In this paper I want to propose that we see solipsism as arising from certain problems we have about identifying ourselves as subjects in an objective world. The discussion will centre on Wittgenstein.

This paper investigates a particular philosophical puzzle via an examination of its status in the writings of Wittgenstein. The puzzle concerns negation and can take on three interrelated guises. The first puzzle is how not-p can so much as negate p at all – for if p is not the case, then nothing corresponds to p. The second puzzle is how not-p can so much as negate p at all when not-p rejects p not as false but as unintelligible – (...) for if p is unintelligible, then p is nothing but scratches and sounds and does not seem apt for negation. And the third puzzle is how “not” could be anything but hopelessly equivocal if it sometimes (per the first puzzle) requires, and sometimes (per the second puzzle) precludes the intelligibility of p. The paper investigates these three puzzles, their respective structures, and their relations to each other. The second puzzle is expounded as the centre of gravity, and in countering two objections to the threefold puzzle, a special predicament is expounded with regard to the second puzzle’s concern with unipolar propositions – propositions that do not admit of an intelligible negation. The text concludes by indicating the first steps that could potentially lead us out of the threefold puzzle. (shrink)

Sophocles' Antigone contains the first recorded instance of the word αὑτ ό νομος, the source for our word “autonomous”. I argue that reflection upon the human aspiration toward autonomy is central to that work. I begin by focusing on the difficulty readers of the play have determining whether Antigone's actions in the play should be considered autonomous and then suggest that recognizing this difficulty is crucial to a proper understanding of the play. The very aspects of Antigone's character that seem (...) to militate against understanding her actions within the play as autonomous—her rejection of life, her intimacy with death and the way she seems defined by her incestuous heritage— serve to illustrate the inherently problematic character of a moral ideal that we can provisionally call Antigone's autonomy. I show how the movement of the play can be understood in terms of Antigone's progress from what Kant would characterize as a heteronomous representation of her irremissible duty to bury her dead brother, to a self-conception defined by a recognition and embrace of her autonomy understood as, in Kant's words, “a respect for something entirely different from life”. Antigone's autonomy is exemplified by her choice to be dead, the choice to bear the burden of responsibility to her own. This choice, I argue, must be understood as the choice of herself as defined by her obligation to her own. Sophocles' Antigone suggests that the moral ideal Antigone represents is unliveable, but that this ideal is nonetheless essential to human moral aspiration. (shrink)

A distinction is made between imagination in the narrow sense and in the broad sense. Narrow imagination is characterised as the ability to "see" pictures in the mind's eye or to "hear" melodies in the head. Broad imagination is taken to be the faculty of creating, either in the strict sense of making something ex nihilo or in the looser sense of seeing patterns in some data. The article focuses on a particular sort of broad imagination, the kind that has (...) to do with creating, not a work of art, a scientific theory or a political vision but one's own life. We shape our lives through our actions, and these actions not only influence our future—a commonplace—but also determine our past, which is a new and more controversial perspective. (shrink)

The emperor's new mind (hereafter Emperor) is an attempt to put forward a scientific alternative to the viewpoint of according to which mental activity is merely the acting out of some algorithmic procedure. John Searle and other thinkers have likewise argued that mere calculation does not, of itself, evoke conscious mental attributes, such as understanding or intentionality, but they are still prepared to accept the action the brain, like that of any other physical object, could in principle be simulated by (...) a computer. In Emperor I go further than this and suggest that the outward manifestations ofconscious mental activity cannot even be properly simulated by calculation. To support this view, I use various arguments to show that the results of mathematical insight, in particular, do not seem to be obtained algorithmically. The main thrust ofthis work, however, is to present an overview ofthe present state of physical understanding and to show that an important gap exists at the point where, quantum and classical physics meet, as well as to speculate on how the conscious brain might be taking advantage ofwhatever new physics is needed to fill this gap to achieve its nonalgorithmic effects.

This article traces the historical origins of the modern concept of a private inner self., with precursors in Plato and Plotinus, its first full appearance in Augustine, its classic modern form in Locke, and its dissolution in postmodernism. The article elaborates the historical narrative given in my Augustine's Invention of the Inner Self (Oxford University Press, 2000).

In 'A Theory of Human Action' (1970) Alvin Goldman launched an attack on what has become known as the Anscombe-Davidson Identity Thesis. In brief, this is the thesis that our acts are our body movements, and that all the different effects of that movement do not entail that different acts have been performed, but only that an identical act has different descriptions. In her response to Goldman, Anscombe (1981) claims that Goldman is arguing at cross-purposes. I will argue that this (...) is partially true, but only because she accepts what I shall call the Symmetry Thesis. This thesis in turn is natural if you accept a third thesis called the Irreducibility Thesis. These three theses form a consistent set that the defenders of the Identity Thesis would accept and its detractors would deny. It follows that the best way to attack the Identity Thesis is to attack the Irreducibility Thesis on which it is based. I believe that this can be done and that Goldman is basically right, but I will not be concerned with a full defense of Goldman's method of individuating actions against its competitors. Rather, I want to show the grounds, some of them extralogical, upon which preference can be made. (shrink)

Explanations of how psychological capacities are carried out often invoke functional brain areas. I argue that such explanations cannot succeed. Psychological capacities are carried out by identifiable entities and their activities in the brain, but functional brain areas are not the relevant entities. I proceed by assuming that if functional brain areas did carry out psychological capacities, then these brain areas could be included in descriptions of mechanisms. And if functional brain areas participate in mechanisms, then they must engage in (...) activities. A number of ways in which we might understand the claim that functional brain areas engage in activities are examined. None are successful, and so one conclusion is that functional brain areas do not participate in mechanisms. Consequently, they are not the entities that carry out psychological capacities. (shrink)
