When K. Grue-Sørensen became a professor of pedagogy at the University of Copenhagen in 1955, he was inline with the dominant historical-hermeneutical approach to humanities. From the late 1960s until retirementin 1974, his approach was challenged by both technical and critical alternatives. Both these alternative havesince grown steadily, while the historical-hermeneutical view has been in the defensive. But Grue-Sørensenand the tradition he represented have three signifi cant points for today’s pedagogy, whether it is technicalor critical: pedagogy can and (...) should not deliver effi ciency technology, pedagogy should as far as possible useeveryday language, and fi nally that the educational history can make us wiser.

Next SectionSome argue that genetic enhancements and environmental enhancements are not importantly different: environmental enhancements such as private schools and chess lessons are simply the old-school way to have a designer baby. I argue that there is an important distinction between the two practices—a distinction that makes state restrictions on genetic enhancements more justifiable than state restrictions on environmental enhancements. The difference is that parents have no settled expectations about genetic enhancements.

Can God create a stone too heavy for him to lift? Can time have a beginning? Which came first, the chicken or the egg? Riddles, paradoxes, conundrums--for millennia the human mind has found such knotty logical problems both perplexing and irresistible. Now Roy Sorensen offers the first narrative history of paradoxes, a fascinating and eye-opening account that extends from the ancient Greeks, through the Middle Ages, the Enlightenment, and into the twentieth century. When Augustine asked what God was doing before (...) He made the world, he was told: "Preparing hell for people who ask questions like that." A Brief History of the Paradox takes a close look at "questions like that" and the philosophers who have asked them, beginning with the folk riddles that inspired Anaximander to erect the first metaphysical system and ending with such thinkers as Lewis Carroll, Ludwig Wittgenstein, and W.V. Quine. Organized chronologically, the book is divided into twenty-four chapters, each of which pairs a philosopher with a major paradox, allowing for extended consideration and putting a human face on the strategies that have been taken toward these puzzles. Readers get to follow the minds of Zeno, Socrates, Aquinas, Ockham, Pascal, Kant, Hegel, and many other major philosophers deep inside the tangles of paradox, looking for, and sometimes finding, a way out. Filled with illuminating anecdotes and vividly written, A Brief History of the Paradox will appeal to anyone who finds trying to answer unanswerable questions a paradoxically pleasant endeavor.

Can merely thinking about an imaginary situation provide evidence for how the world actually is--or how it ought to be? In this lively book, Roy A. Sorensen addresses this question with an analysis of a wide variety of thought experiments ranging from aesthetics to zoology. Presenting the first general theory of thought experiment, he sets it within an evolutionary framework and integrates recent advances in experimental psychology and the history of science, with special emphasis on Ernst Mach and Thomas Kuhn. (...) Sorensen explores what thought experiments are, how they work, and what their virtues and vices are. In his view, philosophy differs from science in degree, but not in kind. For this reason, he claims, it is possible to understand philosophical thought experiments by concentrating on their resemblance to scientific relatives. Sorensen assesses the hazards of thought experiments and grants that there are interesting ways in which the method leads us astray, but attacks most scepticism about thought experiments as arbitrary. He maintains that they should be used--as they generally are--as part of a diversified portfolio of techniques, creating a network of cross-checks that make for impressive reliability. (shrink)

In ”Formal Problems about Knowledge,” Roy Sorensen examines epistemological issues that have logical aspects. He uses Fitch's proof for unknowables and the surprise test paradox to illustrate the hopes of the modal logicians who developed epistemic logic, and he considers the epistemology of proof with the help of the knower paradox. One solution to this paradox is that knowledge is not closed under deduction. Sorensen reviews the broader history of this maneuver along with the relevant alternatives model of knowledge which (...) assumes that ”know” is an absolute term like ”flat.” Sorensen argues that the difference between epistemic absolute terms and extensional absolute terms gives rise to an asymmetry that undermines recent claims that there is a structural parallel between the supervaluational and epistemicist theories of vagueness, and he suggests that we have overestimated the ability of logical demonstration to produce knowledge.

In this book, Sorensen presents the first general theory of the thought experiment. He analyses a wide variety of thought experiments, ranging from aesthetics to zoology, and explores what thought experiments are, how they work, and what their positive and negative aspects are. Sorensen also sets his theory within an evolutionary framework and integrates recent advances in experimental psychology and the history of science.

