This article aims to justify the positive role in the empirical investigation of nature that Kant attributes to the idea of God in the Critique of Pure Reason. In particular, I propose to read the Transcendental Ideal section and the Appendix to the Transcendental Dialectic together to see whether they can reciprocally illuminate each other. I argue that it is only by looking at the transcendental deduction of the ideas of reason and the resulting analogical conception (...) of God that a fully legitimate positive use of the idea of God can be vindicated.

Immanuel Kant: The Very Idea of a Critique of Pure Reason is a study of the background, development, exposition, and justification of Kant's Critique of Pure Reason. Instead of examining Kant's arguments for the transcendental ideality of space and time, his deduction of the pure concepts of the understanding, or his account of the dialectic of human reason, J. Colin McQuillan focuses on Kant's conception of critique. By surveying the different ways the concept of (...) critique was used during the eighteenth century, the relationship between Kant's critique and his pre-critical experiments with different approaches to metaphysics, the varying definitions of a critique of pure reason Kant offers in the prefaces and introductions to the first Critique, and the way Kant responds to objections, McQuillan is able to highlight an aspect of Kant's critical philosophy that is too often overlooked—the reason that philosophy is critical.

The Critique of Pure Reason—Kant’s First Critique—is one of the most studied texts in intellectual history, but as Alfredo Ferrarin points out in this radically original book, most of that study has focused only on very select parts. Likewise, Kant’s oeuvre as a whole has been compartmentalized, the three Critiques held in rigid isolation from one another. Working against the standard reading of Kant that such compartmentalization has produced, The Powers of Pure Reason explores forgotten parts (...) of the First Critique in order to find an exciting, new, and ultimately central set of concerns by which to read all of Kant’s works. Ferrarin blows the dust off of two egregiously overlooked sections of the First Critique—the Transcendental Dialectic and the Doctrine of Method. There he discovers what he argues is the Critique’s greatest achievement: a conception of the unity of reason and an exploration of the powers it has to reach beyond itself and legislate over the world. With this in mind, Ferrarin dismantles the common vision of Kant as a philosopher writing separately on epistemology, ethics, and aesthetics and natural teleology, showing that the three Critiques are united by this underlying theme: the autonomy and teleology of reason, its power and ends. The result is a refreshing new view of Kant, and of reason itself. (shrink)

In the preface to the second edition of the Critique of Pure Reason Kant explicitly states that his motivation for writing this work is to make room for faith or the practical employment of reason . How does Kant accomplish this? The topics of God and the immortality of the soul do not arise until the conclusion of the antinomies. How does Kant get from the desire to make room for faith to its fulfilment in the latter (...) parts of the first Critique? A common response to this question is a discussion of the constitutive and regulative employment of the ideas of reason. It is this distinction that sustains Kant's attempt at reconciling empirical knowledge and moral discourse. The constitutive and regulative analysis, however, has its roots deep within the initial stages of the Critique of Pure Reason. It is, in fact, the mathematical/dynamical distinction, which Kant introduces early in the analytic, that makes possible the constitutive/regulative distinction. Not only has the mathematical/ dynamical distinction itself been disregarded, but the relation between the mathematical/dynamical and the constitutive/ regulative has been almost universally ignored by commentators. If a commentator does mention the mathematical/dynamical distinction, it is usually in a dismissive tone. Walsh, for example, calls the distinction ‘hard to interpret’ and ignores it for the rest of his commentary. (shrink)

In this paper, we reconstruct Kant’s notion of the practically conditioned, introduced in the Dialectic of Pure Practical Reason, by drawing on Kant’s general account of the faculty of reason presented in the Transcendental Dialectic of the Critique of Pure Reason. We argue that practical reason’s activity of seeking the practically unconditioned for a given condition generates two different conceptions of the practically unconditioned and identify these as virtue and (the ideal of) happiness. We (...) then account for how and why reason proceeds to combine these two distinct ideas into the composite idea of the highest good. Last, we draw on our discussion to determine more precisely what Kant intends by the ‘supremacy’ of virtue within reason’s idea of the highest good. (shrink)

