Kant: Theoretical and Practical Reason

Kant infamously claimed that all human beings, without exception, are evil by nature. This collection of essays critically examines and elucidates what he must have meant by this indictment. It shows the role which evil plays in his overall philosophical project and analyses its relation to individual autonomy. Furthermore, it explores the relevance of Kant's views for understanding contemporary questions such as crimes against humanity and moral reconstruction. Leading scholars in the field engage a wide range of sources from which (...) a distinctly Kantian theory of evil emerges, both subtle and robust, and capable of shedding light on the complex dynamics of human immorality.

This paper presents a critique of a prevailing conception of the relation between moral reasoning and judgment on the one hand, and moral goodness on the other. I argue that moral reasoning is inescapably vulnerable to moral, as opposed to merely theoretical, failure. This, I argue, means that there is something deeply misleading in the way that Kant's moral theory, and some of its main rivals, have invited us to conceive of their subject matter.

Kant maintained that in order for an act to have moral worth it is necessary that it be done from the motive of duty. On the traditional view of Kant, the motive of duty is constituted solely by one’s belief or cognition that some act is one’s duty. Desire must be ruled out as forming partof the moral motive. On this view, if an agent’s act is to have moral worth, then it must be the ease that his belief that (...) he has a duty has, on its own, motivational force.I attempt to argue that this view is mistaken, that for Kant desire does have a place in moral motivation, and that for Kant it is not possible that we can have an obligation, sincerely assert that we have, and at the same time have no desire to perform that obligation.

In this paper, I analyze Kant’s theory of action and if human beings can act morally without being moved by sensible feelings. I will show that the answer of the Critique of Pure Reason, Groundwork and the Critical of Practical Reason is without any doubt “yes”, but Kant is ambiguous in the Metaphysics of Morals and also in the Anthropology. In the Metaphysics of Morals, Kant claims that there are some sensible conditions to the reception of the concept of duty: (...) moral feeling, conscience, love of one’s neighbor, and respect for one self . I examine moral feeling and love of human beings, trying to figure out whether or not they are necessary sensible pre- conditions to moral actions. (shrink)

This work seeks to develop a Kantian ethical theory in terms of a general ontology of values and norms together with a metaphysics of the person that makes sense of this ontology. It takes as its starting point Kant’s assertion that a good will is the only thing that has an unconditioned value and his accompanying view that the highest good consists in virtue and happiness in proportion to virtue. The soundness of Kant’s position on the value of the good (...) will is defended against criticisms directed against it by G. E. Moore and it is argued that there is an ambiguity in Moore’s notion of ‘intrinsic value’ that makes him unable to fully understand and appreciate the Kantian view. It is also argued that the special value of moral goodness has been unduly neglected in modern moral philosophy, even by those working in the Kantian tradition, and it is suggested that the possibility of a Kantian ethical theory centred on the notion of the highest good remains to be explored. In order to lay the ground for such a theory a Kantian approach to reasons for action and the metaphysics of the person is developed and defended, albeit in a way that, in contrast to Kant himself, emphasizes the social dimension inherent in being a person and acting on reasons. It is also argued that there exists what Henry Sidgwick has called a dualism of practical reason, which means that there are two systematic modes, the self-interested and the moral, of approaching action. These two modes correspond to the two components of the highest good as understood by Kant and it is argued that the highest good represents a reasonable way of unifying them. These two parts of the highest good are then considered, each in turn, and Kantian models for understanding them are elaborated and defended against main rivals. On the matter of happiness, it is argued that standard philosophical theories fail to properly account for the way in which a subject’s own opinions about what constitutes her happiness are important in determining where her happiness actually lies. On the matter of morality, Kantianism is contrasted with consequentialism, the other leading theory that understands morality in terms of an ideal of impartiality and it is argued that the Kantian ideal, which can be called ‘impartiality as universalizability’ is superior to the consequentialist one, which can be called ‘impartiality as impersonality’. A version of Kantian ethics that places its emphasis on the Formula of Universal Law is then elaborated and it is argued that it is reasonable to understand maxims, or at least those maxims eligible for the universalizability test, as having to do with the basic general principles according to which we live. This kind of interpretation creates a large room for the exercise of judgment on the part of the agent and it is suggested that the standards according to which such judgment is exercised are largely determined through our actual moral practices and discourses.

