Traditionally, conceptual thinking is explored via philosophical analysis or psychological experimentation. We seek to complement these mainstream approaches with the perspective of a first person exploration into pure thinking. To begin with, pure thinking is defined as a process and differentiated from its content, the concepts itself. Pure thinking is an active process and not a series of associative thought-events; we participate in it, we immerse ourselves within its active performance. On the other hand, concepts are also of an experiential (...) nature. And yet, little is known about what is it like to have or produce a thought, a concept, or an idea? Is a concept our own construction, a product of our own activity, or is it something we merely discover instead of producing it? We address these issues in a systematic first person enquiry into pure thinking. (shrink)

Models are not adequately evaluated simply by whether they capture the data, after the fact. Other criteria are needed. One criterion is parsimony; but utility and generality are at least as important. Even with respect to parsimony, however, the case against feedback is not as straightforward as Norris et al. present it. We use feedback consistency effects to illustrate these points.

Glenberg's conception of “meaning from and for action” is too narrow. For example, it provides no satisfactory account of the “logic of Elfland,” a metaphor used by Chesterton to refer to meaning acquired by being told something. All that we call spirit and art and ecstasy only means that for one awful instant we remember that we forget. G. K. Chesterton.

It is often assumed that graphemes are a crucial level of orthographic representation above letters. Current connectionist models of reading, however, do not address how the mapping from letters to graphemes is learned. One major challenge for computational modeling is therefore developing a model that learns this mapping and can assign the graphemes to linguistically meaningful categories such as the onset, vowel, and coda of a syllable. Here, we present a model that learns to do this in English for strings (...) of any letter length and any number of syllables. The model is evaluated on error rates and further validated on the results of a behavioral experiment designed to examine ambiguities in the processing of graphemes. The results show that the model (a) chooses graphemes from letter strings with a high level of accuracy, even when trained on only a small portion of the English lexicon; (b) chooses a similar set of graphemes as people do in situations where different graphemes can potentially be selected; (c) predicts orthographic effects on segmentation which are found in human data; and (d) can be readily integrated into a full-blown model of multi-syllabic reading aloud such as CDP++ (Perry, Ziegler, & Zorzi, 2010). Altogether, these results suggest that the model provides a plausible hypothesis for the kind of computations that underlie the use of graphemes in skilled reading. (shrink)

Using placebos in day-to-day practice is an ethical problem. This paper summarises the available epidemiological evidence to support this difficult decision. Based on these data we propose to differentiate between placebo and “knowledge framing”. While the use of placebo should be confined to experimental settings in clinical trials, knowledge framing — which is only conceptually different from placebo — is a desired, expected and necessary component of any doctor-patient encounter. Examples from daily practice demonstrate both, the need to investigate the (...) effects of knowledge framing and its impact on ethical, medical, economical and legal decisions. (shrink)

The noisy computation hypothesis of developmental dyslexia (DD) is particularly appealing because it can explain deficits across a variety of domains, such as temporal, auditory, phonological, visual and attentional processes. A key prediction is that noisy computations lead to more variable and less stable word representations. A way to test this hypothesis is through repetition of words, that is, when there is noise in the system, the neural signature of repeated stimuli should be more variable. The hypothesis was tested in (...) an functional magnetic resonance imaging experiment with dyslexic and typical readers by repeating words twelve times. Variability measures were computed both at the behavioral and neural levels. At the behavioral level, we compared the standard deviation of reaction time distributions of repeated words. At the neural level, in addition to standard univariate analyses and measures of intra-item variability, we also used multivariate pattern analyses (representational similarity and classification) to find out whether there was evidence for noisier representations in dyslexic readers compared to typical readers. Results showed that there were no significant differences between the two groups in any of the analyses despite robust results within each group (i.e., high representational similarity between repeated words, good classification of words vs. non-words). In summary, there was no evidence in favor of the idea that dyslexic readers would have noisier neural representations than typical readers. (shrink)

