This essay offers an original interpretation and defense of the doctrine of flux, as it is presented in Plato’s Theaetetus. The methodology of the paper’s analysis is in the style of rational reconstruction, and it is highly analytic in scope, in the sense that I will focus on the text itself, and only on certain parts of it too, while ignoring the rest of Plato’s extensive corpus, and without worrying about whether, how, and to what extent the interpretation of the (...) view coheres well with the other elements of the secret doctrine view discussed in the dialogue, as well. In the first part of the essay, I’ll offer my interpretation of the doctrine. Then, in the second part of the essay, I’ll examine two potential criticisms of the doctrine, including Socrates’s infamous linguistic paradox, and show how my interpretation of Heraclitean flux metaphysics is able to circumvent both.

The time-lag argument seems to put some pressure on naïve realism to agree that seeing must happen simultaneously with what is seen; meanwhile, a wide-accepted empirical fact suggests that light takes time to transmit from objects at a distance to perceivers—which implies what is seen happened before seeing, and, accordingly, naïve realism must be false. In this paper, I will, first of all, show that the time-lag argument has in fact involves a misunderstanding concept of simultaneity: according to Special Relativity, (...) simultaneity is a matter of convention rather than a matter of fact, so, in principle, we can stipulate a perceptual conception of simultaneity, according to which what is seen is simultaneous with seeing. Secondly, the generalized time-lag argument has a mistaken view on the perceived events and perceiving; it has a doubtful assumption that these events are momentary in the mathematical sense. Such idealization is the main reason why we have the intuition that the time-lag effect of perceiving is in conflict with our ordinary perceptual experiences. Finally, I argue that the naïve realist account of the perceptual relation is a nontemporal constitutive relation; and hence naïve realism is compatible with the claim that we can perceive things as they were, and it should not be weakened by the time-lag argument.

I argue that Plato thinks that the soul has location, surface, depth, and extension, and that the Timaeus’ composition of the soul out of eight circles is intended literally. A novel contribution is the development of an account of corporeality that denies the entailment that the soul is corporeal. I conclude by examining Aristotle’s objection to the Timaeus’ psychology and then the intellectual history of this reading of Plato.

I argue that scientific and poetic modes of objectivity are perspectival duals: 'views' from and onto basic natural forces, respectively. I ground this analysis in a general account of objectivity, not in terms of either 'universal' or 'inter-subjective' validity, but as receptivity to basic features of reality. Contra traditionalists, bare truth, factual knowledge, and universally valid representation are not inherently valuable. But modern critics who focus primarily on the self-expressive aspect of science are also wrong to claim that our knowledge (...) is or should be ultimately mediated by ourselves. In objective science, we represent nature as a field of phenomena determined by and within explanatorily-basic physical structures that encode the causal impact of elemental physical forces. These causally-basic forces hence ground the possibility of objective scientific theory, even though (I argue) they are systematically excluded from its representational contents. I show how my notions of force and field emerge partly through my effort to naturalize concepts of 'God' and 'Laws' in 17th-century natural philosophy. In science, we use the structure of basic forces' impact to see corresponding objects. We do not see these forces themselves—and this relates to the 'transcendence' of 'God'. I supplement this historical analysis by critiquing standard accounts of objectivity, and by synthesizing elements from neo-Kantian epistemology and current 'structural' realism into a view that I call 'dynamic structuralism'. Finally, I argue that physics systematically relies on passive characterizations of phenomena like inertia and impressed force. Dynamic alternatives that are just as empirically adequate are possible, but they are non-scientific. Poetic objectivity involves a direct presentation of nature as an order of interacting forces. I elaborate first by developing a novel theory of the relation between beauty and sublimity, mediated by a basic category of 'sensory force' (e.g. a 'singing' tone in a beautiful melody). I then describe the interaction between sensory and affective dimensions of aesthetic experience, in relation to an original historical analysis of passion and 'disinterestedness' in Kant, Schiller and Nietzsche. I synthesize these lines of analysis into a critique of the role of 'expression' in art. I also resist 'spectator'-centric aesthetics, in this connection, by developing an account of artistic objectivity in dialogue with Ruskin's critique of the 'pathetic fallacy'. I contrast artistic objectivity with Romantic ideals of self-expression, while elaborating its positive relation to certain currents within Victorian and Modernist aesthetics, including Imagists' stress on 'exteriority'. My project creatively extends Nietzsche's view that philosophical and scientific theories are 'perspectival' expressions of theorists' drives. It is a virtue of Nietzsche's account that he takes the outlet of strong human drives in creative acts of theorizing to be just one among many higher modes of 'will to power' in nature—many of which are totally impersonal. But Nietzsche is still too focused on self-expression or willing one's own power. Objective science involves external forces' 'expression' in and through us, not just 'expressing' our own powers. And Nietzsche's vitalistic 'will to power' must be replaced by a basic ontology that better accommodates inorganic phenomena, like the 'lawful' order of celestial motions. Thus I aim to de-anthropomorphize and 'de-organicize' post-Kantian notions of willful striving and organic development, while preserving for force the primary ontological and evaluative status that theorists from Schiller and Goethe to Schelling and Schlegel to Emerson and Nietzsche attributed to will or to life.

