Abstract This paper illustrates how Aristotle's topological theses about change in Physics 5-6 can help address metaphysical issues. Two distinctions from Physics 5. 1 are discussed: changing per se versus changing per aliud ; motion versus change. Change from white to black is motion and alteration, whereas change from white to not white is neither. But is not every change from white to black identical with a change from white to not white? (...) Theses from Physics 6 refute the identity. Is change from white to black at least accompanied by change from white to not white? Perhaps, but given further theses from Physics 6, this supposition yields unwelcome consequences. Most likely, when something changes from white to black it changes merely per aliud , not per se , from white to not white. Genuine change between white and not white is found elsewhere; its admission has bearing on Aristotle's theory of perception. (shrink)

This chapter considers Aristotle's requirements for perceptible objects qua movable, changeable, and perceptible, namely that they must be extended in three dimensions, movable in space, and capable of physical contact with other extended bodies.

Mr William Charlton ) quotes Russell on Motion. It has been pointed out to me that the book referred to in line 5 as Principles of Philosophy should in all probability be The Principles of Mathematics , and on looking into the matter I find that this is indeed the case. On p. 473 of the latter book I read: 447. It is to be observed that … we must entirely reject the notion of a state of motion. (...) Motion consists merely in the occupation of different places at different times, subject to continuity as explained in Part V. (shrink)

Both Heraclitus and Democritus, as the philosophers of historia peri phuseôs, consider nature and human character, habit, law and soul as interrelated emphasizing the links between phusis, kinesis, ethos, logos, kresis, nomos and daimon. On the one hand, Heraclitus’s principle of change (panta rhei) and his emphasis on the element of fire and cosmic motion ultimately dominate his ethics reinforcing his ideas of change, moderation, balance and justice, on the other, Democritus’s atomist description of phusis and (...) class='Hi'>motion underlies his principle of moderation and his ideas of health and measured life. In this series, particularly referring to the main principles of motion, moderation and justice, I attempt to describe a coherent pre-Socratic ethical perspective based on the Heraclitean and Democritean fragments. I explore the connections between their physics and ethics also borrowing from Nietzsche’s lectures and writings on the Pre-Socratics. I redefine such Heraclitean and Democritean concepts as harmony, order, perfection, health, self-control, contentment, cheerfulness, concord, sound judgment, wisdom, measure and balance and discuss them under the principles of motion (phusis), moderation (sophrosyne) and justice. In doing so, I also expose the relevance of the Heraclitean notion of logos (interpreting it as the underlying categorical principle of transition between phusis and ethos) in bringing together these ideas and principles. Finally, based on this pre-Socratic Weltanschauung, I assess the possibility of a coherent picture of humanity, its nature and conduct as extending from or fitting into or extending-from-when-fitting-into the cosmos of moving forces and atoms.

The objective in the present paper is to analyze the aspect of subjectivity having to do with construing motion and change where no motion and change exists outside the representation, that is, in cases where the conceptualizer does not intend to convey the idea that these properties exist in the state of affairs described. In the process of doing so, I will elaborate on a critique of the notion of fictivity as it is currently being used (...) in cognitive linguistics. (shrink)

In his essay “Things Do Not Move,” Sengzhao (374?−414 CE), a prominent Chinese Buddhist philosopher, argues for the thesis that the myriad things do not move in time. This view is counter-intuitive and seems to run counter to the Mahayana Buddhist doctrine of emptiness. In this book chapter, I assess Sengzhao’s arguments for his thesis, elucidate his stance on the change/nonchange of things, and discuss related problems. I argue that although Sengzhao is keen on showing the plausibility of the (...) thesis, he actually views the myriad things as both changing and unchanging and upholds the nonduality of motion and rest. In fact, the nonmoving thesis follows from the discernment that things change from moment to moment without there being any enduring stuff in the process. Among philosophical works that confer a higher ontological status on nonchange over change, Sengzhao’s essay is unique and well worth pondering. (shrink)

