Used for everything from geographic evaluation to secret spy missions, aerial photography has a rich and storied history, ably recounted here in Photography and Flight. Aerial photography is marked by its dependency on technological developments in both photography and aerospace, and the authors chart the history of this photography as it tracked the evolution of these technologies. Beginning with early images taken from hot-air balloons, fixed platforms, and subsequent handheld camera technology, Denis Cosgrove and William Fox then explain (...) how military reconnaissance and governmental projects were instrumental in catalyzing these and other innovations in the field. They examine pivotal historical moments in which aerial photography began to establish itself as essential tool, such as in World War II military strategies, high-altitude photography taken from postwar rockets and aircraft, and the use of aerial photography during the cold war and the Cuban Missile Crisis. The book also explores the advancement of geographic scholarship through aerial photography, ranging from military excursions into Antarctica to the images of the curvature of the earth taken during the Apollo space missions. While digital technology and remote sensing have changed the landscape of photography, Photography and Flight argues that they have not diminished the significance of aerial photography in providing images of the earth. Rather, new technologies and resulting innovations such as Google Earth have enabled the mass democratization of access to such information. Photography and Flight ultimately reveals how the camera lens from far away continues to unearth telling details about the land and those who live upon it. (shrink)

The tension between beauty and technology is evinced in the modern distinction within technē itself between technology and “fine art.” Yet while beauty,as Kant observes, is never a means to an end, neither is it an “end in itself.” Beauty points beyond itself while refusing subordination to human interests. Both its noninstrumentality and its self-transcending character I trace to the intrinsic necessity of the beautiful, which is essentially impersonal while paradoxically being an object of love. I suggest that we conceive (...) of beauty as an “anonymous voice,” and I relate the latter to Heidegger’s critique of modern technology as a projection upon nature of “resource being.” I conclude that technology can be creative rather than destructive of beauty when it lets natural ends, which are inescapably in conflict with one another, transcend themselves through self-sacrifice.

According to Aristotelian essentialism, the nature of an organism is constituted of a particular goal-directed disposition to produce an organism typical of its kind. This paper argues—against the prevailing orthodoxy—that essentialism of this sort is indispensable to evolutionary biology. The most powerful anti-essentialist arguments purport to show that the natures of organisms play no explanatory role in modern synthesis biology. I argue that recent evolutionary developmental biology provides compelling evidence to the contrary. Developmental biology shows that one must appeal to (...) the capacities of organisms to explain what makes adaptive evolution adaptive. Moreover, the specific capacities in question are precisely those that, according to Aristotle, constitute the nature of an organism.

There are two general approaches to characterising biological functions. One originates with Cummins. According to this approach, the function of a part of a system is just its causal contribution to some specified activity of the system. Call this the ‘C-function’ concept. The other approach ties the function of a trait to some aspect of its evolutionary significance. Call this the ‘E-function’ concept. According to the latter view, a trait's function is determined by the forces of natural selection. The C-function (...) and E-function concepts are clearly quite different, but there is an important relation between them which heretofore has gone unnoticed. The purpose of this paper is to outline that relation.This is not the first paper to discuss the relation of C-function and E-function. Previous attempts all follow either one of two strategies. The first proposes that the two concepts are ‘unified.’ The other proposes that they are radically distinct and apply to wholly different fields within biology. (shrink)

We distinguish dynamical and statistical interpretations of evolutionary theory. We argue that only the statistical interpretation preserves the presumed relation between natural selection and drift. On these grounds we claim that the dynamical conception of evolutionary theory as a theory of forces is mistaken. Selection and drift are not forces. Nor do selection and drift explanations appeal to the (sub-population-level) causes of population level change. Instead they explain by appeal to the statistical structure of populations. We briefly discuss the implications (...) of the statistical interpretation of selection for various debates within the philosophy of biologythe `explananda of selection' debate and the `units of selection' debate.

