In 1792 and 1798 Kant noticed two basic problems with hisMetaphysical Foundations of Natural Science (MAdN) which opened a crucial gap in the Critical system as a whole. Why is theMAdN so important? I show that the Analogies of Experience form an integrated proof of transeunt causality. This is central to Kant's answer to Hume. This proof requires explicating the empirical concept of matter as the moveable in space, it requires the specifically metaphysical principle that every physical event has an (...) external cause, and it requires a metaphysical principle regarding the individuation of spatio-temporal things. These three doctrines are not defended in the firstCritique, but only in theMAdN. Kant's transcendental analysis of the conditions of experience thus requires the special metaphysics of theMAdN. This marks an important shift in Kant's view of the metaphysical basis of the transcendental philosophy. (shrink)

Transcendental philosophy was not born like Athena out of Zeus’s head, mature and in full armour from the very beginning. That is why in both prefaces to the Critique of Pure Reason (1781 and 1787) Kant introduces the concept of transcendental philosophy as an “idea.” The idea understood architectonically develops slowly and only gradually acquires a definite form. As witnessed by the works of Kant himself and of his predecessors and followers, the idea of transcendental philosophy has undergone a series (...) of changes and adjustments compared to the initial plan. In this context, my goal is not simply exegesis and historical investigation of transcendental philosophy, but also to look at it from a systematic and methodological perspective. I examine the concept of transcendental philosophy from the viewpoint of programmatic metaphilosophy. The first part discusses programmatics as a distinct subsection of metaphilosophy. I argue that Kant’s architectonic methodology and the methodology of Lakatos can be used to understand the inception, development and degradation of philosophical systems. In the second part I look at the project of transcendental philosophy and the stages of its development from the standpoint of architectonics. The third part shows that Lakatos’s methodology can provide a detailed insight into the elements of transcendental philosophy, a clear idea of its logic and identify the component parts that can be improved and developed. In spite of the different levels of detailing and epistemological prerequisites, the methodologies of Kant and Lakatos can be combined to achieve a metaphilosophically informed and progressive understanding of philosophical projects.

Se trata de pensar y abrir el horizonte del ser-con desde los análisis fenomenológicos vertidospor Heidegger en la I Sección de su libro Ser y Tiempo, respetando y aceptando sus propiaslimitaciones intrínsecas y a pesar del carácter aparentemente negativo que rodea a este existenciario,a fin de radicalizarlo, extenderlo y ubicarlo en su posibilidad más genuina. Por esta razón, a través deuna interpretación de corte fenomenológico, se ha querido potenciar los posibles rendimientos de unser-con en propiedad, enfatizando la necesidad de interpretar (...) el opus magnum heideggeriano desdeel horizonte de la mismidad del Dasein. La conclusión apunta sobre dos vías temáticas, a saber: a) atomar la mismidad del Dasein, por cuanto constituye una posibilidad ejecutiva de existir conforme alo que este ente es, en tanto condición necesaria y suficiente para pensar un ser-con en propiedad; b) aestablecer, casi a modo de esbozo, una relación entre ser-con, libertad y mismidad, la cual tiene su basetemática en una presumible igualdad de orden pre-ontológico.

This work examines Kant’s remarkable decision to rewrite the core argument of the first Critique, the Transcendental Deduction of the Categories. I identify a two-part structure common to both versions: first establishing an essential role for the categories in unifying sensible intuitions; and then addressing a worry about how the connection between our faculties asserted in the first part is possible. I employ this structure to show how Kant rewrote the argument, focusing on Kant’s response to the concerns raised in (...) an early review by Johann Schultz. Schultz’s dissatisfaction with the original Deduction lies in its second part, and Kant’s subsequent revisions are focused on providing a better answer to this how-possible question. The new Deduction offers a more direct and convincing account of how our faculties work together to make experience possible. (shrink)

O objetivo do presente artigo é fazer uma exposição sumária dos resultados obtidos em minha tese de doutorado, defendida e aprovada no Instituto de Filosofia e Ciências Humanas da Unicamp no dia 09 de junho de 2015. Assim, se apresenta resumidamente a discussão sobre a necessidade dos chamados “fins morais da razão” dentro da filosofia kantiana. Tal investigação propunha explicitar algumas modificações apresentadas na ética de Kant dos textos da década de 1780 aos seus textos tardios da segunda metade da (...) década de 1790, mostrando que elas vão no sentido de uma sensificação da ética kantiana e que esta só é possível à medida que Kant substitui conceitos de origem cristã notadamente comprometidos com um domínio da transcendênciapor conceitos de origem grega mais ligados ou mais passíveis de serem vinculados à natureza humana.