An entertaining history of the idea of nothing - including absences, omissions, and shadows - from the Ancient Greeks through the 20th century How can nothing cause something? The absence of something might seem to indicate a null or a void, an emptiness as ineffectual as a shadow. In fact, 'nothing' is one of the most powerful ideas the human mind has ever conceived. This short and entertaining book by Roy Sorensen is a lively tour of the history and philosophy (...) of nothing, explaining how various thinkers throughout history have conceived and grappled with the mysterious power of absence -- and how these ideas about shadows, gaps, and holes have in turned played a very positive role in the development of some of humankind's most important ideas. Filled with Sorensen's characteristically entertaining mix of anecdotes, puzzles, curiosities, and philosophical speculation, the book is ordered chronologically, starting with the Taoists, the Buddhists, and the ancient Greeks, moving forward to the middle ages and the early modern period, then up to the existentialists and present day philosophy. The result is a diverting tour through the history of human thought as seen from a novel and unusual perspective. (shrink)

A Brief History of the Paradox is the first narrative history of paradoxes.

'Pataphysics: The Poetics of an Imaginary Science is a survey that attempts to describe a hypothetic philosophy--the avant-garde pseudo-science imagined by Alfred Jarry. 'Pataphysics is a supplement to metaphysics, accenting it, then replacing it, in order to create a philosophic alternative, whose discipline can study cases, not of conception, but of exception: variance , alliance , and deviance . 'Pataphysics synthesizes the romantic schism between a literal, scientized discourse and a figural, poeticized discourse, and my thesis suggests that this revision (...) of the signifier "science" by 'pataphysics is symptomatic of a postmodern transition in science from a paradigm of absolutism to a paralogy of relativism. Structured as a descriptive explication, which emphasizes a theoretical perspective, this survey is divided into five chapters: the first chapter recounts the history of the conflict between science and poetry ; the second chapter examines the avant-garde pseudo-science of 'pataphysics itself ; and finally, the last three chapters discuss the influence of 'pataphysics upon the poetics of its subsequent successors . While my thesis focuses upon theories of textual poetics rather than poetry itself , my thesis does nevertheless strive to be as conceptually encyclopedic as 'pataphysics itself: instead of normalizing 'pataphysics within one theoretical perspective, this survey alludes intermittently to 'pataphysical enterprises that constitute exceptions to such a genealogy of Jarryites. What is at stake is the status of poetry in a world of science. How might poetry reclaim its own viable truth? How might science benefit from its own poetic irony? For the postmodern condition, such questions have already opened up a novel space for speculative imagination; hence, this survey presents itself as a kind of primer for a future of possible research.

Based on a series of lectures delivered in 1840, Thomas Carlyle’s_ On Heroes, Hero-Worship, and the Heroic in History_ considers the creation of heroes and the ways they exert heroic leadership. From the divine and prophetic to the poetic to the religious to the political, Carlyle investigates the mysterious qualities that elevate humans to cultural significance. By situating the text in the context of six essays by distinguished scholars that reevaluate both Carlyle’s work and his ideas, David Sorensen and Brent (...) Kinser argue that Carlyle's concept of heroism stresses the hero’s spiritual dimension. In Carlyle’s engagement with various heroic personalities, he dislodges religiosity from religion, myth from history, and truth from “quackery” as he describes the wondrous ways in which these “flowing light-fountains” unlock the heroic potential of ordinary human beings.

As computers became multi-component systems in the 1950s, handling the speed differentials efficiently was identified as a major challenge. The desire for better understanding and control of ‘concurrency’ spread into hardware, software, and formalism. This paper examines the way in which the problem emerged and was handled across various computing cultures from 1955 to 1985. In the machinic culture of the late 1950s, system programs called ‘monitors’ were used for directly managing synchronisation. Attempts to reframe synchronisation in the subsequent algorithmic (...) culture pushed the problem to a higher level of abstraction; Dijkstra’s semaphores were a reaction to the algorithms’ complexity. Towards the end of the 1960s, the culture of ‘structured programming’ created a milieu in which Dijkstra, Hoare, and Brinch Hansen (among others) aimed for a concurrency primitive which embodied the new view of programming. Via conditional critical regions and Dijkstra’s ‘secretaries’, the co-produced ‘monitor’ appeared to provide the desired encapsulation. The construct received embodiment in a few programming languages; this paper ends by considering Modula and Concurrent Pascal. (shrink)

This article attempts to explore some current theoretical problems within the field of postcolonial studies. In particular, I address Ato Quayson's recent complaint that postcolonial theorists generally have failed to ‘provide a persuasive account of literature and history simultaneously’, a problem which I link to what I see as the field's theoretical obsession with the concept of ‘representation’; I argue that the field's disciplinary ambition to represent, authoritatively, the postcolonial per se necessarily but also problematically circumscribes and limits its relation (...) to discourses of historical representation and literary representation. On an aesthetic level, this problematic is expressed through postcolonial studies’ troubled relationship with literary realism as an aesthetic form. In a wider perspective, I connect the field's disparagement of literary realism with Lazarus's notion of the ‘postcolonial unconscious’, i.e. postcolonial studies’ failure to grasp and address some of the deeper global-political contradictions.