Hermann Cohen, as it is well known, criticised the Kantian notion of the thing-in-itself. And before him the Kantian thing-in-itself was criticised by Fichte and other German idealists. Probably for this reason, Hermann Cohen is sometimes regarded as a person who said things similar to Fichte. This gives a completely wrong perspective, making it impossible to understand the philosopher's ideas. The basis for his critique of the Kantian thing-in-itself is quite different from the motives, determining the criticism of (...) Kant in the classical German Idealism. Such interpretation does not allow to see close connection of Cohen's theoretical philosophy with revolution in physics which took place at the turn of the nineteenth and twentieth centuries. The article explains how Cohen's demand that pure thinking must form its own content is connected with transformations taking place in physics and mathematics, and the peculiarity of Cohen's understanding of idealism is demonstrated: for him, correct idealism must realize that autonomous, free thinking should work seriously with sense data. The closeness of Cohen's ideas to the postpositivist thesis of the theory-ladenness of observation is explained. For Cohen, serious work with sense data is opposite to uncritical acceptance of them as given. The origin of scientific thinking is thinking itself. It responds to the challenge of sensory material by creating its own constructs. Mathematized natural science becomes for Cohen both an example and a confirmation of this thesis. For him, what is real is what is described in the language of mathematical analysis, i.e. continuous processes, in spite of the fact that any data are discrete. It is shown that the source of Cohen's assertions on this issue is in Kant's Critique of Pure Reason, namely in the doctrine of the Principles of pure natural science and, more specifically, in the Anticipations of Perception. Cohen's conviction of the constructive character of the theories of mathematized natural science is confirmed in the article by references to the authority of A. Einstein. (shrink)

The aim of this paper is to propose a novel reading of the critical legitimacy of the regulative use of reason in the Transcendental Dialectic of Kant's Critique of Pure Reason. After introducing some key terminology of the Dialectic, I analyse the shortcomings of two influential accounts of the regulative use of reason and identify their common problem in their commitment to the descriptivity of the ideas of reason. I then offer my rule‐based account (...) of the regulative use of reason by clarifying how Kant transforms reason's metaphysical inclinations into prescriptive rules of bottom‐up empirical research. Finally, I explain why such interpretation of reason is metaphysically innocent and thereby a promising approach to understand its role in Kant's scientific project. (shrink)

A logic of grounding where what is grounded can be a collection of truths is a “many-many” logic of ground. The idea that grounding might be irreducibly many-many has recently been suggested by Dasgupta. In this paper I present a range of novel philosophical and logical reasons for being interested in many-many logics of ground. I then show how Fine’s State-Space semantics for the Pure Logic of Ground can be extended to the many-many case, giving rise to the (...) class='Hi'>Pure Logic of Many-Many Ground. In the second, more technical, part of the paper, I do two things. First, I present an alternative formalization of plg; this allows us to simplify Fine’s completeness proof for plg. Second, I formalize plmmg using an infinitary sequent calculus and prove that this formalization is sound and complete. (shrink)

This dissertation is a critical study of rationalism in ethics: the view that acting morally is a requirement of rationality, and that all agents consequently have reason to be moral. The study attempts first to reconstruct the essential elements of the rationalist approach in ethics, and then to identify the most critical obstacles in the way of that approach. By way of reconstruction, it is argued that the rationalist in ethics needs to construe rationality as a set of ideal (...) principles or norms, and to affirm a connection between one's having a practical reason and the capacity of rationality to lead one to be motivated to act on the reason. This latter claim amounts to a version of internalism, and some time is devoted to the task--hitherto neglected by philosophers--of clarifying and defending the connection which it postulates between practical reasons and the motivation to act on them. Given internalism, the burden on the rationalist is to show that rational reflection can by itself lead to the motivation to act on moral reasons. Opponents of rationalism have characteristically challenged the very possibility of such purely rational motivations, and the dissertation considers next the arguments that have been offered for this broadly Humean position. The conclusion is reached that there are no plausible a priori arguments against the very possibility of a rationalist explanation of motivation. This does not however represent a vindication of the rationalist approach: there is room for a pragmatic argument against purely rational explanations of motivation, and the dissertation concludes by offering such an argument, focussing in particular on the case of prudence and prudential reasons.

Kant’s late essay ‘The End of All Things’ (1794) establishes a distinctly modern field of inquiry that has fittingly been called ‘philosophical eschatology’ by asking, ‘why do human beings expect an end of the world at all?’ (AA 8:330) Interpretation of the essay’s purpose and argument have usually taken one of two routes: Kant is either understood as writing an esoteric political critique under the guise of the philosophy of religion, or as being focused largely on problems related to the (...) immortality of the soul as a postulate of pure practical reason. In contrast, I argue that the essay presents the end of all things as a cosmological idea of reason. In this essay I trace Kant’s idea of an end as its preconditions are established through the three Critiques, and finally made explicit in his late work. (shrink)