Perceived size is a function of viewing distance, retinal images size, and various contextual cues such as linear perspective and the size and location of neighboring objects. Recently, we demonstrated that illusion magnitudes of classic visual size illusions may be greatly enhanced or reduced by adding dynamic elements. Specifically, a dynamic version of the Ebbinghaus illusion (classically considered a “size contrast” illusion) led to a greatly enhanced illusory effect, whereas a dynamic version of the Corridor illusion (a “size constancy” illusion) (...) led to a greatly diminished illusory effect. Although these differences may arise from the different processes underlying these illusions (size contrast vs. size constancy), the dynamic variants we tested in our previous work also differed in the nature of the dynamic elements; specifically, whereas the Dynamic Ebbinghaus included a moving target and inducers that changed size and position, the Dynamic Corridor only included a moving target on a static background. Here, we explore further dynamic versions of the Ebbinghaus illusion and the Corridor and Ponzo illusions by separately manipulating three types of dynamic elements: target motion, context translation, and dynamic changes in context. Across five experiments examining 21 dynamic illusory configurations, adding target motion or a dynamically changing context separately resulted in little-to-no illusory effect. In contrast, the combination of target motion and a dynamically changing context led to a robust size illusion, consistent with an interactive effect. However, illusory effects that exceeded the matched classic, static illusory configuration were only observed for the dynamic versions of the Ebbinghaus illusion and the Revealed Ponzo illusions, in which the contextual elements changed size. We conclude that the combination of target motion and a dynamically changing context are necessary to produce dynamic size illusions, but that enhancement above and beyond static illusions may be largely specific to size contrast effects. Our results have important implications for the integration of motion signals, a ubiquitous environmental stimulus, in the perception of object size. (shrink)

Transhumanism’s ideology is marked by a commitment to the “progress” or “perfection” of the human species through technological means. What transhumanists are after is not just therapeutic intervention or optimization of current human capabilities, but an ontological change from human to posthuman. In this article, I critique transhumanist ideology on the grounds that it fundamentally misunderstands human moral perfection as resulting from forces acting upon us (i.e., technological interventions), rather than an internal change of character. This misunderstanding reflects (...) an impoverished view of the concept of motion brought about by the rise of modern science, which entails certain ontological commitments that are not Christian in nature. I conclude transhumanism is untenable because it rests on a shaky foundation of Newtonian physics, and reduces the world to mere matter and forces. Furthermore, Christian transhumanism is especially flawed, because it is complicit in this severing of creation from its sacramental ontology, from the Being of God. (shrink)

Recent exciting work on Cavendish’s natural philosophy highlights the important role of motion in her system. But what is motion, according to Cavendish? I argue that motion, for Cavendish, is what I call ‘compositional motion’: for a body to be in motion is just for it to divide from some matter and join with other matter. So when Cavendish claims to reduce all natural change to motion, she is really reducing all natural (...) class='Hi'>change to mereological change. Cavendish also uses ‘motion’ to name the power that matter has to set itself in compositional motion. That power is not reducible to local motion. If motion is not local motion and if motive power is not a function of actual motion, then despite her polemics, Cavendish does not reduce natural change to local motion. Instead, she offers a unique and exciting account of natural change. (shrink)

An examination of the ways human movement can be represented as a formal language and how this language can be mediated technologically. In Motion and Representation, Nicolás Salazar Sutil considers the representation of human motion through languages of movement and technological mediation. He argues that technology transforms the representation of movement and that representation in turn transforms the way we move and what we understand to be movement. Humans communicate through movement, physically and mentally. To record and capture (...) integrated movement (both bodily and mental), by means of formal language and technological media, produces a material record and cultural expression of our evolving kinetic minds and identities. Salazar Sutil considers three forms of movement inscription: a written record (notation), a visual record (animation), and a computational record (motion capture). He focuses on what he calls kinetic formalism—formalized movement in such pursuits as dance, sports, live animation, and kinetic art, as well as abstract definitions of movement in mathematics and computer science. He explores the representation of kinetic space and spatiotemporality; the representation of mental plans of movement; movement notation, including stave notation (Labanotation) and such contemporary forms of notation as Choreographic Language Agent; and the impact of digital technology on contemporary representations of movement—in particular motion capture technology and Internet transfer protocols. Motion and Representation offers a unique cultural theory of movement and of the ever-changing ways of representing movement. (shrink)

