이 글은 데카르트의 수동적 물체론과 운동학에서의 힘 개념을 웨스트폴과 하트필드의 대립적인 해석과 함께 논구해보고자 한다. 웨스트폴은 데카르트의 물체론에 동역학적인 요소가 있다고 보았으며, 그로 인해 데카르트의 물체론이 모순에 빠진다고 비판하였다. 이에 대해 하트필드는 데카르트의 물체론은 그의 형이상학과 함께 이해되어야 한다고 보았으며, 이러한 관점을 가지지 못한 웨스트폴을 비판하였다. 하트필드에 따르면, 웨스트폴은 데카르트의 형이상학보다 자연학과 운동 법칙 자체를 더 중점적으로 생각했고, 그럼으로써 데카르트의 물체론을 데카르트의 전체 체계 내에서 통합적으로 사유하지 못했다. 이 글은 하트필드의 입장을 지지하며 데카르트의 수동적 물체론이 내포한 형이상학적 기초를 확인함으로써, 데카르트의 (...) 물체론과 형이상학을 함께 사유하는 것의 의의를 확인하고자 한다. 이는 갈등론적 관점에서 한 이론에 대한 두 대립적인 해석이 빚는 갈등이 갖는 가치 또한 시사할 것이다.

The paper deals with the role of the concept of force in different classical mechanical and field theories, pointing out the existence in all cases of a Lorentz-type expression for force. In the case of the classical theory of the gravitational field we obtain the same Lorentz-type expression.

A survey of the various meanings assumed by the concept of force in physics and philosophy from ancient times to the present. Seldom rising above the level of description to the level of historical understanding, it is informative rather than illuminating and, though scholarly, unimaginatively written. -- C. L.

Both historical treatment and critical analysis, this work by a noted physicist takes a fascinating look at a fundamental of physics, tracing its development from ancient to modern times.

This dissertation examines Kant's transcendental idealism with respect to his account of natural forces. Although force plays a crucial role in Kant's pre-critical writings, especially in his argument against Leibniz's pre-established harmony, it is conspicuously absent in the Critique of Pure Reason . I argue that force has to be excluded once Kant's philosophy takes its "critical turn" in order for his transcendental argument to be able to prove that the categories of thought apply to objects of experience. (...) In order for the forms of thought to apply to the matter of sensibility, both thought and sensible intuition must not only be forms of unity, or unified forms, but also uniform in quality and capable of being measured in terms of extensive magnitudes. Force, on the other hand, is an intensive magnitude which is measured not in terms of homogeneous units, but in terms of degrees. It must be excluded from Kant's critical philosophy since the coherence of the experience that Kant seeks to justify requires the uniformity and consistency of the subject, the ground of knowledge. Nevertheless, the concept of force can still be found to be "at work" in the Critique of Pure Reason in Kant's schematism of the categories of quality and the principle of the anticipations of perception which are based on this schematism. In order for a quality to be predicated of an object it must have an impact on the subject and become an object of attention. Kant's controversial discussion of judgments of perception in the Prolegomena, can be understood as his attempt to incorporate force into his ontology by introducing a new category of thought, that of analogy. In the case of analogy, I argue, the copula of the judgment is not that of being but is that of force itself. This form of judgment ultimately becomes the reflective judgment in Kant's Critique of Judgment, which makes explicit the form of thought that would make the experience of force possible. (shrink)

Newton’s physics is based on two fundamental concepts: mass and force. In the _Principia_ Newton explores the propoerties of several types of force. The most important of these are forces that produce accelerations or changes in the state of motion or of rest of bodies. In Definition 4 of the Principia, Newton separates these into three principal categories: impact or percussion, pressure, and centripetal force. In the Principia, Nwton mentions other types of forces, including (in Book (...) 2) the forces with which fluids resist motions through them. Of a different sort is Newton’s „force of inertia“, which is neither an accelerative force nor a static force and is nit, properly speaking in the context of dynamics, a force at all. (shrink)

Although the momentum metaphor is successful in many ways, there remain problems with the adequacy of the notion of a force in the behavioral sense and the question of whether the conditions used to apply force can truly be separated from the conditions that establish and maintain behavioral mass.