What makes scientific knowledge possible? The philosopher Immanuel Kant in his magnum opus, the Critique of Pure Reason, had a fascinating and puzzling answer to this question. Scientific knowledge, for Kant, is made possible by the faculty of reason and its demand for systematic unity. In other words, cognition about empirical objects can aspire to be scientific only if it is rationally embedded within or transformed into a system. But how can such system form once we take (...) into account the perspectival nature of knowledge, i.e., its being situated in individual human cognitive faculties? My PhD thesis has a two-pronged objective: to reconstruct the complexity of the notion of systematicity in Kant’s Critique of Pure Reason; and to defend its plausibility in contemporary debates on the unity or plurality of scientific knowledge. As far as is concerned, Kant’s position is far from being clearly understood in the literature. Despite a renewed interest in Kant’s notion of systematicity in recent decades, existing contributions fail to offer a satisfactory account of it. The aim of my thesis is to provide a unified reading of reason’s systematicity as an essential feature of Kant’s analysis of the sources of cognition. In particular, I defend a novel account of theoretical reason the aims to support the following claims: systematicity is grounded in a legitimate use of reason’s ideas as prescriptive rules for empirical investigation; it is necessary to make empirical cognition possible and generate scientific hypotheses; and it gives us fundamental insights into Kant’s ‘empirical realism’ and his understanding of the role of metaphysics in science. With regard to, I show that Kant’s account of theoretical reason has much more to offer than generally acknowledged. In particular, I present it as providing a reconciling solution to the conflict between unity and pluralism in contemporary philosophy of science. Drawing inspiration from Kant’s ‘perspectivism,’ I argue that unity and pluralism are to be thought as mutually inclusive principles of scientific knowledge. (shrink)

In his response to the question about the conditions of the possibility of dependable cognition Kant first points to the faculties of the cognitive powers and subsequently lists the criteria and normative foundations of knowledge—a system of forms, concepts and principles. Kant primarily seeks the possibilities of experience-independent cognition, the logical criteria governing the possibility of cognition as such. The paper outlines the creation of the systemic union of the primal concepts and principles of pure reason, which is (...) necessary for the creation of knowledge. In other words, it follows the constitution phases of the cognition system: apperception, experience, self-consciousness and the principles of reason. The principles of reason ultimately give systemic unity to humancognitive powers—and, in effect, the human world of experience and cognition. It is this systemic unity which makes cognition science—or, in other words, pure reason—as it constitutes a specific system and is able to create science understood as the systemic unity of specific fields.

“Ethical life” is Hegel’s term for the actuality of what Kant calls an “ethical community.” As members of the same ethical community, human beings are related to one another as persons in and only in acting from nothing but respect for the same practical law. Kant and Hegel both take ethical life to be a necessary, nay, the highest, end of pure reason. I argue that this is correct. And I identify the idea of ethical life with the (...) idea of a peculiar form of love. Kant and Hegel disagree—in a curiously reciprocal fashion—about the reach of ethical life and about our capacity to know it to reside within our power: while Kant identifies ethical life with the actuality of the ethical community of all possible human beings, Hegel holds that it is necessarily limited to some particular body politic; and while Hegel thinks that to be a human being is to self-knowingly co-constitute an ethical community, Kant believes that it is to be unable to know oneself to even be apt for this. With Hegel and against Kant, I argue that the only way to have the idea of ethical life is to live it. But with Kant and against a naïve form of Hegelianism, I argue that to be conscious of oneself as a human being, a practically rational animal, is to be conscious of oneself as morally evil, i.e. as actively prone to deeming one’s own particularity the supreme law. I show that this entails Hegelian particularism. And I end by noting that this saddles the Hegelian with the task of demonstrating that ethical particularization belongs to the very idea of pure reason itself, objectively conceived. (shrink)

Reason is precariously positioned in the Critique of Pure Reason. The Transcendental Analytic leaves no entry for reason in the cognitive process, and the Transcendental Dialectic restricts reason to noncognitive roles. Yet, in the Appendix to the Transcendental Dialectic, Kant contends that the ideas of reason can be used in empirical investigation and eventually knowledge acquisition. Given what Kant has said, how is this possible? Kant attempts to answer this in A663–A666/B691–B694 in the (...) Appendix, where he argues that principles of reason “have objective but indeterminate validity.” In Part I of this paper, I explain the full motivation behind this section. In Part II, I provide an exegesis of it. In particular, to reach his conclusion that principles of reason have objective but indeterminate validity, I interpret Kant as making three arguments from analogy. Finally, in Part III, I show that the first and third arguments fail—and what this means for Kant’s project. (shrink)