I defend a how-possibly argument for Kantian (or Kant*-ian) transcendental idealism, drawing on concepts from David Chalmers, Nick Bostrom, and the cyberpunk subgenre of science fiction. If we are artificial intelligences living in a virtual reality instantiated on a giant computer, then the fundamental structure of reality might be very different than we suppose. Indeed, since computation does not require spatial properties, spatiality might not be a feature of things as they are in themselves but instead only the way that (...) things necessarily appear to us. It might seem unlikely that we are living in a virtual reality instantiated on a non-spatial computer. However, understanding this possibility can help us appreciate the merits of transcendental idealism in general, as well as transcendental idealism’s underappreciated skeptical consequences.

The history of the Parallelogram Rule for composing physical quantities, such as motions and forces, is marked by conceptual difficulties leading to false starts and halting progress. In particular, authors resisted the required assumption that the magnitude and the direction of a quantity can interact and are jointly necessary to represent the quantity. Consequently, the origins of the Rule cannot be traced to Pseudo-Aristotle or Stevin, as commonly held, but to Fermat, Hobbes, and subsequent developments in the latter part of (...) the seventeenth century.

Bachelard regarded the scientific changes that took place in the early twentieth century as the beginning of a new era, not only for science, but also for philosophy. For him, the theory of relativity and quantum mechanics had shown that a new philosophical ontology and a new epistemology were required. I show that the type of philosophy with which he was more closely associated, in particular that of Léon Brunschvicg, offered to him a crucial starting point. Brunschvicg never considered scientific (...) objects as independent of the mind, and as a consequence questions such as the existence of particles independently of the mind, theory or apparatus, were absent from his philosophy, which was rather aimed at analyzing the mind critically, and above all historically. Bachelard accepted the fundamental ideas of Brunschvicg’s philosophy; however, his own reading of contemporary science enabled him to go beyond it, as shown by his emphasis on the social production of knowledge, and by his removal of the distinction between ideas and technologically produced objects of knowledge. For him, modern science teaches philosophy that knowledge is not a phenomenology but rather a ‘phenomenotechnique’. I argue that Bachelard’s view that philosophy ‘should follow science’ stems from moral considerations.Keywords: Gaston Bachelard; Léon Brunschvicg; Phenomenotechnique; Chosisme; Theory of relativity; Quantum mechanics.

According to Heidegger's Being and Time, social relations are constitutive of the core features of human agency. On this view, which I call a ‘strong conception’ of sociality, the core features of human agency cannot obtain in an individual subject independently of social relations to others. I explain the strong conception of sociality captured by Heidegger's underdeveloped notion of ‘being-with’ by reconstructing Heidegger's critique of the ‘weak conception’ of sociality characteristic of Kant's theory of agency. According to a weak conception, (...) sociality is a mere aggregation of individual subjects and the core features of human agency are built into each individual mind. The weak conception of sociality remains today widely taken for granted. I show that Christine Korsgaard, one of the most creative contemporary appropriators of Kant, operates with a weak conception of sociality and that this produces a problematic explanatory deficiency in her view: she is unable to explain the peculiar motivational efficacy of shared social norms. Heidegger's view is tailor made to explain this phenomenon. I end by sketching how Heidegger provides a social explanation of a major systematic concern animating Korsgaard, the concern with the importance of individual autonomy and answerability in human life.