Introspectively, it appears that we can have experiences as of temporally extended phenomena such as change, motion, and the passage of time. A central question in the ontology of time is whether we can make sense of these experiences without assuming that the passage of time is real. The antireductionist argument against such a possibility maintains that if there is no passage of time, but only static time slices, then our experiences as of arguably temporally extended phenomena cannot (...) be explained. Consequently, insofar as we can have such experiences, reductionists need to show that these experiences are in fact realized by static means. By drawing from cognitive sciences, this is exactly what Laurie A. Paul recently aimed to show. I will argue that Paul’s argumentation fails on two grounds. First, even if her argument for accounting apparent motion by static means is successful, it does not apply to other experiences of temporal phenomena. Second, there are reasons to doubt that even apparent motion is represented by static means. Accordingly, the antireductionist argument remains to be addressed. (shrink)

Motion—and, in particular, local motion or change in location—plays a central role in Kenelm Digby’s natural philosophy and in his arguments for the immateriality of the soul. Despite this, Digby’s account of what motion consists in has yet to receive much scholarly attention. In this paper, I advance a novel interpretation of Digby on motion. According to it, Digby holds that for a body to move is for it to divide from and unify with other (...) bodies. This is a view of motion—as change in relations of parthood—that Alison Peterman attributes to Digby’s contemporary and acquaintance, Margaret Cavendish. Having shown that Digby’s presentation of the view predates Cavendish’s by more than a decade, I make a case that Digby’s work influenced Cavendish’s on this topic. In developing and defending my reading, I consider to what extent the Digbean account of motion and the arguments for it accord with the ideals of the mechanical philosophy emerging in the early modern period.

Scholars have long considered de Philosophia and de Caelo to be in contradiction regarding the nature of the heavenly bodies, particularly with respect to the activity proper to the element composing them. According to the accounts we have of de Philosophia, Aristotle seems to have put forth that stars move because they have minds, and, according to Cicero’s account of the lost text, they choose their actions out of free will. In de Caelo, however, Aristotle seems only to consider that (...) stars engage in the activity of circular motion because it is in their nature to do so, as it is in the nature of, e.g. fire to move upwards or Earth to move downwards. In this paper, I argue against the longstanding view that there is an incompatibility between these two “early” cosmological texts of Aristotle. I aim to show that these two texts endorse complementary, not contradictory, views of the heavenly bodies. I argue that in de Philosophia, Aristotle attributes to stars the intellective counterpart of the spatial motion which is developed in greater depth in de Caelo, while in de Caelo, we see hints of Aristotle’s view in de Philosophia that the stars are also minds and are able to rationally cognize their particular good – a point which is shown in de Caelo 292a18–293a14, where Aristotle attributes both life and praxis to the heavenly bodies. The overarching view which I present of these two texts is that while de Caelo approaches the heavenly bodies qua bodies and de Philosophia approaches them qua minds, they are still examining one and the same substance and that Aristotle has not changed his mind regarding the basic nature of such a substance in the (supposed) interim between writing de Philosophia and de Caelo. Rather, we find echoes of de Caelo in de Philosophia, and echoes of de Philosophia in de Caelo, which speaks to the fact that Aristotle maintains one view of the heavenly bodies which he presents over the course of these two texts.

