Leibniz’s and Whitehead’s analyses of motion are at the heart of their metaphysical schemes. These schemes are to be considered as two blueprints of a similar metaphysical intuition that emerged during two breakthrough eras, that is, the 17th century and the beginning of the 20th century, and retained the Aristotelian idea that existence requires an active principle. The two philosophers’ attempts to elucidate this idea in the context of their analyses of motion still interact with central, longstanding questions in philosophy, (...) in particular that concerning the ontological status of change. For both thinkers, the phenomenon of motion is an example par excellence, of the metaphysically fundamental principle of action that is required for change in the world. I focus on Leibniz’s and Whitehead’s similar understanding of the concept of transition that is inserted as an essential constitutive component of motion and ensures its status as something real.Keywords: Gottfried Leibniz; Alfred Whitehead; Motion; Change; Relativity; Transition.

This paper examines the role that Leibniz’s philosophy played in the debate between the Idealists and their opponents at the turn of the twentieth century. While it is Russell’s The Philosophy of Leibniz which is most frequently referred to in this context, this paper focuses on John Dewey’s Leibniz’s New Essays which was written twelve years earlier, during the Hegelian phase of Dewey’s career. It is important to shift our attention to Dewey’s commentary not only because it has been almost (...) entirely neglected, but also because it provides a broader perspective on the role of the Leibnizian system in one of the leading debates in the history of philosophy, namely the debate over the intelligibility of the idea of internal relations. In particular, Dewey’s book reveals Leibniz’s involvement in the emergence of the notion of organism which was at the heart of the debate. (shrink)

In his Essays on the Intellectual Powers of Man Thomas Reid draws an analogy between his notion of the self and Leibniz’s notion of a monad. Reid formulates this analogy in order to highlight what he considers to be the essential feature of the self: its unified and indivisible structure. This paper considers Reid’s analogy in the specific context of the diachronic aspect of substantial unity. Its focus is specifically on the role that the idea of continuity plays in establishing (...) the unity and indivisibility of the entities in question (viz., the self and the monad). As part of the ongoing debate over Leibniz’s mature metaphysics of substance, this paper highlights the positive implication of Reid’s analysis of the self (usually viewed as a critical reaction to Locke and Hume) and its place within the early modern debate over the nature of substantial unity.

The goal in this article is to compare Bergson’s and Whitehead’s treatment of language and in particular the extent to which each believed that language is capable of expressing the temporal dimension of experience.

This paper offers a new look at Whitehead’s criticism of Leibniz’s metaphysics and at the role this criticism plays in the broader context of Whitehead’s philosophy. A re-evaluation of Whitehead’s reading is called for since he takes his own system as an elaboration of the Leibnizian one, and as an effort to overcome what he deemed its major difficulties. Whitehead’s alternative, which is formulated in terms of real connectivity among basic constituents, is aimed at solving what he takes to be (...) the most problematic issue within Leibniz’s system, namely, the analysis of phenomenal continuity. However, I claim that Whitehead’s criticism obscures the fact that he is much closer to Leibniz than he is willing to admit. (shrink)

We argue in this paper that Leibniz’s characterization of a substance as “un être” in his correspondence with Arnauld stresses the per se unity of substance rather than oneness in number. We employ two central lines of reasoning. The first is a response to Mogens Lærke’s claim that one can mark the difference between Spinoza and Leibniz by observing that, while Spinoza’s notion of substance is essentially non-numerical, Leibniz’s view of substance is numerical. We argue that Leibniz, like Spinoza, qualifies (...) the substance as “one” primarily in a non-numerical sense, where non-numerical means per se unity or qualitative uniqueness. The second line of reasoning suggests that the term “one” should be understood as a-unity-presupposed-by-multiplicity in two senses: a) externally, in the sense of being presupposed by higher complex structures, such as aggregates, and, b) internally, in the sense of having itself a complex structure. We develop an analogy along these lines between the role the notion of a fundamental unity plays in Leibniz’s view of numbers and his view of substance. In other words, we suggest that looking at the role units play in Leibniz’s view of mathematics can shed some light on the role they play in his metaphysics. (shrink)

