Current theories of the division of cognitive labor are confined to the “context of justification,” assuming exogenous theories. But new theories are made from the same labor that is used for developing existing theories, and if none of this labor is ever allocated to create new alternatives, then scientific progress is impossible. A unified model is proposed in which theories are no longer given but a function of the division of labor in the model itself. The interactions of individuals balancing (...) the exploitation of existing theories and the exploration of new theories results in a robust cyclical pattern. (shrink)

In a situation of peer disagreement, peers are usually assumed to share the same evidence. However they might not share the same evidence for the epistemic system used to process the evidence. This synchronic complication of the peer disagreement debate suggested by Goldman (In Feldman R, Warfield T (eds) (2010) Disagreement. Oxford University Press, Oxford, pp 187–215) is elaborated diachronically by use of a simulation. The Hegselmann–Krause model is extended to multiple epistemic systems and used to investigate the role of (...) consensus and difference splitting in peer disagreement. I find that the very possibility of multiple epistemic systems downgrades the epistemic value of consensus and makes difference splitting a suboptimal strategy. (shrink)

Academic and corporate research departments alike face a crucial dilemma: to exploit known frameworks or to explore new ones; to specialize or to innovate? Here I show that these two conflicting epistemic desiderata are sufficient to explain pluralistic ignorance and its boom-and-bust-like dynamics, exemplified in the collapse of the efficient markets hypothesis as a modern risk management paradigm in 2007. The internalist nature of this result, together with its robustness, suggests that pluralistic ignorance is an inherent feature rather than a (...) threat to the rationality of epistemic communities.

Kuhn wanted to install a new research agenda in philosophy of science. I argue that the tools are now available to better articulate his paradigm and let it guide philosophical research instead of itself remaining the object of philosophical debate.

Does science progress toward some goal or merely away from primitive beginnings? Two agent-based models are built to explain how possibly both kinds of progressive scientific change can result from the interactions of individuals exploring an epistemic landscape. These models are shown to result in qualitatively different predictions about what the resulting system of science should be like.

This article addresses the question how philosophy should be evaluated in a research-grant funding environment. It offers a new conception of philosophy that is inclusive and builds on familiar elements of professional, philosophical practice. Philosophy systematically questions the questions we ask, the concepts we use, and the values we hold. Its product is therefore rarely conclusive but can be embodied in everything we do. This is typical of explorative research and differentiates it from exploitative research, which constitutes the bulk of (...) funded research activity. This article argues that exploratory research is crucial for long-term progress and requires a distinct evaluative regime. (shrink)

According to Thomas Kuhn (1962/1970), science is characterized by two levels, one within and one between paradigms. The problem of Kuhnian rationality concerns the choice between paradigms, for which no rational basis appears to exist because this choice is inevitably circular to some extent. This is the main reason why Kuhn's view is perceived to glorify irrationality. (ibid. 199) I present two interpretations of the problem of Kuhnian rationality, one based on concepts (the neo-positivist interpretation) and one based on values. (...) I also describe two notions of rationality, optimizing and satisficing. Neither interpretation supports the notion of optimizing, but the values-interpretation supports satisficing, suggesting that if Kuhnian scientists are rational, as Kuhn insisted, they are satisficers. An agent-based model demonstrates that aggregating the behaviour of satisficing agents can account for Kuhn's view on the dynamics of scientific change. (shrink)

The lack of an account of rationality in The Structure of Scientific Revolutions was a lacuna which Thomas Kuhn acutely felt. In this paper, I argue that Herbert Simon’s notion of “satisficing” provides a formally well-developed and empirically well-established theory of rationality that fits well with Kuhn’s general characterization of science. I start by considering two rival interpretations of the problem of Kuhnian rationality and introduce Simon’s notion of satisficing. In Section 3, I show how satisficing can be used to (...) interpret paradigm, change, rational theory-choice, relativism, and progress. On this account, Kuhnian scientists are not irrational. Rather they employ the same computational mechanism which allows humans to play chess. (shrink)

We discuss a recent approach to investigating cognitive control, which has the potential to deal with some of the challenges inherent in this endeavour. In a model-based approach, the researcher defines a formal, computational model that performs the task at hand and whose performance matches that of a research participant. The internal variables in such a model might then be taken as proxies for latent variables computed in the brain. We discuss the potential advantages of such an approach for the (...) study of the neural underpinnings of cognitive control and its pitfalls, and we make explicit the assumptions underlying the interpretation of data obtained using this approach.