The doctrine of motion elaborated by Albert the Great has often been interpreted in the light of the debate, which developed in the 14th century, on the alternative between motion as a forma fluens, according to the Avicennian approach, or as a fluxus formae, more in line with Averroes’ position. Projecting this alternative onto Albert retrospectively, however, does not seem to be very productive for at least two reasons: (i) there is not a sufficient textual basis to affirm (...) that he understood the syntagmas forma fluens / fluxus formae as indices of two different and opposing ways of interpreting physical motion; (ii) Albert actually proposes his own interpretation of motion that does not really coincide with either Avicenna’s or Averroes’. In this article, I intend to show how Albert understands motion – particularly in his Physics – as a forma fluens, but in a determinate sense, i.e. as changing according to its being and not according to its essence (secundum suum esse et non secundum suam essentiam). This qualification means that Albert’s position does not coincide in a strict sense with either Avicenna’s or Averroes’, and must instead be understood in close connection with Albert’s doctrine of incohatio formae and the presence, in matter, of a kind of ‘intellectual appetite’. My aim is thus to show how Albert found a way to inscribe the doctrine of the flow of form and the inchoative presence of forms in matter in a Neoplatonic emanationist system (mainly influenced by the Liber de causis) and to rethink the nature and function of the ‘giver of forms’ with respect to the Avicenna model.

Journal Name: Cognitive Linguistics Issue: Ahead of print.

In his In Contradiction (1987), Priest levelled three powerful arguments against the received Russellian view of change and motion. He argued that his preferred paraconsistent theory of change, the Hegelian account, is immune from these objections. Here I argue that these three arguments are sound, but that the Hegelian account falls pray to them too. I conclude, however, that the Hegelian account is in a better position to tackle these challenges.

The philosophy of time and change in Chinese Buddhism originated in a short treatise written by an early Chinese monk, Sengzhao (c. 384-414 CE). In this treatise, “On the Immutability of Things (wubuqianlun),” Sengzhao proposed a revolutionary theory of time and change that opposed the traditional Chinese notion of change established by Confucianism and Daoism. His thesis of the immutability of things also seemingly defies a fundamental Buddhist teaching about the impermanence of things. More than a thousand (...) years after Sengzhao, a monk in the Ming dynasty, Kongyin Zhencheng (1546–1617) published the “Logical Investigation of the Thesis of No-Motion of Things (Wubuqian zhengliang lun) to refute Sengzhao's theory of the immutability of things. Because of Sengzhao's esteemed status as one of the early founders of Chinese Buddhism, Zhencheng's critique of Sengzhao caused an uproar among his contemporaries. The ensuing exchange constituted one of the major debates in the history of Chinese Buddhism (Lin 2018; Liu et al., 2020; Fang 1998; Zhu 2012) and was considered a significant event in the “rise of Buddhist scholasticism” (Liu et al., 2020: 7). This entry will carefully analyze Sengzhao's treatise on time and the immutability of things, highlighting the philosophical disagreements between him and Zhencheng. It will also place Sengzhao in his philosophical lineage to examine how he derived insights from Kumarajiva and Nāgārjuna, and how he might have influenced Chan Buddhism's conception of time. This entry will present the uniqueness of Sengzhao's conception of time that marks his departure from the Chinese tradition. (shrink)

Graduate Papers from the 2022 Joint Session. It is often said that Aristotle takes geometrical objects to be absolutely unmovable and unchangeable. However, Greek geometrical practice does appeal to motion and change, and geometers seem to consider their objects apt to be manipulated. In this paper, I examine if and how Aristotle’s philosophy of geometry can account for the geometers’ practices and way of talking. First, I illustrate three different ways in which Greek geometry appeals to change. (...) Second, I examine Aristotle’s ontology of geometrical objects and argue that although the truth-makers of geometrical statements are in fact unmovable because they are properties of sensible objects, geometers ‘separate them in thought’ and treat them as substances apt to be modified. Finally, I examine whether allowing for the possibility of manipulating these semi-fictional geometrical individuals creates problems for the applicability of geometry. I find that it does not, insofar as one accepts that geometry is not meant to track physical change but merely to study the instantaneous geometrical configuration of sensible bodies, and is thus only applicable at the instant.

