Where Rawls’s The Law of Peoples addresses war and the use of force then his position has often been identified closely with Walzer’s restatement of just war theory, as both positions appear to take nation-states, and the conflicts between them, to be the bedrock of the international system. On the other hand, Kant’s notion of a peaceful federation of states presents us with the notion of a world without war and where the international system is transformed. This article argues that Rawls’s account of the use of force is better understood if we read it with an eye to its resonances with Kant rather than with Walzer. Doing so rewards us with a clearer understanding of central aspects of Rawls’s account of just war and vision of international politics.

This article develops an account of the nature and limits of the state’s legislative authority that closely attends to the challenge of harmonizing Kant’s ethical and juridical theories. It clarifies some key Kantian concepts and terms, then explains the way in which the state’s three interlocking authorities – legislative, executive, and judicial – are metaphysically distinct and mutually dependent. It describes the emergence of the Kantian state and identifies the preconditions of its authority. Then it offers a metaphysical model of the Kantian state and uses it to argue that the activity of juridical lawgiving is an act of the omnilateral will itself. Legislative authority is limited in the sense that it does not include the capacity to create juridical laws that are conceptually incompatible with the idea of universal external freedom. I argue that my proposed account of the legislative authority is wholly consistent with that authority’s exclusive lawgiving capacity and does not threaten the possibility of ‘distributive justice’ – the legal finality that is the sine qua non of a civil condition.

My aim in this article is to provide an account of practical judgement, for Kant, that situates it within his theory of judgement as a whole – particularly, with regards to the distinction between the determining and reflecting use of judgement. I argue that practical judgement is a kind of determining judgement, but also one in which reflecting judgement plays a significant role. More specifically, I claim that practical judgement arises from the cooperation of the reflecting power of judgement with the faculty of reason – the former assisting the latter in the application of its principle. I conclude by considering a possible role for feeling in practical judgement.

Schopenhauer's claim that the essence of the world consists in Wille encounters well-known difficulties. Of particular importance is the conflict of this metaphysical claim with his restrictive account of conceptuality. This paper attempts to make sense of Schopenhauer's position by restoring him to the context of post-Kantian debate, with special attention to the early notebooks and Fourfold Root of the Principle of Sufficient Reason. On the reconstruction suggested here, Schopenhauer's philosophical project should be understood in light of his rejection of post-Kantian metaphilosophy and his opposition to German Idealism.

Kant’s practical philosophy, Rawls’s theory of justice and contemporary human rights thinking are landmarks in liberal discussions of justice. Each forms part of a powerful tradition of political thought, and although their substantive accounts of justice diverge at many points, they also overlap in substantial ways. This article focuses not on their substantive claims about justice, or about other ethical standards, but on their differing views of the questions to be addressed, on their proposed justifications for standards of justice, and on a limited range of questions about interpreting and institutionalizing those standards.

I propose that we interpret Kant’s argument from incongruent counterparts in the 1768 article ‘Concerning the Ultimate Ground of the Differentiation of Directions in Space’ in light of a theory of dynamic absolute space that he accepted throughout the 1750s and 1760s. This force-based or material conception of space was not an unusual interpretation of the Newtonian notion of absolute space. Nevertheless, commentators have continually argued that Kant’s argument is an utter failure that shifts from the metaphysics of space to its epistemology, because he has no way to connect ‘directionality’ and ‘handedness’ to absolute space. This supposed failure is based on an understanding of absolute space in purely mathematical terms and as an absolute void that lacks any qualitative or dynamic features. If we recognize that Kant held that space had an intrinsic directional asymmetry then his argument successfully connects incongruent counterparts to absolute space. The presence of this notion in Kant’s pre-Critical thought is rarely noted, and its necessity in understanding his incongruence argument is novel.

This article explores the practical approach to global justice advocated by the cosmopolitan political theorists Pogge, Beitz and Buchanan. Using a comparative exposition it outlines their reliance on international law and on human rights law in particular. The essay explores the neo-Kantian influence on the practical approach and offers an original critique of this trend in contemporary international political theory.

The second edition of the Critique of Pure Reason (hereafter, Critique) contains several major and myriad minor emendations. The revision of the mode of presentation is apparent in four sections of the Critique: the Aesthetic; the Doctrine of the Concepts of the Understanding; the Principles of Pure Understanding; and ‘the paralogisms advanced against rational psychology’ (Bxxxviii). A new refutation of psychological idealism begins at B274. Perhaps most importantly, a new Preface frames the Critique.

