from that accomplished by these natural philosophers. It also shows how the experimental praxis was compelled to treat souls and spirits, to produce them through experimental labor, and then to extend these experimentally developed entities throughout the cosmos, both social and natural. The development of mechanical philosophy cannot be used to explain the cognitive and social structure of this program, nor its success: instead, the historical setting of experimental work shows how a philosophy of matter and spirit was deliberately constructed by the end of the seventeenth century.

ArgumentThis paper argues that Samuel Clarke's account of agent causation (i) provides a philosophical basis for moderate voluntarism, and (ii) both leads to and benefits from the acceptance of partial occasionalism as a model of causation for material beings. Clarke's account of agent causation entails that for an agent to be properly called an agent (i.e. causally efficacious), it is essential that the agent is free to choose whether to act or not. This freedom is compatible with the existence of (...) conceptually necessary connections. Hence, Clarke can harmonize God's freedom of choosing with the existence of eternal and necessary relations among things. Moreover, in Clarke's account, only intelligent entities can be properly understood as efficacious causes. Beings deprived of intelligence are not agents or efficacious causes at all and their effects are thus the result of the immediate action of some intelligent being operating upon them. (shrink)

A critical discussion of Shoemaker's argument for the possibility of time without change, intended as an argument against relationist conceptions of time. A relational view of time is proposed based on the primitive identity of events (or whatever entities are the basic subjects of change and lack thereof).

Recent decades have seen a revived interest in super-substantivalism, the idea that spacetime is the only fundamental substance and matter some kind of aspect, property or consequence of spacetime structure. However, the metaphysical debate so far has misidentified a particular variant of super-substantivalism with the position per se. I distinguish between a super-substantival core commitment and different ways of fleshing it out. I then investigate how general relativity and alternative spacetime theories square with the different variants of super-substantivalism.

Essay review of Daniel Garber, 1992, Descartes' Metaphysical Physics, University of Chicago Press, Chicago and London, xiv + 389 pp., and Michael Friedman,: 1992, Kant and the Exact Sciences, Harvard University Press, Cambridge, Mass., and London, xvii + 357 pp. These two books display the historical connection between science and philosophy in the writings of Descartes and Kant. They show the place of science in, or the scientific context of, these authors' central metaphysical doctrines, pertaining to substance and its properties, (...) the metaphysics of force and causal agency, the relation of geometry to matter and to space, and the structure of cognition. In so doing, they provide an image of philosophy as an intellectually and culturally engaged enterprise, an image according to which it makes little sense to make pronouncements about the foundations of knowledge or the possibilities for science without direct engagement with the living practice of scientific and other cognitive enterprises. However, in some areas they did not engage the context as fully as needed; their interpretations of particular arguments and indeed of whole philosophical programs suffered thereby. (shrink)

There is a long tradition of preferring local theories to ones that posit lawful or causal influence at a spacetime distance. In this paper, we argue against this preference. We argue that nonlocality is scientifically unobjectionable and that nonlocal theories can be known. Scientists can gather evidence for them and confirm them in much the same way that they do for local theories. We think these observations point to a deeper constraint on scientific theorizing and experimentation: the (quasi‐) isolation of (...) causal or lawful influence. We argue that this requirement ought to replace the locality desideratum in science. We then explore the possibility that the order of explanation has been reversed: perhaps it is isolatable influence that determines what counts as local in the first place. (shrink)

In this paper, I explore various views on which mind-body dualism is true, but the soul is located in the body. I argue that this sort of dualism (which I call 'somatic dualism') once was a not-uncommon view in the philosophy of mind. I also argue that it has the resources to reply to some of the problems thought to affect Cartesian dualism.

Change in the human past, studied by historians, includes changes in philosophy's past, which can be explained by causes, motives and reasons. In the case of philosophy, must explanatory antecedents of change always be philosophical? Should philosophers ever treat non-philosophical reasons as belonging to the history of philosophy? Saying ‘never’ is absolutely internalist, while ‘sometimes’ rejects this absolutely internalist rule. To show that ‘sometimes’ is the better answer, I examine two case histories from the early modern period: these cases, framed (...) by a taxonomy of historical narrative, eliminate absolute internalism.

Most academic publications refer to Parkour as a subversive and embodied tactic that challenges hegemonic discourses of discipline and control. Architecture becomes the playful ground where new ways to move take form. These approaches rarely address the material and embodied relations that occur in these practices and remain on the discursive plane of cultural signifiers. A theory of movement between bodies as the founding aspect of Parkour unfolds alternative concepts of body, space, time and movement beyond the discursive. Movement becomes (...) the leitmotif for a re-conceptualization of the relations between subjects and objects and abandons their division. With the example of Parkour, I will challenge anthropocentric approaches toward embodiment and instead foreground open-ended shifting configurations of places and their relation to movement. Parkour re-shapes rigid concepts of places and their human encounter through movement. Through its encounter with obstacles Parkour activates the silent potential for movement located in the relation between bodies and thus reaches beyond material boundaries (e.g., a wall). As a deterritorializing practice, I will use Parkour to re-consider the relations between different bodies such as architectural configurations, subjects and their urban ecologies to develop a relational model for movement to shape our everyday encounters with matter.

Let's begin with an old example. In De Rerum Naturua , Lucretius presented a thought experiment to show that space is infinite. We imagine ourselves near the alleged edge of space; we throw a spear; we see it either sail through the ‘edge’ or we see it bounce back. In the former case the ‘edge’ isn't the edge, after all. In the latter case, there must be something beyond the ‘edge’ that repelled the spear. Either way, the ‘edge’ isn't really (...) an edge of space, after all. So space is infinite. (shrink)
