Kants Kritik der praktischen Vernunft (1788) steht zu Unrecht oft im Schatten der Kritik der reinen Vernunft und der Grundlegung zur Metaphysik der Sitten. Tatsächlich sind die Grundelemente der Kantischen Moralphilosophie im Gegensatz zu vielen Thesen der ersten Kritik bis heute weitgehend anerkannt, und erst der Nachweis der zweiten Kritik, dass Freiheit wirklich ist, macht "den Schlussstein von dem ganzen Gebäude eines Systems der reinen, selbst der spekulativen Vernunft aus". Entlang der Stichworte reiner Wille, gesetzgebende Form der Maxime, transzendentale Freiheit, (...) Autonomie und Faktum der Vernunft zeigt Kant in der "Analytik", dass reine Vernunft "für sich" praktisch sein, nämlich den Willen bestimmen kann. Die "Dialektik" sichert den Ideen von der Existenz Gottes und der Unsterblichkeit der Seele objektive Realität und untersucht das Verhältnis von theoretischer und praktischer Vernunft. Die "Methodenlehre" schließlich skizziert eine Theorie moralischer Erziehung, die für den heutigen Ethikunterricht noch aktuell ist. Die zwölf Beiträge dieses kooperativen Kommentars, der anlässlich des 300. Jubiläums Immanuel Kants in einer 3., überarbeiteten Auflage erscheint, rekonstruieren die Argumente eines Schlüsseltextes der Moralphilosophie und prüfen die sachliche Überzeugungskraft.

In the Critique of Practical Reason, Kant presents the moral law as the sole ‘fact of pure reason’ that neither needs nor admits of a deduction to establish its authority. This claim may come as a surprise to many readers of his earlier Groundwork of the Metaphysics of Morals. In the last section of the Groundwork, Kant seemed to offer a sketch of just such a ‘deduction of the supreme principle of morality’ . Although notoriously obscure, this sketch shows that (...) Kant hoped to base the moral law in the freedom that rational agents can claim as members of the ‘intelligible world’ that transcendental idealism makes available to us. In contrast, the second Critique abandons all aspirations of deriving morality from more basic notions of freedom and practical rationality. (shrink)

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)

O sumo bem, tal qual apresentado na CRPr, consiste na união da moralidade com a felicidade. Como esta ligação não pode ser assegurada necessariamente pelo próprio homem durante a sua finita e imperfeita existência, resta que se existe uma síntese; a mesma apenas pode ser elucidada em um suposto juízo sintético a priori que possa unir a vida terrena virtuosa com a felicidade post mortem que é o que parece exigir uma síntese desta natureza. Frente a esta questão, defendemos que (...) há boas razões para sustentar que o sumo bem é um objeto necessário da razão prática pura com base no pressuposto metafísico da constituição peculiar da faculdade de apetição de seres racionais finitos sem comprometer, com isso, o caráter de universalidade desta pretensão. O artigo culmina apontando alguns pontos de vista de aproximação da figura do sumo bem deixando claro que não há uma prova cabal; mas a fecundidade de um conjunto de perspectivas teóricas e práticas que permitem uma série de aproximações desse conceito até o ponto em que, por razões bem fundamentadas, não parece mais razoável sustentá-lo apenas como um ideal meramente dialético.

Abstract: In this paper I consider the significant but generally overlooked role that the French Revolution played in the development of German Idealism. Specifically, I argue that Reinhold and Fichte's engagement in revolutionary political debates directly shaped their interpretation of Kant's philosophy, leading them (a) to overlook his reliance upon common sense, (b) to misconstrue his conception of the relationship between philosophical theory and received cognitive practice, (c) to fail to appreciate the fundamentally regressive nature of his transcendental argumentative strategy, (...) and, ultimately, (d) to seek to deduce his philosophy from a single first-principle, one grounded in the immediate awareness of the subject's mental life.

Kant holds that the applicability of the moral ‘ought’ depends on a kind of agent-causal freedom that is incompatible with the deterministic structure of phenomenal nature. I argue that Kant understands this determinism to threaten not just morality but the very possibility of our status as rational beings. Rational beings exemplify “cognitive control” in all of their actions, including not just rational willing and the formation of doxastic attitudes, but also more basic cognitive acts such as judging, conceptualizing, and synthesizing.

