The influential threat simulation theory asserts that dreaming yields adaptive advantage by providing a virtual environment in which threat-avoidance may be safely rehearsed. We have previously found the incidence of biologically threatening dreams to be around 20%, with successful threat avoidance occurring in approximately one-fifth of such dreams. TST asserts that threat avoidance is over-represented relative to other possible dream contents. To begin assessing this issue, we contrasted the incidence of ‘avoidance’ dreams with that of their opposite: ‘approach’ dreams. Because (...) TST states that the threat-avoidance function is only fully activated in ecologically valid contexts, we also performed this contrast for populations living in both high- and low-threat environments. We find that ‘approach’ dreams are significantly more prevalent across both contexts. We suggest these results are more consistent with the view that dreaming is generated by reward-seeking systems than by fear-conditioning systems, although reward-seeking is clearly not the only factor determining the content of dreams.

We consider the evidence that RA†, the vitamin A metabolite, is involved in three fundamental aspects of the development of the CNS: (1) the stimulation of axon outgrowth in particular neuronal sub‐types; (2) the migration of the neural crest; and (3) the specification of rostrocaudal position in the developing CNS (forebrain, midbrain, hindbrain, spinal cord). The evidence we discuss involves RA‐induction of neurites in cell cultures and explants of neural tissue; the teratological effects of RA on the embryo's nervous system; (...) the observation that RA can be detected endogenously in the spinal cord; and the fact that the receptors and binding proteins for RA are expressed in precise domains and neuronal cell types within the nervous system.

The philosophy of memory has been largely dominated by what could be called ‘the representative theory of memory’. In trying to give an account of ‘what goes on in one's mind’ when one remembers something, or of what ‘the mental content of remembering’ consists, philosophers have usually insisted that there must be some sort of mental image, picture, or copy of what is remembered. Aristotle said that there must be ‘something like a picture or impression’; William James thought that there (...) must be in the mind 'an image or copy’ of the original event; Russell said that ‘Memory demands an image’. In addition to the image or copy a variety of other mental phenomena have been thought to be necessary. In order for a memory image to be distinguished from an expectation image, the former must be accompanied by ‘a feeling of pastness’. One has confidence that the image is of something that actually occurred because the image is attended by ‘a feeling of familiarity’. And in order that you may be sure that the past event not merely occurred but that you witnessed it, your image of the event must be presented to you with a feeling of ‘warmth and intimacy’. When all the required phenomena are put together, the mental content of remembering turns out to be, as William James says, ‘a very complex representation’. (shrink)

For some time, the role of culture in language education within schools, universities and professional communication has received increasing attention. This article identifies two aporias in the discourse of intercultural communication : first, that it contains an unstated movement towards a universal consciousness; second, that its claims to truth are grounded in an implicit appeal to a transcendental moral signified.These features constitute IC discourse as ‘totality’, or as ‘metaphysics of presence’.The article draws on the work of Levinas ; and Derrida (...) to propose more considered ethical grounds for intercultural praxis. Contra a Hegelian impetus towards universal consciousness,we posit an irreducible distance and separation between the self and other. In so doing, not only are we able to supersede the field’s implicit appeal to the transcendental as a source of truth but also to counter perceptibly ‘exorbitant’ claims and actions of the intercultural other. In this vein, the article proposes a discourse ethics of responsibility by which it still becomes possible for a critical intercultural praxis to make value judgements and to take potentially transformative action vis-à-vis cultural acts that challenge the limits of intercultural tolerance and hospitality.

This paper compares Wittgenstein's conception of ?objective certainty? with Descartes's ?metaphysical certainty?. According to both conceptions if you are certain of something in these senses, then it is inconceivable that you are mistaken. But a striking difference is that for Descartes, if you are metaphysically certain of something it follows both that the something is so and that you know it is so; whereas on Wittgenstein's conception neither thing follows. I try to show that there is a form of ?scepticism? (...) in Wittgenstein's outlook on the concept of certainty, although it is not the familiar Philosophical Scepticism. The Appendix takes issue with a recent essay by John Cook which argues that the ?hinge propositions? of On Certainty are based on ?the metaphysics of phenomenalism? (shrink)

Offers an introduction to Hobbes's life, paying special attention to his family background, his education, his relations with his employers, and his connections with the various intellectual groups, which may have influenced his thinking—such as the ‘Great Tew’ circle in England, and the Mersenne circle in France. It also discusses the notoriety that followed the publication of Leviathan in 1651, and the polemics that dogged his later years.

Wayne Myrvold (2003) has captured an important feature of unified theories, and he has done so in Bayesian terms. What is not clear is whether the virtue of such unification is most clearly understood in terms of Bayesian confirmation. I argue that the virtue of such unification is better understood in terms of other truth-related virtues such as predictive accuracy.

Wenig ist bekannt über Leibniz' Reise 1676 nach Holland, und der wichtigste Teil dieser Reise -sein Treffen mit Spinoza im Haag -bleibt ziemlich im Dunkeln. Ein erst kürzlich veröffentlichter Brief von Leibniz an Oldenburg, verfasst kurz nach seinem Besuch bei Spinoza, liefert nicht nur mehr Information über Leibniz' Aufenthalt in Holland (und seiner vorrangegangenen Reise nach England), sondern er wirft auch etwas mehr Licht auf seine Haltung zu Spinoza in dieser Zeit. In diesem Aufsatz wird dargelegt, wie Leibniz' Versäumnis, einen (...) Brief von Oldenburg an Spinoza zu übermitteln, wahrscheinlich verursacht wurde durch einige Bemerkungen in diesem Brief, die Leibniz als einen Sympathisanten der Philosophie Spinozas darstellten. Es wird weiterhin diskutiert, welcher Art diese Sympathien hätten sein können und worin das Widerstreben auf Leibniz' Seite bestand, als Anhänger Spinozas erkannt zu werden. (shrink)

I believe that Mr. Sosa is right about my example but wrong on the substantive issue; which shows that my example was poorly chosen. If the ugliest Irishman was so ugly that even the Irish were offended, they might form a committee to get rid of him. Suppose he was kidnapped and deposited in New York. If we were informed of all this and also knew that the ugliest Irishman is the Prime Minister, I agree that we should have been (...) given an adequate explanation of why the Prime Minister is in New York.

Noel Malcolm presents his long-awaited critical edition of one of the most important philosophical works ever written. Hobbes's Leviathan (1651) is a classic of political theory and of English prose, studied at every university in the world. The English and Latin versions of the text are fully annotated, with a book-length introduction.

How does it come about that a novel containing thousands of moral statements is seldom critically examined from a moral point of view? In his inaugural lecture, Professor Bowie presents Proust's narrator as a moral theorist obsessively concerned with the definition of virtue and vice. Bowieargues not just that the moral language of Proust is sufficiently strange and provocative to repay close study but that A la recherche du temps perdu has a distinctive moral architecture which deserves to be included (...) among the wonders of the Proustian world. Bowie's account of Proustian virtue,especially as it appears in the culminating pages of Le Temps retrouve, casts an entirely new light upon the much discussed themes of memory and desire in the novel.

This article discusses the role of human-created rules in our collective adapting to Covid-19 and our survival in its wake. Rules that make sense become institutionalised and play a dual role in our response to the pandemic: they provide a guide for individual behavior and they provide a mechanism for coordinating all our behaviors.