Thomas Lynch, called "a cross between Garrison Keillor and William Butler Yeats" (New York Times), reminds us not only of how we die but also of how we live. "The facts of life and death remain the same. We live and die, we love and grieve, we breed and disappear. And between these existential gravities, we search for meaning, save our memories, leave a record for those who will remember us." So writes Thomas Lynch, poet and funeral director, and author (...) of the highly praised The Undertaking, winner of an American Book Award and finalist for the National Book Award, as he continues to examine the relations between the "literary and mortuary arts." The essays assembled here explore the human condition at the intersection of millennia, beleaguered by choices and changes, encumbered by merger and acquisition, numbed by maths and technologies, in search of the meaning of life and time, our lives and times. Lynch tenders life and times--sextons, muckrakers, clergy, caskets, condoms, loved poems, a hated cat, the mall, Main Street. In an age that seeks to define human experience in retail, high-tech, or pop-psyche terms, these essays speak to the existentials: between being human and ceasing to be, between birth and death, we are bodies in motion and at rest.

This book studies various perspectives in the history of European philosophy on the relationship between time and movement. Ever since the pre-Socratic thinker Zeno of Elea linked time and space to understand bodily movement, his so-called paradoxes of motion have remained unsolved. One of his most important critics, the French philosopher Henri Bergson, criticized the usual connection between time and space and established a new way of understanding time as duration (durée). Whereas Zeno presented an objectivist understanding of time, (...) Bergson emphasized its subjectivist meaning. Both contradictory positions seem incompatible, referring to pure intellect (Zeno) on the one hand or pure sensation (Bergson) on the other. Looking at Hegel's Phenomenology, this book shows that the outer and inner consciousness of time became crucial to his principle of movement and change. In his view, time is an integral part of dialectical processes that are historically substantiated. Hegel sought to subordinate pure concepts and ideas so that they would become indispensable moments of the self knowing spirit. Cassirer appreciated the idealism of coming into being but rejected Hegel's concept of the absolute. Instead, he established his philosophy of symbolic forms, in which the development of different perceptions and conceptions of time - from situational affective experience to the mathematical system of relations - determines the direction of the symbolic formation process. In the end, the sensitive concept of time is replaced by the relational concept of natural numbers, in which all here-and-now experiences are embedded. Finally, Bourdieu attempts to reintegrate symbolic forms into social processes. The book reflects on the concepts mentioned here by discussing their pros and cons in order to shed more light on the relationship between time and movement in European thought. (shrink)

This paper reconstructs the relationship between the now, motion, and number in Aristotle to clarify the nature of the now, and, thereby, the relationship between motion and time. Although it is clear that for Aristotle motion, and, more generally, change, are prior to time, the nature of this priority is not clear. But if time is the number of motion, then the priority of motion can be grasped by examining his theory of number. This (...) paper aims to show that, just as numbers are generated by the soul, time is not presupposed by motion, but emerges through the soul’s articulation of motion. Time is co-constituted by the soul and motion. The now is the key to understanding both the contribution of motion and soul to the being of time. The now is part of the soul’s articulation of motion, and sets the stage for an act that distinguishes a unit from its underlying motion. The now, then, sets up an abstraction by which the soul generates the temporal number from motion. Reconstructing this account of abstraction allows us to formulate more strongly Aristotle’s claim to the ontological dependence of time on motion. The paper then gives a systematic overview of the relationships between the now and number in order to address the question of whether the now might be extended. It closes with an examination of the possibility that motion depends on time, and how universal time is possible. (shrink)

The naïve view of temporal experience (Phillips, in: Lloyd D, Arstila V (eds) Subjective time: the philosophy, psychology, and neuroscience of temporality, forthcoming-a) comprises two claims. First, that we are perceptually aware of temporal properties, such as succession and change. Second, that for any temporal property apparently presented in experience, our experience itself possesses that temporal property. In his paper ‘Silencing the experience of change’ (forthcoming), Watzl argues that this second naïve inheritance thesis faces a novel counter-example in (...) the form of the striking motion silencing effects recently demonstrated by Suchow and Alvarez (Curr Biol 21(2):140–143, 2011). Here I clarify the form which any counter-example to naïve inheritance must take. I then explain how, on a plausible, rival ‘crowding’ interpretation of Suchow and Alvarez’s data, motion silencing poses no more of a threat to naïve inheritance than standard cases of change blindness.