Commentators typically neglect the distinct nature and role of hope in Kant’s system, and simply lump it together with the sort of Belief that arises from the moral proof. Kant himself is not entirely innocent of the conflation. Here I argue, however, that from a conceptual as well as a textual point of view, hope should be regarded as a different kind of attitude. It is an attitude that we can rationally adopt toward some of the doctrines that are not (...) able to be proved from within the bounds of mere reason – either theoretical or practical. This does not mean that hope is unconstrained; there are rational limits, as we shall see. In fact one of my central claims here is that a crucial difference between knowledge, rational Belief, and rational hope is that they are governed by different modal constraints; section II discusses those constraints and the kind of modality involved. In section III, I return to Religion and offer what I take to be Kant’s account of the main objects of rational hope in that text – namely, “alleged outer experiences (miracles)”;a “supposed inner experience(effect of grace)”;and a future collective experience (the construction of a truly ethical society).

A central theme of Kant’s approach to moral philosophy is that moral obligations are categorical, by which he means that they provide supremely authoritative reasons for acting independently of an agent’s ends or interests. Kant argues that this is a reflection of our distinctive freedom or autonomy, as he calls it, as moral agents. A less, well- appreciated aspect of the Kantian picture of morality and respect for the dignity of each individual person is the idea of reciprocal accountability, that (...) moral agents are mutually responsible for their treatment of one another. Viewing Kant’s ethics from this second-person standpoint opens up a line of thought that promises to vindicate the Kantian idea that moral obligations are categorical imperatives. (shrink)

There are two ways in which philosophical controversialists can approach a classical opponent of their views. They can attempt to refute him, or they can try to show that, while generally assumed to be an opponent, the philosopher really was not, at least when he was thinking clearly. Of these two strategies, the latter, if it can be pulled off, is dialectically..

Is practical reason a cognitive faculty? Do practical judgments make claims about a subject matter that are appropriately assessed in terms of their agreement with that subject matter? According to Kantians like Christine Korsgaard, the answer is no. To think otherwise is to conflate the theoretical and the practical, the epistemic and the ethical. I am not convinced. In this paper, I motivate my skepticism through examination of the very figure who inspires Korsgaard’s rejection of cognitivism: Kant. For as I (...) read him, Kant does not construe the distinction between theoretical and practical reason in terms of a distinction between cognitive and non-cognitive faculties but in terms of two distinct applications of a single faculty of reason, which is through-and-through cognitive. Thus, practical, no less than theoretical, reason cognizes a subject matter, and so practical, no less than theoretical, reason is straightforwardly subject to familiar epistemic standards of truth, warrant, and knowledge. Of course, even if I am right about Kant, this does not show that Korsgaard is wrong about reason; and I will offer no direct argument against her position here. Nonetheless, I believe that reflection on Kant’s true view, with its careful treatment of and respect for both the practicality and rationality of reason, should perhaps lead us to rethink what it means to be a rationalist in ethics.

Many Kantian scholars have debated what normative guidance the formula of the law of nature provides. There are three ways of understanding the role of FLN in Kant’s ethics. The first line of interpretation claims that FLN and FLU are logically equivalent. The second line claims that there are only subjective differences, meaning that FLN is easier to apply than the abstract method of FUL. The third line of interpretation claims that there are objective diff er- ences between FLN and (...) FUL in the sense that each formula has an irreducible role in Kant’s ethics. In this article I will show that the first and second lines of interpretation cannot fully explain Kant’s account of FLN and I will propose a new interpretation which pertains to the third type. I will explore the schematism model to understand the role of FLN and argue that it is an intermediary principle that fills in a practical gap between the moral law and action. In the end, I will consider a possible objection against this understanding which claims that the schematism model is not applicable to practical judgment since nothing is given in experience.

Schopenhauer presents his moral philosophy as diametrically opposed to that of Kant: for him, pure practical reason is an illusion and morality can arise only from the feeling of compassion, while for Kant it cannot be based on such a feeling and can be based only on pure practical reason. But the difference is not as great as Schopenhauer makes it seem, because for him compassion is supposed to arise from metaphysical insight into the unity of all being, thus from (...) pure if theoretical reason, while for Kant pure practical reason works only by effecting a feeling of respect (in the works) or by cultivating, i.e. affecting, natural dispositions to moral feeling (in the works). I argue that Kant's is the more realistic theory on this point. (shrink)

The idea of a final end of human conduct – the highest good – lies at the centre of important parts of Kant’s philosophy, such as his moral theory, his philosophy of religion, his views on the historical progress of the human species, and his conception of human rationality. This collection of new essays attempts to re-evaluate the doctrine of the highest good and to determine its relevance for contemporary philosophy.