Creationists believe that C. K. Chesterton created Father Brown in his detective stories. Since creating implies a creation, Father Brown exists. Atheists object that the same reasoning could prove the existence of God. But creationists such as Jonathan Schaffer insist atheists do believe that God exists. Serious metaphysics rarely concerns existence. The disagreement between the theist and the atheist is about the nature of God, not His existence. Schaffer underestimates the religious imagination. There could be a religion that explicitly regarded (...) God as a fictional character. The tenets of this, presently hypothetical, religion are developed in a dialogue. (shrink)

I examine two challenges that collaborative research raises for science. First, collaborative research threatens the motivation of scientists. As a result, I argue, collaborative research may have adverse effects on what sorts of things scientists can effectively investigate. Second, collaborative research makes it more difficult to hold scientists accountable. I argue that the authors of multi-authored articles are aptly described as plural subjects, corporate bodies that are more than the sum of the individuals involved. Though journal editors do not currently (...) conceive of the authors of multi-authored articles this way, this conception provides us with the conceptual resources to make sense of how collaborating scientists behave.Keywords: Collaborative research; Authorship; Multi-authored articles; Responsibility; Reward system; Plural subject.

Ockham's razor is popularly phrased as a prohibition against multiplying entities beyond necessity. This prohibition should extend to the receptacle for these entities. To state my thesis more positively and precisely, both qualitative and quantitative parsimony apply to space, time, and possibility. All other things equal, we ought to prefer a hypothesis that postulates less space. Smaller is better. Admittedly, scientists are ambivalent about economizing on the void. They praise simplicity. Yet astronomers have a history of helping themselves to as (...) much empty space as they wish—staggering common sense with the vastness of the universe. This largesse is abetted by an aesthetic bias for sublime hypotheses. Whereas abductions based on beauty converge with parsimony, abductions based on the sublime diverge from parsimony. Awe stifles our inner accountant. Both types of abduction are popular. Both are dubious because we lack independent assurance that the universe is beautiful or sublime. The analogy between space and time supports an extension of parsimony to time. Uniformitarian geologists regarded time as a free resource. However, geologists and cosmologists must justify their postulation of an immense past. Possibility follows suit. Contrary to David Lewis, possible worlds should be minimized. Parsimony about possibilities provides a rationale for parsimony about absences. Absences are possibilities that are not actual. So proliferation of absences entails proliferation of possibilities. We should admit only those absences which do explanatory work. (shrink)

In the twentieth century, philosophers tackled many of the philosophical problems of previous generations by dissolving them--attacking them as linguistic illusions and showing that the problems, when closely inspected, were not problems at all. Roy A. Sorensen takes the most important and interesting examples from one hundred years of analytic philosophy to consolidate a different theory of dissolution. Pseudo-Problems offers a fascinating alternative history of twentieth century analytic philosophy. It seeks to outline a unified account of dissolution that can consolidate (...) the piecemeal insights of analytic philosophers. An accessible account of questionable questions, the book represents an important contribution to the debates about creativity and problem solving. (shrink)

Traditionally the domain of scientists, the history of science became an independent field of inquiry only in the twentieth century and mostly after the Second World War. This process of emancipation was accompanied by a historiographical departure from previous, 'scientistic' practices, a transformation often attributed to influences from sociology, philosophy and history. Similarly, the liberal humanists who controlled the Cambridge History of Science Committee after 1945 emphasized that their contribution lay in the special expertise they, as trained historians, brought to (...) the venture. However, the scientists who had founded the Committee in the 1930s had already advocated a sophisticated contextual approach: innovation in the history of science thus clearly came also from within the ranks of scientists who practised in the field. Moreover, unlike their scientist predecessors on the Cambridge Committee, the liberal humanists supported a positivistic protocol that has since been criticized for its failure to properly contextualize early modern science. Lastly, while celebrating the rise of modern science as an international achievement, the liberal humanists also emphasized the peculiar Englishness of the phenomenon. In this respect, too, their outlook had much in common with the practices from which they attempted to distance their project. (shrink)
