The book’s core argument is that an artificial intelligence that could equal or exceed human intelligence—sometimes called artificial general intelligence (AGI)—is for mathematical reasons impossible. It offers two specific reasons for this claim: Human intelligence is a capability of a complex dynamic system—the human brain and central nervous system. Systems of this sort cannot be modelled mathematically in a way that allows them to operate inside a computer. In supporting their claim, the authors, Jobst Landgrebe and Barry Smith, marshal evidence (...) from mathematics, physics, computer science, philosophy, linguistics, and biology, setting up their book around three central questions: What are the essential marks of human intelligence? What is it that researchers try to do when they attempt to achieve "artificial intelligence" (AI)? And why, after more than 50 years, are our most common interactions with AI, for example with our bank’s computers, still so unsatisfactory? Landgrebe and Smith show how a widespread fear about AI’s potential to bring about radical changes in the nature of human beings and in the human social order is founded on an error. There is still, as they demonstrate in a final chapter, a great deal that AI can achieve which will benefit humanity. But these benefits will be achieved without the aid of systems that are more powerful than humans, which are as impossible as AI systems that are intrinsically "evil" or able to "will" a takeover of human society.

A common philosophical account of expertise contends that (a) the good of expertise lies in the fact that it is grounded in reliably true beliefs or knowledge in a domain and (b) rejecting this truth-linked view threatens the authority of experts and opens one to epistemic relativism. I argue that both of these claims are implausible, and I show how epistemic authority and objectivity can be grounded in the current state of understanding and skill in a domain. Further, I argue (...) that what I call a ‘cognitive systems’ approach is consistent with this domain-linked account of expert authority, is empirically supported, and provides a philosophical foundation for both empirical and conceptual work on the nature and scope of expertise.

The ecological realist concept of information as environmental specification is discussed. It is argued that affordances in ecological realism could, in principle, rest on a notion of partial specification of environmental circumstances. For this aim, a notion of Gestalt quality as a hierarchical structure of affordances would have to be adopted. It is claimed that such an account could provide a promising way to deal with problems of intentionality in perception and action, awareness and problem solving.

This article focuses on an area of study that may be called folk economics and that is currently not on the social science agenda. Folk economics has as its task to analyze and explain how people view the economy and how it works; what categories they use in doing so; and what effect this has on the economy and society. Existing studies in economics and sociology that are relevant to this type of study are presented and discussed. A theoretical framework (...) for analyzing folk economic issues is suggested, centered on the distinction between episteme and doxa or between scientific knowledge, on the one hand, and everyday knowledge, on the other. This is then applied to an exploratory case study of the role that folk economics played in Trump’s presidential campaign. It is shown that Trump and his voters thought in a parallel way on key economic issues, especially protectionism. (shrink)

In this article, we propose that gestures play an important role in the connection between sensorimotor experience and language. Gestures may be the link between bodily experience and verbal expression that advocates of embodied cognition have postulated. In a developmental sequence of communicative action, gestures, which are initially similar to action sequences, substantially shorten and represent actions in metonymic form. In another process, action sequences are based on kinesthetic schemata that themselves find their metaphoric expression in language. Again, gestures enact (...) kinesthetic schemata that are correlated with verbal expressions. Examples from a large database are used to illustrate the various processes by means of which language arises when students conduct school science investigations. (shrink)

In the 1980s naive physics almost suddenly became a field of research for physicists interested in teaching and experimental psychologists. Such research, however, was limited to accurately recording the bizarre Aristotelian responses of “layman” struggling with simple physics issues. Another research on this topic is that one of phenomenological origin: starting from the studies of the psychologist of perception Paolo Bozzi naive physics had entered the laboratory, and he was the first to find that the physical knowledge of the adult (...) individuals were “Aristotelian”. Bozzi took advantage of these results in order to hypothesize a substantial diversity and independence of the sensory system with respect to the cognitive-rational one. Other interesting perspectives were considered by Piaget, who in the 1980s, confirming the spontaneous Aristotelism of children, provided a still prolific epistemological direction of such investigations: finding an explanatory mechanism that projects on the level of science construction that one of individual cognitive development.

In this paper I will discuss some issues related to a recent trend in experimental philosophy (or x-phi), and try to show the reasons of its late (and scarce) involvement with aesthetics, compared to other areas of philosophical investigation. In order to do this, it is first necessary to ask how an autonomous experimental philosophy of aesthetics could be related to the long-standing tradition of psychological experimental aesthetics. After distinguishing between a “narrow” and a “broad” approach of experimental philosophy, I (...) will then make a distinction between topics in aesthetics pertaining to perceptual and cognitive processes, and traditional issues involved in the analysis of general and culturally-laden concepts. The narrow program of experimental philosophy, focused on the investigation of folk intuitions, is particularly effective only when two general conditions are met: the use of hypothetical scenarios (testing of thought experiments) and the heuristic role of folk intuitions in drawing philosophically relevant conclusions. I will argue that, when aesthetics is concerned, these requirements are not easily met. These difficulties notwithstanding, I will support a pluralistic view where aesthetics is revealed as an instructive example of how experimental approaches and traditional “armchair” philosophy integrate, and enrich each other.

The view that the mind-dependence of colour is implicit in our ordinary thinking has a distinguished history. With its origins in Berkeley, the view has proved especially popular amongst so-called ‘Oxford’ philosophers, proponents including Cook Wilson (1904: 773-4), Pritchard (1909: 86-7), Ryle (1949: 209), Kneale (1950: 123) and McDowell (1985: 112). Gareth Evans’s discussion of secondary qualities in “Things Without the Mind” is representative of this tradition. It is his version of the view that I consider in this paper.