Kant’s claims about supersensible objects, and his account of the epistemic status of such claims, remain poorly understood, to the detriment of our understanding of Kant’s metaphysical and epistemological system. In the Critique of Practical Reason, and again in the Critique of Judgment, Kant claims that we have practical cognition (Erkenntnis) and knowledge (Wissen) of the moral law and of our supersensible freedom; that this cognition and knowledge cohere with, yet go beyond the limits of, our theoretical cognition; and that (...) this knowledge grounds rational belief (Vernunftglaube) in the existence of God, the immortality of our soul, and the real possibility of the “highest good.” This essay untangles some of these claims about practical cognition, practical knowledge, and practical belief and their relation to Kant’s account of theoretical cognition and theoretical knowledge. There is a core conception of cognition and knowledge underlying the accounts of theoretical cognition and practical cognition, which allows for a principled distinction between cases of practical knowledge and practical belief. Kant’s doctrine of the “fact of reason” turns out to be crucial to his claims about legitimacy of and distinction between the two forms of practical cognition, one which constitutes knowledge and another which cannot.

This critical survey of recent work on Kant's doctrine of the fact of reason and his doctrine of the practical postulates (of freedom, God, and immortality) assesses the implications of these doctrines for the debate about realism and antirealism in Kant's moral philosophy. Section 1 briefly surveys some salient considerations from the first Critique and Groundwork. In section 2, I argue that recent work on the role, content, "factual" nature, and epistemic status of the fact of reason does not support (...) an anti-realist interpretation of Kant's ethics. In section 3, I argue that recent work on the derivation and epistemic and ontological status of the practical postulates does not support an anti-realist interpretation of Kant's ethics. (shrink)

This volume is the first ever English translation of Kant's last major work, the so-called Opus Postumum, a work Kant himself described as his 'chef d'oeuvre' and as the keystone of his entire philosophical system. It occupied him for more than the last decade of his life. Begun with the intention of providing a 'transition from the metaphysical foundations of natural science to physics,' Kant's reflections take him far beyond the problem he initially set out to solve. In fact, he (...) reassesses a whole series of fundamental topics of transcendental philosophy: the thing in itself, the nature of space and time, the concept of the self and its agency, the idea of God, and the unity of theoretical and practical reason. Though never completed, the text reaches a logical albeit not fully developed, conclusion. (shrink)

This paper revisits the concept of autonomy and tries to elucidate the fundamental insight that freedom and law cannot be understood through their opposition, but rather have to be conceived of as conditions of one another. The paper investigates the paradigmatic Kantian formulation of this insight and discusses the diagnosis that the Kantian idea might give rise to a paradox in which autonomy reverts to arbitrariness or heteronomy. The paper argues that the fatal version of the paradox can be defused (...) if we avoid the legalistic model of autonomy and rather turn to the model of participation in a practice. This leads to a dialectical understanding of the idea of autonomy that preserves the insight that freedom and law are mutually conditioning and simultaneously reveals that they remain in irresolvable tension with one another.

The goal of this study is to reconstruct and evaluate the systematic role of Kant's views on history within his ‛critical' philosophy. Kant's philosophy of history has been neglected in the literature, largely due to the widespread though mistaken perception that it is at odds with central assumptions of Kant’s ‘critical’ thought. I discuss Kant's most important texts on history and examine the relationship between Kant's view of history and the central tenets of his Critiques (in particular, Kant's conception of (...) teleology, his notion of an 'interest of reason,' and the problem of the possibility of the highest good). I argue that Kant's philosophy of history should be seen as an integral (though not entirely unproblematic) part of his mature philosophy. I show this in part by correcting the standard view of Kant's philosophy of history, and in part by highlighting hitherto neglected aspects of his critical philosophy. (shrink)

Many commentators hold that in addition to the categorical imperative of morality, Kant also posits an objective law of non-moral practical rationality, 'the' Hypothetical Imperative. On this view, the appeal to the Hypothetical Imperative increases the dialectical options that Kantians have vis-a-vis Humean skepticism about the authority of reason, and it allows for a systematic explanation of the possibility of non-moral weakness of will. I argue that despite its appeal, this interpretation cannot be sustained: for Kant the only objective, universally (...) valid a priori principle of practical reason that governs transcendentally free agents is the moral law. All non-moral practical rules are mere “precepts” that lack genuine objectivity, certainty, and intersubjective validity. I suggest that for Kant the rejection of the possibility of non-moral practical laws plays an important part in his argument for the supreme rational authority of moral norms over prudential precepts of happiness. (shrink)

I examine what Kant means when he appeals to different "standpoints". I argue that Kant seeks to contrast an empirical, anthropocentric standpoint with a normative, more than human standpoint. Against common interpretations, I argue that the normative standpoint is not confined to practical reason, since theoretical reason is concerned with what ought to be as well. Finally, I defend the coherence of Kant’s distinction against important objections.

