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)

What is attention? On one influential position, attention constitutively is the selection of some stimulus for coupling with a response. Wayne Wu has proposed a master argument for this position that relies on the claim that cognitive science commits to an empirical sufficient condition (ESC), according to which, if a subject S perceptually selects (or response-couples) X to guide performance of some experimental task T, she therein attends to X. In this paper I show that this claim about cognitive science (...) is false. Cognitive science allows for inattentive selection-for-task, or inattentive response-coupling. This means that Wu’s account is without independent support. (shrink)

Conscious Agency is a major driver of evolution. Artificial Selection (i.e. Conscious Selection by human breeders) was the foil against which Charles Darwin defined Natural Selection. In later work, he extended Artificial Selection to other species. That ability for social (e.g. sexual) selection must have evolved. Jablonka and Ginsburg identify markers of conscious agency, such as Unlimited Associative Learning (UAL), and show that it must have existed at the time of the Cambrian Explosion. To their insights, my commentary argues that (...) the harnessing of stochasticity was also involved in the evolution of the faculty of choice in organisms. (shrink)

The Modern Synthesis has dominated biology for 80 years. It was formulated in 1942, a decade before the major achievements of molecular biology, including the Double Helix and the Central Dogma. When first formulated in the 1950s these discoveries and concepts seemed initially to completely justify the central genetic assumptions of the Modern Synthesis. The Double Helix provided the basis for highly accurate DNA replication, while the Central Dogma was viewed as supporting the Weismann Barrier, so excluding the inheritance of (...) acquired characteristics. This article examines the language of the Modern Synthesis and reveals that it is based on four important misinterpretations of what molecular biology had shown, so forming the basis of the four Illusions: 1. Natural Selection; 2. The Weismann Barrier; 3. The Rejection of Darwin’s Gemmules; 4. The Central Dogma. A multi-level organisation view of biology avoids these illusions through the principle of biological relativity. Molecular biology does not therefore confirm the assumptions of the Modern Synthesis.

In paradigm exercises of agency, individuals guide their activities toward some goal. A central challenge for action theory is to explain how individuals guide. This challenge is an instance of the more general problem of how to accommodate individuals and their actions in the natural world, as explained by natural science. Two dominant traditions–primitivism and the causal theory–fail to address the challenge in a satisfying way. Causal theorists appeal to causation by an intention, through a feedback mechanism, in explaining guidance. (...) Primitivists postulate primitive agential capacities in their explanations. The latter neglect to explain how primitive capacities integrate with findings from natural science. The former do not explain why some feedback mechanism’s activity amounts to the agent’s guidance. In this paper I argue that both traditions should acknowledge a capacity to guide, as actually constituted by the executive system. I argue that appeals to this empirically discovered psychological system explain how individuals guide in a way that integrates with explanations from cognitive science. Individuals’ capacity to guide is embedded in the natural world through the activity of its constituent (mechanistic) components. (shrink)

Is an appropriate causal connection to the past experience it represents a necessary condition for a mental state to qualify as an episodic memory? For some years this issue has been the subject of an intense debate between the causalist theory of episodic memory (CTM) and the simulationist theory of episodic memory (STM). This paper aims at exploring the prospects for an embodied approach to episodic memory and assessing the potential case for causalism that could be founded on it. In (...) a critical section, it argues that the empirical data to which STM appeals are both incomplete and inconclusive, and on closer examination even provide support for a proceduralist version of CTM. In a constructive section, it elaborates on the notion of a necessary causal connection in terms of particular procedural patterns acquired at encoding and operative at retrieval, grounding this move on recent empirical data about eye movements in mnemonic mental imagery.

How do individuals guide their activities towards some goal? Harry Frankfurt once identified the task of explaining guidance as the central problem in action theory. An explanation has proved to be elusive, however. In this paper, I show how we can marshal empirical research to make explanatory progress. I contend that human agents have a primitive capacity to guide visual attention, and that this capacity is actually constituted by a sub-individual psychological control-system: the executive system. I thus illustrate how we (...) can explain exercises of individual-level guidance by appeal to its sub-individual constitution. This opens up a new avenue for explicating agency. (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.walsh@utoronto.ca.