El primer objetivo de este artículo es presentar una interpretación del tercer capítulo de la Fundamentación para establecer dos puntos: primero, que Kant ofrece ahí una deducción de la libertad/moralidad como autonomía a partir de premisas provenientes exclusivamente de la filosofía teórica. Segundo, que Kant ofrece también una deducción distinta del imperativo categórico. El segundo objetivo del artículo es examinar y criticar en detalle un paso crucial en estas deducciones, a saber, la inferencia de la existencia noumenal del sujeto como (...) voluntad libre a partir de la espontaneidad especulativa de la razón. Muestro que Kant mismo rechaza esta inferencia en la edición B de la Crítica de la razón pura y argumento que esto explica el hecho de que Kant, en la Crítica de la razón práctica, abandona la deducción de la ley moral que había ofrecido previamente. Así, contra la lectura “reconciliacionista”, hay de hecho un gran cambio en la última obra. (shrink)

Is the refutation of scepticism a central objective for Kant? Some commentators have denied that the refutation of either theoretical or moral scepticism was central to Kant's concerns. Thus, in his recent book Kant and the Fate of Autonomy, Karl Ameriks rejects 'taking Kant to be basically a respondent to the skeptic'. According to Ameriks, who here has Kant's theoretical philosophy in mind,What Kant goes on to propose is that, instead of focusing on trying to establish with certainty – against (...) skepticism – that the objects of common sense exist, let alone that they have philosophical dominance, or, in contrast, on explaining that it is only the theoretical discoveries of science that determine what is objective, one can rather work primarily to determine a positive and balanced philosophical relation between the distinct frameworks of our manifest and scientific images.

This paper explains the empirical markers by which Kant thinks that one can identify moral responsibility. After explaining the problem of discerning such markers within a Kantian framework, I briefly explain Kant’s empirical psychology. I then argue that Kant’s empirical markers for moral responsibility—linked to higher faculties of cognition—are not sufficient conditions for moral responsibility, primarily because they are empirical characteristics subject to natural laws. Next, I argue that these markers are not necessary conditions of moral responsibility. Given Kant’s transcendental (...) idealism, even an entity that lacks these markers could be free and morally responsible, although as a matter of fact Kant thinks that none are. Given that they are neither necessary nor sufficient conditions, I discuss the status of Kant’s claim that higher faculties are empirical markers of moral responsibility. Drawing on connections between Kant’s ethical theory and ‘common rational cognition’, I suggest that Kant’s theory of empirical markers can be traced to ordinary common sense beliefs about responsibility. This suggestion helps explain both why empirical markers are important and what the limits of empirical psychology are within Kant’s account of moral responsibility.Keywords: Immanuel Kant; Moral responsibility; Freedom; Empirical psychology; Transcendental idealism; Reason; Common sense; Anthropology.

It is well known that Kant uses the notion of the holy will in theGroundworkso as to contrast it with the finite wills of human beings. It is less clear, however, what function this contrast is supposed to perform. I argue that one role of the holy will is to illustrate transcendental idealism’s account of the relation between moral knowledge and moral practice. The position is one intended to negotiate between ostensibly competing traditions. Kant uses the holy will as a (...) way of endorsing the metaphysical picture of the scholastic tradition’s so-called ‘ethics of freedom’, whereby the ideal of moral perfection is conceived as the perfection of one’s power of freedom to the point where one is constitutively incapable of immoral action. This position is married however with the claim that the holy will’s inaccessibility to human cognition motivates a subject-oriented moral epistemology more usually associated with Enlightenment humanism. I conclude by claiming that the nuanced role for the holy will can be understood as part of Kant’s expansion of the value of religious faith [Glaube] to the domain of practical inquiry in general.

Famously, in the second Critique, Kant claims that our consciousness of the moral law provides us with sufficient grounds for the attribution of freedom to ourselves as noumena or things-in-themselves. In this way, while Kant insists that we have no rational basis to make substantive assertions about things-in-themselves from a theoretical point of view, it is rational for us to assert that we are noumenally free from a practical one. This much is uncontroversial. What is controversial is the cognitive relation (...) to things-in-themselves that is possible from a practical point of view. Interpreters have tended to regard such “practical cognition” of things-in-themselves as a poor step-cousin of its theoretical counterpart — as a sort of mere “rational faith” unworthy of comparison with genuine theoretical knowledge or cognition. Recent work on these issues has begun to shift this picture. But this reassessment is in its early stages and remains highly controversial. My aim here is to take this tendency and push it farther than most have generally been willing to go - at least with respect to our practical self-understanding as noumenally free agents. Indeed, I believe that, far from representing an impoverished cousin of theoretical cognition and knowledge, our practical awareness of ourselves as free possesses the central marks of cognition and knowledge in Kant’s sense of these terms, albeit on practical grounds. Thus, it is no surprise that Kant is willing to speak of our consciousness of the moral law as enabling genuine cognition of noumenal freedom. (shrink)