For Kant the definitive end of art is the expression of aesthetic ideas that are sensible counterparts of rational ideas. But there is another type of aesthetic idea: ‘Beauty can in general be called the _expression_ of aesthetic ideas: only in beautiful nature the mere reflection on a given intuition, without a concept of what the object ought to be, is sufficient for arousing and communicating the idea of which that object is considered as the _expression_.’ What (...) are these aesthetic ideas? I argue that Kant is drawing on the idealist conception of art, associated with Vasari, Bellori and Winckelmann, as presenting idealized spatial forms characteristic of natural kinds. He incorporates this conception into his analysis of the beauty of nature and adds that we have non-conceptual access to it. These idealized forms he names aesthetic normal ideas of natural species. §51 of Kant’s Critique of the Aesthetic Power of Judgment opens with an unexpected claim, described by readers as ‘puzzling’, ‘perplexing’ and even as a ‘notorious mystery’.1 1 Beauty can in general be called the _expression_ of aesthetic ideas: only in beautiful art this idea must be occasioned by a concept of the object, but in beautiful nature the mere reflection on a given intuition, without a concept of what the object ought to be, is sufficient for arousing and communicating the idea of which that object is considered as the _expression_. 2 2 I will argue that, in this passage, Kant states that there are two types of aesthetic ideas—namely, aesthetic ideas expressed in beautiful art and aesthetic ideas expressed by beautiful nature. This distinction is surprising for, before this juncture, there is no explicit claim that there are different types of aesthetic ideas. In fact, although Kant offers several seemingly general characterizations of aesthetic ideas, in none of them does he indicate that there is a subdivision of the genus. Noteworthy, too, is the claim that the distinct pleasure we take in beautiful nature is independent of concepts; for strikingly, it can be considered as the expression of what the passage above expressly calls ideas. In his analysis of fine art, Kant draws the distinction between natural and artistic beauty—a distinction that is succinctly repeated in the passage above.3 3 But when he goes on to explicate the notion of an aesthetic idea, he refers only to aesthetic ideas expressed in art. This fact is taken to support the assumption that aesthetic ideas are connected solely to art. This is the heart of the mystery of the passage, for in it, Kant explicitly talks about aesthetic ideas expressed by beautiful nature. This raises a crucial question: Does the explication of aesthetic ideas in the sections on art apply to aesthetic ideas of beautiful nature?I maintain that the answer is negative. Although, in the passage above, Kant uses the same term in relation to both kinds of beauty, he has a clear distinction in mind: Beauty in art is an aesthetically or sensuously unified expression of the conceptual richness of an idea of reason; beauty in nature is an expression of a purely aesthetically or sensuously unified richness. Obviously, this distinction is connected to other significant differences between the two kinds of beauty. But it is important to point out at the outset that the two types of aesthetic ideas have in common only the quality of being a sensuously unified richness. It is in this sense that they are both species of a single genus. But what more precisely does Kant mean by aesthetic ideas expressed by beautiful nature, and what unified richness do they express and how precisely do they express it? It is to the historical genealogy of this notion of aesthetic ideas of beautiful nature and its implications for Kant’s theory of beauty that this paper is devoted. This historical genealogy will reveal a sense of the notion of aesthetic ideas that we easily overlook but would have been familiar to Kant and his contemporaries. (shrink)

It is not just rationalist metaphysics, but also Kant’s transcendental philosophy that is teeming with a priori concepts. According to Kant, some of these a priori concepts are “ideas,” and similar to the categories, some of these ideas in turn belong to the nature of human reason, while others can be derived from them. It is therefore part of Kant’s claim in the “Transcendental Dialectic” to be able to explain not only the leading ideas of rational (...) psychology, cosmology, and theology as natural concepts of reason, but the origin of the entire a priori vocabulary of the metaphysica specialis as well. This article outlines how Kant’s derivations of these concepts work. After explaining Kant’s classification of a priori concepts and the derivation of the transcendental ideas, his derivations are explored in more detail using the example of the concepts of the pure doctrine of the soul. This contributes to a better understanding of Kant’s theory of philosophical concepts while also shedding light on the rather rarely treated topic of the “Transcendental Dialectic.”. (shrink)

Kant describes the concept of freedom as "the keystone of the whole structure of a system of pure reason, even of speculative reason." Kant's theory of freedom thus plays a foundational and unifying role in all aspects of his philosophy and is thus of significant interest to historians of Kant's philosophy. Kant's theory of freedom has also played a significant role in contemporary debates in metaphysics, normative ethics, and metaethics. This volume brings historians of Kant's philosophy into (...) conversation with contemporary metaphysicians and ethicists with the aim of representing the current state of scholarship on Kant's and Kantian accounts of freedom while at the same time opening new avenues of exploration. The Idea of Freedom includes papers by leading scholars on a range of historical and contemporary topics centrally related to the Kantian theory of freedom, including transcendental idealism, determinism, Kant's normative ethical theory, Kant's conception of cognition, Kant's theory of beauty, Kant's conception of logic, and many others.