On one standard reading, Plato's works contain at least two distinct views about the structure of the human soul. According to the first, there is a crucial unity to human psychology: there is a dominant faculty that is capable of controlling attention and behaviour in a way that not only produces right action, but also ‘silences’ inclinations to the contrary—at least in idealized circumstances. According to the second, the human soul contains multiple autonomous parts, and although one of them, reason, (...) normatively dominates the others, it may fail to do so descriptively: even in the face of full, explicit, well‐reasoned, conscious awareness of the truth of a claim, a person may continue to feel residual inclinations towards disavowed, inappropriate and misguided experiences and courses of action. In this paper, I will argue that even the second of these views does not fully capture the ways in which reflective commitment fails to guide human action. Whereas the traditional multi‐part soul view is well suited to explaining phenomena that involve a cognitive conflict between our reflective attitudes and our non‐reflective endorsements, it falls short when we turn to the full array of human patterns of response, because it neglects a further source of challenge to reason's rule, namely, the mediation of associative and heuristic processes. These processes introduce complications for which the simple faculty psychology view cannot adequately account. Because they produce challenges to reason's rule that are phenomenologically invisible, traditional strategies for self‐regulation cannot be straightforwardly applied to their management. (shrink)

The capacity to represent things to ourselves as possible plays a crucial role both in everyday thinking and in philosophical reasoning; this volume offers much-needed philosophical illumination of conceivability, possibility, and the relations between them.

Over the last decade, iterated learning studies have provided compelling evidence for the claim that linguistic structure can emerge from non‐structured input, through the process of transmission. However, it is unclear whether individuals differ in their tendency to add structure, an issue with implications for understanding who are the agents of change. Here, we identify and test two contrasting predictions: The first sees learning as a pre‐requisite for structure addition, and predicts a positive correlation between learning accuracy and structure addition, (...) whereas the second maintains that it is those learners who struggle with learning and reproducing their input who add structure to it. This prediction is hard to test in standard iterated learning paradigms since each learner is exposed to a different input, and since structure and accuracy are computed using the same test items. Here, we test these contrasting predictions in two experiments using a one‐generation artificial language learning paradigm designed to provide independent measures of learning accuracy and structure addition. Adults (N = 48 in each study) were exposed to a semi‐regular language (with probabilistic structure) and had to learn it: Learning was assessed using seen items, whereas structure addition was calculated over unseen items. In both studies, we find a strong positive correlation between individuals' ability to learn the language and their tendency to add structure to it: Better learners also produced more structured languages. These findings suggest a strong link between learning and generalization. We discuss the implications of these findings for iterated language models and theories of language change more generally.

Feeling like doing something is not the same as deciding to do it. When you feel like doing something, you are still free to decide to do it or not. You are having an inclination to do it, but you are not thereby determined to do it. I call this the moment of drama. This book is about what you are faced with, in this moment. How should you relate to the inclinations you “have,” given that you are free to (...) “act on” them or not? To answer this question, we need an account of what sort of thing we are relating to, in this moment. But here we find a genuine philosophical problem. Our inclinations are forms of motivation, with respect to which we are distinctively passive. To be motivated is to be self-moved. But how can we be passive in relation to our own self-movement? Is our relation to our inclinations like that of rider to horse? Or is it like our relation to our own, spontaneous judgments or perceptions? I lay out three constraints on any theory of inclination, and I argue that familiar theories fail to meet them, because they make being inclined to φ‎ too similar or dissimilar to φ‎-ing. I then put forward the “inner animal” view, which holds that when you are merely inclined to act, the instinctive part of yourself is already active, while the rest of you is not. In this moment, your will is “at a crossroads.” You can humanize your inclination, or dehumanize yourself. (shrink)

