Like everyone with a scientific bent of mind, Dennett thinks our capacity for meaningful language and states of mind is the product of evolution (Dennett [1987, ch. VIII]). But unlike many of this bent, he sees virtue in viewing evolution itself from the intentional stance. From this stance, ?Mother Nature?, or the process of evolution by natural selection, bestows intentionality upon us, hence we are not Unmeant Meaners. Thus, our intentionality is extrinsic, and Dennett dismisses the theories of meaning of (...) Dretske, Fodor, Burge, Putnam, and Kripke on the grounds that each requires that our mental states, unlike those of artifacts, have meaning intrinsically. I argue that we are Unmeant Meaners, incidentally defending Dretske et al., though my goal is to test the explanatory virtue of the intentional stance as applied to the evolution of intentionality.

This essay examines one of the cornerstones of Leibniz's defense of teleology within the order of nature. The first section explores Leibniz's contributions to the study of geometrical optics, and argues that his "Most Determined Path Principle" or "MDPP" allows him to bring to the fore philosophical issues concerning the legitimacy of teleological explanations by addressing two technical objections raised by Cartesians to non-mechanistic derivations of the laws of optics. The second section argues that, by drawing on laws such as (...) the MDPP, Leibniz is able to introduce a thin notion of teleology that gives him the resources to respond to the most pressing charges of his day against teleological explanations within natural philosophy. Finally, the third section argues that contemporary philosophers have been overly hasty in their dismissal of Leibniz's account of natural teleology, and indeed that their own generally thin conceptions of teleology have left them with few well-motivated resources for resisting his elegant position.

In these notes, unadorned page numbers under 350 refer to Dennett (1987) - The Intentional Stance, hereafter referred to as Stance - and ones over 495 refer to Dennett (1988) - mostly to material by him but occasionally to remarks of his critics. Since the notes will focus on disagreements, I should say now that I am in Dennett’s camp and am deeply in debt to his work in the philosophy of mind, which I think is wider, deeper, more various (...) and more fruitful than mine or anyone else’s. Still, I have some ideas and emphases that I think he could profit from. In the final chapter of Stance Dennett compares his work with that of several others, including me. He sees me as having a position like his, the main difference being that I think (as he doesn’t) that our attributions of mental content can always be highly determinate (pp. 347f). In fact, there are differences between us but this isn’t one of them. I want to get this straight, so as to clear the decks for the positive points I am going to make. There is some indeterminacy and there could be lots of it; Dennett’s case for that is unanswerable. As for how much there actually is: I don’t know and don’t even suspect; there is simply no declared issue between Dennett and myself on that. Nor do we disagree on a related matter. If there is no evidence that settles whether the animal believes that P or believes that Q, should we say that nevertheless one of these is right, and it’s just that we can’t know which it is? Dennett says No. I perfectly agree. (shrink)

This paper criticizes the account of desire defended by Nomy Arpaly and Timothy Schroeder in their recent book, In Praise of Desire. It contrasts their account with one that I favor, a cluster analysis listing various criteria that are together sufficient for having paradigm desires, but none of which is necessary or sufficient for desiring. I argue that their account fails to state necessary or sufficient conditions, that it is explanatorily weaker than the cluster account, that it fails to provide (...) a neat reduction of desires to neurophysical terms, and that in any case such a reduction is not required for the preservation of the concept of desire in mature psychology. Implications are drawn for the broader debate between reductionists, eliminativists, and defenders of folk psychological concepts. (shrink)

This paper investigates whether, or not, the behavior of animals without speech can manifest beliefs and desires. Criteria for the attribution of such beliefs and desires are worked out with reference to Jonathan Bennett's theory of cognitive teleology: A particular ability for learning justifies attributing such beliefs and desires. The conceptual analysis is illustrated by examinations of cognitive ethology and considers higher-order intentionality. It is argued that the behavioral evidence only supports the attribution of first order beliefs and that languageless (...) animals therefore could not possess higher-order intentionality. They are only capable of forming simple, i.e., first-order beliefs about their environment. (shrink)

No philosopher has worked harder than Dan Dennett to set the possibility of machine mentality on firm philosophical footing. Dennett’s defense of this possibility has both a positive and a negative thrust. On the positive side, he has developed an account of mental activity that is tailor-made for the attribution of intentional states to purely mechanical contrivances, while on the negative side, he pillories as mystery mongering and skyhook grasping any attempts to erect barriers to the conception of machine mentality (...) by excavating gulfs to keep us “bona fide” thinkers apart from the rest of creation. While I think he’s “won” the rhetorical tilts with his philosophical adversaries, I worry that Dennett’s negative side sometimes gets the better of him, and that this obscures advances that can be made on the positive side of his program. In this paper, I show that Dennett is much too dismissive of original intentionality in particular, and that this notion can be put to good theoretical use after all. Though deployed to distinguish different grades of mentality, it can (and should) be incorporated into a philosophical account of the mind that is recognizably Dennettian in spirit. (shrink)

Yawning has a well documented contagious effect: viewing or hearing a yawn—as well as talking or thinking about yawns—causes human subjects to yawn. While comparative ethological and neurological accounts suggest that yawning is a function of primitive biological structures in the brain stem, these analyses do not account for infectious yawning caused by representational and semantic states. Investigating the relationship between perceptual and cognitive avenues of yawn induction affords a unique opportunity to examine how higher level cognitive faculties interact with (...) involuntary or automated processing systems. In this paper, I examine three distinct attempts to reconcile the cognitive properties of contagious yawning with its physiological basis—one neurological, one philosophical, and one functional. None of these accounts are unproblematic, and the most plausible hypothesis for the evolution of contagious yawning does not satisfactorily explain the cognitive iterations of the phenomenon . I argue that the most likely explanation of the contagion links perceptual elements of witnessed yawns to conceptual representations. More centrally, this kind of integrated account has repercussions for general theories of human thought and rationality, and suggests that higher level representational states engage neurophysiological structures in determining human behavior.