In his Critique of Pure Reason, Kant famously includes immortality as one of the three “ideas” that give rise to “unavoidable problems of reason” (KrV, B7)1 and thereby constitute the basic subject-matter of metaphysics. Interpreters have paid a great deal of attention to the other two ideas, God and freedom; yet very few studies of Kantian immortality have ever been undertaken. This should come as no surprise, once we realize that Kant himself used the word (...) “immortality” and its cognates only 40 times in all three of his great Critiques. (By comparison, forms of the words “God” and “free(dom)” appear 119 and 509 times, respectively, in the three Critiques.) Kant’s theory of immortality – if he can be said to have one – is therefore exceedingly difficult to understand. For example, he says at one point (KrV, B395n): “Metaphysics has only three ideas as the proper purpose of its investigation: God, freedom, and immortality – and in such a way that the second concept, when combined with the first, is to lead to the third as a necessary conclusion.” How are we to understand this claim ? Does Kant really mean that combining the concept of freedom with the concept of God somehow gives rise to immortality as a necessary inference? In any case, why does Kant say so little about immortality, even though he portrays it as one of three ideas that constitute the “final aim” of all metaphysical speculation ? These and other puzzles raised by Kant’s occasional comments on immortality will be the focus of this paper. (shrink)

I argue that Kant has developed a broad systematic account of the architectonic functionality of pure reason that can be used and advanced in contemporary contexts. Reason, in the narrow sense, is responsible for the picture of a well-ordered universe of science consisting of architectonic ideas of science, sciences and parts of sciences. In the first section (I), I show what Kant means by the architectonic ideas by explaining and interrelating the concepts of (a) the (...) faculty of reason, (b) ideas (as principles), (c) method, and (d) sciences of reason. Thereafter (II), I think through his holistic understanding of science and scientific progress and suggest differentiating between four levels of use of architectonic ideas, drawing on the metaphor of a well-structured universe as imagined by Kant in his work on the Universal Natural History and Theory of the Heavens. I also claim that each possible idea of reason can be (apart from its primary function) additionally regarded as a fourth-level architectonic concept when explicitly conceived as an object of (e. g. philosophical) studies, i. e. from a mere methodological perspective. In the final section (III), I unveil the potential of Kant’s theory by pointing out how this architectonic methodological function of pure reason is tacitly used in Karl-Otto Apel’s contemporary philosophical research programme.

In this contribution, I respond to articles published in a Topical Issue of Open Philosophy on Kant’s Transcendental Dialectic by Mario Caimi, Gabriele Gava, and Michael Lewin, who criticize some of the views I put forward in my book Kant on the Sources of Metaphysics: The Dialectic of Pure Reason. In particular, I discuss the “real use” of reason, the “regulative use” of principles and ideas of reason, and Kant’s conception of reason.

In The Architectonic of Reason Lea Ypi argues that Kant ultimately fails in his attempt at grounding the systematic unity of reason because of the lack of the practical domain of freedom in the first Critique. I aim to advance a more nuanced reading of Kant’s alleged failure by (1) distinguishing between the schematism of the ideas in the Appendix to the Transcendental Dialectic and the schematism of pure reason in the Architectonic. (2) I suggest (...) that, while the practical domain of freedom is not established in the first Critique, the Canon and the Architectonic do account for its condition: the practical employment of reason and its unity with the theoretical. I point out that while (3) the schematism of the ideas accounts for the sole systematic arrangement of the understanding’s cognitions and the regulative role of the ideas and the ideal, in the Architectonic, (4) the schematism of pure reason instead bears more generally on systematicity as reason’s way of proceeding in framing its own unitary whole and the unity between its two lawful employments.