In 1908, three years after Einstein first published his special theory of relativity, the mathematician Hermann Minkowski introduced his four-dimensional “spacetime” interpretation of the theory. Einstein initially dismissed Minkowski’s theory, remarking that “since the mathematicians have invaded the theory of relativity I do not understand it myself anymore.” Yet Minkowski’s theory soon found wide acceptance among physicists, including eventually Einstein himself, whose conversion to Minkowski’s way of thinking was engendered by the realization that he could profitably employ it for the (...) formulation of his new theory of gravity. The validity of Minkowski’s mathematical “merging” of space and time has rarely been questioned by either physicists or philosophers since Einstein incorporated it into his theory of gravity. Physicists often employ Minkowski spacetime with little regard to the whether it provides a true account of the physical world as opposed to a useful mathematical tool in the theory of relativity. Philosophers sometimes treat the philosophy of space and time as if it were a mere appendix to Minkowski’s theory. In this critical study, Joseph Cosgrove subjects the concept of spacetime to a comprehensive examination and concludes that Einstein’s initial assessment of Minkowksi was essentially correct.

Over the past fifteen years there has been a considerable amount of debate concerning what theoretical population dynamic models tell us about the nature of natural selection and drift. On the causal interpretation, these models describe the causes of population change. On the statistical interpretation, the models of population dynamics models specify statistical parameters that explain, predict, and quantify changes in population structure, without identifying the causes of those changes. Selection and drift are part of a statistical description of population (...) change; they are not discrete, apportionable causes. Our objective here is to provide a definitive statement of the statistical position, so as to allay some confusions in the current literature. We outline four commitments that are central to statisticalism. They are: 1. Natural Selection is a higher order effect; 2. Trait fitness is primitive; 3. Modern Synthesis (MS)-models are substrate neutral; 4. MS-selection and drift are model-relative. (shrink)

The profession of medicine is predicated upon an ethical mandate: first do no harm. However, critics charge that the medical profession’s culture and its public health mission are being undermined by the pharmaceutical industry’s wide-ranging influence. In this article, we analyze how drug firms influence psychiatric taxonomy and treatment guidelines such that these resources may serve commercial rather than public health interests. Moving beyond a conflict-ofinterest model, we use the conceptual and normative framework of institutional corruption to examine how organized (...) psychiatry’s dependence on drug firms has distorted science. We suggest that academic-industry relationships have led to the corruption of the evidence base upon which accurate diagnosis and sound treatment depend. We describe the current dependency corruption and argue that transparency alone is not a solution — and sometimes even produces iatrogenic effects. Furthermore, we argue that the corruption of the evidence base for diagnostic and practice guidelines renders obsolete the traditional informed consent process, and we offer suggestions for reforming this process.

There are two competing interpretations of the modern synthesis theory of evolution: the dynamical (also know as ‘traditional’) and the statistical. The dynamical interpretation maintains that explanations offered under the auspices of the modern synthesis theory articulate the causes of evolution. It interprets selection and drift as causes of population change. The statistical interpretation holds that modern synthesis explanations merely cite the statistical structure of populations. This paper offers a defense of statisticalism. It argues that a change in trait frequencies (...) in a population can be attributed only to selection or drift against the background of a particular statistical description of the population. The traditionalist supposition that selection and drift are description‐independent causes of population change leads the dynamical interpretation into a dilemma: it must face a contradiction or accept the loss of explanatory power.

The possibility that industry is exerting an undue influence on the culture of medicine has profound implications for the profession's public health mission. Policy analysts, investigative journalists, researchers, and clinicians have questioned whether academic-industry relationships have had a corrupting effect on evidence-based medicine. Psychiatry has been at the heart of this epistemic and ethical crisis in medicine. This article examines how commercial entities, such as pharmaceutical companies, influence psychiatric taxonomy and treatment guidelines. Using the conceptual framework of institutional corruption, we (...) show that organized psychiatry's dependence on drug firms has led to a distortion of science. We describe the current dependency corruption and argue that transparency alone is not a solution. We conclude by taking the position that the corruption of the evidence base in diagnostic and practice guidelines has compromised the informed consent process, and we suggest strategies to address this problem.