New biotechnologies have propelled the question of what it means to be human - or posthuman - to the forefront of societal and scientific consideration. This volume provides an accessible, critical overview of the main approaches in the debate on posthumanism, and argues that they do not adequately address the question of what it means to be human in an age of biotechnology. Not because they belong to rival political camps, but because they are grounded in a humanist ontology that (...) presupposes a radical separation between human subjects and technological objects. The volume offers a comprehensive mapping of posthumanist discourse divided into four broad approaches-two humanist-based approaches: dystopic and liberal posthumanism, and two non-humanist approaches: radical and methodological posthumanism. The author compares and contrasts these models via an exploration of key issues, from human enhancement, to eugenics, to new configurations of biopower, questioning what role technology plays in defining the boundaries of the human, the subject and nature for each. Building on the contributions and limitations of radical and methodological posthumanism, the author develops a novel perspective, mediated posthumanism, that brings together insights in the philosophy of technology, the sociology of biomedicine, and Michel Foucault's work on ethical subject constitution. In this framework, technology is neither a neutral tool nor a force that alienates humanity from itself, but something that is always already part of the experience of being human, and subjectivity is viewed as an emergent property that is constantly being shaped and transformed by its engagements with biotechnologies. Mediated posthumanism becomes a tool for identifying novel ethical modes of human experience that are richer and more multifaceted than current posthumanist perspectives allow for. The book will be essential reading for students and scholars working on ethics and technology, philosophy of technology, poststructuralism, technology and the body, and medical ethics. (shrink)

The problem of imaginative resistance holds interest for aestheticians, literary theorists, ethicists, philosophers of mind, and epistemologists. We present a somewhat opinionated overview of the philosophical discussion to date. We begin by introducing the phenomenon of imaginative resistance. We then review existing responses to the problem, giving special attention to recent research directions. Finally, we consider the philosophical significance that imaginative resistance has—or, at least, is alleged to have—for issues in moral psychology, theories of cognitive architecture, and modal epistemology.

Say that space is ‘gunky’ if every part of space has a proper part. Traditional theories of gunk, dating back to the work of Whitehead in the early part of last century, modeled space in the Boolean algebra of regular closed subsets of Euclidean space. More recently a complaint was brought against that tradition in Arntzenius and Russell : Lebesgue measure is not even finitely additive over the algebra, and there is no countably additive measure on the algebra. Arntzenius advocated (...) modeling gunk in measure algebras instead—in particular, in the algebra of Borel subsets of Euclidean space, modulo sets of Lebesgue measure zero. But while this algebra carries a natural, countably additive measure, it has some unattractive topological features. In this paper, we show how to construct a model of gunk that has both nice rudimentary measure-theoretic and topological properties. We then show that in modeling gunk in this way we can distinguish between finite dimensions, and that nothing in lost in terms of our ability to identify points as locations in space. (shrink)

The aim of this article is to expand the diet of examples considered in philosophical discussions of imagination and pretense, and to offer some preliminary observations about what we might learn about the nature of imagination as a result. The article presents a number of cases involving imaginative contagion: cases where merely imagining or pretending that P has effects that we would expect only perceiving or believing that P to have. Examples are offered that involve visual imagery, motor imagery, fictional (...) emotions, and social priming. It is suggested that imaginative contagion is a more prevalent phenomenon than has typically been recognized. (shrink)

Since the outbreak of COVID-19, governments have turned their attention to digital contact tracing. In many countries, public debate has focused on the risks this technology poses to privacy, with advocates and experts sounding alarm bells about surveillance and mission creep reminiscent of the post 9/11 era. Yet, when Apple and Google launched their contact tracing API in April 2020, some of the world’s leading privacy experts applauded this initiative for its privacy-preserving technical specifications. In an interesting twist, the tech (...) giants came to be portrayed as greater champions of privacy than some democratic governments. This article proposes to view the Apple/Google API in terms of a broader phenomenon whereby tech corporations are encroaching into ever new spheres of social life. From this perspective, the advantage these actors have accrued in the sphere of the production of digital goods provides them with access to the spheres of health and medicine, and more worrisome, to the sphere of politics. These sphere transgressions raise numerous risks that are not captured by the focus on privacy harms. Namely, a crowding out of essential spherical expertise, new dependencies on corporate actors for the delivery of essential, public goods, the shaping of public policy by non-representative, private actors and ultimately, the accumulation of decision-making power across multiple spheres. While privacy is certainly an important value, its centrality in the debate on digital contact tracing may blind us to these broader societal harms and unwittingly pave the way for ever more sphere transgressions.