In this paper, I shall discuss the assumption that Kant’s method in the Critique of Pure Reason is a transcendental analysis of experience. In order to do this, I will consider the conception of transcendental analysis that Marburg Neo-Kantianism powerfully introduced into Kant interpretation. I shall first develop a general model of transcendental analysis in the Marburg sense. I shall then ask whether this is a suitable model for the interpretation of the first Critique. Kant’s distinction between the (...) analytic and synthetic method in the Prolegomena seems to contradict this, given that it is a distinction between two different mathematical methods of demonstration. However, I shall argue that any such reading is incompatible with the Critique, and that transcendental analysis is indeed a legitimate interpretative model for understanding Kant. I shall finally turn to Strawson’s conception of descriptive metaphysics, which has strong affinities to Kant and the Marburg school. Most importantly, Strawson helps us to understand three significant aims at which transcendental analysis is directed. Finally, comparing transcendental analysis to dominant conceptions of analysis in philosophy, I shall argue that it constitutes a variety of philosophical analysis sui generis. (shrink)

As Kant claimed in the Groundwork, and as the idea has been developed by Korsgaard 1997, Bratman 1987, and Broome 2002. This formulation is agnostic on whether reasons for ends derive from our desiring those ends, or from the relation of those ends to things of independent value. However, desire-based theorists may deny, against Hubin 1999, that their theory is a combination of a principle of instrumental transmission and the principle that reasons for ends are provided by desires. Instead, they (...) may say, there is just one principle, a principle of, if you will, instrumental transmutation: if one desires the end, then one has reason to take the means. See the discussion of General Production, in section 8, for a doubt about this. (shrink)

In two often neglected passages of the Critique of Pure Reason, Kant submits that the Critique is a 'treatise' or a 'doctrine of method'. These passages are puzzling because the Critique is only cursorily concerned with identifying adequate procedures of argument for philosophy. In this book, Gabriele Gava argues that these passages point out that the Critique is the doctrine of method of metaphysics. Doctrines of method have the task of showing that a given science is indeed a (...) science because it possesses 'architectonic unity' – which happens when it realizes the 'idea' of a science. According to Gava's novel approach, the Critique establishes that metaphysics is capable of this unity, and his reading of the Critique from this perspective not only illuminates the central role of the Transcendental Doctrine of Method within it, but also clarifies the relationship between the different parts of the work.

Charvet’s arguments revolve around very recent discussions in Anglo-American analytical ethics and political philosophy. He considers and rejects, for example, arguments in favor of both Thomas Nagel’s version of ethical realism and the view that value is constituted by fulfillment of our strongest desires. Both suffer from the inadequate “shared assumption as to the fundamental independence of desire and value, and hence desire and reason”. Instead, we should see both as “interdependent”; value “comes into the world through the medium (...) of the interacting desire and the belief systems of the organism as these articulate and project onto the environment the organism’s needs”. He likewise rejects Nagel’s and Parfit’s views on prudential rationality and personal identity, arguing that no “attempt to establish [personal identity] purely in impersonal terms” can succeed, that “the self is a basic primitive concept that is presupposed in all experience”.

In the controversial Appendix to the Transcendental Dialectic, Kant claims to “complete the critical work of pure reason” [A670/b698] by providing a transcendental deduction of the ideas of pure reason. In order to analyse the role that this Appendix plays in the first Critique, this paper will read the Appendix alongside Kant’s comments in the B-Preface concerning the astronomy of Copernicus. Through an analysis of the nature of Kant and Copernicus’ respective use of presuppositions, and (...) by looking at their respective attempts to unify a science around a single systematic conception of the object of that science, this paper will offer a defence of the fundamental role that Kant’s transcendental deduction of the ideas of pure reason plays in the text.

The subject matter of the article is the concept of “the real use of reason” alluded to by Kant in Critique of Pure Reason A299/b355 and in A305/b362. After comparing it with the “real use of understanding” examined in De mundi sensibilis and in the Critique of Pure Reason, the real use of reason is presented as a legitimate and useful performance that should be distinguished from the deceiving illusion induced by an appearance generated (...) by reason itself. The real use of reason proves itself as an unavoidable condition for the regulative use of ideas as well as a condition for the production of a critical metaphysics. (shrink)

This essay argues for a unifying and clarifying analysis of Fichte’s diverse and unusual characterizations of the nature of reason and rational normativity. Fichte equates or closely associates reason with “I-hood,” “positing” (especially self-positing), “acting” (as opposed to being), “self-reverting activity,” and “subject-objectivity.” He also claims that reason, qua reason, harbors “an absolute tendency toward the absolute” – and even that, in the final analysis, “only reason is.” I argue that we can readily grasp the (...) meaning, interconnection, and putative justification of such claims, if we suppose that, for Fichte, reason is the self-initiated instatement of self-wrought ordering forms, the first and foremost of which is the idea of precisely this type of activity in a pure and uncompromised (independent, “self-sufficient”) form.

