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.

Abstract Both parties in the active philosophical debate concerning the conceptual character of perception trace their roots back to Kant's account of sensible intuition in the Critique of Pure Reason. This striking fact can be attributed to Kant's tendency both to assert and to deny the involvement of our conceptual capacities in sensible intuition. He appears to waver between these two positions in different passages, and can thus seem thoroughly confused on this issue. But this is not, in fact, the (...) case, for, as I will argue, the appearance of contradiction in his account stems from the failure of some commentators to pay sufficient attention to Kant's developmental approach to philosophy. Although he begins by asserting the independence of intuition, Kant proceeds from this nonconceptualist starting point to reveal a deeper connection between intuitions and concepts. On this reading, Kant's seemingly conflicting claims are actually the result of a careful and deliberate strategy for gradually convincing his readers of the conceptual nature of perception.

In a well-known passage from the Introduction to Kant’s Critique of Judgment, Kant defines the power or faculty of judgment [Urteilskraft] as "the capacity to think the particular as contained under the universal" (Introduction IV, 5:179).1 He then distinguishes two ways in which this faculty can be exercised, namely as determining or as reflecting. These two ways are defined as follows: "If the universal (the rule, the principle, the law) is given, then judgment, which subsumes the particular under it... is (...) determining. But if merely the particular is given, for which the universal is to be found, then judgment is merely reflecting" (ibid.) As Kant goes on to make clear, the Critique of Judgment is particularly concerned with judgment in its capacity as reflecting rather than determining. It is concerned, that is, with how we are to find universals (which he glosses as rules, principles, or laws) for given particulars. Despite the fact that the term "concept" does not appear in this set of definitions, Kant’s discussions of judgment elsewhere make it clear that this faculty can be identified at least in part with our capacity to think particular objects under concepts, in particular empirical concepts.2 The..

Robert Hanna presents a fresh view of the Kantian and analytic traditions that have dominated continental European and Anglo-American philosophy over the last two centuries, and of the connections between them. But this is not just a study in the history of philosophy, for out of this emerges Hanna's original approach to two much-contested theories that remain at the heart of contemporary philosophy. Hanna puts forward a new 'cognitive-semantic' interpretation of transcendental idealism, and a vigorous defense of Kant's theory of (...) analytic and synthetic necessary truth, making this compelling reading for all who are interested in these fundamental philosophical issues.

Contemporary debates in epistemology devote much attention to the nature of knowledge, but neglect the question of its sources. This book focuses on the latter, especially on the question of innateness. Carruthers' aim is to transform and reinvigorate contemporary empiricism, while also providing an introduction to a range of issues in the theory of knowledge. He gives a lively presentation and assessment of the claims of classical empiricism, particularly its denial of substantive a priori knowledge and of innate knowledge. He (...) argues that we would be right to reject the substantive a priori but not innateness, and then presents a novel account of the main motivation behind empiricism, which leaves contemporary empiricists free to accept innate knowledge and concepts. Carruthers closes with a discussion of scepticism, arguing that acceptance of innate concepts may lead to a decisive resolution of the problem in favor of realism. (shrink)

Our understanding of the sense of taste is largely based on research designed and interpreted in terms of the traditional four tastes: sweet, sour, salty, and bitter, and now a few more. This concept of basic tastes has no rational definition to test, and thus it has not been tested. As a demonstration, a preliminary attempt to test one common but arbitrary psychophysical definition of basic tastes is included in this article; that the basic tastes are unique in being able (...) to account for other tastes. This definition was falsified in that other stimuli do about as well as the basic words and stimuli. To the extent that this finding might show analogies with other studies of receptor, neural, and psychophysical phenomena, the validity of the century-long literature of the science of taste based on a few is called into question. The possible origins, meaning, and influence of this concept are discussed. Tests of the model with control studies are suggested in all areas of taste related to basic tastes. As a stronger alternative to the basic tradition, the advantages of the across-fiber pattern model are discussed; it is based on a rational data-based hypothesis, and has survived attempts at falsification. Such has found broad acceptance in many neural systems. (shrink)

ACT, CONTENT, AND OBJECT THE TITLE I have chosen for this work is a mere label for a set of problems; the controversial views that have historically been ...

Considering the large extent to which Kant deals with other metaphysical topics such as substances, causes, forces, and the like, he says surprisingly little about universals. By "universals," I am referring to the contemporary conception of universals, according to which...