Contemporary studies in unconscious cognition are essentially founded on dissociation, i.e., on how it dissociates with respect to conscious mental processes and representations. This is claimed to be in so many and diverse ways that one is often lost in dissociation. In order to reduce this state of confusion we here carry out two major tasks: based on the central distinction between cognitive processes and representations, we identify and isolate the main dissociation paradigms; we then critically analyze their key tenets (...) and reported findings.

Recent Cartesian scholarship postulates two Descartes, separating Descartes into a scientist and a metaphysician. The purpose varies, but one has been to show that the metaphysical Descartes, of the Meditations, is less genuine than the scientific Descartes. Accordingly, discussion of God and the soul, the evil demon, and the non-deceiving God were elements of rhetorical strategy to please theologians, not of serious philosophical argumentation. I agree in finding two Descartes, but the two I identify are not scientist and philosopher, but (...) practitioner and methodologist of the mathematical sciences on the one hand, and metaphysician of a new, general science of nature on the other. This chapter examines the transition to the second Descartes, and especially the metaphysical turn. It proposes that although Descartes' doubt was methodological and he felt no serious threat from skepticism and absolute certainty was not his primary goal. Rather, the doubt was used to reform the intellect, or to teach the use of the pure intellect (and to obtain certainty in that domain). Further, Descartes' metaphysics was primarily in the service of his natural philosophy (where in the main he did not claim absolute certainty). He did not talk about God and the soul in order to fool the theologians. His discussion of the relation between God and human reason was part of a metaphysical strategy in which, through his doctrine on the eternal truths, he separated knowledge of the first principles of natural philosophy (gained by the natural light) from theological cognition (through the light of grace), thereby seeking to render his metaphysics distinct from the proper domain of theology.

Substantivalism is the view that space exists in addition to any material bodies situated within it. Relationalism is the opposing view that there is no such thing as space; there are just material bodies, spatially related to one another. This paper assesses this issue in the context of classical physics. It starts by describing the bucket argument for substantivalism. It then turns to anti-substantivalist arguments, including Leibniz's classic arguments and their contemporary reincarnation under the guise of ‘symmetry’. It argues that (...) these anti-substantivalist arguments are stronger than is often acknowledged. (shrink)

Algebraic equations in the tradition of Descartes and Frans Van Schooten accompany Christiaan Huygens’s early work on collision, which later would be reorganized and presented as De motu corporum ex percussione. Huygens produced the equations at the same time as his announcement of his rejection of Descartes’s rules of collision. Never intended for publication, the equations appear to have been used as preliminary scaffolding on which to build his critiques of Descartes’s physics. Additionally, Huygens used algebraic equations of this form (...) to accurately predict the speeds of bodies after collision in experiments carried out at the Royal Society. Despite their deceptive simplicity, Huygens’s algebraic equations pose significant conceptual problems both mathematically and for their physical interpretation especially for negative speeds; they may very well have been the source of a new principle, the conservation of quantity of motion with direction.

Newton rested his theory of mechanics on distinct metaphysical and epistemological foundations. After Leibniz's death in 1716, the Principia ran into sharp philosophical opposition from Christian Wolff and his disciples, who sought to subvert Newton's foundations or replace them with Leibnizian ideas. In what follows, I chronicle some of the Wolffians' reactions to Newton's notion of absolute space, his dynamical laws of motion, and his general theory of gravitation. I also touch on arguments advanced by Newton's Continental followers, such as (...) Leonhard Euler, who made novel attempts to defend his mechanical foundations against the pro-Leibnizian attack. This examination grants us deeper insight into the fate of Newton's mechanics on the Continent during the early eighteenth century and, more specifically, sheds needed light on the conflicts and tensions that characterized the reception of Newton's philosophy of mechanics among the Leibnizians.