Over the last two decades there has been a growing interest in the transcendental dialectic of Critique of Pure Reason in Germany. Authors, however, often do not pay enough attention to the fact that Kant’s theory of reason (in the narrow sense) and the concept of ideas derived from it is not limited to this text. The purpose of this article is to compare and analyze the functionality of mind as a subjective ability developed by Kant (...) and Fichte with the Hegelian expansion of the mind to the idea of universal rationality. The relevance of such a comparison is connected with the need to demonstrate how the Hegelian paradigm of absolute rationality causes either the subsequent rejection of reason as a philosophical principle in the 19th and´20th centuries counter-discourse, or reduction of reason to the concept of pragmatic rationality. In the first part of this paper, the author intends to differentiate between at least 7 different types of ideas and their functions in Kant’s works. In the second part, he demonstrates how Fichte tries to systematize them beginning with reason, which at first creates an idea of itself. Special attention is paid to the way that Fichte categorizes them with the help of 5 spheres of action or 5 worldviews. The third and final part of the article discusses how Hegel goes beyond the frame of the transcendental philosophy of consciousness using different demands linked to the concepts of “reason” and “ideas”. Although these requirements are not found in Kant and Fichte, they entail a set of difficulties, which the author considers in conclusion. The author’s interpretation of the theory of ideas and their functions in Kant, Fichte and Hegel demonstrates the dynamic character of the theories of reason in classical German philosophy, as well as the relevance of the 7 types of ideas that retain their significance for philosophy of the 21st century. Keywords: Kant and German idealism, types of ideas, functions of reason, worldviews, the problem of different demands. В Германии на протяжении последних двух десятилетий возрос интерес к трансцендентальной диалектике «Критики чистого разума». Однако авторы часто не обращают внимания на то, что кантовская теория разума (в узком смысле), в которой разворачивается работа с идеями, не ограничивается этим текстом. Целью данной статьи является сравнительный анализ разработанной Кантом и Фихте функциональности разума как субъективной способности с гегелевским расширением разума до идеи всеобщей разумности. Актуальность такого сравнения связана с необходимостью продемонстрировать то, каким образом гегелевская парадигма абсолютной разумности вызывает либо последующий отказ от разума как философского принципа в контрдискурсе XIX–XX вв., либо редукцию разума к понятию прагматической рациональности. В первой части данной статьи вводится различение по меньшей мере семи различных видов идей и связанных с ними функций в философии Канта. Во второй части демонстрируется попытка Фихте их систематизировать исходя из утверждения том, что разум должен сначала создать идею о самом себе. Проанализировано также предложенное Фихте распределение идей на пять сфер действенности или типов мировоззрения. В третьей, итоговой части статьи рассмотрен выход гегелевской мысли за рамки трансцендентальной философии сознания. Автор статьи связывает этот процесс с выдвижением не осуществимых в контексте философии Канта и Фихте требований к понятиям «разум» и «идея» и анализирует ряд сложностей, вызванных этими требованиями. Таким образом, интерпретация учения об идеях и их функциях у Канта, Фихте и Гегеля демонстрирует динамический характер теорий разума в классической немецкой философии и актуальность семи видов идей, которые сохраняют свое значение для философии XXI в. Ключевые слова: Кант и немецкий идеализм, виды идей, функции разума, мировоззрение, проблема различных требований. (shrink)

Spinoza teaches that the nature of things expresses itself in two ways: in motion and in the world of bodies, on the one hand, and in the intellect with its world of ideas, on the other. Physical bodies are in perpetual motion – arising, changing, disappearing; since the human body also participates in these processes, they are perceived by senses. Spinoza calls the knowledge of sensual properties and duration of the existence of bodies “imagination”. The human mind processes images (...) of bodies with the help of a special kind of abstractions, the “beings of reason”, and then it forms, on the basis of “general concepts”, adequate ideas about the “inner essences” of things, their “order and connec­tion”, i.e. about the causes for the existence of things and their causal relations. Scientific definitions, formulae and models represent these causes and relations in a perfectly pure form – “under a species of eternity”. The article shows how Spinoza delineates the limits of human cognition: they are set by the nature of mind as the idea of the body (man con­sists of two modes of substance – the living body and its idea/mind in the infinite intel­lect). The wider the scope of the body’s activity, the more our mind knows about the world and about itself. The last section of the article describes the relationship of rea­son to virtue, logic to ethics, and characterises the way of life “according to the guidance of reason”. Social life appears to Spinoza as a battle of “passions”, the passive affects of solidarity and enmity. Society cannot live according to the guidance of reason, but our minds can find a form of government that minimises the damage caused by the “blind af­fects” of the rulers and the crowd: Spinoza considered democracy to be the “completely absolute state”.