This thesis aims to throw an illuminating light on the as yet neglected concept of nothing in Kant’s system, a concept which is taken into consideration, by Kant, in accordance with the guiding thread of the categories of the understanding. My main argument is that Kant has a fourfold division of nothing and each has a transcendental function in his system. This function is basically a limiting one; setting up negative determinations without which Kant’s system would have never been constituted (...) as it is now. It is shown in the thesis that the concept of nothing is divided basically into four: first, nothing as ens rationis that limits and thereby protects knowledge, secondly nothing as nihil privativum that defines the boundaries of phenomenal reality, thirdly nothing as ens imaginarium that makes possible the unity of experience and finally, nothing as nihil negativum that draws the lines of logical thinking. All make, in the last resort and by being the concepts of the opposite, experience possible. The thesis consists of four chapters. The first chapter is an exposition of all four divisions of nothing, the second is the display specifically of the concepts of ens rationis and nihil negativum, and the third is of the concepts of ens imaginarium and nihil privativum. The auxiliary argument of the thesis is that while Hegel makes a strong charge of externality against and thereby severely criticizes the Kantian concept of the thing-in-itself, - the concept of which I propose to be contained under the concept of ens rationis- Kant has equally convincing arguments against such a charge. This is the topic of the fourth and final chapter which has an implicit aim of creating the image of a powerful critical Hegel but on the other hand an equally enduring and war-like Kant. Kant is presented as a philosopher who has powerful responses to institute a balance between himself and his opponent. When Kant’s differing concepts of nothing are taken into account, Hegel’s attack of externality, it is maintained, appears not to have taken into account the full measure of the resources of the Kantian position. Even when it is said that the attack is against one specific concept of the thing-in-itself alone, Kant still seems to have enough resources for toleration and defence indeed. (shrink)

La Reflexión de Leningrado, desde su publicación en 1986, ha llamado la atención principalmente por la introducción de la apercepción cosmológica, cuya función en el sistema kantiano no es del todo clara. Usualmente, la interpretación del concepto ha sido condicionada por la lectura de la Reflexión como una modificación de la Refutación del Idealismo, de lo que es buen ejemplo el trabajo de Claudia Jáuregui. En este ensayo, argumento que esta lectura no puede dar cuenta de todas las innovaciones a (...) las que Kant parece estar apuntando en este texto y que, por el contrario, relacionarlo con ciertos avances en el Opus Postumum con respecto a la auto-afección lleva no sólo a una comprensión más rica de la apercepción cosmológica, sino también a un argumento innovador frente al idealismo.

In a recent paper, Pierluigi Barrotta argues that Mises ‘ended up by defending an epistemological tenet very far from Kant's’, concluding that ‘Mises's apriorism cannot be vindicated through Kant's epistemology’. In contrast, I shall argue that certain of Mises's arguments can be reconstructed in Kantian terms, and thus the distance between Mises and Kant is not as extreme as Barrotta's argument may appear to suggest. Specifically, I shall argue that Mises, like Kant, seeks to establish the a priori nature of (...) the category of causality. To this extent at least, Mises's apriorism can be vindicated through Kant's epistemology. (shrink)

In his Metaphysische Anfangsgründe der Naturwissenschaft (MAN), Kant claims that chemistry is an improper, though rational science. The chemistry to which Kant confers this status is the phlogistic chemistry of, for instance, Georg Stahl. In his Opus Postumum (OP), however, Kant espouses a broadly Lavoiserian conception of chemistry. In particular, Kant endorses Antoine Lavoisier's elements, oxygen theory of combustion, and role for the caloric. As Lavoisier's lasting contribution to chemistry, according to some histories of the science, was his emphasis on (...) quantitative methods, Kant's assimilation of the chemical revolution raises the question: did Kant continue to think of chemistry as an improper, though rational, science in OP? In this paper, I answer this question affirmatively. I explain that a proper science requires a priori laws for the mathematical construction of its objects: the mere use of quantitative measurements is insufficient for the satisfaction this requirement. Further, I argue, contra Burkhard Tuschling, that in OP Kant retains a central role for mathematical construction in the foundations of proper natural science. Finally, I contend that the prominent a priori components of chemistry discussed in OP—the aether and the enumeration of the elements—do not make chemistry into a proper science. (shrink)