Commonsense ontology often conflicts with the ontology of our best scientific and philosophical theories. However, commonsense ontology, and commonsense belief systems in general, seems to be remarkably efficient and cognitively fundamental. In cases of contrast, it is better to find a way to reconcile commonsense and ”theoretical” ontologies. Given that commonsense ontologies are typically expressed within natural language, a classical procedure of reconciliation is semantical. The strategy is that of individuating the ”ontologically problematic” expressions of natural language and paraphrasing the (...) sentences in which they appear in a (formal) language whose commitments are compatible with those of our best theories. We believe that this strategy of reconciliation, though quite standard, especially in the philosophical literature, is problematic: for a start, it forces us to conclude that the ”real content” of our commonsense expressions and beliefs is different from what it appears. Commonsense ontology becomes just an illusion. We will thus propose an alternative approach: according to our view, a commonsense ontology is reconciled with a theoretical ontology in case it is shown that the explanation of why we believe in the existence of a problematic entity is compatible with our best theories. We will call this kind of reconciliation ”epistemic”. The advantage of an epistemic reconciliation is that commonsense ontology is treated in its own right and could be taken prima facie. Another advantage of the view is that epistemic reconciliation can be analysed through the notion of explaining away: a commonsense ontology is epistemically reconciled with a theoretical ontology if and only if the problematic entities of the commonsense ontology are explained away by ”respectable” entities of the theoretical ontology. In the final part of the paper, we sketch a formal analysis of explaining away. (shrink)

We presuppose a position of scientific realism to the effect (i) that the world exists and (ii) that through the working out of ever more sophisticated theories our scientific picture of reality will approximate ever more closely to the world as it really is. Against this background consider, now, the following question: 1. Do the empirical theories with the help of which we seek to approximate a good or true picture of reality rest on any non-empirical presuppositions? One can answer (...) this question with either a 'yes' or a 'no'. 'No' is the preferred answer of most contemporary methodologists -- Murray Rothbard is one distinguished counterexample to this trend -- who maintain that empirical theories are completely free of non-empirical ('a priori') admixtures and who see science as a matter of the gathering of pure 'data' obtained through simple observation. From such data scientific propositions are then supposed to be somehow capable of being established. (shrink)

The paper introduces the concepts at the heart of point-set-topology and of mereotopology (topology founded in the non-atomistic theory of parts and wholes) in an informal and intuitive fashion. It will then seek to demonstrate how mereotopological ideas can be of particular utility in cognitive science applications. The prehistory of such applications (in the work of Husserl, the Gestaltists, of Kurt Lewin and of J. J. Gibson) will be sketched, together with an indication of the field of possibilities in linguistics, (...) perceptual psychology, cate¬gorization and geographic information systems. Topological structures will be shown to play a central role in studies of naive physics not least in virtue of the fact that even well-attested departures from true physics on the part of common sense leave the topology and vectorial orientation of the underlying physical phenomena invariant: our common sense would thus seem to have a veridical grasp of the topology and broad general orientation of physical phenomena, both static and dynamic, even where it illegitimately modifies the relevant shape and metric properties. The implications of this and related insights for the methodology of psychology will be explored. (shrink)

Common sense is on the one hand a certain set of processes of natural cognition - of speaking, reasoning, seeing, and so on. On the other hand common sense is a system of beliefs (of folk physics, folk psychology and so on). Over against both of these is the world of common sense, the world of objects to which the processes of natural cognition and the corresponding belief-contents standardly relate. What are the structures of this world? How does the scientific (...) treatment of this world relate to traditional and contemporary metaphysics and formal ontology? Can we embrace a thesis of common-sense realism to the effect that the world of common sense exists uniquely? Or must we adopt instead a position of cultural relativism which would assign distinct worlds of common sense to each group and epoch? The present paper draws on recent work in computer science (especially in the fields of naive and qualitative physics), in perceptual and developmental psychology, and in cognitive anthropology, in order to consider in a new light these and related questions and to draw conclusions for the methodology and philosophical foundations of the cognitive sciences.

While contemporary philosophers have devoted vast amounts of attention to the language we use in describing and finding our way about the world of everyday experience, they have, with few exceptions, refused to see this world itself as a fitting object of theoretical concern. In what follows I shall seek to show how the commonsensical world might be treated ontologically as an object of investigation in its own right. At the same time I shall seek to establish how such a (...) treatment might help us better philosophically to understand the structures of both physical reality and cognition. (shrink)

One’s life can be meaningful, but not worth living, or worth living, but not meaningful, which demonstrates that an evaluation of whether life is worth living differs from an evaluation of whether one’s life is meaningful. But how do these evaluations differ? As I will argue, an evaluation of whether life is worth living is a more comprehensive evaluation than the evaluation of whether one’s individual life is meaningful. In judging whether one finds life worth living, one takes into account, (...) not only whether one’s life is meaningful, but undesirable aspects of life such as chronic pain and suffering. For example, a person who is suffering greatly, but who has lived a meaningful life, might still conclude that his or her life is not worth living. Although the famed question about the meaning of life has received most of the attention, I argue that the better and more fruitful question is “Is life worth living?” One should want, not just for one’s life to be meaningful, but for it to be worth living.