It is a popular view thatpractical deliberation excludes foreknowledge of one's choice. Wolfgang Spohn and Isaac Levi have argued that not even a purely probabilistic self-predictionis available to thedeliberator, if one takes subjective probabilities to be conceptually linked to betting rates. It makes no sense to have a betting rate for an option, for one's willingness to bet on the option depends on the net gain from the bet, in combination with the option's antecedent utility, rather than on the offered (...) odds. And even apart from this consideration, assigning probabilities to the options among which one is choosing is futile since such probabilities could be of no possible use in choice. The paper subjects these arguments to critical examination and suggests that, appearances notwithstanding, practical deliberation need not crowd outself-prediction. (shrink)

This paper examines the metaphors of 'preformation' and 'epigenesis' in Kant's Critique of Pure Reason and his other references to and various uses of theories of biological generation. It asks what these metaphor are meant to do, philosophically, and whether the idea of epigenesis, in particular, can help explain the specificity of transcendental idealism in relation to empiricism, or whether it illuminates anything concerning the status or the function of the categories. Discussing the most important interpretations of the (...) epigenesis metaphor in the Critique of Pure Reason by Philip Sloan, Günter Zöller and John Zammito, this paper suggests an alternative interpretation of the generative metaphorics surrounding Kant’s presentation of the spontaneous production of the pure concepts by the understanding. Placing the single reference to epigenesis in Critique of Pure Reason in the context of the book’s larger set of metaphors of generation, birth and biological ancestry, this paper argues that the generative model for the production or origin of the categories is in fact that of parthenogenesis, and that this is the only generative model that could have secured the epistemic status and legitimacy of the categories in the Critique of Pure Reason for Kant. This argument also reveals the gendered imaginary subtending Kant’s transcendental idealism and allows us to consider the implications of the parthenogenic model for Kant’s transcendental idealism in this light.

In this article, I claim that the Antinomy of pure reason emerges as the result of synthetic activities that require succession. In this regard, I show that cosmological conflicts involve different kinds of representations: cosmological ideas, purely conceptual representations of the unconditioned and the product of non-temporal synthetic activities; and putative complete series of spatiotemporal conditions, which require temporal synthetic activities. As I show, purely conceptual representations cannot produce cosmological conflicts: The Antinomy requires the interaction of (...) class='Hi'>reason, understanding, and sensibility. I also discuss the maxim and principle of pure reason, how they lead to the unconditioned, and how the cosmological syllogism produces the Antinomy. (shrink)

According to recent scholarship, Kant’s "An Answer to the Question: What is Enlightenment?" and the introductory section to "The Conflict of the Faculties" are masterpieces of philosophical rhetoric. The philosophical significance of these texts lies in establishing the free public use of reason as a tool to discipline political power through pure practical reason, and the rhetorical mastery consists in presenting the free public use of reason as a means to satisfy the ruler’s pragmatic practical (...) class='Hi'>reason. Elaborating on this interpretation, I flesh out three further aspects of the writings in question. First, I examine the four types of arguments that Kant crafts in defence of the public use of reason and show how their pragmatic practical character is fully in keeping with the foundation of politics on pure practical ideas. Second, contrasting Kant’s notion of the public use of reason with the classical liberal conception of free speech, I argue that the distinctive character of Kant’s notion of the public use of reason consists in adding to the liberal demand for freedom from state censorship the requirement of the self-discipline of the participants in the public use of reason. Third, I contend that Kant’s notion of the public use of reason goes beyond a mere non-coercive discursive procedure and conclude that, to qualify as public in the distinctive Kantian sense, publicly presented positions must uphold theoretical and moral criteria informed by critical philosophy.

Expected-utility theory has been a popular and influential theory in philosophy, law, and the social sciences. While its original developers, von Neumann and Morgenstern, presented it as a purely predictive theory useful to the practitioners of economic science, many subsequent theorists, particularly those outside of economics, have come to endorse EU theory as providing us with a representation of reason. But precisely in what sense does EU theory portray reason? And does it do so successfully? There are two (...) strikingly different answers to these questions in the literature. On the one hand, there is the view of people such as David Gauthier that EU theory is an implementation of the idea that reason's only role is instrumental. On the other hand, there is the view suggested by Leonard Savage that the theory is a “formal” and noninstrumental characterization of our reasoning process. (shrink)