On 11thOctober 2007, at the first international conference on Integrated History and Philosophy of Science (&HPS1) hosted by the Center for Philosophy of Science in Pittsburgh, Ernan McMullin (University of Notre Dame) portrayed a rather gloomy scenario concerning the current relationship between history and philosophy of science (HPS), on the one hand, and mainstream philosophy, on the other hand, as testified by a significant drop in the presence of HPS papers at various meetings of the American Philosophical Association (APA).

This paper explores the scientific sources behind Kant’s early dynamic theory of matter in 1755, with a focus on two main Kant’s writings: Universal Natural History and Theory of the Heavens and On Fire. The year 1755 has often been portrayed by Kantian scholars as a turning point in the intellectual career of the young Kant, with his much debated conversion to Newton. Via a careful analysis of some salient themes in the two aforementioned works, and a reconstruction of the (...) scientific sources behind them, this paper shows Kant’s debt to an often overlooked scientific tradition, i.e. speculative Newtonian experimentalism. The paper argues that more than the Principia, it was the speculative experimentalism that goes from Newton’s Opticks to Herman Boerhaave’s Elementa chemiae via Stephen Hales’ Vegetable Staticks that played a central role in the elaboration of Kant’s early dynamic theory of matter in 1755.

This paper aims to clarify the program of Deleuze’s work on Hume’s philosophy. Also, I plan to make clear the operational meaning of Deleuze’s own hallmark regarding his approaches to philosophy. I start to follow Deleuze’s plot by engendering three functions of his interpretation of Hume’s Treatise that will be the area of three thematic chapters. The first tries to sort the polemical function of empiricism that is launched through Deleuze’s Hume; the second attempts to figure the domain of subjectivity (...) as the inventive function of the book; the third searches the creative function by describing the role of the institutional theory.

Russian occupation of Königsberg during the Seven Years’ War had a great impact on the residents of East Prussia capital. That time significantly changed the cultural city life, i.e. there was a release from narrow-mindedness and prejudices of the Protestant city that was influenced by Pietism; social mores were liberalized; in comparison with pre-war time the university started playing a more significant part, and the status of university professors rose. All these changes positively affected Kant’s life and his philosophical formation. (...) Because of the occupation Kant remained in contact with Prussian, Austrian, and Russian officers for many years, and made friends with a number of merchants. This influenced his position regarding the war, history understanding, and his assessment of Frederick the Great’s role and significance. (shrink)

In this study I provide a thematic comparison of Søren Kierkegaard’s Fear and Trembling and Immanuel Kant’s Groundwork of the Metaphysics of Morals to suggest that the representation of the ethical in Fear and Trembling is transparently Kantian. At times I draw on Kant’s Religion Within the Boundaries of Mere Reason, Conflict of the Faculties, and The Metaphysics of Morals to offer a comprehensive account of Kant’s ethical theory. Both philosophers hold profoundly important positions within the milieu of ethics, however (...) they have always shared a tenuous and at times negative relationship. In this study, I challenge such commentators by showing that when the figure of Abraham is taken typologically and excluded from the text, what emerges from Fear and Trembling is a Kantian based ethics. I argue that a comparative reading of Kant’s Groundwork and Kierkegaard’s Fear and Trembling reveals that Kierkegaard’s thought gravitates towards three central principles of Kant’s categorical imperative, as well sharing some similarities with Kant’s understanding of duty.

: Frege's philosophical writings, including the "logistic project," acquire a new insight by being confronted with Kant's criticism and Wittgenstein's logical and grammatical investigations. Between these two points a non-formalist history of logic is just taking shape, a history emphasizing the Greek and Kantian inheritance and its aftermath. It allows us to understand the radical change in rationality introduced by Gottlob Frege's syntax. This syntax put an end to Greek categorization and opened the way to the multiplicity of expressions producing (...) their own intelligibility. This article is based on more technical analyses of Frege which Claude Imbert has previously offered in other writings (see references). (shrink)

Over two hundred years after Immanuel Kant’s death, the first full, critical, and digital edition of his last manuscript is currently being completed by the Berlin-Brandenburgische Akademie der Wissenschaften. This edition stands in institutional continuity with Wilhelm Dilthey’s monumental Akademieausgabe of Kant’s writings that was grounded in Dilthey’s lastingly influential concept of the national, literary-philosophical archive. The new edition showcases Kant’s dynamic writing process as a matter of investigation in its own right. As I argue here, it brings into view (...) the constitutive role of the archive for both texts and interpretative practices. A historical perspective that links the legacy of the Akademieausgabe with the digital edition of the Opus postumum highlights the changing role of the archive in emphasising or de-emphasising the manuscript’s resistance to certain appropriations and stylisations of Kant as a thinker.