Kant's account of “precepts of prudence” raises a striking interpretive puzzle. On the one hand, he presents such precepts as normative-practical rules; on the other hand, he relegates them to theoretical philosophy. I argue that to render these two strands coherent, we must assume that our empirical nature is a source of normativity for us: prudence is normative for us just because we have an “unconditional” empirical desire for obtaining happiness, a maximum of pleasant sensations. Since rules of prudence cognize (...) the means for causing a state of affairs that we desire and value insofar as we are receptive natural beings, these rules do not presuppose the active self-legislation of practical reason. Hence they belong to the theoretical cognition of nature. (shrink)

The use of the English word “reason” in all of these contexts, and the way we translate equivalent terms from other languages, suggests a connection, but what exactly is it? Aristotle and Kant’s conception of what practical reasons are, I believe, can help us to answer this question, by bringing out what is distinctive, and distinctively active, about acting for a reason. That, at least, is what I am going to argue.

This essay examines one of the most obscure and controversial tenets of Kant’s critical philosophy, his claim in the Critique of Practical Reason that the moral law is immediately and unquestionably valid as an a priori fact of reason (Factum der Vernunft). This argument curiously inverts Kant’s earlier stance in the Groundwork of the Metaphysics of Morals, in which he justifies the reality of the categorical imperative through a much more cautious and qualified authentication of transcendental freedom. Against constructivist readings (...) which tend to downplay the justificatory burden of the Factum, I claim that Kant’s position is best understood as a transcendental argument. In other words, he argues from a given or assured conditioned, consciousness of binding moral obligation, to the sole condition of its possibility in transcendental freedom. In order to rebut the standard objections prompted by this line of interpretation, I emphasize the technical function of Kant’s Factum as both a deed (Tat) and product (Tatsache) of practical reason.

Problems and Postulates: Kant on Reason and Understanding ALISON LAYWINE THE PURPOSE OF THIS PAPER is to think anew Kant's conception of reason and understanding, the relation between these two faculties and the principles that govern them. I am chiefly interested in the contributions of reason and under- standing to the advancement of knowledge. Hence the focus of my paper, so far as reason itself is concerned, is the theoretical rather than the practical employment of this faculty. On the other (...) hand, I think it is useful and fair to say, on Kant's account, that theoretical reason is itself practical -- at least to the extent that we regard scientific enquiry as some kind of activity, namely a research activity, involving practices such as proof and experimentation, under- taken for the sake of a certain end, namely, the acquisition of knowledge. One of Kant's concerns in the Critique of Pure Reason is to explain how this activity can be profitably pursued. To meet this concern, Kant must explain first of all how we set research goals for scientific enquiry. For without any such goals, Susan Neiman's book, The Unity of Reason , was the original stimulation for this paper. . I am more indebted to Susan.. (shrink)

There can be no doubt that Kant thought we should be reflective: we ought to care to make up our own minds about how things are and what is worth doing. Philosophical objections to the Kantian reflective ideal have centred on concerns about the excessive control that the reflective person is supposed to exert over her own mental life, and Kantians who feel the force of these objections have recently drawn attention to Kant’s conception of moral virtue as it is (...) developed in his later work, chiefly the Metaphysics of Morals. Melissa Merritt’s book is a distinctive contribution to this recent turn to virtue in Kant scholarship. Merritt argues that we need a clearer, and textually more comprehensive, account of what reflection is, in order not only to understand Kant’s account of virtue, but also to appreciate how it effectively rebuts long-standing objections to the Kantian reflective ideal.

My project is to reconsider the Kantian conception of practical reason. Some Kantians think that practical reasoning must be more active than theoretical reasoning, on the putative grounds that such reasoning need not contend with what is there anyway, independently of its exercise. Behind that claim stands the thesis that practical reason is essentially efficacious. I accept the efficacy principle, but deny that it underwrites this inference about practical reason. My inquiry takes place against the background of recent Kantian metaethical (...) debate — each side of which, I argue, correctly points to issues that need to be jointly accommodated in the Kantian account of practical reason. The constructivist points to the essential efficacy of practical reason, while the realist claims that any genuinely cognitive exercise of practical reason owes allegiance to what is there anyway, independently of its exercise. I argue that a Kantian account of respect for persons (“recognition respect”) suggests how the two claims might be jointly accommodated. The result is an empirical moral realism that is itself neutral on the received Kantian metaethical debate. (shrink)