A god is a cosmic designer-creator. Atheism says the number of gods is 0. But it is hard to defeat the minimal thesis that some possible universe is actualized by some possible god. Monotheists say the number of gods is 1. Yet no degree of perfection can be coherently assigned to any unique god. Lewis says the number of gods is at least the second beth number. Yet polytheists cannot defend an arbitrary plural number of gods. An alternative is that, (...) for every ordinal, there is a god whose perfection is proportional to it. The n -th god actualizes the best universe(s) in the n -th level of an axiological hierarchy of possible universes. Despite its unorthodoxy, ordinal polytheism has many metaphysically attractive features and merits more serious study. (shrink)

By denying to vegetal life the core values of autonomy, individualization, self-identity, originality, and essentiality, traditional philosophy not only marginalizes plants but, inadvertently, confers on them a crucial role in the current transvaluation of metaphysical value systems. From the position of absolute exteriority and heteronomy, vegetation accomplishes a living reversal of metaphysical values and points toward the collapse of hierarchical dualisms.

According to vitalism, living organisms differ from machines and all other inanimate objects by being endowed with an indwelling immaterial directive agency, ‘vital force,’ or entelechy . While support for vitalism fell away in the late nineteenth century many biologists in the early twentieth century embraced a non vitalist philosophy variously termed organicism/holism/emergentism which aimed at replacing the actions of an immaterial spirit with what was seen as an equivalent but perfectly natural agency—the emergent autonomous activity of the whole organism. (...) Organicists hold that organisms unlike machines are ‘more than the sum of their parts’ and predict that the vital properties of living things can never be explained in terms of mechanical analogies and that the reductionist agenda is doomed to failure. Here we review the current status of the mechanist and organicist conceptions of life particularly as they apply to the cell. We argue that despite the advances in biological knowledge over the past six decades since the molecular biological revolution, especially in the fields of genetics and cell biology the unique properties of living cells have still not been simulated in mechanical systems nor yielded to reductionist—analytical explanations. And we conclude that despite the dominance of the mechanistic–reductionist paradigm through most of the past century the possibility of a twentyfirst century organicist revival cannot be easily discounted.

This paper provides a general philosophical groundwork for the theoretical and applied normative evaluation of information generally and digital information specifically in relation to the good life. The overall aim of the paper is to address the question of how Information Ethics and computer ethics more generally can be expanded to include more centrally the issue of how and to what extent information relates and contributes to the quality of life or the good life , for individuals and for society. (...) To answer that question, the paper explores and provides by way of a theoretical groundwork for further research, the concept of wisdom understood as a type of meta - knowledge as well as a type of meta - virtue , which can enable one to both know in principle what a good life is and how to successfully apply that knowledge in living such a life in practice. This answer will be based on the main argument presented in this paper that the notion of wisdom understood as being at once a meta - epistemological , meta - axiological and meta - eudemonic concept, provides the essential conceptual link between information on the one hand and the good life on the other. If, as we are told, this is the Age of Information, both the theoretical examination and analysis of the question of how information relates to the good life and the provision of an adequate answer to that question are essential for developing a deeper understanding of how to evaluate the theoretical and practical implications and ramifications of information for the good life, for individuals and societies generally.

During the 1630s Descartes recognized that he could not expect all legitimate claims in natural science to meet the standard of absolute certainty. The realization resulted from a change in his physics, which itself arose not through methodological reflections, but through developments in his substantive metaphysical doctrines. Descartes discovered the metaphysical foundations of his physics in 1629-30; as a consequence, the style of explanation employed in his physical writings changed. His early methodological conceptions, as preserved in the Rules and sketched (...) in Part Two of the Discourse, pertained primarily to his early work in optics. By the early 1630s, Descartes was concerned with new methodological problems pertaining to the postulation of micro-mechanisms. Recognition of the need to employ a method of hypothesis led him to lower the standard of certainty required of particular explanations in his mature physics. (shrink)

In this paper I argue that whether or not a computer can be built that passes the Turing test is a central question in the philosophy of mind. Then I show that the possibility of building such a computer depends on open questions in the philosophy of computer science: the physical Church-Turing thesis and the extended Church-Turing thesis. I use the link between the issues identified in philosophy of mind and philosophy of computer science to respond to a prominent argument (...) against the possibility of building a machine that passes the Turing test. Finally, I respond to objections against the proposed link between questions in the philosophy of mind and philosophy of computer science. (shrink)

Abstract Boyle distinguished clearly between the areas which we would call scientific and theological. However, he felt that they overlapped seamlessly, and that the truths we discovered (or which were revealed to us) in one of these areas would be relevant to us in the other.