Grand philosophe, grand mathématicien, Descartes a-t-il été aussi un grand écrivain? La question est classique. A l'évidence, il existe un style cartésien, dont le Discours de la Méthode offre une sorte de bouquet, avec ses longues phrases à la construction puissante et aux savantes modulations. Ce style résulte d'une éducation littéraire que Descartes n'a en vérité jamais répudiée. De quoi cette éducation a-t-elle été faite? Quelle relation le philosophe entretient-il avec le langage? Comment passe-t-il du latin, " langue de ses (...) précepteurs ", au français, " langue de son pays "? De quel travail de la pensée la phrase cartésienne est-elle le théâtre? Ces questions n'ont rien de subsidiaire. Se pencher sur le style de Descartes, c'est s'engager dans un voyage à travers ses textes. Des notes de jeunesse jusqu'aux dernières lettres, on y rencontrera des paysages presque ignorés, où s'incarne, au plus loin des simplifications scolaires, une pensée d'une audace restée inouïe.

In recent years, there has been an increasing interest among philosophers of memory in the questions of how to characterize and to account for the temporal phenomenology of episodic memory. One prominent suggestion has been that episodic memory involves a feeling of pastness, the elaboration of which has given rise to two main approaches. On the intentionalist approach, the feeling of pastness is explained in terms of what episodic memory represents. In particular, Fernández has argued that it can be explained (...) in terms of memory representing itself as being caused by a past perceptual experience. On the metacognitive approach, which we have recently developed in, the feeling of pastness results from the monitoring and interpretation of the processing features of episodic remembering. In this paper, we show that the metacognitive approach should be preferred over the intentionalist approach. We argue that intentionalism, and Fernández’ causal self-referential view in particular, ultimately fail as accounts of the feeling of pastness. The difficulties faced by intentionalism allows us to single out three constraints that any satisfactory account of the temporal phenomenology of episodic remembering needs to meet. We conclude by arguing that the metacognitive view satisfies those constraints in a neat way, and as such, that it should be preferred over intentionalism. (shrink)

Whenever a structure with a particularly interesting computability-theoretic property is found, it is natural to ask whether similar examples can be found within well-known classes of algebraic structures, such as groups, rings, lattices, and so forth. One way to give positive answers to this question is to adapt the original proof to the new setting. However, this can be an unnecessary duplication of effort, and lacks generality. Another method is to code the original structure into a structure in the given (...) class in a way that is effective enough to preserve the property in which we are interested. In this paper, we show how to transfer a number of computability-theoretic properties from directed graphs to structures in the following classes: symmetric, irreflexive graphs; partial orderings; lattices; rings ; integral domains of arbitrary characteristic; commutative semigroups; and 2-step nilpotent groups. This allows us to show that several theorems about degree spectra of relations on computable structures, nonpreservation of computable categoricity, and degree spectra of structures remain true when we restrict our attention to structures in any of the classes on this list. The codings we present are general enough to be viewed as establishing that the theories mentioned above are computably complete in the sense that, for a wide range of computability-theoretic nonstructure type properties, if there are any examples of structures with such properties then there are such examples that are models of each of these theories.

