The interpretation of Kant's Critical philosophy as a version of traditional idealism has a long history. In spite of Kant's and his commentators’ various attempts to distinguish between traditional and transcendental idealism, his philosophy continues to be construed as committed (whether explicitly or implicitly and whether consistently or inconsistently) to various features usually associated with the traditional idealist project. As a result, most often, the accusation is that his Critical philosophy makes too strong metaphysical and epistemological claims.

In his The Revolutionary Kant, Graham Bird engages in a systematic and thorough evaluation of the traditionalist interpretation, as part of perhaps the most comprehensive and compelling defence of a revolutionary reading of Kant's thought. In the third part of this special issue, the exchanges between, on the one hand, Graham Bird and, on the other, Gary Banham, Gordon Brittan, Manfred Kuehn, Adrian Moore and Kenneth Westphal focus on specific aspects of Bird's interpretation of Kant's first Critique. More exactly, the emphasis is on specific aspects of Bird's interpretation of the Introduction, Analytic of Principles and Transcendental Dialectic of Kant's first Critique.

The second part of the special issue is devoted to discussions of particular topics in Bird's construal of the remaining significant parts of the first Critique, namely, of the Transcendental Aesthetic and the Analytic of Concepts. Written by Sorin Baiasu and Michelle Grier, these articles examine specific issues in these two remaining parts of the Critique, from the perspective of the debate between the traditionalist and revolutionary interpretation. The special issue begins with an Introduction by the guest co-editors. This provides a summary of the exchanges between Bird and his critics, with a particular focus on the debates stemming from the differences between traditional and revolutionary interpretations of Kant.

In response to critical discussions of my book, Moral Literacy, by Stephen Engstrom, Sally Sedgwick and Andrews Reath, I offer a defence of Kant's formalism that is not only friendly to my claims for the moral theory's sensitivity to a wide range of moral phenomena and practices at the ground level, but also consistent with Kant's high rationalist ambitions.

Kant insists that the use of concepts must be subject to empirical conditions if they are to have objective validity. This article analyses Kant’s principle of objective validity, focusing particularly on its application to transcendental concepts such as those of sensibility, understanding and transcendental apperception. It distinguishes between two orders of objective validity, based on Kant’s distinction between empirical and transcendental truths. Since transcendental concepts are pure concepts without spatio-temporal content, their objective validity is of the same second-order kind as that of unschematized categories. This characteristic of transcendental concepts implies that the cognitive powers picked out by them are not particular psychological mechanisms, but rather abstract functional structures. Transcendental concepts owe their objective validity to the realizability of the functional structures by empirical cognizers like humans. This relation in turn helps to explain the nature of transcendental truths.

Kant’s philosophy of natural science has traditionally concentrated on a host of issues including the role of laws of nature and teleological judgements. However, so far, the literature has made virtually no contact with the no less important tradition in Kant’s legal and political philosophy. This article explores one aspect of such connection in relation to the normative foundations of Kant’s notion of cosmopolitan right. I argue that Kant’s argument for cosmopolitan right is based on two main premises: the first is what I call the law of equilibrium, and the second is the premise of physical interaction (commercium in Latin) at work behind what Kant called the original ‘community of land’. The article argues that the relevant notion of community qua commercium should be understood in the context of Kant’s metaphysics of nature as a ‘real community of substances’ governed by a dynamical law of equality of action and reaction. This metaphysical-causal interpretive reading has far-reaching implications for the foundations of cosmopolitan right and its scope of applicability well beyond Kant’s envisaged right to universal hospitality.

Kant interpreters have contrasting views on what Kant takes to be the basis for human dignity. Several commentators have argued that human dignity can be traced back to some feature of human beings. Others contend that humans in themselves lack dignity, but dignity can be attributed to them because the moral law demands respect for humanity. I argue, alternatively, that human dignity in Kant’s system can be seen to be grounded in the reciprocal relationship between the dignity of the moral law and the dignity inherent in the human constitution. The latter includes the dignity of personhood, construed as rational inner purposiveness, and the dignity of giving oneself the law and striving to follow it.

This article discusses Luigi Caranti’s Kant’s Political Legacy, which argues, among other things, that a Kantian reconstruction of dignity can provide a foundation for human rights. Caranti’s book is one of the most powerful recent reconstructions of Kant’s political philosophy. Four main points are argued in response. First, to what extent can dignity understood as a value ground the essentially relational character of human rights claims? Second, does Caranti explain why our mere rational capacity to set moral ends has dignity rather than the realization of that capacity in a morally righteous will? Third, how can the argument provided avoid the conclusion that, because people’s capacities vary, their dignity varies too? Fourth, is Kant’s political philosophy incompatible with our modern understanding of human rights and, in particular, their function in international law and practice?

Although Kant defends a cosmopolitan ideal, his philosophy is problematically vague regarding how to achieve it, which lends support to the empty formalism charge. How Kant would respond to the crisis in Syria reveals that judgement plays too central a role, because Kantian principles lead to equally reasonable but opposite conclusions on how to weigh the duty of hospitality to refugees against a state’s duty to its own citizens, the right of prevention towards ISIS against the duty not to harm non-combatants, and the responsibility to protect the people of Syria against the duty of non-interference in its internal affairs.