Given this background I then consider the relation between hypotheses, theories and facts in Boyle's work, and consider a particular case, that of Boyle's Law, as an exemplification of the claims made in the rest of the paper.

Locke is often interpreted as having attempted to build a foundation for knowledge based on ideas. However, textual evidence shows that the corpuscular philosophy is also a fundamental part of that foundation. Somewhat anachronistically, but also very usefully, Locke can be described as inferring corpuscularianism by an inference to the best explanation. Locke felt justified in believing that the corpuscular philosophy was the correct description of the world because it provided us with a better explanation of a wider variety of (...) phenomena than competing hypotheses.Keywords: John Locke; Robert Boyle; Induction; Inference to the best explanation; Corpuscular philosophy.

Is the phenomenological concept of “body” not, in general, an ideal? The purpose of this article is to defend this thesis within the scope of the French phenomenological tradition. The French phenomenological concept of “lived body” points to an ideal, rather than to our actual experience of the body; and this ideal is none other than that of the soul. The Cartesian ideal of the soul becomes, in the French phenomenological tradition, the ideal of the body—of a body that is (...) determined, in return, by the soul’s properties. The French concept of “lived body” results indeed from two forms of idealization that will be exposed successively: the epistemological idealization that consists in attributing, to the body, the soul’s mode of knowledge as a cogito; the practical idealization that consists in attributing, to the body, the soul’s mode of power and action as an unlimited will. This twofold gesture finds its paradigmatic expression in Michel Henry’s phenomenology of the body, but can also be seen at work in Sartre, Ricœur and Merleau-Ponty. (shrink)

It is common to assume that Descartes did not have a conception of an object's matter density independently of its size, but this is a rather incomplete assessment of the early modern natural philosopher's theory. Key to our understanding of Descartes's physics is a consideration of the ratios between the quantities of the different types of matter in which an object consists. As these ratios determine the degree of an object's porosity and elasticity, they also affect in Descartes's theory the (...) phenomena of gravity and weight. (shrink)

Moderate scientism is the view that empirical science can help answer questions in nonscientific disciplines. In this paper, we evaluate moderate scientism in philosophy. We review several ways that science has contributed to research in epistemology, action theory, ethics, philosophy of language, and philosophy of mind. We also review several ways that science has contributed to our understanding of how philosophers make judgments and decisions. Based on this research, we conclude that the case for moderate philosophical scientism is strong: scientific (...) practice has promoted significant progress in philosophy and its further development should be welcomed and encouraged.

The present reflection draws upon a tradition of energetic, world-facing critical legal scholarship to interrogate the anthropos assumed by the terminology of ‘anthropocentrism’ and of the ‘Anthropocene’. The article concludes that any ethically responsible future engagement with ‘anthropocentrism’ and/or with the ‘Anthropocene’ must explicitly engage with the oppressive hierarchical structure of the anthropos itself—and should directly address its apotheosis in the corporate juridical subject that dominates the entire globalised order of the Anthropocene age.

Some hold that the lesson of Russell’s paradox and its relatives is that mathematical reality does not form a ‘definite totality’ but rather is ‘indefinitely extensible’. There can always be more sets than there ever are. I argue that certain contact puzzles are analogous to Russell’s paradox this way: they similarly motivate a vision of physical reality as iteratively generated. In this picture, the divisions of the continuum into smaller parts are ‘potential’ rather than ‘actual’. Besides the intrinsic interest of (...) this metaphysical picture, it has important consequences for the debate over absolute generality. It is often thought that ‘indefinite extensibility’ arguments at best make trouble for mathematical platonists; but the contact arguments show that nominalists face the same kind of difficulty, if they recognize even the metaphysical possibility of the picture I sketch.