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)

Skilled action typically requires that individuals guide their activities toward some goal. In skilled action, individuals do so excellently. We do not understand well what this capacity to guide consists in. In this paper I provide a case study of how individuals shift visual attention. Their capacity to guide visual attention toward some goal (partly) consists in an empirically discovered sub-system – the executive system. I argue that we can explain how individuals guide by appealing to the operation of this (...) sub-system. Understanding skill and skilled action thus requires appreciating the role of the executive system. (shrink)

The extensive range and depth of the twenty commentaries on my target article confirms that something has gone deeply wrong in biology. A wide range of biologists has more than met my invitation for “others to pitch in and develop or counter my arguments.” The commentaries greatly develop those arguments. Also remarkably, none raise issues I would seriously disagree with. I will focus first on the more critical comments, summarise the other comments, and then point the way forward on what (...) I view as a necessary and long-overdue transition in the foundations of biology. (shrink)

Heidegger discusses Aristotle’s concept of ‘phronêsis’ at length at crucial junctures in the development of his concept of ‘authenticity’; and there is a widely-held suspicion that that development is indebted to those discussions. The present paper examines that suspicion in the light of an apparent tension in Aristotle’s texts between understanding phronêsis as a perceptual capacity and understanding it as a deliberative capacity. Bronwyn Finnigan has argued that some influential, recent Heideggerian scholarship on this topic emphasises the perceptual and downplays (...) the deliberative, and there is evidence in Heidegger’s texts that might suggest he does too. The present paper, however, offers an alternative to this perceptually-focused reading, which I call ‘the all-things-considered judgment reading’. It understands the exercise of phronêsis, and the authenticity which Heidegger models upon it, as deliberative feats, accommodates the evidence thought to support the perceptually-focused reading, and avoids philosophical objections that the latter reading invites.

Several notions of computability-theoretic reducibility between [Formula: see text] principles have been studied. This paper contributes to the program of analyzing the behavior of versions of Ramsey’s Theorem and related principles under these notions. Among other results, we show that for each [Formula: see text], there is an instance of RT[Formula: see text] all of whose solutions have PA degree over [Formula: see text] and use this to show that König’s Lemma lies strictly between RT[Formula: see text] and RT[Formula: see (...) text] under one of these notions. We also answer two questions raised by Dorais, Dzhafarov, Hirst, Mileti, and Shafer on comparing versions of Ramsey’s Theorem and of the Thin Set Theorem with the same exponent but different numbers of colors. Still on the topic of the effect of the number of colors on the computable aspects of Ramsey-theoretic properties, we show that for each [Formula: see text], there is an [Formula: see text]-coloring [Formula: see text] of [Formula: see text] such that every [Formula: see text]-coloring of [Formula: see text] has an infinite homogeneous set that does not compute any infinite homogeneous set for [Formula: see text], and connect this result with the notion of infinite information reducibility introduced by Dzhafarov and Igusa. Next, we introduce and study a new notion that provides a uniform version of the idea of implication with respect to [Formula: see text]-models of RCA0, and related notions that allow us to count how many applications of a principle [Formula: see text] are needed to reduce another principle to [Formula: see text]. Finally, we fill in a gap in the proof of Theorem 12.2 in Cholak, Jockusch, and Slaman. (shrink)

Brentano clearly asserts, in his Vienna lectures of 1887–1888, that his descriptive psychology is an a priori or “exact” science. Since he rejects Kant's idea of a synthetic a priori, this means that the descriptive psychologist's laws are analytic. My aim in this paper is to clarify and discuss this view. I examine Brentano's epistemology in the Psychology from an Empirical Standpoint and then its later developments. I conclude with a difficulty inherent in Brentano's psychological approach to a priori knowledge.

David Pietraszewski's theory of social groups offers a developmentally plausible account of how we reason about group membership, as it delineates clear boundaries to the hypothesis space that children must navigate. Merits notwithstanding, the account remains silent with respect to the arbitration problem: It does not explain how children can appropriately select among competing frames when interpreting social interactions.

This paper explores a variety of kinds of apparent disagreement of which it may be held that they involve failure to disagree in that, at least in some broad sense, the disputants use the same words to express different meanings or concepts. It is argued that it is hard to rebut the claim that some apparent disagreements about personal identity fall into a particular sub-category of this broad type. I conclude both that a "constrained" relativism which I call "quasi-relativism" is (...) appropriate in regard to some central personal-identity debates, and also that, in order to avoid the lamentable conclusion that there is no real disagreement at all in these debates, we should embrace the idea that there is a non-cognitive element in personal identity claims, in virtue of the tight conceptual relations between personal identity claims and value claims of various kinds.

