Although pioneering studies using statistical methods in geographical data analysis were published in the 1930s, it was only in the 1960s that their increasing use in human geography led to a claim that a ‘quantitative revolution’ had taken place. The widespread use of quantitative methods from then on was associated with changes in both disciplinary philosophy and substantive focus. The first decades of the ‘revolution’ saw quantitative analyses focused on the search for spatial order of a geometric form within an, (...) often implicit, logical positivist framework. In the first of three reviews of the use of quantitative methods in human geography, this progress report uncovers their origin with regard to the underlying philosophy, the focus on spatial order, and the nature of the methods deployed. Subsequent reports will outline the changes in all three that occurred in later decades and will chart the contemporary situation. (shrink)

The role of imagery in encoding event-based prospective memories has yet to be fully clarified. Herein, it is argued that imagery augments a cue-to-context association that supports event-based prospective memory performance. By this account, imagery encoding not only improves prospective memory performance but also reduces interference to intention-related information that occurs outside of context. In the current study, when lure words occurred outside of the appropriate responding context, the use of imagery encoding strategies resulted in less interference when compared with (...) a standard event-based intention condition. This difference was eliminated when participants were not given a specific context to associate their intention . These results support a cue-to-context association account of how imagery operates in certain event-based prospective memory tasks. (shrink)

Bringing together the expertise of rhetoricians in English and communication as well as media studies scholars, Arguments about Animal Ethics delves into the rhetorical and discursive practices of participants in controversies over the use of nonhuman animals for meat, entertainment, fur, and vivisection. Both sides of the debate are carefully analyzed, as the contributors examine how stakeholders persuade or fail to persuade audiences about the ethics of animal rights or the value of using animals.

This study examined people’s ability to predict and postdict their performance on an event-based prospective memory task. Using nonfocal cues, one group of participants predicted their success at finding animal words and a different group predicted their ability to find words with a particular syllable in it. The authors also administered a self-report questionnaire on everyday prospective and retrospective memory failures. Based on the different strategies adopted by the two groups and correlations among the dependent variables, the authors concluded that (...) people do have a basic awareness of their prospective memory abilities, but that this awareness is far from accurate. The importance of metamemory concerning one’s prospective memory is discussed in terms of how it influences the strategies that people might choose for actually completing their various everyday intentions.

In lieu of an abstract, here is a brief excerpt of the content:Pragmatist Aesthetics and New Visions of the Contemporary Art Museum:The Tate Modern and the Baltic Centre for Contemporary ArtAngela Marsh (bio)John Dewey mandated the repositioning of our experience of art within the realm of the everyday, and recognized the importance of art objects principally with regard to how they operate within an experience as "carriers of meaning."1 In this quote from Art as Experience, Dewey illustrates the segue (...) between art and the perceiver, and his belief that within the profound art experience, lived dichotomies are healed:In art as an experience, actuality and possibility or ideality, the new and the old, objective material and personal response, the individual and the universal, surface and depth, sense and meaning, are integrated in an experience in which they are all transfigured from the significance that belongs to them when isolated in reflection.2Although the ephemeral nature of Dewey's definition of art-as-experience — hinged upon immediacy and the subjective heuristics of the perceiver — may seem difficult to capture and apply, the practicality of the concept, Richard Shusterman argues, lies in its "transformative potential," as a way to reconceive the place of art and its function in our world:Defining art as experience, I argue, also has value in widening the realmof art by challenging the rigid definition between art and action that is supported by definitions that define art as mimesis, poiesis, or the narrow practice as defined by the institutional art world. In other words, I argue that Dewey's definition of art as experience has a very fruitful transformational potential.3By defining art as experience, Dewey also sought to dissolve the binary structures of aesthetic rifts: art and life, high art and low art, body and mind, subject and object, self and world, emphasizing the holistic action in our engagement with art.4 But according to Dewey, the divisor of art from life and thus to blame for the aesthetic barrenness of our lived reality is the museum institution, as Shusterman describes: [End Page 91]The compartmentalization and spiritualization of art as an elevated "separate realm" set "upon a far-off pedestal," divorced from the materials and aims of other human effort, has removed art from the lives of most of us, and thus impoverished the aesthetic quality of our lives.(PA, 19)However, we must keep in mind that Art as Experience was published in 1934. Today, new approaches towards encounter and engagement within public museums are taking form and gaining momentum, with unprecedented directorial visions and mandates designed to nurture and make accessible art-based experiences among diverse audiences — where art and life can meet via multiple approaches. Theoretical synchronicities between pragmatist approaches to aesthetics and fruitful museum experiences can be suggested upon consideration of various innovative programs and approaches initiated at the Tate Modern in London and the Baltic Center for Contemporary Art in Gateshead. The overwhelming success of both venues could signify a reengagement of the general public with contemporary art, fed by "democratic," participatory approaches to exhibiting and programming art that make the museum more accessible to the various mixed publics it serves. In light of these new museological developments, Dewey's polemic oppositions between his conceptualizations of the museum experience and "art-as-experience" should be reexamined and possibly redefined.Dewey was entirely opposed to the concept of "art for art's sake." By exonerating art of any functional value — deeming it "fine" — art was elevated to a position separate from life, and thus rendered impotent to effect a lived aesthetic experience (which is how, Dewey would argue, the arts function most powerfully — as the purveyors of heightened experience). As Shusterman describes:The underlying motive for such attempts to purify art from any functionality was not to denigrate it as worthlessly useless, but to place its worth apart from and above the realm of instrumental value...and this freedom from use would be its defining and ennobling feature.(PA, 9)Dewey (and Shusterman) thus maintained that the very power construct that put the "fine" in art did so by removing the aspect of function from it. As previously stated, Dewey blamed museum institutions for removing art from its... (shrink)