This article aims to contribute to the literature on conceptual change by engaging in direct theoretical and empirical comparison of contrasting views. We take up the question of whether naïve physical ideas are coherent or fragmented, building specifically on recent work supporting claims of coherence with respect to the concept of force by Ioannides and Vosniadou [Ioannides, C., & Vosniadou, C. (2002). The changing meanings of force. Cognitive Science Quarterly 2, 5–61]. We first engage in a theoretical inquiry (...) on the nature of coherence and fragmentation, concluding that these terms are not well‐defined, and proposing a set of issues that may be better specified. The issues have to do with contextuality, which concerns the range of contexts in which a concept (meaning, model, theory) applies, and relational structure, which is how elements of a concept (meaning, model, or theory) relate to one another. We further propose an enhanced theoretical and empirical accountability for what and how much one needs to say in order to have specified a concept. Vague specification of the meaning of a concept can lead to many kinds of difficulties.Empirically, we conducted two studies. A study patterned closely on Ioannides and Vosniadou's work (which we call a quasi‐replication) failed to confirm their operationalizations of “coherent.” An extension study, based on a more encompassing specification of the concept of force, showed three kinds of results: (1) Subjects attend to more features than mentioned by Ioannides and Vosniadou, and they changed answers systematically based on these features; (2)We found substantial differences in the way subjects thought about the new contexts we asked about, which undermined claims for homogeneity within even the category of subjects (having one particular meaning associated with “force”) that best survived our quasi‐replication; (3) We found much reasoning of subjects about forces that cannot be accounted for by the meanings specified by Ioannides and Vosniadou. All in all, we argue that, with a greater attention to contextuality and with an appropriately broad specification of the meaning of a concept like force, Ioannides and Vosniadou's claims to have demonstrated coherence seem strongly undermined. Students' ideas are not random and chaotic; but neither are they simply described and strongly systematic. (shrink)

The objective of this chapter is to trace the influence of Stoic dispositional innatism on the early development of Herder’s concept of force through an examination of two of the most likely sources of transmission of this tradition: Leibniz and Shaftesbury. The interdependence of soul-forces, the obscure, and dispositional innatism is then explored in Herder’s plan for an aesthetics that genuinely comes to grips with the lower, sensuous regions of the soul that he presents against the backdrop of his (...) critical engagement with Baumgarten.

This article discusses the quest for the mechanical advantage of the wedge in the eighteenth century. As a case study, the wedge enlightens our understanding of eighteenth-century mechanics in general and the controversy over “force” or vis viva in particular. In this article, I show that the two different approaches to mechanics, the one that favoured force in terms of velocities and the one that primarily used displacements—known as the ‘Newtonian’ and ‘Leibnizian’ methods, respectively—were not at all on (...) par in their ability to solve the problem of the wedge. In general, only those who used the Leibnizian concept of force or some related notion were able to get to the conventional results. This article thus rebuts the received view that the vis viva controversy was merely a semantic one. Instead, it shows that different understandings of “force” led to real and pragmatic differences in eighteenth-century mechanics. (shrink)

The phenomenon of self-healing forces has again and again challenged doctors in the different historical periods of medical science. They relied on effects of self-healing forces in diagnosis and therapy. They also tried to explain these effects based on the current model of organism. The understanding of this phenomenon has always influenced the understanding of therapy and played a role in defining the concept of health and disease. In the 17th and 18th century the idea of self-healing force was (...) interpreted as a phenomenon related to the organic forces, whereas in the 19th century the explanation was reduced to a materialistic mechanism. Nowadays the knowledge of heath-shock-proteins open the way of a new understanding of the organic defense mechanisms. (shrink)

I argue that the key dynamical concepts and laws of Newton's Principia never gained a solid foothold in Germany before Kant in the 1750s. I explain this absence as due to Leibniz. Thus I make a case for a robust Leibnizian legacy for Enlightenment science, and I solve what Jonathan Israel called “a meaningful historical problem on its own,” viz. the slow and hesitant reception of Newton in pre-Kantian Germany.