It is widely supposed that the principal task of Kant's Critique of Pure Reason is to carry out some kind of analysis of experience. Commentators as profoundly at odds on fundamental points of interpretation as P. F. Strawson and Patricia Kitcher share this supposition. In a letter to J. S. Beck, Kant seems to endorse this view himself, referring to some unspecified stretch of the Critique as an ‘analysis of experience in general’. The idea that the Critique is engaged in an analysis of experience accords well with an attractive conception of Critical philosophy as making something explicit that is generally only implicit in our cognitive lives. After all, the categorical imperative is no innovation of Kant's practical philosophy, but rather is meant to be revealed as the animating principle of ‘ordinary moral rational cognition’. Likewise, the principles revealed in Kant's theoretical philosophy should be nothing other than the principles that necessarily animate ordinary empirical cognition; and Kant says that experience is, or is a mode of, empirical cognition. For this reason, it is undeniably compelling to think of the Critique as offering some kind of analysis of experience.

It is commonly thought that the distinction between subjectively valid judgements of perception and objectively valid judgements of experience in the Prolegomena is not consistent with the account of judgement Kant offers in the B Deduction, according to which a judgement is ‘nothing other than the way to bring given cognitions to the objective unity of apperception’. Contrary to this view, I argue that the Prolegomena distinction maps closely onto that drawn between the mathematical and dynamical principles in the System of Principles: Kant’s account of the Prolegomena distinction strongly suggests that it is the Analogies of Experience that make it possible for judgements of perception to give rise to judgements of experience. This means that judgements of perception are objectively valid with regard to the quantity and quality of objects, and subjectively valid with regard to the relation they posit between objects. If that is the case, then the notion of a judgement of perception is consistent with the B Deduction account of judgement.

In this article I press four different objections on Forst’s theory of the ‘Right to Justification’. These are (i) that the principle of justification is not well-formulated; (ii) that ‘reasonableness and reciprocity’, as these notions are used by Rawls, are not apt to support a Kantian conception of morality; (iii) that the principle of justification, as Forst understands it, gives an inadequate account of what makes actions wrong; and (iv) that, in spite of his protestations to the contrary, Forst’s account veers towards a version of moral realism that is prima facie incompatible with Kantian constructivism. I then evaluate Forst’s theory in the light of a distinction made by Sharon Street between restricted and unrestricted constructivism. I show that Forst has reason to deny that it is either the one or the other, but he is not able to show that it is both or neither. I conclude that the arguments Forst advances in support of his constructivist theory of the right to justification entail that it is a metaphysical and comprehensive conception in the relevant, Rawlsian sense. Forst’s theory of the right to justification therefore fails to fulfil one of the main stated aims.

In recent years Nick Zangwill has gone a long way in championing a moderate aesthetic formalism in an attempt to accommodate those objects that many of us call beautiful despite their lack of any formal beauty. While there is some dispute in the literature about the extent to which Kant can be interpreted as an aesthetic formalist, the appeal of his famous distinction between free and dependent beauty should present a fairly natural ally for Zangwill's project. Indeed, such an alliance has been expressed by Zangwill, who first reaches for this ‘invaluable but misunderstood and underappreciated distinction’ in his ‘Feasible aesthetic formalism’ (1999: 613). Here, Zangwill claims that this essential distinction can be cut loose from Kant's terminology and views about aesthetic judgement. More recently he expresses more strongly that ‘Kant was also a moderate formalist, who opposes extreme formalism when he distinguished free and dependent beauty in §16 of the Critique of Judgement’ (2005: 186n). Yet, a decade on from the initial suggestion, there has been little further exploration or elucidation of this move, or indeed this potential characterization of Kant's aesthetics. It is the aim of this paper to begin to address that deficiency by identifying the extent to which a moderate formalist position is available in Kant's aesthetic. I will suggest that Kant's account does not require substantial modification in order to cast him as a moderate formalist. Taking the time to isolate the plausible grounds for characterizing Kant's aesthetic in this way, this discussion will enable us to explore some of the rival interpretations of his work such that we may also identify the kind of Kantian the moderate formalist is likely to be.