Marsh borrows Richard McKeon's methodological notion of the "problematic" approach to intellectual history.

"All art should become science and all science art; poetry and philosophy should be made one." Friedrich Schlegel's words perfectly capture the project of the German Romantics, who believed that the aesthetic approaches of art and literature could reveal patterns and meaning in nature that couldn't be uncovered through rationalistic philosophy and science alone. In this wide-ranging work, Robert J. Richards shows how the Romantic conception of the world influenced (and was influenced by) both the lives of the people (...) who held it and the development of nineteenth-century science. Integrating Romantic literature, science, and philosophy with an intimate knowledge of the individuals involved—from Goethe and the brothers Schlegel to Humboldt and Friedrich and Caroline Schelling—Richards demonstrates how their tempestuous lives shaped their ideas as profoundly as their intellectual and cultural heritage. He focuses especially on how Romantic concepts of the self, as well as aesthetic and moral considerations—all tempered by personal relationships—altered scientific representations of nature. Although historians have long considered Romanticism at best a minor tributary to scientific thought, Richards moves it to the center of the main currents of nineteenth-century biology, culminating in the conception of nature that underlies Darwin's evolutionary theory. Uniting the personal and poetic aspects of philosophy and science in a way that the German Romantics themselves would have honored, The Romantic Conception of Life alters how we look at Romanticism and nineteenth-century biology.

This is an excellent article, probably the best there is in defence of prohibiting the sale of organs, and it deserves a much fuller discussion of detail than there is space for here.1 My concerns, however, are with generalities rather than detail. Although some such argument might justify prohibition of organ selling in particular places and at particular times, it is difficult to see how it could support the kind of general, universal policy currently accepted by most advocates of prohibition.Whenever (...) the subject of organ selling is discussed, it is useful to keep in mind the natural history of the debate. Prohibition was instituted by most governments and professional bodies just about as quickly as possible after it was discovered that payment for kidneys was going on, and was a direct response to feelings of moral outrage. It all happened without time for debate. It was only later, as challenges appeared, that justifications began to be produced; and when they did they followed a pattern long familiar to philosophers, and more recently recognised by moral psychologists, of determined efforts to find a justification for the initial intuition that organ selling must be wrong. New arguments kept appearing in the cause as earlier attempts were shown to fail, and many were so weak that they could not have seemed plausible unless their advocates had already been committed to their conclusion. This does not mean, of course, that a good justification could never be produced. It does, however, suggest a widespread feeling that organ selling must be intrinsically …. (shrink)