At least since Locke, philosophers and psychologists have usually held that concepts arise out of sensory perceptions, thoughts are built from concepts, and language enables speakers to convey their thoughts to hearers. Christopher Gauker holds that this tradition is mistaken about both concepts and language. The mind cannot abstract the building blocks of thoughts from perceptual representations. More generally, we have no account of the origin of concepts that grants them the requisite independence from language. Gauker's alternative is to show (...) that much of cognition consists in thinking by means of mental imagery, without the help of concepts, and that language is a tool by which interlocutors coordinate their actions in pursuit of shared goals. Imagistic cognition supports the acquisition and use of this tool, and when the use of this tool is internalized, it becomes the very medium of conceptual thought. (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.

In this innovative study Patricia Kitcher argues that we can only understand the deduction of the categories in Kant's Critique of Pure Reason in terms of his attempt to fathom the psychological prerequisites of thought. Thus a consideration of his conception of psychology is essential to an understanding of his philosophy. Kitcher specifically considers Kant's claims about the unity of the thinking self; the spatial forms of human perceptions; the relations among mental states necessary for them to have content; the (...) relations between perceptions and judgment; and the limits of philosophical insight into psychological processes.

A discussion of Kant's aesthetics and their place in the philosopher's theory offers a new interpretation of Kant's writings on the nature of the beautiful.

2. Invariant Sensorimotor Features ("Affordances"). To say this is not to declare oneself a Gibsonian, whatever that means. It is merely to point out that what a sensorimotor system can do is determined by what can be extracted from its motor interactions with its sensory input. If you lack sonar sensors, then your sensorimotor system cannot do what a bat's can do, at least not without the help of instruments. Light stimulation affords color vision for those of us with the (...) right sensory apparatus, but not for those of us who are color-blind. The geometric fact that, when we move, the "shadows" cast on our retina by nearby objects move faster than the shadows of further objects means that, for those of us with normal vision, our visual input affords depth perception. From more complicated facts of projective and solid geometry it follows that a 3-dimensional shape, such as, say, a boomerang, can be recognized as being the same shape Ð and the same size Ð even though the size and shape of its shadow on our retinas changes as we move in relation to it or it moves in relation to us. Its shape is said to be invariant under these sensorimotor transformations, and our visual systems can detect and extract that invariance, and translate it into a visual constancy. So we keep seeing a boomerang of the same shape and size even though the shape and size of its retinal shadows keep changing. (shrink)

In this book about metaphysics the author defends a realistic view of universals, characterizing the notion of universal by considering language and logic, the idea of possibility, hierarchies of universals, and causation. He argues that neither language nor logic is a reliable guide to the nature of reality and that basic universals are the fundamental type of universal and are central to causation. All assertions and predications about the natural world are ultimately founded on these basic universals. A distinction is (...) drawn between unified particulars and arbitrary particulars ; unified particulars are the terms of causal relations and thus the real constituents of the world. The world is not made up of events but of unified particulars and basic universals. (shrink)

Die Untersuchung wendet sich gegen die von Paulsen, Adickes, Riehl, Kemp-Smith, Strawson u.a. vertretene Ansicht, dass Kant die Gliederungspaare der Kritik der reinen Vernunft unreflektiert aus bloss systematischen Grunden aus der Logik seiner Zeit ubernommen habe. Die Analyse der Nachschriften von Kants Logikvorlesungen und der Reflexionen in seinem Logikkompendium zeigt namlich, dass Kant die beiden grossen Gliederungspaare seines Hauptwerks, transzendentale Elementar- und Methodenlehre und transzendentale Analytik und Dialektik, in seinen Vorlesungen in einem jahrzehntelangen Prozess der Auseinandersetzung mit der traditionellen Logik (...) entwickelt hat. This study opposes the view held by Paulsen, Adickes, Riehl, Kemp- Smith, Strawson etc. that Kant adopted his division into two parts in the Critique of Pure Reason without thinking and for purely systematic reasons from the logic of his time. The analysis of transcripts of Kants lectures on logic and his reflections shows that Kant developed the two major parts of his main work, transcendental doctrine of the elements and transcendental doctrine of method and transcendental analytic and dialectic, in his lectures in an analysis of traditional logic which he did over a period of many decades.

In this chapter, I outline and defend a version of concept empiricism. The theory has four central tenets: Concepts represent categories by reliable causal relations to category instances; conceptual representations of category vary from occasion to occasion; these representations are perceptually based; and these representations are all learned, not innate. The last two tenets on this list have been central to empiricism historically, and the first two have been developed in more recent years. I look at each in turn, and (...) then I discuss the most obvious objection to empiricism. According to that objection, some concepts cannot be perceptually based because they represent things that are abstract, and hence unperceivable. I discuss two standard examples: democracy and moral badness. I argue that both can be explained using resources available to the empiricist. (shrink)
