In many educational systems, ethnic minority students score lower in their academic achievement, and consequently, teachers develop low expectations regarding this student group. Relatedly, teachers’ implicit attitudes, explicit expectations, and causal attributions also differ between ethnic minority and ethnic majority students—all in a disadvantageous way for ethnic minority students. However, what is not known so far, is how attitudes and causal attributions contribute together to teachers’ judgments. In the current study, we explored how implicit attitudes and causal attributions contribute to (...) preservice teachers’ judgments of the low educational success of an ethnic minority student. Results showed that both implicit attitudes and causal attributions predicted language proficiency and intelligence judgments. Negative implicit attitudes, assessed with the IRAP, and internal stable causal attributions led to lower judgments of language proficiency, whereas lower judgments of intelligence were predicted by positive implicit attitudes and higher judgments of intelligence by external stable attributions. Substantial differences in the prediction of judgments could be found between the IRAP and BIAT as measures of implicit attitudes. (shrink)

Stephen Cole Kleene was one of the greatest logicians of the twentieth century and this book is the influential textbook he wrote to teach the subject to the next generation. It was first published in 1952, some twenty years after the publication of Godel's paper on the incompleteness of arithmetic, which marked, if not the beginning of modern logic. The 1930s was a time of creativity and ferment in the subject, when the notion of computable moved from the realm of (...) philosophical speculation to the realm of science. This was accomplished by the work of Kurt Gode1, Alan Turing, and Alonzo Church, who gave three apparently different precise definitions of computable. When they all turned out to be equivalent, there was a collective realization that this was indeed the right notion. Kleene played a key role in this process. One could say that he was there at the beginning of modern logic. He showed the equivalence of lambda calculus with Turing machines and with Godel's recursion equations, and developed the modern machinery of partial recursive functions. This textbook played an invaluable part in educating the logicians of the present. It played an important role in their own logical education.". (shrink)

The Swedish artist and writer Tyra Kleen was a professional artist and a constant traveller who had a great interest in different religious questions. This article describes her Symbolist artistry, her interest in Theosophy and her journeys to India and Asia.

Undergraduate students with no prior classroom instruction in mathematical logic will benefit from this evenhanded multipart text by one of the centuries greatest authorities on the subject. Part I offers an elementary but thorough overview of mathematical logic of first order. The treatment does not stop with a single method of formulating logic; students receive instruction in a variety of techniques, first learning model theory (truth tables), then Hilbert-type proof theory, and proof theory handled through derived rules. Part II supplements (...) the material covered in Part I and introduces some of the newer ideas and the more profound results of logical research in the twentieth century. Subsequent chapters introduce the study of formal number theory, with surveys of the famous incompleteness and undecidability results of Godel, Church, Turing, and others. The emphasis in the final chapter reverts to logic, with examinations of Godel's completeness theorem, Gentzen's theorem, Skolem's paradox and nonstandard models of arithmetic, and other theorems. Unabridged republication of the edition published by John Wiley & Sons, Inc. New York, 1967. Preface. Bibliography. Theorem and Lemma Numbers: Pages. List of Postulates. Symbols and Notations. Index.

§1. The origins of recursion theory. In dedicating a book to Steve Kleene, I referred to him as the person who made recursion theory into a theory. Recursion theory was begun by Kleene's teacher at Princeton, Alonzo Church, who first defined the class of recursive functions; first maintained that this class was the class of computable functions ; and first used this fact to solve negatively some classical problems on the existence of algorithms. However, it was Kleene who, in his (...) thesis and in his subsequent attempts to convince himself of Church's Thesis, developed a general theory of the behavior of the recursive functions. He continued to develop this theory and extend it to new situations throughout his mathematical career. Indeed, all of the research which he did had a close relationship to recursive functions.Church's Thesis arose in an accidental way. In his investigations of a system of logic which he had invented, Church became interested in a class of functions which he called the λ-definable functions. Initially, Church knew that the successor function and the addition function were λ-definable, but not much else. During 1932, Kleene gradually showed1 that this class of functions was quite extensive; and these results became an important part of his thesis 1935a. (shrink)

I defend the normativity of meaning against recent objections by arguing for a new interpretation of the ‘ought’ relevant to meaning. Both critics and defenders of the normativity thesis have understood statements about how an expression ought to be used as either prescriptive or semantic. I propose an alternative view of the ‘ought’ as conveying the primitively normative attitudes speakers must adopt towards their uses if they are to use the expression with understanding.

Although Hannah Arendt is considered one of the major contributors to social and political thought in the twentieth century, this is the first general anthology ...

It has been hypothesized that our believing that, or its seeming to us as though, the world is in some way dynamical partially explains (and perhaps rationalizes) future-bias. Recent work has, in turn, found a correlation between future-bias and near-bias, suggesting that there is a common explanation for both. Call the claim that what partially explains our being both future- and near-biased is our believing/it seeming to us as though the world is dynamical, the dynamical explanation. We empirically test two (...) versions of the dynamical explanation. The first is the moving ego explanation—according to which it is our belief that the ego moves, or our phenomenology as of the ego moving, that jointly (partially) explains future- and near-bias. The second is the moving time explanation—according to which it is our belief that time robustly passes, or our phenomenology as of robust passage, which jointly (partially) explain future- and near-bias. We found no evidence in favour of either explanation. (shrink)

A unique selection of the most significant interviews given by Hannah Arendt, including the last she gave before her death in 1975. Some are published here in English for the first time. Arendt was one of the most important thinkers of her time, famous for her idea of "the banality of evil" which continues to provoke debate. This collection provides new and startling insight into Arendt's thoughts about Watergate and the nature of American politics, about totalitarianism and history, and (...) her own experiences as an emigre. Hannah Arendt: The Last Interview and Other Conversations is an extraordinary portrait of one of the twentieth century's boldest and most original thinkers. As well as Arendt's last interview with French journalist Roger Errera, the volume features an important interview from the early 60s with German journalist Gunter Gaus, in which the two discuss Arendt's childhood and her escape from Europe, and a conversation with acclaimed historian of the Nazi period, Joachim Fest, as well as other exchanges. These interviews show Arendt in vigorous intellectual form, taking up the issues of her day with energy and wit. She offers comments on the nature of American politics, on Watergate and the Pentagon Papers, on Israel; remembers her youth and her early experience of anti-Semitism, and then the swift rise of the Hitler; debates questions of state power and discusses her own processes of thinking and writing. Hers is an intelligence that never rests, that demands always of her interlocutors, and her readers, that they think critically. As she puts it in her last interview, just six months before her death at the age of 69, "there are no dangerous thoughts, for the simple reason that thinking itself is such a dangerous enterprise.".