In this paper I want to examine in some detail one eighteenth-century attempt to restructure the foundations of mechanics, that of Leonhard Euler. It is now generally recognized that the idea, due to Mach, that all that happened in the eighteenth century was the elaboration of a deductive and mathematical mechanics on the basis of Newton's Laws is misleading at best. Newton's Principia needed much more than a reformulation in analytic terms if it was to provide the basis for the (...) comprehensive mechanics that was developed in the eighteenth century. Book II of the Principia, in particular, where the problem of the resistance offered to the motion of a finite body by a fluid medium was raised, was generally thought to be in large part mistaken and confused. There were also a number of areas crucial to the unification of mechanics which Newton did not deal with at all in the Principia: particularly the dynamics of rigid, flexible and elastic bodies, and the dynamics of several bodies with mutual interactions. Although a start had been made on some of these topics in the seventeenth century , it was only in the eighteenth century that they were subjected to detailed examination, and Euler's contribution to the development of these topics, and hence to the unification of mechanics, was immense.

ABSTRACT The concept of vital force in African philosophy received its first full articulation in Placide Tempels’s Bantu Philosophy and has evolved over time from the ontological dimension of a universal actuation and energizing principle to an element of mind, notably in the work of Kwame Gyekye. In this essay, I present the concept of vital force and trace its evolution from the time of its first full articulation by Tempels up to its identification with spirit, or mind, (...) in Gyekye’s thought. I try to defend the thesis that the concept of vital force can ground the notion of mood that takes a pivotal position in the twenty-first century philosophy of consolationism. I adopt an analytical and constructive method in this paper. (shrink)

This paper explores Kant's account of force, a topic that was of central philosophical concern in his day, but which he does not explicitly address in any of his Critiques. Just as with the nature of space and time and the nature of the human will, the nature of force was under dispute by the philosophers and natural scientists to whose legacy Kant was responding. Yet, Kant does not make force an explicit topic of his Critiques, and (...) thus provides no explicit transcendental account of force. Nevertheless, I will argue that one can indeed find in Kant a transcendental account of force, one that is a synthesis of empiricist and rationalist accounts, but in an unexpected place; the third Critique, in the discussion of the principle of purposiveness.

The ability of international ethics and political theory to establish a genuinely critical standpoint from which to evaluate uses of armed force has been challenged by various lines of argument. On one, theorists question the narrow conception of violence on which analysis relies. Were they right, it would overturn two key assumptions: first, that violence is sufficiently distinctive to merit attention as a category separate from other modes of human harming; second, that it is troubling in a special way (...) that makes acts of violence peculiarly hard to justify. This paper defends a narrow understanding of violence and a special ethics governing its use by arguing that a distinctive form of ‘Violent Agency’ is the factor uniting the category while partly accounting for the fearful connotations of the term. Violent Agency is defined first by a double intention (1) to inflict harm using a technique chosen (2) to eliminate or evade the target’s means of escaping it or defending against it. Second, the harms it aims at are destructive (as opposed to appropriative). The analysis offered connects the concept of violence to themes in international theory such as vulnerability, security, and domination, as well as the ethics of war. (shrink)

The French philosopher and intellectual historian Pierre Hadot (1922-2010) is known primarily for his conception of philosophy as spiritual exercise, which was an essential reference for the later Foucault. An aspect of his work that has received less attention is a set of methodological reflections on intellectual history and on the relationship between philosophy and history. Hadot was trained initially as a philosopher and was interested in existentialism as well as in the convergence between philosophy and poetry. Yet he chose (...) to become a historian of philosophy and produced extensive philological work on neo-Platonism and ancient philosophy in general. He found a philosophical rationale for this shift in his encounter with Wittgenstein's philosophy in the mid-1950s (Hadot was one of Wittgenstein's earliest French readers and interpreters). For Hadot, ancient philosophy must be understood as a series of language games, and each language game must be situated within the concrete conditions in which it happened. The reference to Wittgenstein therefore supports a strongly contextualist and historicist stance. It also supports its exact opposite: presentist appropriations of ancient texts are entirely legitimate, and they are the only way ancient philosophy can be existentially meaningful to us. Hadot addresses the contradiction by embracing it fully and claiming that his own practice aims at a coincidence of opposites (a concept borrowed from the Heraclitean tradition). For Hadot the fullest and truest way of doing philosophy is to be a philosopher and a historian at the same time. (shrink)