This paper discusses Immanuel Kant’s views on the role of experiments in natural science, focusing on their relationship with hypotheses, laws of nature, and the heuristic principles of scientific enquiry. Kant’s views are contrasted with the philosophy of experiment that was first sketched by Francis Bacon and later developed by Robert Boyle and Robert Hooke. Kant holds that experiments are always designed and carried out in the light of hypotheses. Hypotheses are derived from experience on the basis of a set (...) of heuristic principles. The function of experiments is testing hypotheses in order to either reject them as false, or else to transform them into empirical laws of nature. To this end, we must integrate the hypotheses that are confirmed by experiments with the a priori principles which are the foundations of natural science. Compared with Bacon, Boyle, and Hooke, Kant has elaborate views on the one hand, on how our theoretical and pre-theoretical assumptions bear on experimental practice, and on the other hand, on how the results of experimental activity can be integrated with theories to advance our knowledge of nature. However, Kant overstates the dependence of experiments on theories. (shrink)

This paper argues that the images evoked in the literature of the Spanish indignados, and other contemporary global justice movements, specifically those of disciplinary and social decadence, a space–time beyond the limits of the possible, obligations across generations, and, ultimately, of universal history as horizon and anticipation, reactivate the legal critique of absolute property that featured so prominently in nineteenth-century accounts of law, civil society, and revolutionary right, and then again in the context of twentieth-century decolonization and revolutionary movements. Insofar (...) as such images can be distinguished from concepts, following a certain reading of the critical tradition against the grain, they pave the way towards the formulation of a systemic critique or a ‘jurisprudence of indignation’, in the wake of the emergence, rise and current crisis of the global market.

This thesis develops a hermeneutic philosophy of science to provide insights into physics education. -/- Modernity cloaks the authentic character of modern physics whenever discoveries entertain us or we judge theory by its use. Those who justify physics education through an appeal to its utility, or who reject truth as an aspect of physics, relativists and constructivists, misunderstand the nature of physics. Demonstrations, not experiments, reveal the essence of physics as two characteristic engagements with truth. First, truth in its guise (...) as correspondence enables a human being to prepare for the distinctive event of physics. -/- Second, the event of physics occurs in human perception when someone forces a hidden reality to disclose an aspect of itself. Thus, the ground of physics is our human involvement with reality achieved by way of truth. -/- To support this account of physics, the thesis reports phenomenological investigations into Isaac Newton’s involvement with optics and a secondary school physics laboratory. These involve interpretations of Heidegger’s theory of beings, schema and signification. The project draws upon, and contributes to, the hermeneutic phenomenology of modern physics, a tradition in continental philosophy that begins with Immanuel Kant, and advances particularly from Martin Heidegger to Patrick Heelan. -/- The thesis advocates an ontological pedagogy for modern physics which has as its purpose each individual student’s engagement with reality and truth. Students may achieve this through demonstrations of phenomena that will enable them to dwell with physics, an experience that contrasts with their embroilment in modernity, and which perpetuates nature’s own science.

Resumen En este artículo de investigación trataré de repensar, dentro de la intuición marcada por Heidegger en su interpretación de Kant, el papel que juega la noción de imaginación, en su vinculación inexorable, por un lado, con la apercepción trascendental, y con el tiempo, por otro, a fin de alcanzar, al menos, un esbozo temático de tal imaginación en términos de auto-afección radical del sí-mismo. Y todo ello para mostrar la posibilidad de una lectura interpretativa que haga valer la importancia, (...) justamente, de un sí mismo y/o mismidad.In this paper, I will try to rethink Heidegger’s interpretation of the role of transcendental imagination within his understanding of Kant’s Critique of Pure Reason. My paper focuses on the connection between transcendental apperception on the one hand and the time on the other. In this sense, I will try to develop a thematic outline of such imagination in terms of radical self-affection of Selfhood. And this in order to show the possibility of an interpretative reading that asserts the importance, precisely, of a self and/or selfhood. (shrink)