There is considerable debate among scholars over whether Descartes allowed for genuine body–body interaction. I begin by considering Michael Della Rocca’s recent claim that Descartes accepted such interaction, and that his doctrine of the creation of the eternal truths indicates how this interaction could be acceptable to him. Though I agree that Descartes was inclined to accept real bodily causes of motion, I differ from Della Rocca in emphasizing that his ontology ultimately does not allow for them. This is (...) not the end of the story, however, since two of Descartes’s successors offered incompatible ways of developing his conflicted account of motion. I contrast the occasionalist view of Nicolas Malebranche that changes in motion derive directly from divine volitions with the non-occasionalist claim of Pierre-Sylvain Regis that such changes derive from a nature distinct from God. In light of Della Rocca’s interpretation, it is noteworthy that the issue of eternal truths is relevant to both alternative accounts. Indeed, Regis took the doctrine that such truths are created to provide crucial support for his alternative to an occasionalist account of body–body interaction. What does not help Della Rocca, however, is that Regis’s view of motion requires a fundamental revision of Descartes’s ontology.

I examine the reasons Aristotle presents in Physics VIII 8 for denying a crucial assumption of Zeno’s dichotomy paradox: that every motion is composed of sub-motions. Aristotle claims that a unified motion is divisible into motions only in potentiality (δυνάμει). If it were actually divided at some point, the mobile would need to have arrived at and then have departed from this point, and that would require some interval of rest. Commentators have generally found Aristotle’s reasoning unconvincing. Against (...) David Bostock and Richard Sorabji, inter alia, I argue that Aristotle offers a plausible and internally consistent response to Zeno. I defend Aristotle’s reasoning by using his discussion of what to say about the mobile at boundary instants, transitions between change and rest. There Aristotle articulates what I call the Changes are Open, Rests are Closed Rule: what is true of something at a boundary instant is what is true of it over the time of its rest. By contrast, predications true of something over its period of change are not true of the thing at either of the boundary instants of that change. I argue that this rule issues from Aristotle’s general understanding of change, as laid out in Phys. III. It also fits well with Phys. VI, where Aristotle maintains that there is a first boundary instant included in the time of rest, but not a “first in which the mobile began to change.” I then show how this rule underlies Aristotle’s argument that a continuous motion cannot be composed of actual sub-motions. Aristotle distinguishes potential middles, points passed through en route to a terminus, from actual middles. The Changes are Open, Rests are Closed Rule only applies to actual middles, because only they are boundaries of change that the mobile must arrive at and then depart from. On my reading, Aristotle argues that the instant of arrival, the first instant at which the mobile has come to be at the actual middle, cannot belong to the time of the subsequent motion. If it did, the mobile would already be moving towards the next terminus and thus, per Phys. VI 6, would have already left. But it cannot have moved away from the midpoint at the very same moment it has arrived there. This means that the instant of arrival must be separated from the time of departure by an interval of rest. I show how Aristotle’s reasoning applies generally to rule out any continuous reflexive motion or continuous complex rectilinear motion. On my interpretation, however, the argument does not apply to every change of direction. When, as in the case of projectile motion, multiple movers and their relative powers explain why the mobile changes directions, distinct sub-motions are not involved. Aristotle holds that such motions cannot be continuous, not because they involve intervals of rest, but because they involve multiple causes of motion. My interpretation of the Changes are Open, Rests are Closed Rule allows us to make better sense of Aristotle’s argument than any previous interpretation. (shrink)

Shepard's analysis of how shape, motion, and color are perceptually represented can be generalized. Apparent motion and shape may be associated with a group of spatial transformations, accounting for rigid and plastic motion, and perceived object color may be associated with a group of illuminant transformations, accounting for the discriminability of surface-reflectance changes and illuminant changes beyond daylight. The phenomenological and mathematical parallels between these perceptual domains may indicate common organizational rules, rather than specific ecological adaptations. [Barlow; (...)

