A few philosophers of biology have recently explicitly rejected Essential Membership, the doctrine that if an individual organism belongs to a taxon, particularly a species, it does so essentially. But philosophers of biology have not addressed the broader issue, much discussed by metaphysicians on the basis of modal intuitions, of what is essential to the organism. In this paper, I address that issue from a biological basis, arguing for the Kripkean view that an organism has a partly intrinsic, partly historical, (...) essence. The arguments appeal to the demands of biological explanation and are analogous to arguments that I have given elsewhere that a taxon has a partly intrinsic, partly historical, essence. These conclusions about the essences of individuals and taxa yield an argument for Essential Membership. Finally, I cast doubt on LaPorte’s objection to that doctrine arising from the view that a species cannot survive having a daughter. (shrink)

Reductive, naturalistic psychosemantic theories do not have a good track record when it comes to accommodating the representation of kinds. In this paper, I will suggest a particular teleosemantic strategy to solve this problem, grounded in the neurocomputational details of the cerebral cortex. It is a strategy with some parallels to one that Ruth Millikan has suggested, but to which insufficient attention has been paid. This lack of attention is perhaps due to a lack of appreciation for the severity of (...) the problem, so I begin by explaining why the situation is indeed a dire one. One of the main tasks for a naturalistic psychosemantic theory is to describe how the extensions of mental representations are determined. (Such a theory may also attempt to account for other aspects of the “meaning” of mental representations, if there are any.) Some mental representations, e.g. the concept of water, denote kinds (I shall be assuming this is non-negotiable). How is this possible? Unfortunately, I haven’t the space to canvass all the theories out there and show that each one fails to accommodate the representation of kinds, but I will point out the major types of problems that arise for the kinds of theories that, judging by the literature, are considered viable contenders.1 In general, the theories either attempt and fail to account for the representation of kinds, or they fall back on something like an intention to refer to a kind – not exactly the most auspicious move for a reductive theory. There are a number of problems that prevent non-teleosemantic theories from explaining how it is possible to represent kinds. A concept of a kind K must.. (shrink)

Part 1 of the thesis questions the traditional relation model of intentionality. After fixing reference on the target phenomenon, intentionality, and explaining my interest in it, I ask what sorts of things intentionality might be a relation to. I consider ordinary objects, properties, propositions and hybrid views, and conclude all make the intentional relation appear rather mysterious. From there, I move on to examine the relation view’s most prominent proponents, the tracking theorists—pointing out some challenges such views face, and concluding (...) that it might be worthwhile looking into alternatives to the relation view. Part 2 asks whether the newly emerging phenomenal intentionality movement can provide a viable alternative to the relation model of intentionality. After focusing on a specific kind of phenomenal intentionality theory—something I call modificationism—I examine three such accounts. From there I go on to discuss some common complaints/challenges these kinds of views face, and consider how they might be addressed within the modificationist framework. In Part 3, I address what I call the problem of cognitive contact: how do our contentful mental states manage to make cognitive contact with the ordinary objects (e.g. tables and chairs) that they appear to. The problem is particularly acute for any version of phenomenal intentionality that denies the relation view, and has been given very little attention in the literature. I consider how a modificationist might address this problem, and conclude that though some avenues appear promising, there is nevertheless a great deal of work to be done if modificationism, and phenomenal intentionality theory, is to overcome this problem.

What makes a mental representation about what it's about? The majority view among naturalists seems to be that representation has something to do with causation, or information, or correlation, or some other related notion. But such "information-based" views (e.g. Fodor, Prinz, Stalnaker, Usher, Mandik, Tye, and lots of other people who gesture towards this kind of theory1) cannot accommodate representation of the distal.