On the assumption that theistic religious commitment takes place in the face of evidential ambiguity, the question arises under what conditions it is permissible to make a doxastic venture beyond one’s evidence in favour of a religious proposition. In this paper I explore the implications for orthodox theistic commitment of adopting, in answer to that question, a modest, moral coherentist, fideism. This extended Jamesian fideism crucially requires positive ethical evaluation of both the motivation and content of religious doxastic ventures. I (...) suggest that, even though the existence of horrendous evil does not resolve evidential ambiguity in favour of atheism, there are reasonable value commitments that would preclude those who hold them from satisfying extended Jamesian fideist conditions for committing themselves to classical theism. I then begin a discussion of a possible revisionary theistic alternative (in the Christian tradition) which – one might hope – may meet those conditions. An earlier, shorter, version of this paper was delivered as a keynote address at the APA Pacific 2007 Mini-Conference on Models of God. (shrink)

The shortest form of the Basic Argument against free will and moral responsibility runs as follows: [1] When you act, you do what you do—in the situation in which you find yourself—because of the way you are. [2] If you do what you do because of the way you are, then in order to be fully and ultimately responsible for what you do you must be fully and ultimately responsible for the way you are. But [3] You cannot be fully (...) and ultimately responsible for the way you are. So [4] You cannot be fully and ultimately responsible for what you do. This paper restates the Basic Argument and varies it in several different ways. (shrink)

In A Theory of Justice (1971), John Rawls introduces the concept of “reflective equilibrium.” Although there are innumerable references to and discussions of this concept in the literature, there is, to the present author's knowledge, no discussion of the most important question: Why reflective equilibrium? In particular, the question arises: Is the method of reflective equilibrium applicable to the choice of this method itself? Rawls's drawing of parallels between Kant's moral theory and his own suggests that his concept of “reflective (...) equilibrium” is on a par with Kant's concept of “transcendental deduction.” Treating these two approaches to justification as paradigmatic, I consider their respective merits in meeting the reflexive challenge, i.e., in offering a justification for choice of mode of justification. My enquiry into this topic comprises three parts. In the first part (Eng 2014a), I raised the issue of the reflexivity of justification and questioned whether the reflexive challenge can be met within the framework of A Theory of Justice. In this second part, I shall outline a Kantian approach that represents a paradigmatic alternative to Rawls. (shrink)

Once God is no longer recognized as the ground and the enforcer of morality, the character and force of morality undergoes a significant change, a point made by G.E.M. Anscombe in her observation that without God the significance of morality is changed, as the word criminal would be changed if there were no criminal law and criminal courts. There is no longer in principle a God's-eye perspective from which one can envisage setting moral pluralism aside. In addition, it becomes impossible (...) to show that morality should always trump concerns of prudence, concerns for one's own non-moral interests and the interests of those to whom one is close. Immanuel Kant's attempt to maintain the unity of morality and the force of moral obligation by invoking the idea of God and the postulates of pure practical reason are explored and assessed. Hegel's reconstruction of the status of moral obligation is also examined, given his attempt to eschew Kant's thing-in-itself, as well as Kant's at least possible transcendent God. Severed from any metaphysical anchor, morality gains a contingent content from socio-historical context and its enforcement from the state. Hegel's disengagement from a transcendent God marks a watershed in the place of God in philosophical reflections regarding the status of moral obligations on the European continent. Anscombe is vindicated. Absent the presence of God, there is an important change in the force of moral obligation. (shrink)

This issue of The Journal of Medicine and Philosophy assesses the deep and abiding tensions that exist among the competing epistemic perspectives that bear on medicine and morality. Concepts of health and disease, as well as the theoretical framing of medical ethics and health care policy, intersect with an overlapping set of culturally situated communities, striving to understand and manipulate the world in ways that each finds explanatory, appropriate, or otherwise befitting. The articles explore the complexities of framing public health (...) care policy to guide bioethical decision making in the face of the plurality of ethical viewpoints and moral rationalities—including health enhancing supplements, continuous sedation until death, medical futility, the protection of vulnerable populations, and competing professional obligations.