We present a model of the distribution of labour in science. Such models tend to rely on the mechanism of the invisible hand . Our analysis starts from the necessity of standards in distributed processes and the possibility of multiple standards in science. Invisible hand models turn out to have only limited scope because they are restricted to describing the atypical single-standard case. Our model is a generalisation of these models to J standards; single-standard models such as Kitcher are a (...) limiting case. We introduce and formalise this model, demonstrate its dynamics and conclude that the conclusions commonly derived from invisible hand models about the distribution of labour in science are not robust against changes in the number of standards.

Although compelling and insightful, the proposal by Uchiyama et al. largely neglects within-person change over time, arguably the central topic of interest within their framework. Longitudinal behavioural genetics modelling suggests that the heritability of trajectories is low, in contrast to high and increasing cross-sectional heritability across development. Better understanding of the mechanisms of trajectories remains a crucial outstanding challenge.

Every time we look around we can see a rich and detailed world surrounding us. Nevertheless, the majority of visual information seems to slip out of our thoughts instantly. Can we still say that this fleeting percept of the entire world was a conscious percept in the first place, as Block proposes?

This paper presents a framework for the generation of coherent elementary conversational sequences at the speech act level. We will embrace the notion of a cooperative dialogue game in which two players produce speech acts to transfer relevant information with respect to their commitments. Central to the approach is that participants try to achieve some sort of balanced cognitive state as a result of speech act generation and interpretation. Cognitive states of the participants change as a result of the interpretation (...) of speech acts and these changes provoke the production of a subsequent speech act. Describing the properties and the dynamics of the mental constructs that constitute the participants’ cognitive states, such as beliefs and commitments, in relation to the various dialogue contributions is an essential aspect of the game. Although simple in its basic form, the framework enables us to produce abstract conversations with some properties that agree strikingly with coherence structures found in, for instance, Conversation Analysis.

Can the straight line be analysed mathematically such that it does not fall apart into a set of discrete points, as is usually done but through which its fundamental continuity is lost? And are there objects of pure mathematics that can change through time? Mathematician and philosopher L.E.J. Brouwer argued that the two questions are closely related and that the answer to both is "yes''. To this end he introduced a new kind of object into mathematics, the choice sequence. But (...) other mathematicians and philosophers have been voicing objections to choice sequences from the start. This book aims to provide a sound philosophical basis for Brouwer's choice sequences by subjecting them to a phenomenological critique in the style of the later Husserl. (shrink)

In O'Regan & Noë's (O&N's) account for the phenomenal experience of seeing, awareness is equated to what is within the current focus of attention. They find no place for a distinction between phenomenal and access awareness. In doing so, they essentially present a dualistic solution to the mind-brain problem, and ignore that we do have phenomenal experience of what is outside the focus of attention.

Required reading for anyone who believes in the equality of the sexes. A long awaited, highly acclaimed new translation of Simone De Beauvoir's landmark work.

"Dans ses conférences annuelles à l'Université du Québec à Montréal, le philosophe flamand Jacques De Visscher dessine des figures de l'hospitalité à partir de lectures phénoménologiques d'oeuvres littéraires (Samuel Beckett, Albert Cohen, Franz Kafka, Jean-Marie Gustave Le Clézio, Paul van Ostaijen, Georges Perec, Marcel Proust) dans lesquelles il porte une attention particulière à la mise en scène architecturale, à la corporéité et à l'enracinement des choses dans notre monde ambiant. Il tente ainsi de nous prémunir d'une aliénation et d'un déracinement (...) qui appauvrissent nos relations avec autrui et notre être-au-monde."--From publisher's website. (shrink)