When Charles Darwin (1859, 482) wrote in the Origin of Species that he looked to the “young and rising naturalists” to heed the message of his book, he likely had in mind individuals like Ernst Haeckel (1834-1919), who responded warmly to the invitation (Haeckel, 1862, 1: 231-32n). Haeckel became part of the vanguard of young scientists who plowed through the yielding turf to plant the seed of Darwinism deep into the intellectual soil of Germany. As Haeckel would later observe, the (...) seed flourished in extremely favorable ground. The German mind, he would write (1868), was predisposed to adopt the new theory. The great philosopher Immanuel Kant (1724- 1804), for instance, was on the verge of accepting a transmutational view in his Third Critique (1790; 1957, 538-39), though he stepped gingerly back from the temptation. Johann Wolfgang von Goethe (1749-1832), about the same time, dallied with transmutational ideas, at least Haeckel would convince Darwin that the Englishman had an illustrious predecessor. Jean-Baptiste de Lamarck’s (1744-1829) conceptions had taken hold among several major German thinkers in the first few decades of the nineteenth century in a way they had not in England and France. Among those ready to declare themselves for the new dispensation was Rudolf Virchow (1821-1902), Haeckel’s teacher at Würzburg—though, this very political scientist would prove Haeckel’s nemesis later in the century. So Haeckel’s estimate of the ripeness of German thought was not off the mark. Darwinism took hold in the newly unified land, though not without some struggle; but at last it became the dominant view in the biological sciences. But with its success did it foster the malign racist ideology that transfixed Adolf Hitler (1889-1945)? (shrink)

In 1914, James Leuba, a psychologist at Bryn Mawr, conducted several surveys of scientists and college students regarding their religious beliefs, publishing his findings in a 1916 book titled The Belief in God and Immortality. Among scientists generally, 41.8 percent indicated they were believers in a personal God (defined as a being to whom one could pray, expecting a response), whereas 41.5 percent expressed disbelief in such a God and 16.7 percent declared themselves to be agnostic. Among elite scientists (those (...) with an asterisk by their names in James McKean Cattell's American Men of Science), the percentage of believers was lower, at 31.6 percent. Among elite biologists, the subset who believed in God was even smaller—16.9 percent. In 1996 and 1998, Edward Larson and Larry Witham replicated Leuba's study, publishing their findings in the April 23, 1997, and July 23, 1998, issues of Nature. Their surveys revealed that of all scientists questioned, 39.3 percent professed belief in a personal God, about the same as in the 1914 study. However, among elite scientists—now defined as members of the National Academy of Sciences—the proportion who were believers had plummeted to 7 percent, with biologists showing the least religious conviction at 5.5 percent. In the general population of the United States, some 86 percent profess belief in the existence of a personal God, according to a 1999 Gallup poll. These figures dramatically indicate the great no-mans land separating the religious convictions of ordinary citizens from those of the scientific community, especially its leading members. This dissensus has fueled many of the bitter battles recently fought over evolution and stem cells and has ignited explosive devices laid along several political byways. (shrink)

Though Darwin had formulated his theory of evolution by natural selection by early fall of 1837, he did not publish it until 1859 in the Origin ofSpecies. Darwin thus delayed publicly revealing his theory for some twenty years, Why did he wait so long'? Initially this may not seem an important or interesting question, but many historians have so regarded it, They have developed a variety of historiographically different explanations. This essay considers these several explanations, though with a larger purpose (...) in mind: to suggest what makes for interesting problems in history of science and what kinds of historiographic models will best handle them..

Logical psychologism is the position that logic is a special branch of psychology, that logical laws are descriptíons of experience to be arrived at through observation, and are a posteriori.The accepted arguments against logical psychologism are effective only when directed against this extreme version. However, the clauses in the above characterization are independent and ambiguous, and may be considered separately. This separation permits a reconsideration of less extreme attempts to tie logic to psychology, such as those defended by Mill and (...) Boole. It also provides the basis for a reexamination of the relationship between logic and psychology, and raises the possibility of a deeper investigation into the nature of logic itself. (shrink)