I introduce and argue for the importance of a cognitive state that I call alief. An alief is, to a reasonable approximation, an innate or habitual propensity to respond to an apparent stimulus in a particular way. Recognizing the role that alief plays in our cognitive repertoire provides a framework for understanding reactions that are governed by nonconscious or automatic mechanisms, which in turn brings into proper relief the role played by reactions that are subject to conscious regulation and deliberate (...) control.

Through careful analysis of a specific example, Parfit’s ‘fission argument’ for the unimportance of personal identity, I argue that our judgements concerning imaginary scenarios are likely to be unreliable when the scenarios involve disruptions of certain contingent correlations. Parfit’s argument depends on our hypothesizing away a number of facts which play a central role in our understanding and employment of the very concept under investigation; as a result, it fails to establish what Parfit claims, namely, that identity is not what (...) matters. I argue that Parfit’s conclusion can be blocked without denying that he has presented an imaginary case where prudential concern would be rational in the absence of identity. My analysis depends on the recognition that the features that explain or justify a relation may be distinct from the features that underpin it as necessary conditions. (shrink)

I propose that paradigmatic cases of self-deception satisfy the following conditions: (a) the person who is self-deceived about not-P pretends (in the sense of makes-believe or imagines or fantasizes) that not-P is the case, often while believing that P is the case and not believing that not-P is the case; (b) the pretense that not-P largely plays the role normally played by belief in terms of (i) introspective vivacity and (ii) motivation of action in a wide range of circumstances. Understanding (...) self-deception in this way is highly natural. And it provides a non-paradoxical characterization of the phenomenon that explains both its distinctive patterns of instability and its ordinary association with irrationality. Why, then, has this diagnosis been overlooked? I suggest that the oversight is due to a failure to recognize the philosophical significance of a crucial fact about the human mind, namely, the degree to which attitudes other than belief often play a central role in our mental and practical lives, both by "influenc[ing our]... passions and imagination," and by "governing.. .our actions.".

The Human Animal is an extended defense of what its author calls the Biological Approach to personal identity: that you and I are human animals, and that the identity conditions under which we endure are those which apply to us as biological organisms. The somewhat surprising corollary of this view is that no sort of psychological continuity is either necessary or sufficient for a human animal—and thus for us—to persist through time. In challenging the hegemony of Psychological Approaches to personal (...) identity, Olson offers a number of inventive and original arguments which are certain to evoke discussion and debate.

In this paper I try to undermine complacency with a predominant conception of desire, for the sake of refocusing attention on a philosophical problem. The predominant conception holds that to have a desire is to occupy an evaluative outlook, a perspective from which the agent 'sees' the world in practically salient terms. I argue that it is not clear what this theory is a theory of, because the concept of desire at its center is deeply ambiguous. Understood as a theory (...) of desire in what I call the "placeholder" sense, the evaluative outlook theory is at bottom a theory of action explanation. So construed, its claim is relatively uncontroversial, and falls far short of being a full theory of action explanation. Understood as a theory of desire in what I call the "substantive" sense, it does not even go so far as to acknowledge the central problem such a theory has to answer. That problem is how we can be passive (in a particular sense) with respect to our own motivation. (shrink)

Perhaps the concept of knowledge, prior to its being fashioned and molded by certain philosophical traditions, never offered any stable negative verdict in the original fake barn case.

To imagine is to form a mental representation that does not aim at things as they actually, presently, and subjectively are. One can use imagination to represent possibilities other than the actual, to represent times other than the present, and to represent perspectives other than one’s own. Unlike perceiving and believing, imagining something does not require one to consider that something to be the case. Unlike desiring or anticipating, imagining something does not require one to wish or expect that something (...) to be the case. // -/- Imagination is involved in a wide variety of human activities, and has been explored from a wide range of philosophical perspectives. Philosophers of mind have examined imagination’s role in mindreading and in pretense. Philosophical aestheticians have examined imagination’s role in creating and in engaging with different types of artworks. Epistemologists have examined imagination’s role in theoretical thought experiments and in practical decision-making. Philosophers of language have examined imagination’s role in irony and metaphor. // -/- Because of the breadth of the topic, this entry focuses exclusively on contemporary discussions of imagination in the Anglo-American philosophical tradition.

