Given (1) Wittgensteins externalist analysis of the distinction between following a rule and behaving in accordance with a rule, (2) prima facie connections between rule-following and psychological capacities, and (3) pragmatic issues about training, it follows that most, even all, future artificially intelligent computers and robots will not use language, possess concepts, or reason. This argument suggests that AIs traditional aim of building machines with minds, exemplified in current work on cognitive robotics, is in need of substantial revision.

In this paper I will examine the embodied dimension of emotions, and of inner life more generally, according to Wittgenstein’s anti-subjectivistic account of expression. First of all, I will explore Wittgenstein’s critique of a Cartesian disembodied account of the inner life, and the related argument against the existence of a private language. Secondly, I will describe the constitution of inner life as the acquisition of embodied ways of expressing oneself and of responding to others within a shared context, against the (...) background of an inherited weave of cultural expressive practices. Here, I will analyze Wittgenstein’s embodied account of expression, the ‘modified concept of sensing’ and ‘seeing’ which is involved in seeing the emotions of others as their expressions, and consequently Wittgenstein’s critique of an epistemological account concerning our ‘knowledge’ of others’ minds. Finally, with reference to Cavell’s and Mulhall’s readings, I will reflect on the figure of the ‘aspect-blind’, one who ‘just knows’ the emotion of others but cannot acknowledge it, and accordingly is not able to see it as the embodied expression of the other’s inner life. In this way, I wish to argue that Wittgenstein not only calls into question a disembodied account of the inner life from a theoretical point of view, but also shows the ethical consequences of a disembodied account of self through the figure of the aspect-blind.

The paper first gives a conceptual distinction of the first, second and third person perspectives in social cognition research and connects them to the major present theories of understanding others (simulation, interaction and theory theory). It then argues for a foundational role of second person interactions for the development of social perspectives. To support this thesis, the paper analyzes in detail how infants, in particular through triangular interactions with persons and objects, expand their understanding of perspectives and arrive at a (...) self–other metaperspective. This allows them to grasp the other’s as well as their own perspective as such, which is equivalent to an explicit third person perspective and to an explicit first person perspective or self-consciousness. The paper describes the major steps towards these perspectives, pointing to a close interdependence of both developments. It argues that embodied second person interactions are not only an enabling, but the constitutive condition for the development of an explicit first and third person perspective. (shrink)

Strong pluralists hold that not even permanent material coincidence is enough for identity. Strong pluralism entails the possibility of purely material objects -- even if not coincident -- alike in all general respects, categorial and dispositional, relational and non-relational, past, present and future, at the microphysical level, but differing in some general modal, counterfactual or dispositional repscts at the macrophysical level. It is objectionable because it thus deprives us of the explanatory resources to explain why evident absurdities are absurd. A (...) second objection is to the suggestion that cases involving artefacts can illustrate strong pluralism. This offends against the principle that gien a complex intrinsic microphysical property instantiated in some regiion, the number of material things possessing it in that region cannot depend on the existence and nature of intentional activity taking place outside it.

Alan Turing anticipated many areas of current research incomputer and cognitive science. This article outlines his contributionsto Artificial Intelligence, connectionism, hypercomputation, andArtificial Life, and also describes Turing's pioneering role in thedevelopment of electronic stored-program digital computers. It locatesthe origins of Artificial Intelligence in postwar Britain. It examinesthe intellectual connections between the work of Turing and ofWittgenstein in respect of their views on cognition, on machineintelligence, and on the relation between provability and truth. Wecriticise widespread and influential misunderstandings of theChurch–Turing thesis (...) and of the halting theorem. We also explore theidea of hypercomputation, outlining a number of notional machines thatcompute the uncomputable. (shrink)

This is a paper about the way language meshes with life. It focuses on Ludwig Wittgenstein’s later work, and compares it with Leo Tolstoy and Saint Augustine’s confessions. My aim is to better understand in this way what it means to have meaning in language, as well as meaning in life.