This book is the most comprehensive, integrated explanatory account yet published of the properties of question formations and their variation across languages. It makes an important contribution to the current debate over whether syntax should be understood derivationally, arguing that the best model of language is one in which sentences are constructed in a series of operations that precede or follow each other in time. The central problem it addresses is the nature of the difference between languages in which all (...) wh-words move overtly to a clause-initial position ; languages in which one wh-phrase moves per clause but all others remain in situ ; and languages in which there is no overt movement at all. Professor Richards focuses on the nature of syntactic movement in order to see what this reveals about the syntactic derivation. He considers the nature of interactions between movement operations and investigates the behaviour of multiple overt wh-movement, scrambling, cliticization, and object shift. His general conclusions about the relationship between movement and multiple specifiers follow straightforwardly from basic principles of Shortest Move and Shortest Attract. He develops a PF-imposed well-formedness condition on movement chains, which allows for the development of theories of anti-agreement, the that-trace effect, and the conditions on participial agreement in Romance, among other phenomena. He defends the claim that well-formed dependencies can improve the status of ill-formed dependencies created later in the derivation, illustrating the explanatory power, under certain structural conditions, of his Principle of Minimal Compliance. He uses data on the locality of wh-movement to argue that the Principle of Minimal Compliance is responsible for a number of the apparent distinctions between overt and covert movement. This book will interest syntacticians at graduate level and above as well as linguistic theorists concerned with the syntax-semantics interface. (shrink)

Historians are now generally agreed that the Darwinian recognition and institutionalization of the polygenist position was more than merely nominal.194 Wallace, Vogt, and Huxley had led the way, and we may add Galton (1869) to the list of those leading Darwinians who incorporated a good deal of polygenist thinking into their interpretions of human history and racial differences.195 Eventually “Mr. Darwin himself,” as Hunt had suggested he might, consolidated the Darwinian endorsement of many features of polygenism. Darwin's Descent of Man (...) was published in the same year that the Anthropological Institute was founded, and it was no coincidence that it was broadly congruent with Knoxian/ Anthropological race science. Recent scholarship has stressed the derivative character of the Descent, and Darwin's views on race were clearly influenced by the earlier interpretations of the abovecited Darwinians.196However, although the Descent was written in the light of the anthropological struggles of the 1860s, it is essential to acknowledge its origins in Darwin's notebooks of the late 1830s and early 1840s. A good deal of the congruence between Darwinian and Knoxian conceptions of race may be traced back to these early notebook constructions. As these document, Darwin, like Knox, brought to his very earliest conceptions of human evolution a “commitment to the idea of human races as discrete biological units with distinct moral and mental traits.”197 The young Darwin had been concerned with the same sorts of questions on racial biological and cultural differences that preoccupied Knox around the same time, and he was committed to as ruthless a naturalism. Apart from their individual and independent debts to Quetelet's “moral statistics,” both Darwin and Knox drew heavily on the general themes of struggle and adaptation in the contemporary “common context” of biological and social thought.198 Given their common context, the broad general similarities between the Knoxian laws of race antagonism and subordination and the Darwinian struggle for existence between races need occasion no strained historical explanation of direct influence.199Nevertheless, in more explicit ways, the Descent does show the conflation of Knoxian/Anthropological and Darwinian racial views, and Darwin located his discussion of these issues squarely within the dispute “of late years” between polygenists and monogenists.200 His mature views on race were shaped by the contemporaneous confrontations and negotiations between the Darwinians and the Anthropologicals. It is within this context that the minor historical puzzle of Darwin's failure to acknowledge Knox's “generic descent” may be explained. Apart from the difficulties of integration and interpretation of his scattered theoretical writings, Knox, through his adoption by Hunt and the Anthropologicals, became identified with anti-Darwinism and therefore with antievolutionism.201 Moreover, Knox, the disreputable and marginal “savage radical” and lately resurrected and equally unsavory “Anthropological,” was hardly an acceptable “precursor.” Yet, paradoxically, it was via the antithetical medium of the Anthropological platform that Knox's race science made an indirect and unacknowledged, but lasting, impact on the Darwinian anthropological model.In the Descent, Darwin argued that racial traits arose very early in the prehistory of man, were not biologically adaptive, and were therefore relatively fixed in character. By viewing race formation as a distant and closed episode of human history, Darwin endorsed the Knoxian categories of race as fixed and unalterable types. Although he thought it irrelevant whether human races were called species or subspecies, he conceded more to the Knoxian view than Huxley by granting that a naturalist confronted for the first time by specimens of Negro and European man “might feel himself fully justified in ranking the races of man as distinct species.”202 Consistent with the Knoxian interpretation, struggle, competition, and survival occurred between racial units rather than between individuals and, in Darwin's view, accounted for the superiority of the Anglo-Saxon and the inevitable triumph of the more intellectual and moral races over the lower and more degraded ones.Darwin was as insistent as Knox on the biological basis of intellectual and moral differences, and, through his tendency to reduce social and cultural differences to biology, he maintained the essential Knoxian/Anthropological link between race and culture.203 For above all, the Descent did much more than offer a naturalistic explanation of human evolution: it proffered social interpretation, justification, and prescription, and its timely appearance gave a powerful boost to the “moralizing naturalism” of Huxley and Galton, and to Spencer's “Social Darwinism.”204 We may draw a straight line from Knox's “moral anatomy,” through Hunt's “anthropology,” and on to “Social Darwinism” and the “social surgeons” of the eugenics movement.The Darwinians did not, of course, we their tendency to naturalize existing economic and social relations to Knox or Hunt and the Anthropologicals—they were simply reflecting the same general intellectual trend that had affected Knox and the Anthropologicals as well. And in the larger context, the forces that had created a climate receptive to Knox's racism had intensified: in the seventies, the need to justify white imperialism and class and racial inequalities was greater than ever. Scientific racism no longer appeared an aberration but the very essence of the scientific study of man, taking on a newfound respectability in the “new” evolutionary anthropology. But in more specific ways, through the struggle between the Darwinians and Anthropologicals for scientific and ideological hegemony, Knox's “moral anatomy” was institutionalized and perpetuated in late Victorian scientific racism. In the process, the delicate balance that Knox had maintained between his radicalism and his racism was outweighed by conservative institutional and social needs, and his “moral anatomy” was retooled — first by Hunt, and then by the Darwinians — to fit those needs.

