In On the Content and Object of Presentations, Kasimir Twardowski presents an interesting line of thought concerning the content of a presentation and its relation to the object of that presentation. This way of thinking about content is valuable for understanding phenomenal intentionality, and it should also be important for the project of “naturalizing” the mental (or at least for discovering the neural correlates of the phenomenal). According to this view, content is that by virtue of which a presentation of (...) an object presents a certain object and no other. In the cases in which an object is presented as simple, there is nothing more that can be said about the relation of content and object. It is sui generis: the relation of content to an object by virtue of which it presents that object. Further, the content of a presentation is never itself directly presented. The content can only be gotten at indirectly, as the content by which such and such object is presented. Where the presented object is complex—as is of course the normal case—a lot that is useful can be said about the structure of the content. In this paper, I lay out Twardowski's theory of the content of presentations. Since the business of content is to present its object, I briefly present the basics of Twardowski's mereology of objects. (shrink)

Common names, for Mill, have both connotation and denotation. Thus ‘horse’ connotes certain properties, and the name ‘horse’ denotes the things that have those properties. By contrast, proper names have no connotations; they do not denote in virtue of the possession of certain properties by their denotations, but so to speak, directly. Thus Socrates received his name by being dubbed ‘Socrates’; and he might just as well have been given any other name. This contrast is misleading. After all, we might (...) have named horses by another name, too; e.g., ‘cow’ or ‘Pferd’. However, once the convention by which they are called ‘horses’ is established, it is not correct to call them ‘cows’. A horse is not a cow. Just so Socrates could have been named ‘Plato’ or ‘Moses’, but once he has been named ‘Socrates’, it is just as wrong to call him ‘Plato’ as it is to call a horse a ‘cow’. What is correctly called a ‘horse’ is so called in virtue of its possession of certain properties, just as what is called ‘Socrates’ is so called in virtue of his possession of the requisite properties. From this point of view, proper names are words like any others. (Leonard Linsky, Oblique Contexts, University of Chicago Press 1983, pp. 16f.). (shrink)

We have a familiar idea of levels of description or levels of theory in science: microphysics, atomic physics, chemistry, biology, psychology, and the various social sciences. It is clear that philosophers - such as Terry Horgan - who want to be nonreductive materialists with regard to the mental must hold that this is not mere description; there must be genuine higher-level causes, and hence, genuine higher-level properties, in particular mental properties and causes. But there appears to be a deep problem (...) concerning mental causes. The (micro-) physical world is causally closed. Mental states are - or depend on or are realized by - physical states. It seems, then, that the physical state on which a mental state depends will be responsible for any alleged effects of the mental state. There will be no room for mental causation. And if properties exist insofar at they have a causal role, there will be no room for mental properties either. Many philosophers - Horgan included - have seen this problem of the "causalexclusion" ofthe mental as a specialcase of a general problem:the exclusion of higher-level causes by the causal closure of microphysics. Suppose one higher-level state, H1 leads to another higher-level state, H2. H1 is realized by some base level state, B1, which leads to a base-level state, B2, which in turn realizes H2. All of the casual work, so to speak, takes place at the base level. There is no room for any genuine causal connection between H1, as such, and H2, as such. I argue that there is no problem about higher-order causation in general. There are genuine, unsurprising higher-level causes and properties. A ball roles, for example, or breaks a window. If there is a problem of exclusion regarding putative mental causes, it is not an instance of a general exclusion problem, but is sui generis, and mental causation remains mysterious. (shrink)

Andy Clark argues that the reality and causal efficacy of the folk psychological attitudes do not require in‐the‐head correlates of the that‐clauses by which they are attributed. The facts for which Fodor invokes a language of thought as empirical explanation—systemati‐city, for example—are, Clark argues, an a priori conceptual demand upon propositional attitude ascription, and hence not in need of empirical explanation. However, no such strategy can work. A priori demands imposed by our practices do not eliminate the need for empirical (...) explanation of how these demands are satisfied by particular beings. And given the vast number of potential beliefs, and the interrelationships they exhibit, no one has the slightest idea how they might be explained except by in‐the‐head syntax. (shrink)