Descartes was both metaphysician and natural philosopher. He used his metaphysics to ground portions of his physics. However, as should be a commonplace but is not, he did not think he could spin all of his physics out of his metaphysics a priori, and in fact he both emphasized the need for appeals to experience in his methodological remarks on philosophizing about nature and constantly appealed to experience in describing his own philosophy of nature. During the 1630s, he offered empirical (...) support for the basic principles of his natural philosophy, while also promising to provide a metaphysical justification. He offered the metaphysical justification in the Meditations and Principles. and claimed absolute certainty for it. At the same time, he recognized that the particular postulated mechanisms of his natural philosophy did not reach that standard of certainty. These mechanisms were supported by empirical testing or confirming of causes through observed effects. (shrink)

Theories of cognition and theories of social practices and institutions have often each separately acknowledged the relevance of the other; but seldom have there been consistent and sustained attempts to synthesize these two areas within one explanatory framework. This is precisely what my dissertation aims to remedy. I propose that certain recent developments and themes in philosophy of mind and cognitive science, when understood in the right way, can explain the emergence and dynamics of social practices and institutions. Likewise, the (...) view I construct explains how social practices and institutions shape the character of cognition of their constituent agents. Moreover, I explain both cognitive and social agency under the single explanatory framework provided by Dynamic Systems Theory. Drawing upon the phenomenological tradition, "embodied, "extended", "embedded", "enactive", and "ecological" approaches to cognition, as well as the conceptual resources of Dynamic Systems Theory, I construct a theory of agency that sees cognitive and social agents as far-from-equilibrium, open, recursively self-maintenant dynamic systems. Depending on the specifics of concrete circumstances, such systems, which I call "Dynamic Embodied Agents", may develop and possess emergent capacities for error-detection, flexible learning, normative behavior, representation, self-reflection, various modes of pattern-recognition, a temporal sense of self, and even moral responsibility. Some such systems are also sensitive to perceived social influences ; while reciprocally constituting and causally affecting them. (shrink)

What begins with an unlikely collection of unrelated phenomena--mechanical dolls, weather, atoms, lyric poetry--blossoms in the course of _Toy Medium_ into a subtle and persuasive meditation on one of Western philosophy's biggest puzzles: the relation of mind and matter. What is the role of the imagination in defining material substance? In a dazzling study of the poetics of materialist philosophy and of the materialism of lyric poetry, Daniel Tiffany traces the historical conjunction of matter and metaphor through a remarkable range (...) of topics: automata in classical antiquity and the eighteenth century; Kepler's treatise on snowflakes; animal magnetism; fireworks and cloud-chamber photographs; the origins of the microscope as a philosophical toy and its bearing on the figure of the virtuoso. At critical junctures in modern Western culture, Tiffany finds uncanny parallels between the metaphorics of science and visions of material substance rooted in popular culture and lyric poetry. _Los Angeles Times Best Nonfiction Book of 2000_.

Two definitions of Mach’s principle are proposed. Both are related to gauge theory, are universal in scope and amount to formulations of causality that take into account the relational nature of position, time, and size.

In this paper I offer three main challenges to James (2011). All three turn on the nature of philosophy and secure knowledge in Spinoza. First, I criticize James's account of the epistemic role that experience plays in securing adequate ideas for Spinoza. In doing so I criticize her treatment of what is known as the ‘conatus doctrine’ in Spinoza in order to challenge her picture of the relationship between true religion and philosophy. Second, this leads me into a criticism of (...) her account of the nature of philosophy in Spinoza. I argue it is less piecemeal and less akin to what we would recognize as ‘science’ than she suggests. Third, I argue against James's core commitment that Spinoza's three kinds of knowledge differ in degree; I claim they differ in kind. My argument will offer a new interpretation of Spinoza's conception of ‘common notions’. Moreover, I argue that Spinozistic adequate knowledge involves something akin to angelic disembodiment.

The mathematical nature of modern science is an outcome of a contingent historical process, whose most critical stages occurred in the seventeenth century. ‘The mathematization of nature’ (Koyré 1957 , From the closed world to the infinite universe , 5) is commonly hailed as the great achievement of the ‘scientific revolution’, but for the agents affecting this development it was not a clear insight into the structure of the universe or into the proper way of studying it. Rather, it was (...) a deliberate project of great intellectual promise, but fraught with excruciating technical challenges and unsettling epistemological conundrums. These required a radical change in the relations between mathematics, order and physical phenomena and the development of new practices of tracing and analyzing motion. This essay presents a series of discrete moments in this process. For mediaeval and Renaissance philosophers, mathematicians and painters, physical motion was the paradigm of change, hence of disorder, and ipso facto available to mathematical analysis only as idealized abstraction. Kepler and Galileo boldly reverted the traditional presumptions: for them, mathematical harmonies were embedded in creation; motion was the carrier of order; and the objects of mathematics were mathematical curves drawn by nature itself. Mathematics could thus be assigned an explanatory role in natural philosophy, capturing a new metaphysical entity: pure motion. Successive generations of natural philosophers from Descartes to Huygens and Hooke gradually relegated the need to legitimize the application of mathematics to natural phenomena and the blurring of natural and artificial this application relied on. Newton finally erased the distinction between nature’s and artificial mathematics altogether, equating all of geometry with mechanical practice. (shrink)