This book exhibits deep philosophical quandaries and intricacies of the historical development of science lying behind a simple and fundamental item of common sense in modern science, namely the composition of water as H2O. Three main phases of development are critically re-examined, covering the historical period from the 1760s to the 1860s: the Chemical Revolution, early electrochemistry, and early atomic chemistry. In each case, the author concludes that the empirical evidence available at the time was not decisive in settling the (...) central debates and therefore the consensus that was reached was unjustified or at least premature. This leads to a significant re-examination of the realism question in the philosophy of science and a unique new advocacy for pluralism in science. Each chapter contains three layers, allowing readers to follow various parts of the book at their chosen level of depth and detail. The second major study in "complementary science", this book offers a rare combination of philosophy, history and science in a bid to improve scientific knowledge through history and philosophy of science.

Can quite different values be rationally weighed against one another? Can the value of one thing always be ranked as greater than, equal to, or less than the value of something else? If the answer to these questions is no, then in what areas do we find commensurability and comparability unavailable? And what are the implications for moral and legal decision making? This book struggles with these questions, and arrives at distinctly different answers.".

This paper is concerned with the senses in which paintings do and do not depict various temporal phenomena, such as motion, stasis and duration. I begin by explaining the popular – though not uncontroversial – assumption that depiction, as a pictorial form of representation, is a matter of an experiential resemblance between the pictorial representation and that which it is a depiction of. Given this assumption, I illustrate a tension between two plausible claims: that paintings do not depict (...) class='Hi'>motion in the sense that video recordings do, and that paintings do not merely depict objects but may depict those objects as engaged in various activities, such as moving. To resolve the tension, I demonstrate that we need to recognise an ambiguity in talk of the appearance of motion, and distinguish between the depiction of motion and the depiction of an object as an object that is moving. Armed with this distinction, I argue that there is an important sense in which paintings depict neither motion, duration, nor – perhaps more controversially – stasis. (shrink)

This paper investigates two puzzles in practical reason and proposes a solution to them. First, sometimes, when we are practically certain that neither of two alternatives is better than or as good as the other with respect to what matters in the choice between them, it nevertheless seems perfectly rational to continue to deliberate, and sometimes the result of that deliberation is a conclusion that one alternative is better, where there is no error in one’s previous judgment. Second, there are (...) striking differences between rational agents – some rational agents have most reason to pursue careers on Wall Street while others have most reason to take up a career in teaching, or scuba diving, or working for political causes. These differences aren’t plausibly explained by ‘passive’ facts about our psychology or their causal interaction with our environment; instead, these facts seem in some sense to ‘express who we are’. But what is this sense? These puzzles disappear if we adopt a novel view about the source of the normativity of reasons – some reasons are given to us and others are reasons in virtue of an act of will. We make certain considerations reasons through an act of will and thus sometimes make it true through an act of agency that we have most reason to do one thing rather than another. (shrink)

This article explores the main similarities and differences between Derek Parfit’s notion of imprecise comparability and a related notion I have proposed of parity. I argue that the main difference between imprecise comparability and parity can be understood by reference to ‘the standard view’. The standard view claims that 1) differences between cardinally ranked items can always be measured by a scale of units of the relevant value, and 2) all rankings proceed in terms of the trichotomy of ‘better than’, (...) ‘worse than’, and ‘equally good’. Imprecise comparability, which can be understood in terms of the more familiar notions of cardinality and incommensurability, rejects only the first claim while parity rejects both claims of the standard view. -/- I then argue that insofar as those attracted to imprecise comparability assume that all rankings are trichotomous, as Parfit appears to, the view should be rejected. This is because imprecise equality is not a form of equality but is a sui generis ‘fourth’ basic way in which items can be ranked. We should, I argue, understand imprecise equality as parity, and imprecise comparability as entailing ‘tetrachotomy’ – that if two items are comparable, one must better than, worse than, equal to, or on a par with the other. Thus those attracted to the idea that cardinality can be imprecise should abandon trichotomy and accept parity and tetrachotomy instead. -/- Finally, I illustrate the difference between Parfit’s trichotomous notion of imprecise comparability and parity by examining how each notion might be employed in different solutions to the problem posed by the Repugnant Conclusion in population ethics. I suggest that parity provides the arguably more ecumenical solution to the problem. (shrink)