Cet article traite de la question méta-sémantique de ce qui permet au souvenir épisodique d’avoir le contenu sémantique qui est le sien. Il adopte une position singulariste quant au contenu du souvenir et critique la justification méta-sémantique relationnaliste de cette position. Selon celle-ci, le contenu du souvenir est singulier parce que le souvenir consiste en une relation d’accointance avec l’événement passé. L’article oppose un argument causal et un argument sémantique à cette analyse puis montre que les deux traits du souvenir (...) que l’idée d’accointance est censée expliquer – la phénoménologie et la singularité du souvenir – peuvent l’être au moyen de modèles singularistes non fondés sur l’accointance.

Causal pre-emption scenarios are problematic for the counterfactual framework of causation (CFC) because people judge an action to be the actual cause of an outcome although the outcome would have occurred anyway due to the action of a pre-empted alternative cause. We propose that commonsense causal questions typically probe specific events that actually happened as and how they did, and show that counterfactuals that probe specific events match selections of actual cause, and dissociations only occur with non-specific counterfactuals. In addition, (...) the pre-empted action is often selected as the or an actual cause when it causes the pre-empting action (auto-pre-emption). Judgements of an action’s responsibility for the outcome track judgements of actual cause following the legal sine qua non principle. Agent reproach is also influenced by the agent's intention. The effects of causal dependency structure and counterfactual question type are robust across the intentionality of the pre-empting action and scenario content. (shrink)

In affective neuroscience, constructivist models are acutely influenced by the modern technological evolution, which underwrites an ongoing epistemological substitution of techne for episteme. Evidenced symptomatically in the influence of artificial intelligence (AI), affective artefacts, these models inform an ontological incursion of techne seen to coincide with posthumanist aspirations and anthropology. It is from the perspective of this neuroscientific techne that posthumanism views the human being as increasingly ill adapted to the modern technological civilization, which, conversely, is understood to require a (...) technical governance of the sort envisioned through AI. Among the projects thought necessary for implementing this framework is a recasting of the human emotional spectrum. Revealed through its techne recasting, however, are explanatory commitments to a metaphysic of extrinsic and contiguous causes, where malleability is ontologically constitutive. Aligned with posthumanist assertions malleability is invoked to argue for a rapid advance of the human form, normatively driven by enlightenment ideals. The ontological claim, however, dispenses with the stability of an a priori, intersubjective and interrelational metaphysical form that undergirds the emotions, leading to the collapse of a definitional anthropos. This paper will argue that techne models of the emotions selectively endorse philosophy of science commitments, thereby introducing a normative inversion that deconstructs the notion of anthropology pursued in posthumanist aspirations.

Whole brain failure constitutes the diagnostic criterion for death determination in most clinical settings across the globe. Yet the conceptual foundation for its adoption was slow to emerge, has evoked extensive scientific debate since inception, underwent policy revision, and remains contentious in praxis even today. Complications result from the need to relate a unitary construal of the death event with an adequate account of organismal integration and that of the human organism in particular. Advances in the neuroscience of higher human (...) faculties, such as the self, personal identity, and consciousness, and dynamical philosophy of science accounts, however, are yielding a portrait of higher order global integration shared between body and brain. Such conceptual models of integration challenge a praxis relying exclusively on a neurological criterion for death. (shrink)

There has been increasing interest over the last few decades in the study of the effective content of Mathematics. One field whose effective content has been the subject of a large body of work, dating back at least to the early 1960s, is model theory. Several different notions of effectiveness of model-theoretic structures have been investigated. This communication is concerned withcomputablestructures, that is, structures with computable domains whose constants, functions, and relations are uniformly computable.In model theory, we identify isomorphic structures. (...) From the point of view of computable model theory, however, two isomorphic structures might be very different. For example, under the standard ordering of ω the success or relation is computable, but it is not hard to construct a computable linear ordering of type ω in which the successor relation is not computable. In fact, for every computably enumerable degree a, we can construct a computable linear ordering of type ω in which the successor relation has degree a. It is also possible to build two isomorphic computable groups, only one of which has a computable center, or two isomorphic Boolean algebras, only one of which has a computable set of atoms. Thus, for the purposes of computable model theory, studying structures up to isomorphism is not enough. (shrink)

