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.

This paper offers a new interpretation of Kant's relationship with skepticism in the Groundwork for the Metaphysics of Morals. My position differs from commonly held views in the literature in two ways. On the one hand, I argue that Kant's relationship with skepticism is active and systematic (contrary to Hill, Wood, Rawls, Timmermann, and Allison). On the other hand, I argue that the kind of skepticism Kant is interested in does not speak to the philosophical tradition in any straightforward sense (...) (contrary to Forster and Guyer). On my reading, Kant takes up a skeptical method in the Groundwork as a way of exposing certain obstacles in our ordinary and philosophical thinking about morality. The central obstacle he is interested in is practical in character, arising from a natural tendency we have to rationalize against the moral law. In attempting to resolve this tendency, I argue, the Groundwork turns out to have a profoundly educative task. (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)

Over the last two decades, Kant’s name has become closely associated with the “constitutivist” program within metaethics. But is Kant best read as pursuing a constitutivist approach to meta- normative questions? And if so, in what sense? In this essay, I’ll argue that we can best answer these questions by considering them in the context of a broader issue – namely, how Kant understands the proper methodology for philosophy in general. The result of this investigation will be that, while Kant (...) can indeed be read as a sort of constitutivist, his constitutivism is ultimately just one instance of a much more general approach to philosophy – which treats as fundamental our basic, self-conscious rational capacities. Thus, to truly understand why and how Kant is a constitutivist, we need to consider this question within the context of his more fundamental commitment to “capacities-first philosophy”. (shrink)

This article explores a set of questions about the ‘idea of freedom’ that Kant introduces in the fourth paragraph of Groundwork III. I develop a reading that supports treating it as a normative notion and brings out its normative content in some detail. I argue that we should understand the idea as follows: that it is a general feature of reasoning and judgement that it understands itself to be a correct or sound application of the normative standards of the relevant (...) domain of cognition, not influenced by irrelevant or external factors. Reasoning and judgement are thus normatively committed to these standards of correctness. A second and related concern is to explore connections between the idea of freedom and Kant’s conception of autonomy and to identify different points at which autonomy plays a role in the argument of Groundwork III. In the final section, I mine the idea of freedom for a set of normative commitments specific to rational agency that play a foundational role in Kant’s moral conception. (shrink)

A ciência e a tecnologia ocupam um lugar fundamental e insubstituível na construção da realidade sociocultural atual. Estão ligadas ao destino da vida humana, sendo que o ser do homem está marcado cada vez mais pela ciência e a depender dela em sua efetivação. Porém, do expressivo avanço científico tecnológico advém um dilema que penetra o âmago da realidade sociocultural humana. O homem contemporâneo, por um lado, sente-se orgulhoso de ter superado a pura facticidade existencial de uma vida simplesmente inserida (...) em crenças tradicionais, assumindo, por sua vez, a consciência de seu processo de autoconstrução e uma vida eminentemente racionalizada, mas, por outro, ele não consegue superar e ultrapassar a vigência histórica da normatividade da comunidade humana histórica na qual ele está inserido. Contudo, percebendo-se que o progresso científicotecnológico avança rapidamente, exigindo, pois, um novo espectro do raciocínio ético da ação, dimensão esta desconhecida a todas as formas precedentes de ação e reflexão, constata-se certo descompasso entre os avanços da ciência e da tecnologia com o alcance da reflexão e da práxis do agir ético, especialmente, depois que a ciência e a técnica ampliaram a margem de liberdade e autonomia a ponto de ser possível afirmar, depois de um desencantamento da natureza externa, agora, uma espécie de um novo encantamento com a natureza interna. À luz dessa nova conjuntura sociocultural, tem-se o propósito de remontar à Fundamentação da metafísica dos costumes de Kant na segunda formulação do imperativo categórico, humanidade como fim, a fim de investigar se a mesma, por um lado, pode ser aproximada à compreensão do fim último e do fim final no processo de moralização na Crítica do juízo, e, por outro lado, se tal formulação pode ser ancoradouro razoável à discussão ética contemporânea de espectro em nentemente científico.

Este texto busca mostrar algunos aspectos de continuidad entre las concepciones de la acción intencional de Kant y Hegel. Esos aspectos son la base de otros conocidos elementos de ruptura que hay entre ellos. Como en las últimas décadas el problema de la concepción de ambos autores en torno a este punto ha sido investigado por múltiples estudiosos, me concentraré fundamentalmente en un punto que no ha sido suficientemente tratado: el modo en que ambos autores conciben la naturaleza de la (...) acción frente a lo que se podría considerar el enfoque dominante al día de hoy: la concepción que llamaré causal-reductiva. Luego de ello sugeriré que en el marco de esta oposición a la concepción causal reductiva surge una divergencia profunda entre Kant y Hegel. (shrink)

The contradiction in conception test is one of two tests posed by Kant’s Formula of the Law of Nature. This article proposes a new interpretation of this test: a causal-teleological version of the Logical Contradiction Interpretation. Its distinctive feature is that it identifies causal and teleological implications in the thought of a universal law of nature. A causal-teleological version of LCI has two advantages. While the established view of the Groundwork’s applications of the CC test is a hybrid view that (...) treats the Groundwork’s arguments as different in kind, a causal-teleological version of LCI unifies the Groundwork’s applications of the CC test. Relatedly, a causal-teleological version of LCI provides a solution to the problem of how the CC test can confirm the impermissibility of a self-directed maxim. (shrink)

Of the questions concerning the many great minds of the European Enlightenment, the question of what constitutes right and proper government perhaps had the most enduring influence on the world stage. Both Thomas Jefferson and Immanuel Kant attempted to answer the question of what constitutes right government, in particular by basing the system upon the idea of human freedom as an inalienable right. This project is an attempt to compare the systems proposed by these two authors, as well as to (...) critique each on its ability to protect and foster individual freedom. It is my opinion that neither manages to do what it is constructed to do, as each fails to fully protect individual freedom, and each has as part of it a component which conflicts with individual freedom.