The concept of the environment appears to be indispensably involved in adaptive explanation. Quite what its role is, however, is a matter of some dispute. The environment is customarily viewed as the dual of the organism; a wholly external, discrete, autonomous cause of evolution. On this view, the external environment is the principal cause of the adaptedness of form, and the determinant of what it is to be an adaptation. I argue that this conception of the environment neither adequately explains (...) nor individuates evolutionary adaptations. Instead, adaptation, properly construed, is an evolutionary response to affordances. The environment, traditionally construed, underdetermines an organism’s affordances. Instead, I argue that the environment takes its place in evolutionary models not as a discrete causal entity, but as an abstraction. (shrink)

In evolutionary biology changes in population structure are explained by citing trait fitness distribution. I distinguish three interpretations of fitness explanations—the Two‐Factor Model, the Single‐Factor Model, and the Statistical Interpretation—and argue for the last of these. These interpretations differ in their degrees of causal commitment. The first two hold that trait fitness distribution causes population change. Trait fitness explanations, according to these interpretations, are causal explanations. The last maintains that trait fitness distribution correlates with population change but does not cause (...) it. My defense of the Statistical Interpretation relies on a distinctive feature of causation. Causes conform to the Sure Thing Principle. Trait fitness distributions, I argue, do not. *Received July 2009; revised October 2009. †To contact the author, please write to: Department of Philosophy/Institute for the History, Philosophy of Science and Technology, University of Toronto, Victoria College, 91 Charles Street West, Toronto, ON M5S 1K7, Canada; e‐mail: denis[email protected].

Researchers, investigative journalists, community physicians, ethicists, and policy makers have voiced strong concerns about the integrity of medicine. Specifically, questions have been raised about the ways in which financial conflicts of interest (FCOI) in the biomedical field may be compromising the integrity of the scientific research process and thus compromising patient care by disseminating imbalanced or even inaccurate information (Angell 2004). Indeed, many of us are no longer surprised when we read about settlements made by pharmaceutical companies—some totaling hundreds of (...) millions of dollars—for withholding information on adverse side effects, overstating the efficacy of medications, or for aggressive ..

The author of this paper discusses why the issue of financial conflicts of interest in psychiatry has important public health implications for women and why FCOI complicate the informed consent process. For example, when psychiatric diagnostic and treatment guidelines are unduly influenced by industry, informed consent becomes a critical issue, because women may be assigned diagnostic labels that are not valid and may also be receiving imbalanced or even inaccurate information about their mental health treatment options. However, mere disclosure of (...) industry relationships is an insufficient solution. Following Ells, the author offers a more robust account of autonomy, inspired by Foucault, to strengthen informed consent practices. In addition to addressing power relations, this Foucauldian account of autonomy emphasizes the relational and dialogical aspect of the physician–patient relationship. (shrink)

Plant cells are caged within a distended polymeric network (the cell wall), which enlarges by a process of stress relaxation and slippage (creep) of the polysaccharides that make up the load‐bearing network of the wall. Protein mediators of wall creep have recently been isolated and characterized. These proteins, called expansins, appear to disrupt the noncovalent adhesion of matrix polysaccharides to cellulose microfibrils, thereby permitting turgor‐driven wall enlargement. Expansin activity is specifically expressed in the growing tissues of dicotyledons and monocotyledons. Sequence (...) analysis of cDNAs indicates that expansins are novel proteins, without previously known functional motifs. Comparison of expansin cDNAs from cucumber, pea, Arabidopsis and rice shows that the proteins are highly conserved in size and amino acid sequence. Phylogenetic analysis of expansin sequences suggests that this multigene family diverged before the evolution of angiosperms. Speculation is presented about the role of this gene family in plant development and evolution. (shrink)

According to a prominent view of evolutionary theory, natural selection and the processes of development compete for explanatory relevance. Natural selection theory explains the evolution of biological form insofar as it is adaptive. Development is relevant to the explanation of form only insofar as it constrains the adaptation-promoting effects of selection. I argue that this view of evolutionary theory is erroneous. I outline an alternative, according to which natural selection explains adaptive evolution by appeal to the statistical structure of populations, (...) and development explains the causes of adaptive evolution at the level of individuals. Only together can a statistical theory of selection and a mechanical theory of development explain why populations of organisms comprise individuals that are adapted to their conditions of existence.