The literature on Dreams of a Spirit-Seer typically emphasises the ways that Kant’s complex 1766 work prefigures his critical turn. Kant indeed criticises Wolffian «dreamers of reason» and defines metaphysics as a «science of the limits of human reason». It has not been noted, however, that Kant’s first restriction on human knowledge in Dreams is targeted at knowledge of fundamental physical forces. Moreover, Kant criticises the ‘pneumatological’ laws of mental forces, insisting that these cannot be known through analogy with physical (...) forces. This paper presents the historical context of Kant’s claims and argues that his critique of the philosophical concept of force (Kraft) is primarily in dialogue with one of Wolff’s most renowned critics, Crusius. On this basis, I contend that Kant’s examination of our capacity to know fundamental physical and mental forces is an important aspect of his early critique of metaphysics. I defend my account by contrasting it with Alison Laywine’s interpretation. (shrink)

Evolutionary epistemology has experienced a continuous rise over the last decades. Important new theoretical considerations and novel empirical findings have been integrated into the existing framework. In this paper, I would like to suggest three lines of research that I believe will significantly contribute to further advance EE: ontogenetic considerations, key ideas from cognitive biology, and the framework of the Extended Evolutionary Synthesis. EE, in particular the program of the evolution of epistemological mechanisms, seeks to provide a phylogenetic account of (...) the generation of cognitive processes underlying knowledge creation. Traditionally, EE and EEM have been oriented towards an account of evolutionary theory that mainly drew from the tenets of the Modern Synthesis. The Modern Synthesis largely dismisses ontogenetic processes and considers them irrelevant for evolutionary explanations. If anything, the role of development in evolution is believed to be that of a constraint. There is, however, ample evidence for a tight intertwinement of developmental and evolutionary processes. Organisms employ their cognitive apparatus to interact with the environment in order to achieve a fully functioning perceptual and cognitive nervous system. Also, ontogeny provides generative potentials to enable variations that natural selection can act upon. EEM’s agenda may, therefore, strongly benefit from bringing together ontogenetic and phylogenetic approaches. To grapple with this challenge, an alternative vision of the evolutionary theory termed Extended Evolutionary Synthesis could be used. This extended evolutionary theory explores relationships between the processes of individual development and phenotypic change during evolution and can provide a more suitable framework for EEM to draw from. In recent years, cognitive biology has gained momentum as an independent research field. Cognitive biology builds on the concepts of EEM and understands knowledge as a biogenic phenomenon. Its main objective is also the formulation of substantiated interrelations between cognition and evolution but it focuses on cognitive functionality at all levels of biological organization. It thus employs a “vertical” approach that encompasses nested hierarchies which span from single molecules, cells, and tissues to the organismal level, communities, and societies. In contrast to cognitive biology, EEM is here understood to adopt a “horizontal” approach that focuses on phylogenetic explanations of cognition and knowledge acquisition. Linking EEM with the key ideas of cognitive biology could make EEM’s research program stronger as it can more easily accommodate phylogenetic and ontogenetic questions within a hierarchical, multilevel perspective. This is of particular importance for a more comprehensive account of cognition since living systems are subject to context-dependent causal influences from different organizational levels. In addition to EEM, there is a second program of EE. This program has been labeled evolutionary epistemology of theories and understands the increase in human knowledge, such as scientific theories, as naturalistic accounts of evolution. Both, EEM and EET initially drew from the core concepts of the Modern Synthesis. Several scholars have severely criticized the analogies made between EET and the Neo-Darwinian key processes of evolution. In particular processes of random mutation, the rate of variation, natural selection as the unique driving force, and the adaptationist agenda are believed to reveal disanalogies. In contrast to the Modern Synthesis, the Extended Evolutionary Synthesis not only recognizes developmental processes but also ecological interactions and systems dynamics as well as social and cultural evolutionary reciprocity as important evolutionary processes. Concepts of the Extended Evolutionary Synthesis are therefore expected to be more fruitful for re-conceptualizing parallels between scientific theorizing and biological evolution. (shrink)