Zwischen den Schriften "Was ist Metaphysik?", " Vom Wesen des Grundes", "Kant und das Problem der Metaphysik", 1929, und "Platons Lehre von der Wahrheit", 1942, hat Heidegger nichts publiziert außer zwei kurzen Hölderlin-Vorträgen und seiner Rektoratsrede von 1933. In diesen dreizehn Jahren hat sowohl Heideggers Denkansatz als auch seine Denkhaltung eine Veränderung erfahren; es ist die in der Heidegger-Forschung so genannte "Kehre". Seit der 1976 aus dem Nachlaß begonnenen Herausgabe von Heideggers Vorlesungen fällt von Mal zu Mal mehr Licht auf (...) seinen Denkweg in besagter Zeitspanne. Zu Recht wurde die Vorlesung als die "Heideggers philosophisches Schaffen zentral prägende Darstellungsform" bezeichnet. Studiert man die Vorlesungen, so wird klar, wie es dazu kommt, daß Heideggers Denkwege in dieser Zeit oft "jäh im Unbegangenen aufhören"; so das Motto des Buches "Holzwege", das, 1950 erschienen, Vorträge und Aufsätze aus der Zeit von 1935 bis 1946 enthält.Die These der Autorin lautet: Der Grund für Heideggers gewandeltes Denken am Ende der genannten Zeitspanne besteht in Erfahrungen, die er im Gespräch mit Hölderlin seit der Vorlesung von 1934/35 gemacht hat. Was sich zwischen 1934/35 und der Heraklit-Vorlesung von 1944 abspielt und als "Kehre" angesprochen wird, bereitet Heideggers Denken vor, wie es in "Vorträge und Aufsätze", "Unterwegs zur Sprache" und in allen späteren Schriften zum Ausdruck kommt.Die Vorlesungen ab 1934/35 zeigen drei Schwerpunkte: die Auseinandersetzung mit Hölderlin, mit Nietzsche und mit den griechischen Denkern am Anfang der abendländischen Geschichte. Während die Philosophie Nietzsches in Heideggers Augen die Vollendung des mit Platon beginnenden Zeitalters der Metaphysik artikuliert, kündigt sich in der Dichtung Hölderlins der Anfang einer anderen Geschichte an. Diesen anderen Geschichtsanfang sieht Heidegger in einem Spannungsverhältnis zu dem, was die griechischen anfänglichen Denker gesagt haben. Ihre Gedanken legt er als ein Sprechen aus dem Erfahrungsbereich der Ἀλήθεια aus. Hölderlin und die Ἀλήθεια stehen also, in je verschiedener, jedoch aufeinander bezogener Weise, für den Anfang von Geschichte. Es ist Heideggers Überzeugung, daß sich Geschichte aus ihrem Anfang bleibend bestimmt. In der Untersuchung wird die Herkunft dieser Überzeugung aufgespürt, was auch irn Hinblick auf die unveröffentlichte Abhandlung von 1941 "Über den Anfang" von Bedeutung ist.Die Verfasserin legt den Boden frei, aus dem das Denken von Heideggers Spätschriften erwächst. Dazu analysiert sie die Freiburger Vorlesungen zwischen 1934/35 und 1944. Es geht ihr darum, die zentralen Gedanken Heideggers in statu nascendi und in ihrer Entfaltung, in ihrer Kontinuität und Veränderung zu verfolgen. Eine solche Verfahrensweise ist um so mehr geboten, als in vielen bisherigen Forschungsarbeiten der Wegcharakter von Heideggers Denken nicht ernst genommen wird und frühere Positionen mit späteren unachtsam vermischt werden. Beachtet man dagegen das Weghafte dieses Denkens, so kann eine Reihe gängiger Forschungsmeinungen korrigiert werden. Zum Beispiel tritt die Zeit-Thematik in Heideggers Spätphilosophie keineswegs "deutlich in den Hintergrund", sie hält sich vielmehr unter gewandelten Namen bis ans Ende seines Denkweges durch.

This chapter argues that recent attempts to make sense of the delusion of thought insertion in terms of a distinction between two notions of thought ownership have been unsuccessful. It also proposes an alternative account, in which the delusion is to be interpreted in the light of its prehistory.

Si l’on connaît aujourd’hui le dialogue fructueux que Paul Ricœur a noué avec les penseurs structuralistes, on ignore largement son positionnement face à la mouvance poststructuraliste. Faut-il opposer la philosophie de Ricœur au poststructuralisme à la française ou au contraire doit-on montrer qu’elle en est une variante singulière? C’est la seconde option qui est ici défendue. Certes, le poststructuralisme ne doit pas être considéré comme une école de pensée mais comme une reconstruction qui relève de l’histoire de la philosophie. Dans (...) la mesure où les horizons de dépassement du structuralisme ont été posés de manière chaque fois particulière, il est préférable de parler de poststructuralismes au pluriel. C’est la raison pour laquelle J. Michel propose des confrontations dyadiques entre Ricœur et certains de ses contemporains que l’on regroupe habituellement dans cette mouvance. (shrink)

This article outlines different attempts to define integrity, and argues, with reference to the theory of moral particularism, that definitions acquire universal applicability at the expense of their informative value. The article then proceeds to more delimitating definitions that emphasise the social aspect, and argues that their ideas of the concept, like courage, require certain situations in order to unfold. Since not every person is challenged to act with integrity, the delimitation requires a distinction between manifest integrity and dormant integrity, (...) or dormant lack of integrity. Persons of influence, like politicians and managers, on the other hand, are challenged on a regular basis because their position requires communication of values in a public space, against which the public can evaluate their actions. A delimitating definition therefore ties the question of integrity to people in leading positions. (shrink)

Noam Chomsky and Frances Egan argue that David Marr’s computational theory of vision is not intentional, claiming that the formal scientific theory does not include description of visual content. They also argue that the theory is internalist in the sense of not describing things physically external to the perceiver. They argue that these claims hold for computational theories of vision in general. Beyond theories of vision, they argue that representational content does not figure as a topic within formal computational theories (...) in cognitive science. I demonstrate that Chomsky’s and Egan’s claims about Marr’s theory are false. Marr’s computational theory contains a mathematical theory of visual content, based on empirical psychophysical evidence. It also contains mathematical descriptions of distal physical surfaces and objects, and of their optic projection to the perceiver. Much computational research on vision contains these types of intentional and externalist components within the formal, mathematical, theories. Chomsky’s and Egan’s claims demonstrate inadequate study and understanding of Marr’s work and other research in this area. Computational theories of vision, by containing empirically based mathematical theories of visual content, to this extent present naturalizations of semantics. (shrink)

We claim that adjustable parameters play a crucial role in building and applying simulation models. We analyze that role and illustrate our findings using examples from equations of state in thermodynamics. In building simulation models, two types of experiments, namely, simulation and classical experiments, interact in a feedback loop, in which model parameters are adjusted. A critical discussion of how adjustable parameters function shows that they are boon and bane of simulation. They help to enlarge the scope of simulation far (...) beyond what can be determined by theoretical knowledge, but at the same time undercut the epistemic value of simulation models. (shrink)