Most people find it obvious that concepts like APPLE, DOG, WATER, CACTUS, SWIM, CHIRP, FURRY, and SMOOTH are acquired from perceptual experiences along with some kind of inferential procedure. Models of how these concepts are inferentially acquired, however, force the acquired concepts to be representationally complex, built from, and composed by, the more primitive representations. Since at least the time of Plato, philosophers and psychologists have struggled to find complex sets of representations that have the same meanings, definitionally or probabilistically, (...) as these concepts. For example, to think about the property-kind being gold is not the same as to think about the complex property-kind being yellowish & shiny & malleable.... I call this Fodor's Challenge: Find an acquisition process that is genuinely inferential and yields a concept that genuinely is one of these lexical concepts. Rather than continue the pursuit of a complex representation that has the same meaning as our concept GOLD. I offer a model on which many lexical concepts are acquired from perception and inference, without being built up from, and composed by, the representations involved. The model, Baptizing Meanings for Concepts, is inspired in part by Saul Kripke's baptism process for assigning meanings to linguistic terms. Many lexical concepts, according to the BMC, are acquired by inferring the presence a new property-kind, picking out the property-kind in terms of those perceptible features, and then assigning a simple mental term, a concept, for that property-kind.

The aim of this dissertation is to create a naturalistic philosophical picture of creative capacities that are specific to our species, focusing on artistic ability, religious reflection, and scientific study. By integrating data from diverse domains within a philosophical anthropological framework, I have presented a cognitive and evolutionary approach to the question of why humans, but not other animals engage in such activities. Through an application of cognitive and evolutionary perspectives to the study of these behaviors, I have sought to (...) provide a more solid footing for philosophical anthropological discussions of uniquely human behavior. In particular, I have argued that art, religion and science, which are usually seen as achievements that are quite remote from ordinary modes of reasoning, are subserved by evolved cognitive processes that serve functions in everyday cognitive tasks, that arise early and spontaneously in cognitive development, that are shared cross-culturally, and that have evolved in response to selective pressures in our ancestral past. These mundane cognitive processes provide a measuring rod with which we can assess a diversity of cultural phenomena; they form a unified explanatory framework to approach human culture. I have argued that we can explain uncommon thoughts in terms of interactions between common minds. This dissertation is subdivided into four parts. Part I outlines the problem of human uniqueness, examining theories on how humans conceptualize the world, and what their mental tool box looks like. Part II discusses the evolutionary and cognitive origins of human artistic behavior. Part III focuses on the cognitive science of religion, especially on how it can be applied to the reasoning of theologians and philosophers of religion. Part IV considers the cognitive basis of scientific practice. (shrink)

In Italian schools Philosophy is taught as History of Philosophy in the last three years of some courses of secondary schools. The aim of my research is to show that teaching Philosophy through some basic words can be a good approach to teach this subject at school. The words that are interesting for this approach are those that we use on a daily basis and do not consider problematic. Philosophy gives useful contents and methods in order to call into question (...) concepts that we give for granted or we often use without a critical approach. My research is divided in two parts. In the first part I illustrate the history of Philosophy teaching in Italian education with relation to the philosophical debate in our Country. In the second part I present the ‘teaching Philosophy through words’ approach and discuss its assumptions and theoretical implications. In this part I show that a concept’s analysis is not separable from historical perspective. At the end of my research, the ‘teaching philosophy through words’ approach shows to be a good approach to teach Philosophy beyond or beside the historical method. In fact, the ‘teaching Philosophy through words’ approach leads to the acquisition of conceptual competence, together with an historical comprehension of the philosophical debate. (shrink)

This article provides a critical overview of competing theories of conceptual structure (definitional structure, probabilistic structure, theory structure), including the view that concepts have no structure (atomism). We argue that the explanatory demands that these different theories answer to are best accommodated by an organization in which concepts are taken to have atomic cores that are linked to differing types of conceptual structure.

Many students of pragmatics and child language have come to believe that in order to learn a language a child must first have a 'theory of mind,' a grasp that speakers mentally represent the content they would convey when they speak. This view is reinforced by the Gricean theory of communication, according to which speakers intend their words to cause hearers to believe or to do certain things and hearers must recognize these intentions if they are to comply. The view (...) rests on an underlying assumption that learning language involves associating words with things (objects, kinds, events, properties and so forth) or with concepts of these, these associations being acquired, one by one, by observing the usage of others. Accomplishing this task is facilitated, it is thought, by engaging in joint attention with speakers who are attending to the things they are talking about as they talk, and joint attention requires an understanding that others have minds that represent things.