At the end of §40 of the Critique of Judgement, after a discussion of the sensus communis and its connection with taste, Kant writes:

If we could assume that the mere universal communicability as such of our feeling must already carry with it an interest for us (something we are, however, not justified in inferring from the character of a merely reflective power of judgment), then we could explain how it is that we require from everyone as a duty, as it were (gleichsam), the feeling in a judgment of taste. (5: 296; 162)

The problem of Kant’s Neglected Alternative is that while his Aesthetic provides an argument that space and time are empirically real – in applying to all appearances – its argument seems to fall short of the conclusion that space and time are transcendentally ideal, in not applying to any things in themselves. By considering an overlooked passage in which Kant explains why his Transcendental Deduction is ‘unavoidably necessary’, I argue that it is not solely in his Aesthetic but more so in his Deduction where he intends to provide his argument for the transcendental ideality of space and time. His Deduction shows that space and time do not have a valid application to any things in themselves by arguing that the categories do have a valid application to everything in space and time, but that the categories do not have a valid application to any things in themselves.

Before surveying examples of Kant's transcendental psychologism, it may prove helpful to return to the model after which they are patterned: Hume's associationism. Contrary to what is often supposed, Hume did not confine his enquiries into representational origins to what exists in the mind prior to and independently of association. When the materials available pre-associationally are insufficient to yield an idea able to perform a certain prescribed function in human thought and reasoning, he then typically looked to the actions and affects of the associating imagination itself as the sources of the missing elements. The idea of cause and effect is the locus classicus. The pre-eminent function of this idea is to extend the mind's purview ‘beyond our senses’ and inform ‘us of existences and objects, which we do not see or feel’ (A Treatise of Human Nature (THN) 74).

This article explores the distinctions among European peoples’ character established in Kant’s anthropology and their connection with his politics. These aspects are neglected relative to the analysis of race between Europeans and non-Europeans, but Kant’s anthropological works portray the people of Mediterranean Europe as not capable of civilization because of the dominance of passion in their faculty of desire, which he ties to ‘Oriental’ influences in blood or government. Kant then superimposes this racialized anthropology over the historical geopolitics of Europe, obscuring the indebtedness of Northern European trade dominance to Mediterranean historical tactics and financial wealth. By relegating the Mediterranean to the margins and dismissing contentious commercial exchange in the region as mere violence spearheaded by North African corsairs, Kant gives us an elitist cosmopolitanism unable to cope with hierarchy and inequality, diminishing its potential for egalitarian global projects today.

Lucy Allais’s anti-phenomenalist interpretation of transcendental idealism is incomplete in two ways. First of all, like some phenomenalists, she is committed to denying the coherence of claims of numerical identity of appearances and things in themselves. Secondly, she fails to explain adequately what grounds the actuality of appearances. This opens the door to a phenomenalist understanding of appearances.

In §76 of the third Critique, Kant claims that an intuitive understanding would represent no distinction between possible and actual things. Prior interpretations of §76 take Kant to claim that an intuitive understanding would produce things merely in virtue of thinking about them and, thus, could not think of merely possible things. In contrast, I argue that §76’s modal claims hinge on Kant’s suggestion that God represents things in their thoroughgoing determination, including in their connection to God’s actual will. I conclude by using my interpretation to argue that §76’s modal claims do not entail Spinozism.

In the Critique of Pure Reason, Kant conceives of general logic as a set of universal and necessary rules for the possibility of thought, or as a set of minimal necessary conditions for ascribing rationality to an agent (exemplified by the principle of non-contradiction). Such a conception, of course, contrasts with contemporary notions of formal, mathematical or symbolic logic. Yet, in so far as Kant seeks to identify those conditions that must hold for the possibility of thought in general, such conditions must hold a fortiori for any specific model of thought, including axiomatic treatments of logic and standard natural deduction models of first-order predicate logic. Kant's general logic seeks to isolate those conditions by thinking through – or better, reflecting on – those conditions that themselves make thought possible.

One recent trend in Kant scholarship has been to read Kant as undertaking a project in philosophical semantics, as opposed to, say, epistemology, or transcendental metaphysics. This trend has evolved almost concurrently with a debate in contemporary philosophy of mind about the nature of concepts and their content. Inferentialism is the view that the content of our concepts is essentially inferentially articulated, that is, that the content of a concept consists entirely, or in essential part, in the role that that concept plays in a system of inferences. By contrast, relationalism is the view that this content is fixed by a mental or linguistic item's standing in a certain relation to its object. The historical picture of Kant and the contemporary debate about concepts intersect in so far as contemporary inferentialists about conceptual content often cite Immanuel Kant not only as one of the founding fathers of a tradition that leads more or less straightforwardly to contemporary inferentialism, but also as the philosopher who first saw the fatal flaws in any attempt to articulate the content of our concepts relationally.

Kant's correspondence includes a short letter from a well-wisher named Bertram. The content of the letter is as harmless as it is uninteresting: Bertram invites Kant to visit his brother's estate. ‘Do come,’ he says, ‘because the weather is so beautiful and such travel so beneficial’ (10: 182). The interest of the letter is entirely exhausted by the date: 20 May 1775. For Kant used the letter to scribble down ideas, some suggestive of themes later to emerge in the first Critique. Similarity of handwriting and train of thought suggests that these scribbles are part of a whole bundle of papers collectively known as the Duisburg Nachlaβ (R4674-4684 in volume 17 of the Academy Edition). It was supposedly Kant's practice to use letters as scrap paper shortly after receiving them. If this is true, we can date the Bertram scribbles - and, in all likelihood, the bundle as a whole - to some time in 1775. That would make the Duisburg Nachlaβ one of the few pieces of philosophical writing in Kant's own hand to come down to us from the 1770s, and the only extended piece in his hand from the middle of the decade. It offers a rare glimpse of Kant at work on immediate ancestors of central ideas in the first Critique and might therefore be expected to shed light on an important chapter in Kant's philosophical development.
