Hume and contemporary Humeans contend that moral sentiments form the sole and sufficient basis of moral judgments. This thesis is criticised by appeal to Hume’s theory of justice, which shows that basic principles of justice are required to form and to maintain society, which is indispensable to human life, and that acting according to, or violating, these principles is right, or wrong, regardless of anyone’s sentiments, motives or character. Furthermore, Hume’s theory of justice shows how the principles of justice are (...) artificial without being arbitrary. In this regard, Hume’s theory belongs to the unjustly neglected modern natural law tradition. Some key merits of this strand in Hume’s theory are explicated by linking it to Kant’s constructivist method of identifying and justifying practical principles (à la O’Neill), and by showing how and why Hegel adopted and further developed Kant’s constructivism by re-integrating it with Hume’s central natural law concern with our actual social practices. (Slightly revised English translation by the author of „Von der Konvention zur Sittlichkeit. Humes Begründung einer Rechtsethik aus nach-Kantischer Perspektive“, on which see below.). (shrink)

‘Universalist’ moral principles have fallen into disfavour because too often they have been pretexts for unilateral impositions upon others, whether domestically or internationally. Too widely neglected has been Kant’s specifically Critical re-analysis of the scope and character of rational justification in all non-formal domains, including the entirety of epistemology and moral philosophy, including both justice and ethics. Rational judgment is inherently normative because it is in part constituted by our self-assessment of whether the considerations we now integrate into a candidate (...) judgment have been integrated as they ought, so as to form a cogent, justifiable judgment. Constitutive of this self-assessment is that rational judgments must be based upon considerations which can be communicated to all others, such that they too can assess them as sufficiently cogent justification; also constitutive of this rational self-assessment is that we actually engage with others who do assess our judgments. Kant’s Critical principles rule out in principle any unilateral imposition upon others, whether in cognition or morals. Using Kant’s Critical principles and methods in connection with ‘practical anthropology’ and the enormously important domain of acquired rights and obligations shows how Kant had already justified fundamentally universal principles of justice which can be institutionalised in variously distinctive cultures, and which form the proper bases for our acquired, specifically social rights and obligations, including those of friendship and community.

This article examines Kant’s theory of property through a comparative analysis of Gottfried Achenwall’s justification of ownership rights. I argue that at the core of Achenwall’s and Kant’s understanding of ownership rights lies the idea that rights are to be acquired through a juridical act (factum iuridicum, rechtlichen Act) of the will. However, while Achenwall thinks of this act as emerging from a private will, Kant holds that rights and obligations can only be brought about by an act of the (...) general will. By contrasting these two views, I aim to illuminate one of the main features of Kant’s theory of property, namely, that ownership rights are only possible in a rightfully constituted state. I conclude with a suggestion regarding Kant’s view of the notion of ‘provisional’ possession in the state of nature. (shrink)

We can observe a connection between some serious environmental problems caused by the overexploitation of environmental resources and the particular conceptions of property rights that are claimed to hold with regard to these resources. In this paper, I investigate whether Kant’s conception of property rights might constitute a basis for justifying property regimes that would overcome some of these environmental problems. Kant’s argument for the right to property, put forward in his Doctrine of right, is complex. In Section 2, I (...) attempt an interpretation. Section 3 works out the defining characteristics of the conception of property rights that Kant’s argument establishes and investigates their implications for determining property regimes in environmental resources. Kant proposes a minimalist notion of the right to property as a triadic relation between persons with regard to an object, justified only on the condition that it is universalizable in the given circumstances. I argue that this notion offers a promising account for determining property relations with regard to environmental resources. By way of illustration, in Section 4, I focus on an example of Kantian property rights in one type of environmental resource: the marine fisheries. (shrink)

En este trabajo se reflexiona en torno al concepto de _usucapio_ del §33 de la _Metafísica de las costumbres_. Para ello se piensan las condiciones y relación entre la posesión sensible y de la posesión inteligible o jurídica sin caer en una mera implicación causal. La posibilidad de uso de los objetos como garantía de la libertad legitimaría el principio de la usucapio, de la que, además, dice Kant que las dificultades que entraña la convierten en un concepto contradictorio.

La posesión común de la tierra fue una idea prominente en la filosofía moderna del siglo xvii. En este artículo, sostendré que Kant no sólo propuso una versión secular de la posesión común de la tierra, sino que también se diferenció de forma radical de la concepción iusnaturalista de sus predecesores. Propongo que la revisión kantiana del derecho cosmopolita se dirige al mismo problema que el derecho de necesidad de Grocio, a saber, la implausibilidad de asumir derechos adquiridos absolutos cuando (...) esto contradice la razón por la que se introducen esos mismos derechos. Sin embargo, mientras que Grocio pretendió excusar violaciones de la propiedad privada en casos de necesidad, Kant limitó su discusión al derecho de rechazar la entrada de personas en un territorio. Muestro que para Kant, negar la ocupación del espacio que puede salvar la vida a otro ser humano que está, en principio, tan legitimado como cualquier otro a tener un derecho en la tierra está en contradicción con la justificación misma del derecho territorial de los Estados. Esto se debe a que el permiso para controlar el territorio y el derecho de los visitantes involuntarios a ser admitidos en una región están basados en el mismo fundamento legal o Rechtsgrund, a saber, la comunidad original de la tierra.