Social interactions and personal relationships are essential for a minimally good life, and rights to such things – social rights – have been increasingly acknowledged in the literature. The question as to what extent social rights are feasible – and properly qualify as rights – however, remains. Can individuals reliably provide each other with love and friendship after trying, for instance? At first glance, this claim seems counterintuitive. This paper argues, contrary to our pre-theoretic intuitions, that individuals can reliably provide (...) each other with such relationships, rendering even “thick” social rights feasible. This conclusion challenges the assumption that such things cannot be reliably provided after trying, and suggests that a surprisingly wide class of social rights are feasible. Claiming relationships characterised by love or friendship as a matter of justice, therefore, is possible, and our theories of justice should appropriately widen to accommodate this fact where appropriate.

In a series of articles and in a recent book, What Darwin Got Wrong, Jerry Fodor has objected to Darwin’s principle of natural selection on the grounds that it assumes nature has intentions.1 Despite the near universal rejection of Fodor’s argument by biologists and philosophers of biology (myself included),2 I now believe he was almost right. I will show this through a historical examination of a principle that Darwin thought as important as natural selection, his principle of divergence. The principle (...) was designed to explain a phenomenon obvious to any observer of nature, namely, that animals and plants form a hierarchy of clusters. Theodosius Dobzhansky made this the motivating observation of his great synthesizing work, Genetics and the Origin of Species (1937): “the living world is not a single array of individuals in which any two variants are connected by a series of intergrades, but an array of more or less distinctly separate arrays, intermediates between which are absent or at least rare. . .

Global fatalities related to COVID-19 are expected to be high in 2020–2021. Developing and delivering a vaccine may be the most likely way to end the pandemic. If it were possible to shorten this development time by weeks or months, this may have a significant effect on reducing deaths. Phase II and phase III trials could take less long to conduct if they used human challenge methods—that is, deliberately infecting participants with COVID-19 following inoculation. This article analyses arguments for and (...) against such methods and provides suggested broad guidelines for regulators, researchers and ethics committees when considering these matters. It concludes that it may be possible to maintain current ethical standards yet still permit human challenge trials in a context where delay is critical. The implications are that regulators and researchers need to work together now to design robust but short trials and streamline ethics approval processes so that they are in place when applications for trials are made.

Upshot: Conversational conferences are difficult to design in a way that avoids the consequences that arise when participants are not experienced with or fully value the conversational mode of interaction. So, the designers of such conferences must experiment with ways to build a culture, use a structure, and facilitate participation that might mitigate some of these consequences. The potential of the experimental conference designed in the light of second-order cybernetics lies, in part, in the prospect of identifying and acquiring the (...) conversational abilities and appreciations necessary to support a participative-dialogic society.