In this paper, I outline Kant’s attempt to account for the category of relations, which is concomitant with his effort to prove that atomism cannot describe human experience. Kant’s journey from the First Critique to his last work the Opus Postumum is a struggle against atomistic versions of the world. In the last instance, it is a transit from I think to I act; and it is also recognition that to act can only be performed in a relational manner in (...) community with others. In order to substantiate his explanation of real forces in the world, Kant rethinks and extends his understanding of the subject from the subject as the unity of apperception to the self-positing subject living in the world with others. In order to defend ‘the being in the world’ who ‘has rights,’ I argue that we need to return to Kant’s general account of rights for all humans in the world. (shrink)

ABSTRACT This study bears upon the ‘Heidegger case,’ that is, the relation of Heidegger’s philosophizing to his political involvements as Rector of the University of Freiburg 1933-4, and his subsequent silences on the subject of the Holocaust. I use the phrase ‘bears upon’ for Heidegger’s political involvement will serve as the ‘horizon’ for the study, my concern being the genesis of Heidegger’s position. Grounded in a musical ‘intuition’ and attunement, I take up the Nietzschean cipher for understanding proposed by Heidegger (...) himself for the self-understanding of the German people: the Apollonian-Dionysian duality, which I apply to the ‘being’ of Heidegger’s own philosophizing. Through this approach I hope to make an original contribution to Heidegger scholarship by showing that Heidegger’s fundamental ontology is overdetermined, evolving out of both the phenomenological demand for a rigorous method in establishing fundamental structures of existence and - at the same time – out of an Apollonian attempt to ‘tame’ Dionysian existence, including Heidegger’s own. Inextricably interlinked will be the argument that Heidegger’s Auseinandersetzung, his ‘confrontation,’ with Nietzsche precedes the overt engagement of his ‘Nietzsche’ lectures of the 1930s, and, further, that this more pervasive concern with Nietzsche figures in the Apollonian-Dionysian strife within Heidegger’s thinking and within his ‘being.’ Heidegger’s silences in the face of the Dionysian - as well as the Auseinandersetzung with Nietzsche - will be seen to precede his ‘silence’ in the face of the actuality and history of the Third Reich. What I am proposing one might characterize as Heidegger’s Auseinandersetzung - through Nietzsche - with v Heidegger, in a disclosure of the ontic roots of Heidegger’s ontology, an exercise in his own hermeneutics of facticity. I will pursue the trace of the Apollonian-Dionysian duality: in the Western philosophical tradition which Heidegger confronts, using Husserl and Nietzsche as exemplars; in Heidegger interpretation; in the relation between his texts and his letters; and in the suppressions and intensifications within Being and Time. And I will propose that the fugue and the mutually generative duality of suppression and intensification within Heidegger’s academic thinking were conditions of the possibility of Heidegger’s ‘way’ towards political involvement.

This thesis presents an interpretation of Immanuel Kant’s theoretical philosophy in which the notion of ‘force’ is of central importance. My analysis encompasses the full span of Kant’s theoretical and natural-scientific writings, from the first publication to the drafts of an unfinished final work. With a close focus on Kant’s texts, I explicate their explicit references to force, providing a narrative of the philosophical role and significance of force in the various periods of the Kantian oeuvre. This represents an intervention (...) into Kant scholarship that seeks to correct the marginal role accorded to ‘force’. The central problem that emerges through the thesis’ attention to force is: how to interpret the simultaneous separation and connection of physical and psychological forces in Kant’s mature, critical philosophy? Physical and psychological forces are strictly separated, and yet a common, ontological conception of force underpins these two domains. I show that this issue has its basis in a tradition of philosophical ‘dynamics’ stemming from Leibniz, which is examined in part one. The three parts of the thesis proceed chronologically through the Kantian oeuvre. Part one reconstructs the historical context of Leibnizian and Newtonian conceptions of force, and presents a narrative of the employment of force in Kant’s pre-critical writings, in their relation to the broad problematic of Leibniz’s dynamics. Part two explores the account of physical and psychological forces, and the common, ontological notion of force, in the major critical-period discussions. Part three presents the late works, namely the third Critique and the Opus postumum, as a ‘philosophy of force’, in which force, with all its necessary ambiguities, plays central roles in Kant’s late systematising endeavours. I conclude that the perspective of this thesis makes possible a new understanding of the nature and unity of Kant’s philosophical project. (shrink)