This paper begins with a response to Josh Gert’s challenge that ‘on a par with’ is not a sui generis fourth value relation beyond ‘better than’, ‘worse than’, and ‘equally good’. It then explores two further questions: can parity be modeled by an interval representation of value? And what should one rationally do when faced with items on a par? I argue that an interval representation of value is incompatible with the possibility that items are on a par (a mathematical (...) proof is given in the appendix). I also suggest that there are three senses of ‘rationally permissible’ which, once distinguished, show that parity does distinctive practical work that cannot be done by the usual trichotomy of relations or by incomparability. In this way, we have an additional argument for parity from the workings of practical reason. (shrink)

A popular and plausible response against Laudan's “pessimistic induction” has been what I call “preservative realism,” which argues that there have actually been enough elements of scientific knowledge preserved through major theory‐change processes, and that those elements can be accepted realistically. This paper argues against preservative realism, in particular through a critical review of Psillos's argument concerning the case of the caloric theory of heat. Contrary to his argument, the historical record of the caloric theory reveals that beliefs about (...) the properties of material caloric, rejected by subsequent theories, were indeed central to the successes of the caloric theory. Therefore caloric remains a favorable case for Laudan. Further, I argue that even confirmed cases of preservation do not warrant an inference to truth. (shrink)

This paper is the introduction to the volume. It gives an argumentative view of the philosophical landscape concerning incommensurability and incomparability. It argues that incomparability, not incommensurability, is the important phenomenon on which philosophers should be focusing and that the arguments for the existence of incomparability are so far not compelling.

This encyclopedia entry urges what it takes to be correctives to common (mis)understandings concerning the phenomenon of incommensurability and incomparability and briefly outlines some of their philosophical upshots.

IT IS fairly well known that the problem of motion or, more generally, that of change is one of the oldest philosophical problems which can be traced to the very dawn of Western thought. It was inseparable from the basic problem which the Presocratics faced: that of the primary stuff underlying the phenomenal diversity of our sensory experience. Once the sensory diversity is viewed as merely apparent, one cannot avoid the question how such an appearance is generated by (...) the underlying single principle; in other words, one faces the problem of the origin of things, i.e., the problem of change. Hence the monism which in various forms underlies the majority of the early cosmogonic or protocosmogonic speculations. But already then three different theses are discernible: a) one rather extreme view which upholds rigorously the strict oneness of the underlying substance and from its immutability infers the impossibility of change; this was the view of Parmenides and his disciples; b) the second view which, while retaining the Eleatic principle of the singleness and immutability of the basic stuff, admits its existence in a plural form. This is atomism which reduces change to a change of position. In other words, diversity is retained only in the form of numerical diversity, and change only in the form of spatial displacement. All apparently qualitative changes are thus explainable in terms of combination and recombination of the homogeneous and immutable elements. Such are the basic premises not only of ancient Greek atomism, but very nearly of all forms of atomism in all different periods of history. Its basic inspiration has always remained Eleatic, although a very important concession has been made to sensory perception in the sense that the reality of change has been admitted. But it is admitted in its most innocuous form—in the form of displacement of the unchanging units of Being. (shrink)

This paper argues that there is a particular kind of ‘internal’ commitment typically made in the context of romantic love relationships that has striking meta-normative implications for how we understand the role of the will in practical normativity. Internal commitments cannot plausibly explain the reasons we have in committed relationships on the usual model – as triggering reasons that are already there, in the way that making a promise triggers a reason via a pre-existing norm of the form ‘If you (...) make a promise to x, then you have a reason to x’. Instead, internal commitments are that in virtue of which one has the special reasons of committed relationships; they are the grounds of such reasons. In this way, the will is a source of practical normativity. (shrink)

This book contains an introduction to symbolic logic and a thorough discussion of mechanical theorem proving and its applications. The book consists of three major parts. Chapters 2 and 3 constitute an introduction to symbolic logic. Chapters 4–9 introduce several techniques in mechanical theorem proving, and Chapters 10 an 11 show how theorem proving can be applied to various areas such as question answering, problem solving, program analysis, and program synthesis.