This essay is a contribution to the historical phenomenology of science, taking as its point of departure Husserl’s later philosophy of science and Jacob Klein’s seminal work on the emergence of the symbolic conception of number in European mathematics during the late sixteenth and seventeenth centuries. Sinceneither Husserl nor Klein applied their ideas to actual theories of modern mathematical physics, this essay attempts to do so through a case study of the conceptof “spacetime.” In §1, I sketch Klein’s account of (...) the emergence of the symbolic conception of number, beginning with Vieta in the late sixteenth century. In §2,through a series of historical illustrations, I show how the principal impediment to assimilating the new symbolic algebra to mathematical physics, namely, thedimensionless character of symbolic number, is overcome via the translation of the traditional language of ratio and proportion into the symbolic language of equations. In §§3–4, I critically examine the concept of “Minkowski spacetime,” specifically, the purported analogy between the Pythagorean distance formula and the Minkowski “spacetime interval.” Finally, in §5, I address the question of whether the concept of Minkowski spacetime is, as generally assumed, indispensable to Einstein’s general theory of relativity.

Psychological individualism is motivated by two taxonomic principles: (i) that psychological states are individuated by their causal powers, and (ii) that causal powers supervene upon intrinsic physiological state. I distinguish two interpretations of individualism--the 'orthodox' and the 'alternative'--each of which is consistent with these motivating principles. I argue that the alternative interpretation is legitimately individualistic on the grounds that it accurately reflects the actual taxonomic practices of bona fide individualistic sciences. The classification of homeobox genes in developmental genetics provides an (...) illustration. When applied to the taxonomy of psychological kinds, alternative individualism has some surprising consequences. In particular, externalist taxonomies of thought are consistent with the alternative interpretation, and hence consistent with individualism. I conclude, on this basis, that the individualism/externalism dispute which has long preoccupied philosophy of psychology is an empty one. (shrink)

Of these discussions the last, from the Summa Theologiae, is the best known and is often taken as representative of Thomas’ response to Anselm. Yet it would seem, on the face of it, unsatisfying as a refutation. Gareth Matthews’ comment expresses a very widely shared reaction: "Instead of showing that Anselm’s argument is invalid, Aquinas seems content to state, without counterargument, that the alleged conclusion does not follow." To many, Thomas’ critique represents no advance beyond Gaunilo in understanding Anselm, but (...) merely reproduces Gaunilo’s objection against Proslogion III in Pro Insipiente VII, and his critique has even evoked from one of the most influential modern proponents of Anselm’s argument the remark "This is not very perceptive, is it?" Such an attitude has, as one might expect, hardly been modified by the satisfaction with which Thomists often regard Thomas’ rebuttal while ignoring both the logic of the argument and the details of Thomas’ reply to it.

Simone Weil is widely recognized today as one of the profound religious thinkers of the twentieth century. Yet while her interpretation of natural science is critical to Weil's overall understanding of religious faith, her writings on science have received little attention compared with her more overtly theological writings. The present essay, which builds on Vance Morgan's Weaving the World: Simone Weil on Science, Necessity, and Love (2005), critically examines Weil's interpretation of the history of science. Weil believed that mathematical science, (...) for the ancient Pythagoreans a mystical expression of the love of God, had in the modern period degenerated into a kind of reification of method that confuses the means of representing nature with nature itself. Beginning with classical (Newtonian) science's representation of nature as a machine, and even more so with the subsequent assimilation of symbolic algebra as the principal language of mathematical physics, modern science according to Weil trades genuine insight into the order of the world for symbolic manipulation yielding mere predictive success and technological domination of nature. I show that Weil's expressed desire to revive a Pythagorean scientific approach, inspired by the "mysterious complicity" in nature between brute necessity and love, must be recast in view of the intrinsically symbolic character of modern mathematical science. I argue further that a genuinely mystical attitude toward nature is nascent within symbolic mathematical science itself. (shrink)