Concepts of stability and symmetry in irreversible thermodynamics are developed through the analysis of system energy flows. The excess power function, derived from a local energy conservation equation, is shown to yield necessary and sufficient stability criteria for linear and nonlinear irreversible processes. In the absence of symmetry-destroying external forces, the linear range may be characterized by a set of phenomenological coefficient symmetries relating coupled forces and displacements, velocities, and accelerations, whereas rotational phenomena in nonlinear processes may be characterized (...) by skew-symmetric components of the phenomenological coefficients. A physical interpretation of the nature of the skew-symmetric parts is given and the variational principle of minimum dissipation of energy is related to a stability criterion. (shrink)

What is the status and nature of the “it” and the ontological progression from an “it” to an “it” in Ifeanyi Menkiti’s normative conception of a person? In this article, I attempt to preliminarily give some nuance content to the “it” of childhood and the “it” of the nameless dead. My motivation is straightforwardly simple: to defend Menkiti’s claim that both “its” have some depersonalised moral standing or existence. However, in doing so, I argue that a better account of the (...) ontological progression of personhood is from an “it” to an “it-it” 1 rather than from an “it” to an “it.” On this modified version of the double hyphenated “its”, which is underpinned by the idea of moral force, the prior moral worth of the nameless dead is taken into account as valuable members of our collective immortality, notwithstanding the fact that their names have been forgotten. Keywords: African Philosophy, Collective Immortality, Menkiti, It, It-it, Moral Force, Nameless Dead, Personhood. (shrink)

This article explores and seeks to appropriate theologically the African notion of vital force as a relational, non-reductionist ecological concept that would enrich the Christian doctrine of pneumatheology. The understanding that relational and pneumatological categories are viable within the theology–science dialogue is the broader framework within which this article is conceived. The relationship between natural theology and revelation provides an epistemological standpoint that does not divorce Spirit and reality.

Maimonides (1135/1138–1204) and Zhu Xi 朱熹 (1130–1200) are unparalleled in the transformation and revitalization of Jewish and Confucian traditions, respectively. This article offers a comparative analysis of the two philosophers’ conceptions of nature and their view on the end of knowledge. It examines, on one hand, Maimonides’s distinctive interpretation of the rabbinic concept of maʿaseh bereshith (the Account of the Beginning) in the light of his statement that maʿaseh bereshith is identical with natural science; and on the other hand, Zhu (...) Xi’s elucidation of key concepts such as xing 性 (nature), shu 數 (number), tian 天 (heaven), and cheng 誠 (genuineness) in the framework of his doctrine of li 理 (pattern or principle) and qi 氣 (material force). The article points out that Maimonides not only connects the maʿaseh bereshith to the beginning of the world, as traditionally held; he also associates it with the beginning of the revelation of the Mosaic Law, which renders profound implications. While both emphasize the inherent nature of all things, they diverge on the ultimate goal of knowledge in terms of the hierarchy of virtues. Along with Aristotle, Maimonides prioritizes rational virtue over moral virtue, thereby placing intellectual perfection as the ultimate human perfection. In contrast, Zhu Xi esteems knowledge of nature as facilitating the pursuit of the highest goal of sagehood, and leaves no room for the higher status of theoretical pursuit to moral cultivation.

Theorizing of forced migration and refugees has been paralyzed by excessive reliance on migration theory. This article suggests the need to transfer conceptualizations of forced migration to sociological theories of violence. To that end, a preliminary step is argued to be indispensable: the affirmation of the force factor as a vital concept for meaningful theorization of refugee phenomena. Conceptual and empirical reasons are offered to resurrect the force factor’s centrality. First, I suggest the need to resolve the conceptual (...) residuality of “forced migration” in sociological theory, proposing manageable terminology for the task at hand. Second, I sketch conceptual and empirical reasons that the force factor is a viable and urgent candidate for our theoretical toolkit. Finally, I assess in depth the shortcomings of three prominent relativization conditions: (1) unwitting severity; (2) processual dilution; and (3) political-economic indeterminacy. By overcoming onerous relativization habits, we open horizons for coercion-centric theoretical insights on forced migration. (shrink)
