How do we form concepts like those of three, bicycle and red? According to Kant, we form them by carrying out acts of comparison, reflection and abstraction on information provided by the senses. Kant's answer raised numerous objections from philosophers and psychologists alike. "Kant e la formazione dei concetti" argues that Kant is able to rebut those objections. The book shows that, for Kant, it is possible to perceive objects without employing concepts; it explains how, given those perceptions, we can (...) form categories and empirical concepts; and it argues that theories like Kant's - abstractionist theories of concept formation - are more plausible than is often assumed.

Shepherd’s argument against Hume’s thesis that an object can begin its existence uncaused has received short shrift in the secondary literature. I argue that the key to understanding that argument’s success is understanding its dialectical context. Shepherd sees the dialectical situation as follows. Hume presents an argument against Locke and Clarke the conclusion of which is that an object can come into existence uncaused. An essential premise of that argument is Hume’s theory of mental representation. Hume’s theory of mental representation, (...) however, is itself implausible and unsupported. Therefore, one need not accept this premise or this conclusion. Thus, Shepherd proceeds to her discussion of the relation of cause and effect free to help herself to the thesis that every beginning of existence must have a cause. Additionally, she elsewhere pays down the debt she incurs in that argument by presenting her own alternative theory of mental representation, which is both plausible in its own right, and can account for the error that she takes Hume to make.

Kant’s argument in the First Analogy for the permanence of substance has been cast as consisting of a simple quantifierscope mistake. Kant is portrayed as illicitly moving from a premise such as (1) at all times, there must exist some substance, to a conclusion such as (2) some particular substance must exist at all times. Examples meant to show that Kant makes this mistake feature substances coming into and out of existence, but doing so at overlapping times. I argue that (...) Kant offers an argument against this kind of example in the following passage. Kant’s claim is that, were substances to be created and destroyed as in the example, the appearances would then be related to two different times, in which existence flowed side by side, which is absurd. For there is only one time, in which all different times must not be placed simultaneously but only one after another (A188–9/B231–32). (shrink)

In a recent paper, Robert Hanna argues that Kant's incongruent counterparts example can be mobilized to show that some mental representations, which represent complex states of affairs as complex, do so entirely non-conceptually. I will argue that Hanna is right to see that Kant uses incongruent counterparts to show that there must be a non-conceptual component to cognition, but goes too far in concluding that there must be entirely non-conceptual representations that represent objects as existing in space and time. Kant (...) is deeply committed to the thesis that no representation of a complex state of affairs as complex can be entirely non-conceptual. For Kant, all representations of complex states of affairs as complex (including those of incongruent counterparts) are conceptually structured. I present an interpretation of the Transcendental Aesthetic according to which Kant not only aims at Leibnizian and Newtonian accounts of space and time, but also Hume's. Hume's account fails to make representations of complex states of affairs sufficiently determinate. Kant offers an account later in the Critique that is meant to correct this failing by requiring that all representations of complex states of affairs as complex be conceptually (inferentially) structured.

In a recent paper, Karl Schafer argues that Hume's theory of mental representation has two distinct components, unified by their shared feature of having accuracy conditions. As Schafer sees it, simple and complex ideas represent the intrinsic imagistic features of their objects whereas abstract ideas represent the relations or structures in which multiple objects stand. This distinction, however, is untenable for at least two related reasons. Firstly, complex ideas represent the relations or structures in which the impressions that are the (...) objects of their simple components stand. Secondly, abstract ideas are themselves instances of complex ideas. I draw two important conclusions from these facts. Firstly, contra Schafer and Garrett, the Copy Principle, properly emended, constitutes the entirety of Hume's theory of mental representation. Secondly, whereas paradigm examples of complex ideas, e.g. ideas of spatial and temporal complexes, are structured by relations of contiguity, abstract ideas are those complex ideas instead structured by relations of resemblance. As such, they represent their objects not as spatially or temporally contiguous but rather as resembling. (shrink)

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.

Margaret Kohn argues for a reappraisal of early twentieth-century left-republican French political theory, known as ‘solidarism’. Solidarism recognises private property as legitimate, but at the same time argues that the collective nature of economic production gives rise to a claim to social property. It is social property that should underlie the case for social justice and social rights, not the standard liberal claims to individual autonomy. This paper provides an appraisal of Kohn’s recovery of solidarism, taking as its main theme (...) the relation between property and social justice. The paper first offers a typology of four theories of justice (right- and left-libertarianism, luck and relational egalitarianism) and discusses the relation of each of these to the concept of property. Then it argues that solidarism is akin to left-libertarianism in the way it formulates justice as a claim to social property. Finally, it argues that solidarists cannot escape grounding their theory in a non-property based fundamental principle, which makes the theory much less distinctive from egalitarian theories of justice than may appear at first sight.