ABSTRACTAccording to difference-based models of causal judgement, the epistemic state of the agent should not affect judgements of cause. Four experiments examined opportunity chains in which a physical event enabled a subsequent proximal cause to produce an outcome. All four experiments showed that when the proximal cause was a human action, it was judged as more causal if the agent was aware of his opportunity than if he was not or if the proximal cause was a physical event. The first (...) two experiments showed that these preferences could not be explained in terms of differences in perceived conditional probability, social controllability or perceptions of the causal sequence as forming a single unit. The third experiment showed that awareness affected the perceived deliberateness with which the action brought the outcome about but not its perceived voluntariness. The fourth experiment showed that... (shrink)

Le déficit d’explicabilité des techniques d’apprentissage machine (AM) pose des problèmes opérationnels, juridiques et éthiques. Un des principaux objectifs de notre projet est de fournir des explications éthiques des sorties générées par une application fondée sur de l’AM, considérée comme une boîte noire. La première étape de ce projet, présentée dans cet article, consiste à montrer que la validation de ces boîtes noires diffère épistémologiquement de celle mise en place dans le cadre d’une modélisation mathéma- tique et causale d’un phénomène (...) physique. La différence majeure est qu’une méthode d’AM ne prétend pas représenter une causalité entre les paramètres d’entrées et ceux de sortie. Après avoir proposé une clarification et une adaptation des notions d’inter- prétabilité et d’explicabilité telles qu’on les rencontre dans la littérature déjà abondante sur le sujet, nous montrons dans cet article l’intérêt de mettre en œuvre les distinctions épistémologiques entre les différentes fonctions épistémiques d’un modèle, d’une part, et entre la fonction épistémique et l’usage d’un modèle, d’autre part. Enfin, la dernière partie de cet article présente nos travaux en cours sur l’évaluation d’une explication, qui peut être plus persuasive qu’informative, ce qui peut ainsi causer des problèmes d’ordre éthique.

Einstein’s theory of Special relativity is founded on an error made by Hendrick Lorentz. It is not necessary to expose the mathematical inconsistencies of special relativity, since the theory collapses by simply exposing the error made by Lorentz. In doing so, it not only causes special relativity to collapse, but also general relativity, and the many theories built upon these two deceptive theories. There are many claims of tests made which supposedly prove SR or GR, such as the eclipse of (...) 1919, the Hafele-Keating experiment, GPS, the orbit of Mercury, and muons. The error of these will also be shown as well as an area of astronomy which has been negatively impacted by SR.

The fifth part bears on Stumpf’s debate with Mach on psychophysical relations and I shall conclude on Husserl’s criticism of Mach’s alleged logical psychologism. (shrink)

There is a widespread phenomenon that we call linguistic imposters. Linguistic imposters are systematic misuses of expressions that misusers mistake with their conventional usages because of misunderstanding their meaning. Our paper aims to provide an initial framework for theorising about linguistic imposters that will lay the foundation for future philosophical research about them. We focus on the misuses of the expressions ‘grooming’ and ‘critical race theory’ as our central examples of linguistic imposters. We show that linguistic imposters present a distinctive (...) phenomenon by comparing them to some adjacent phenomena, namely conceptual engineering, linguistic hijacking and dogwhistles. We also address four objections about the extensional adequacy of our definition of linguistic imposters. Finally, we argue that, as linguistic imposters spread, they make some inferences featuring misused expressions more cognitively accessible and seemingly socially licensed to misusers and discuss four types of harms that linguistic imposters are conducive to through these effects.