Any successful account of general terms must explain our ability to apply terms correctly to new instances. Many philosophers have thought resemblance offers an ontologically sparse basis for such an account. However, Any natural and plausible account of general terms on the basis of resemblance requires quite a rich ontology, Including at least second order properties and relations. Given a sufficiently rich structure of resemblances, We can surely account for the application of many general terms. I argue, However, That our (...) ability to recognize shapes and to apply terms for shapes cannot be explained on the basis of resemblance. (shrink)

Hardcastle argues that we make distinctions where there are no differences when we speak of (1) levels of description, (2) cognitive forces, and (3) soft laws in psychology. Concerning (1) and (2), the differences just are differences in description. The same state is referred to by three different descriptions, and talk of cognitive forces is appropriate and useful at the cognitive level of description. And concerning (3), if our view of cognition is correct, then the laws of psychology are importantly (...) different in form from those of physics. (shrink)

In Connectionism and the Philosophy of Psychology, Horgan and Tienson articulate and defend a new view of cognition.

Consciousness and intentionality help to define the mental qua mental. Consciousness and intentionality, insist some philosophers, although perhaps often co‐occurring, are mutually independent or separable. Consciousness and intentionality, insist others, are interdependent or inseparable. This chapter discusses an important aspect of inseparatism: the relation between phenomenal character and intentional content. The contemporary philosophers and theorists have developed inseparatist or nearly inseparatist theses in various ways. The chapter mentions some of this work, and the philosophers responsible for it. It discusses two (...) implications of thesis C‐Ins. First, since phenomenally conscious states are mental, every phenomenally conscious state also is intentional. Second, since phenomenally intentional content is determined by phenomenal character alone, such content is entirely constituted by features internal or intrinsic to phenomenology. Finally, the chapter sketches the questions about or challenges to inseparatism and explains something, again briefly, about how the inseparatist might reply to each. (shrink)

In the first post World War II identity theories (e.g., Place 1956, Smart 1962), mind brain identities were held to be contingent. However, in work beginning in the late 1960's, Saul Kripke (1971, 1980) convinced the philosophical community that true identity statements involving names and natural kind terms are necessarily true and furthermore, that many such necessary identities can only be known a posteriori. Kripke also offered an explanation of the a posteriori nature of ordinary theoretical identities such as that (...) water = H2O. We identify the kinds and substances involved in theoretical identities by certain of their contingent properties. What we discover when we discover a theoretical identity is the underlying nature of the kind that we identify by those contingent properties. Now, of course, it was being a posteriori, not being contingent, that mattered to the identity theorists anyway, so the necessity of identity is not, in itself, damaging to mind brain identity theories. However, Kripke also argued persuasively that the alleged mind brain identities could not be treated in the same way as ordinary theoretical identities. We "identify" pain by feeling it, and surely how it feels is an essential property of pain, not a contingent property. Thus, a mind body identity theory must provide a different explanation of why its identities are a posteriori. A new wave of materialists has appeared on the scene with a new strategy for explaining [1] the a posteriori nature of its alleged identities. The strategy is to locate the explanation for the a posteriori nature of mind body identities, not on the side of the world, but on the side of the mind -in different ways of thinking about or imagining, or in different concepts. Thus, on this new view, there is only one property—this brain process type, which is identical with this pain.. (shrink)

David Marr provided a useful framework for theorizing about cognition within classical, AI-style cognitive science, in terms of three levels of description: the levels of (i) cognitive function, (ii) algorithm and (iii) physical implementation. We generalize this framework: (i) cognitive state transitions, (ii) mathematical/functional design and (iii) physical implementation or realization. Specifying the middle, design level to be the theory of dynamical systems yields a nonclassical, alternative framework that suits (but is not committed to) connectionism. We consider how a brain's (...) (or a network's) being a dynamical system might be the key both to its realizing various essential features of cognition — productivity, systematicity, structure-sensitive processing, syntax — and also to a non-classical solution of (frame-type) problems plaguing classical cognitive science.