Little extended attention has been given to Kant's notion of self-conceit, though it appears throughout his theoretical and practical philosophy. Authors who discuss self-conceit often describe it as a kind of imperiousness or arrogance in which the conceited agent seeks to impose selfish principles upon others, or sees others as worthless. I argue that these features of self-conceit are symptoms of a deeper and more thoroughgoing failure. Self-conceit is best described as the tendency to insist upon one to oneself or (...) to others s will or inclinations upon others, and more centrally the tendency to reconstruct evidence and rationalize so that one may be convinced of one’s own virtue. While the conceited agent may ultimately impose her judgement upon others, she does so in order to preserve her delusion of virtue. (shrink)

Moral realism faces two worries: How can we have knowledge of moral norms if they are independent of us, and why should we care about them if they are independent of rational activities they govern? Kantian constitutivism tackles both worries simultaneously by claiming that practical norms are constitutive principles of practical reason. In particular, on Stephen Engstrom’s account, willing involves making a practical judgment. To will well, and thus to have practical knowledge (i.e., knowledge of what is good), the content (...) of one’s will needs to conform to the formal presuppositions of practical knowledge. Practical norms are thus constitutive of practical knowledge. However, I will argue that the universality principles from which Engstrom derives the formal presuppositions of practical knowledge are reflectively and psychologically unavailable. As a result, they cannot help Kantian constitutivism provide an answer to moral realism's worries. (shrink)

Kant wants to show that freedom is possible in the face of natural necessity. Transcendental idealism is his solution, which locates freedom outside of nature. I accept that this makes freedom possible, but object that it precludes the recognition of other rational agents. In making this case, I trace some of the history of Kant’s thoughts on freedom. In several of his earlier works, he argues that we are aware of our own activity. He later abandons this approach, as he (...) worries that any awareness of our activity involves access to the noumenal, and thereby conflicts with the epistemic limits of transcendental idealism. In its place, from the second Critique onwards, Kant argues that we are conscious of the moral law, which tells me that I ought to do something, thus revealing that I can. This is the only proof of freedom consistent with transcendental idealism, but I argue that such an exclusively first-personal approach precludes the recognition of other rational agents. I conclu..

Die noch im "Anhang zur transzendentalen Dialektik" der Kritik der reinen Vernunft vorgenommene transzendentale Deduktion der Ideen - von Kant als "die Vollendung des kritischen Geschäftes der reinen Vernunft" (B 698) bezeichnet - wird als Reaktion gegen ein zuvor bedrohlich auftretendes Mannigfaltiges der Erfahrung interpretiert. Als Stärkung der totalisierenden Funktionen der Vernunft entspricht diese Maßnahme zwar der in der Kritik entwickelten Theorie der Erfahrung, gefährdet aber zugleich die Balance zwischen Mannigfaltigkeit und Einheit der Erfahrung. In einem alternativen, in der Kritik (...) der Urteilskraft enthaltenen Lösungsversuch setzt Kant an die Stelle einer Ausrichtung auf die Vernunftideen (Seele, Welt und Gott) die Orientierung am Prinzip der Zweckmäßigkeit. Wenngleich diese Teleologisierung der im "Anhang zur transzendentalen Dialektik" aufgetretenen Problematik gerechter wird, führt sie im Resultat nicht über ihn hinaus. (shrink)

En el presente artículo se arriesga una nueva interpretación del concepto kantiano de autonomía, abordándolo desde una perspectiva “heterónoma”. En efecto, sin soslayar la interpretación ya clásica de aquél se indaga sobre la posibilidad de pensarlo como tributario de una heteronomía que señala de alguna manera a la autonomía una dignidad sobre la cual ésta no puede tener prácticamente ninguna injerencia. Se pone de relieve así pues el hecho de que esta dignidad inviolable marca una diferencia práctica más radical que (...) la identidad lógica sobre la que se basa la autonomía y sobre la que descansa la ontología en cuanto tal.

It is commonly held that Kant ventured to derive morality from freedom in Groundwork III. It is also believed that he reversed this strategy in the second Critique, attempting to derive freedom from morality instead. In this paper, I set out to challenge these familiar assumptions: Kant’s argument in Groundwork III rests on a moral conception of the intelligible world, one that plays a similar role as the ‘fact of reason’ in the second Critique. Accordingly, I argue, there is no (...) reversal in the proof-structure of Kant’s two works. (shrink)