Many commentators have suggested that the metaphysical portions of Emilie du Châtelet's Institutions de physique are a mere retelling of Leibniz's views. I argue that a close reading of the text shows that du Châtelet's cosmological argument and discussion of God's nature contains both Lockean and Leibnizian elements. I discuss where she follows Locke in her arguments, what Leibnizian elements she brings in, and how this enables her to avoid some of the mistakes commonly attributed to Locke's formulation of the (...) cosmological argument. I show that while du Châtelet accepts the causal principle ex nihilo nihil fit, she does not utilize Locke's stronger causal principle. I also discuss her use of the principle of sufficient reason in both improving the Lockean cosmological argument and in proving the attributes of God. (shrink)

A philosophical standard in the debates concerning material constitution is the case of a statue and a lump of clay, Goliath and Lumpl, respectively. According to the story, Lumpl and Goliath are coincident throughout their respective careers. Monists hold that they are identical; pluralists that they are distinct. This paper is concerned with a particular objection to pluralism, the Grounding Problem. The objection is roughly that the pluralist faces a legitimate explanatory demand to explain various differences she alleges between Lumpl (...) and Goliath, but that the pluralist’s theory lacks the resources to give any such explanation. In this paper, I explore the question of whether there really is any problem of this sort. I argue (i) that explanatory demands that are clearly legitimate are easy for the pluralist to meet; (ii) that even in cases of explanatory demands whose legitimacy is questionable the pluralist has some overlooked resources; and (iii) there is some reason for optimism about the pluralist’s prospects for meeting every legitimate explanatory demand. In short, no clearly adequate statement of a Grounding Problem is extant, and there is some reason to believe that the pluralist can overcome any Grounding Problem that we haven’t thought of yet.

Many philosophers categorise judgment as a type of action. On the face of it, this claim is at odds with the seeming fact that judging a certain proposition is not something you can do voluntarily. I argue that we can resolve this tension by recognising a category of non-voluntary action. An action can be non-voluntary without being involuntary. The notion of non-voluntary action is developed by appeal to the claim that judging has truth as a constitutive goal. This claim, when (...) combined with a conception of judging as a way of settling a question, explains both why judging is genuinely agential, and why it is nevertheless non-voluntary. (shrink)

: In this paper I address the vexed question of secondary causation in René Descartes' physics, and examine several influential interpretations, especially the one recently proposed by Dennis Des Chene. I argue that interpreters who regard Cartesian bodies as real secondary causes, on the grounds that the modes of body include real forces, contradict Descartes' account of modes. On the other hand, those who deny that Descartes affirms secondary causation, on the grounds that forces cannot be modes of extension, commit (...) Descartes to the problematic view that the undetermined and immutable will of God is the sole cause of determinate and variable motions. Des Chene's contextualist approach to Descartes' texts leads him to an intermediate position that combines elements of both interpretations. However, in my view, Des Chene's interpretation likewise fails to resolve apparent tensions in Descartes' claims. I thus propose to separate the issue of secondary causation from what Des Chene dubs 'the problem of force'. On the basis of this approach, and a study of Jesuit commentaries familiar to Descartes, I develop a new interpretation which takes seriously Descartes' claim that the laws of nature are the secondary and particular causes of particular motions and changes in motion.

