The logical problem of artificial intelligence—the question of whether the notion sometimes referred to as ‘strong’ AI is self-contradictory—is, essentially, the question of whether an artificial form of life is possible. This question has an immediately paradoxical character, which can be made explicit if we recast it (in terms that would ordinarily seem to be implied by it) as the question of whether an unnatural form of nature is possible. The present paper seeks to explain this paradoxical kind of possibility (...) by arguing that machines can share the human form of life and thus acquire human mindedness, which is to say they can be intelligent, conscious, sentient, etc. in precisely the way that a human being typically is.

An investigation of the concept of “surveyability” as traced through the thought of Hilbert, Wittgenstein, and Turing. The communicability and reproducibility of proof, with certainty, are seen as earmarked by the “surveyability” of symbols, sequences, and structures of proof in all these thinkers. Hilbert initiated the idea within his metamathematics, Wittgenstein took up a kind of game formalism in the 1920s and early 1930s in response. Turing carried Hilbert’s conception of the “surveyability” of proof in metamathematics through into his analysis (...) of what a formal system (what a step in a computation) is in “On computable numbers, with an application to the Entscheidungsproblem” (1936). Wittgenstein’s 1939 investigations of the significance of surveyability to the concept of “proof “in Principia Mathematica were influenced, both by Turing’s remarkable everyday analysis of the Hilbertian idea, and by conversations with Turing. Although Turing does not use the word “surveyability” explicitly, it is clear that the Hilbertian idea plays a recurrent role in his work, refracted through his engagement with Wittgenstein’s idea of a “language-game”. This is evinced in some of his later writings, where the “reform” of mathematical notation for the sake of human surveyability (1944/45) may be seen to draw out the Hilbertian idea. For Turing, as for Wittgenstein, the need for “surveyability” earmarks the evolving culture of humans located in an evolving social and scientific world, just as it had for Hilbert. (shrink)

In his last writings, Wittgenstein repeatedly addresses the question of how our concepts relate to general facts of nature or human nature and how they are embedded in our lives. In doing so, he uses the term “pattern of life”, characterizing the complicated relationship between concepts and our lives and how our concepts “are connected with what interests us, with what matters to us” (LWPP II, 46). But who is this “us”, and whose interests manifest in the concepts we use (...) to designate patterns of life? What if certain concepts—or their absence—are exclusionary, discriminatory, or otherwise unjust to those who are not “us”? In this paper, I want to discuss Wittgenstein’s notion of “pattern of life” in its interweaving with facts, human life, and concepts, as well as its political implications. To this end, I will first outline the relationship between facts and concept formation as Wittgenstein drew it in his last writings. Based on this, I will argue that he uses the concept of pattern of life to capture the complicated relationship between concepts and human nature or “social facts”. Going beyond Wittgenstein and drawing on recent feminist epistemology, I will raise the question of the political implications of our patterns of life and concomitant social “conceptual injustices”. Finally, I will show how imagining facts otherwise and other conceptual worlds can help us to reveal the prejudices and injustices of our concepts and can lead to conceptual change and new patterns of life that may ultimately even change “things”, i.e., our thinking, judging and acting in the world.

Abstract“A Misleading Parallel”. Wittgenstein on Conceptual Confusion in Psychology and the Semantics of Psychological Concepts. After the Philosophical Investigations, except for details, were largely finished in 1945, Wittgenstein, in his final years, undertook an intensive study of the grammar of our psychological concepts and the philosophical misinterpretations we often assign to them. Anyone looking through these extensive collections of philosophical remarks will probably quite often find it difficult to understand which questions Wittgenstein was addressing with individual remarks or groups of (...) remarks and where the philosophical problems lay for which he was trying to find a solution, whether therapeutic or otherwise appropriate.In the article at hand I do not claim to fathom the full range of Wittgenstein’s thoughts on the philosophy of psychology even in the most general way. Rather it is my intention to shed some light on a diagnosis which he made for the psychology of his time. In part 1 of this paper I would like to provide a brief sketch of what Wittgenstein considered to be the conceptual confusion prevalent in psychology and to suggest why he did not expect the methods of an experimental (natural) science to be successful in solving the problems that concern us in psychology. In part 2 I’ll attempt to analyze how psychological concepts, according to Wittgenstein, might be construed in order to avoid any type of conceptual confusion. (shrink)