Who can divine the intentions of the human heart, the motives that guide behavior? Some of the reasons for our actions lie on the surface of consciousness, whereas others are more deeply embedded in the recesses of the mind. Recovering motives and intentions is a principal job of the historian. For without some attribution of mental attitudes, actions cannot be characterized and decisions assessed. The same overt behavior, after all, might be described as “mailing a letter” or “fomenting a revolution.” (...) The recovery of intentions is crucial for the historian’s narrative. (shrink)

In late September 1838, Darwin read Malthus's Essay on Population, which left him with “a theory by which to work.”115 Yet he waited some twenty years to publish his discovery in the Origin of Species. Those interested in the fine grain of Darwin's development have been curious about this delay. One recent explanation has his hand stayed by fear of reaction to the materialist implications of linking man with animals. “Darwin sensed,” according to Howard Gruber, “that some would object to (...) seeing rudiments of human mentality in animals, while others would recoil at the idea of remnants of animality in man.”116 With this link closed, Darwin hung the materialist chain around his own neck, where it rested most uncomfortably. Stephen Gould, supporting Gruber's argument, finds evidence for this reconstruction in Darwin's M and N notebooks, whichinclude many statements showing that he espoused but feared to expose something he perceived as far more heretical than evolution itself: philosophical materialism-the postulate that matter is the stuff of all existence and that all mental and spiritual phenomena are its by-products. No notion could be more upsetting to the deepest traditions of Western thought than the statement that mind-however complex and powerful-is simply a product of brain.117The proferred hypothesis suggests, then, that Darwin was acutely sensible of the social consequences of equating men with animals and therefore mind with brian, and that he thus shied from publically revealing his views until the intellectual climate became more tolerant.The history I have examined makes this hypothesis implausible. Even if Darwin warily explored the implications of his emerging theory in his notebooks, his subsequent study of Fleming, Wells, Brougham, and Kirby should have quieted any trepidation. If these natural theologians did not flinch at seeing human reason prefigured in the mind of a worm, should Darwin have? Moreover, he recognized in his M notebook that the thesis of evolutionary continuity between men and animals did not require an explicit avowal of his conviction that brain was the agent of thought.118 And in any case, his materialism was of a rather benign sort; at least he so expressed it in an annotation in Abercrombie's Inquiries concerning the Intellectual Powers (1838): “By materialism I mean, merely the intimate connection of thought with form of brain — like kind of attraction with nature of element.”119 This belief would have held little terror for British intellectuals, who were quite familiar — some even comfortable-with Locke's anti-Cartesian argument that there was nothing contradictory in supposing God could make matter to think.120 Finally, even if the intellectual atmosphere of early nineteenth-century Britain were inhospitable to Darwin's brand of materialism, there is little reason to believe he breathed a different air at mid-century while preparing his manuscript.That Darwin should not have feared suspicions of materialism, of course, does not mean that he did not. But I think there were other, more persistent sources of anxiety that kept him from rushing to publish: namely, the several conceptual obstacles he had to overcome if his theory of evolution by natural selection were to be made scientifically acceptable. Prominent among these were the problems surrounding his changing notions of instinct.The inertia of his older ideas about instinct at first made it hard for Darwin to gauge how far the theory of natural selection might be applied to behavior. By the early 1840s he finally felt ready to meet the challenge of the natural theologians by providing a naturalistic explanation for the wonderful instincts of animals. In his “Essays” of 1842 and 1844 one sort of instinct is, however, not considered-that of neuter insects. Yet Darwin seems to have appreciated the difficulties such instincts entailed at least by 1843, when he read Kirby and Spence. He simply required time to work out a solution to a problem he initially perceived as “fatal to my whole theory.” Even while writing the “Species Book” in the summer of 1857, he was still juggling several possible solutions compatible with natural selection. It was only a short time before he actually turned to work on the Origin of Species that he appears to have settled on a single explanation for the difficulties posed by the instincts of worker bees and ants. The force of his theory of community selection snapped the last critical support of the creationist hypothesis and, conveniently enough, also fractured the generalized Lamarckian account of the evolution of behavior. These results were worth waiting for. (shrink)