This study explores several arguments against Spinoza's philosophy that were developed by Henry More, Samuel Clarke, and Colin Maclaurin. In the arguments on which I focus, More, Clarke, and Maclaurin aim to establish the existence of an immaterial and intelligent God precisely by showing that Spinoza does not have the resources to adequately explain the origin of motion. Attending to these criticisms grants us a deeper appreciation for how the authority derived from the empirical success of Newton's enterprise was used (...) to settle debates within philosophy. What I emphasize is that in the progression from More to Clarke to Maclaurin, key Newtonian concepts from the Principia (1687), such as motion, atomism, and the vacuum, are introduced and exploited in order to challenge the account of matter and motion that is presented in Spinoza's Ethics (1677). Building on this treatment, I use the arguments from More and Clarke especially to help discern the anti-Spinozism that can be detected in Newton's General Scholium (1713). Ultimately, the Newtonian criticisms that I detail offer us a more nuanced view of the problems that plague Spinoza's philosophy, and they also challenge the idea that Spinoza seamlessly fits into a progressive narrative about the scientific revolution.

The status of fundamental laws is an important issue when deciding between the three broad ontological options of fundamentalism (of which the thesis that physics is complete is typically a sub-type), emergentism, and disorder or promiscuous realism. Cartwright’s assault on fundamental laws which argues that such laws do not, and cannot, typically state the facts, and hence cannot be used to support belief in a fundamental ontological order, is discussed in this context. A case is made in defence of a (...) moderate form of fundamentalism, which leaves open the possibility of emergentism, but sets itself against the view that our best ontology is disordered. The argument, taking its cue from Bhaskar, relies on a consideration of the epistemic status of experiments, and the question of the possible generality of knowledge gained in unusual or controlled environments.

This paper offers a close reading of Patañjali’s Yogasūtra through the concepts of abhyāsa and vairāgya, “repetitive practice” and “dispassion,” drawing on Patañjali’s classical commentators and on Krishnachandra Bhattacharyya’s “Studies in Yoga Philosophy,” an forgotten chapter of his corpus. I open with a critical examination of Patañjali’s citta-vṛtti scheme, his attempt of “mapping” the contents of consciousness. Thereafter, I discuss the “procedure of yoga,” based on the mutual operation of abhyāsa and vairāgya for the sake of nirodha, cessation of the (...) vṛttis, or “movements” of consciousness. A close analysis of Patañjali and his commentators indicates that both abhyāsa and vairāgya are depicted as consisting of a strong reflective dimension. This is to say that the radical meditative act of “emptying” the consciousness of its objective content is in fact a rational conclusion of the mind, as it reflects upon itself. This reflection is both sensitive to the “limitedness” of the objective world and “receptive” to the silent presence of the “unlimited” selfhood beyond, which Patañjali, following the Sāṃkhya tradition, refers to as puruṣa. It is implied here that the yogic act of disengagement from the worldly and objective is as much an act of will, as it is an act of self-sacrifice. Finally, the analysis offered here reveals substantial “philosophical threads” in the Yogasūtra, a text which is usually considered as too “practical,” or “therapeutic,” or “spiritual,” to be “really” philosophical.

This is the first book to focus on Descartes's changing views, and it is welcome."--Roger Ariew, University of South Florida.

For a long time, under the influence of traditional Western philosophy, Orthodox interpreters have distorted Marx’s philosophy as the ontology of matter, thereby concealing the essence of Marx’s philosophy, and eliminating the fundamental difference between Marx’s philosophy and traditional philosophy. This paper proposes that Marx’s philosophy is not the ontology of matter, but on the contrary, by examining the ontology of matter, Marx put forward his own ontological theory, i.e., the ontology of the praxis-relations of social production, by which Marx (...) linked the realms of phenomenon and essence, revealing the content and essence of his philosophy.

Some truths about color are knowable a priori. For example, it is knowable a priori that redness is not identical to the property of being square. This extremely modest and plausible claim has significant philosophical implications, or so I shall argue. First, I show that this claim entails the falsity of standard forms of color functionalism, the view that our color concepts are functional concepts that pick out their referents by way of functional descriptions that make reference to the subjective (...) responses of perceivers. I then argue that, while some sophisticated forms of color functionalism can accommodate the a priori knowability of a truth like “redness is not identical to squareness,” they can only do so by abandoning color realism, the thesis that colors are instantiated by external material objects. In practice, color functionalists are almost invariably color realists. Thus, given extremely modest assumptions concerning what can be known a priori about color, we should conclude that color functionalism, at least in its typical realist form, is false. (shrink)