Antibiotic resistance poses an urgent public health risk. High rates of ABR have been noted in all regions of the globe by the World Health Organization. ABR develops when bacteria are exposed to antibiotics either during treatments in humans or animals or through environmental sources contaminated with antibiotic residues. Spread beyond those administered antibiotics occurs through direct contact with the infected or colonized person or animal, through contact or ingestion of retail meat or agricultural products contaminated with ABR organisms, or (...) through the environment. ABR bacteria spread from individuals to populations and across countries. (shrink)

Este artículo pretende constituir una breve reflexión crítica sobre los usos políticos de la violencia masculina sobre las mujeres, y de cómo, por tanto, una cuestión indudablemente fundamental, enfatizada por los movimientos de las mujeres y tratada por mucha literatura de inclinación feminista, puede ser utilizada dentro de un marco de referencia que se presta a legitimar políticas de seguridad, más que a facilitar el hallazgo de una respuesta adecuada al problema. Me ayudaré de ejemplos extraídos de lo que ocurre (...) en Italia, aunque es sabido que esta instrumentalización es común en muchos otros contextos culturales y políticos, y que es coherente con una modalidad de gobierno hoy hegemónica, el neoliberalismo. Mi tesis def iende que este uso ha sido facilitado por el colapso, tanto lingüístico como cultural, de toda la temática que tiene que ver con la relación asimétrica entre los sexos en el ámbito de la “violencia”. Este colapso, a su vez, puede interpretarse, desde mi punto de vista, como uno de los productos del avance de la hegemonía de la racionalidad política neoliberal durante los últimos treinta años.

It is of great use to the sailor to know the length of his line, though he cannot with it fathom all the depths of the ocean.

By carefully examining one of the most famous thought experiments in the history of science—that by which Galileo is said to have refuted the Aristotelian theory that heavier bodies fall faster than lighter ones—I attempt to show that thought experiments play a distinctive role in scientific inquiry. Reasoning about particular entities within the context of an imaginary scenario can lead to rationally justified concluusions that—given the same initial information—would not be rationally justifiable on the basis of a straightforward argument.

"Expanding the Palace of Torah" offers a broad philosophical overview of the challenges the women's revolution poses to Orthodox Judaism, and Orthodox Judaism's response to those challenges.

This book offers a novel analysis of the widely-used but ill-understood technique of thought experiment. The author argues that the powers and limits of this methodology can be traced to the fact that when the contemplation of an imaginary scenario brings us to new knowledge, it does so by forcing us to make sense of exceptional cases.

Contemplating imaginary scenarios that evoke certain sorts of quasi‐sensory intuitions may bring us to new beliefs about contingent features of the natural world. These beliefs may be produced quasi‐observationally; the presence of a mental image may play a crucial cognitive role in the formation of the belief in question. And this albeit fallible quasi‐observational belief‐forming mechanism may, in certain contexts, be sufficiently reliable to count as a source of justification. This sheds light on the central puzzle surrounding scientific thought experiment, (...) which is how contemplation of an imaginary scenario can lead to new knowledge about contingent features of the natural world.

It is a commonplace that contemplation of an imaginary particular may have cognitive and motivational effects that differ from those evoked by an abstract description of an otherwise similar state of affairs. In his Treatise on Human Nature, Hume ([1739] 1978) writes forcefully of this.

There is a puzzle in the very notion of passive motivation ("passion" or "inclination"). To be motivated is not simply to be moved from the outside. Motivation is in some sense self-movement. But how can an agent be passive with respect to her own motivation? How is passive motivation possible? In this paper I defend the ancient view that inclination stems from a motivational source independent of reason, a motivational source that is both agential and nonrational.
