This study explores the way that belief systems, interactions with social or experimental environments, and skills at the “control” level in decision‐making shape people's behavior as they solve problems. It is argued that problem‐solvers' beliefs (not necessarily consciously held) about what is useful in mathematics may determine the set of “cognitive resources” at their disposal as they do mathematics. Such beliefs may, for example, render inaccessible to them large bodies of information that are stored in long‐term memory and that are (...) easily retrieved in other circumstances. In other cases, individuals' reactions to an experimental setting (fear of failure, or the desire to “look mathematical” while being videotaped) may induce behavior that is almost pathological—and at the same time, so consistent that it can be modeled. In general, such “environmental” factors establish the context within which individuals access and utilize the information potentially at their disposal.Protocols illustrating these points are presented and discussed. A model based on an axiomatization of students' beliefs about plane geometry is outlined, and is shown to correspond closely to their problem‐solving performance. A framework is offered for analyzing problem‐solving performance at three qualitatively different levels: access to cognitive resources stored in LTM, executive or control decision‐making, and belief systems.

Most accounts of cognitive scaffolding focus on ways that external structure can support or augment an agent’s cognitive capacities. We call cases where the interests of the user are served benign scaffolding and argue for the possibility and reality of hostile scaffolding. This is scaffolding which depends on the same capacities of an agent to make cognitive use of external structure as in benign cases, but that undermines or exploits the user while serving the interests of another agent. We develop (...) criteria for scaffolding being hostile and show by reference to examples including the design features of electronic gambling machines and casino management systems that hostile scaffolding exists and can be highly effective. In cases where the scaffolding is deep and permits the offloading of significant cognitive work, hostile scaffolding exploitatively manipulates cognitive processing itself. Given the extent of human reliance on scaffolding this is an important and neglected vulnerability. [This is an updated version of the paper, added in February 2023.]. (shrink)

Bernard Gert claims that the project of justifying morality is “the primary task” of his major work, Morality: Its Nature and Justification. However, the arguments for and the point of his justification are not entirely clear. Unfortunately, critical work on Gert’s theory of morality has not included detailed attention to his attempt to justify morality. Part I of this two-part essay offers a systematic examination and assessment of Gert’s justification. It is argued that Gert’s justification is successful, but limited in (...) its scope. (shrink)

A striking empirical finding about color perception is that normal perceivers disagree about which hues are pure. (Pure hues contain no perceived admixture of any other color.) This finding poses a prima facie problem for color objectivism and representationalist accounts of perceptual experience. Michael Tye attempts to resolve this problem by arguing that pure hues do exist as objective properties of ordinary objects, but that human color detection mechanisms did not evolve with sufficient refinement to allow us to determine which (...) hues are the pure ones. I argue that Tye’s attempted solution fails, and that the most reasonable conclusion consistent with color objectivism is that pure hues do not exist. (shrink)

This paper argues for a physicalistic interpretation of Wittgenstein's Tractatus Logico-Philosophicus. Wittgenstein's general conception of world and language analysis is interpreted and exemplified in relation to the historical background of the psychophysical analysis of sense data and, in particular, color analysis. Three of his main principles of analysis—the principle of independence, the context principle and the principle of atomism—are interpreted and justified on the background of physicalism. From his proof of color exclusion in the Tractatus, it is shown that Wittgenstein (...) had a detailed conception of how philosophy should fulfil the task of distinguishing between sense and nonsense using physicalistic presuppositions.

In lieu of an abstract, here is a brief excerpt of the content:Book Reviews 137 The Meanings of Landscape: Essays on Place, Space, Environment and Justice BY KENNETH R. OLWIG London: Routledge, 2019 REVIEWED BY TIMM SCHÖNFELDER Landscape is more than spatial scenery that meets the eye: it is an anthropogenic artefact, an intellectual construct, a mirror of culture; it even has its own language.1 This broadness is reflected in the compilation of nine authoritative essays by the geographer (...) and professor of landscape architecture Kenneth R. Olwig that were published during the past quarter of a century and are now molded into a more coherent whole. In this regard, the present volume can be considered the pinnacle of Olwig’s intellectual oeuvre. In a fervent foreword, the anthropologist Tim Ingold sets the tone when he urges the reader to shed the contemporary notion of what he terms “topophobia”—­ a lack of bond betweenpeopleandplaces—­andtoreinstatephilologyasacentralfield of interest after it was “relegated by techno-­ science to the margins of scholarship” (xv). To achieve this, the essays deal with an eclectic set of themes ranging from Ptolemy’s notion of “choros” as something similar to today’s understanding of landscape, to the humanistic geographer Yi-­Fu Tuan’s concept of “topophilia,” which is hailed as a guiding ideal for much of Olwig’s work. The articles are bound together by an introduction that quickly transcendsthegeometricallimitationsoflandscape,ontologicallyquestioning whether these can be representative of the world itself at all (3). The first chapter thus delves right into the etymologies of “landscape” and its historical implications in the Nordic countries and England with detours through Italy and the German lands. In a cursory, highly associative manner Olwig fathoms the respective cultural implications. Central is the idea that the concept of landscape is more than the mere scenicrepresentationofspaceitcametobeknownasinRenaissance art and culture.2 Rather, the Nordic variants of the word, like the Swedish landskap, are used to denote natural regions with their own polity that were then gradually subjected to a monarchic state, not least through the surveying and mapping of their territory (see also chapter two). ENVIRONMENT, SPACE, PLACE / VOLUME 13 / ISSUE 2 / 2021 138 At times, Olwig’s philological musings appear rather stretched, as when he associates the German word Grundgesetz (the “basic/­ fundamental law” of 1949, which until today serves as Germany’s constitution ) with a biopolitical dimension of “ground” as in “soil” (41).3 In cases like this, his use of literature is selective. This culminates in a problematic assessment of Nazi ideology as being motivated by a specific understanding of landscape. Statements like “there can be no doubt that the modern German conception of Landschaft was implicated in the promotion of blood-­ and-­ soil fascist ideology” (42) neglect important literature on the topic.4 Such generalizations are owed to the author’s sweeping tour de force approach. The reviewer would have preferred more guidance through the theoretical thickets by way of a clear, chronologically ordered argument. This is not helped by the occasional seeming inconsistency, as in the claim that the U.S. “inherited the British scenic idea of landscape” as a former colony while also being “very much the inheritor of German romantic ideas concerning the relation of culture to nature as expressed in the physical landscape” (45), which, in turn, showed parallels to “fascist landscapes” in the “attempt to cleanse geography of its environmentalist taint by making it a science of space” (42). This truly is a lot of ground to cover for one essay. The ensuing chapters, however, try to disentangle this inspired jumble. The second article, “Landscape, Place, and the State of Progress,” identifies a switch since the Renaissance from the idea of circuitous development to linear progress towards utopia. For Olwig, there is a “darker, Faustian side” to it that he identifies as the “dialectic of modernity,” which “opposes cosmic dreams of a utopian future to the topian exigencies of present and past”: to advance, the path had to be cleared of traditional elements (52). This materialized in courteous theatre as well as in Shakespeare’s popular plays, and in the new architecture of parks where landscape was symbolic for cultural and social progress (64). “Choros, place, and the spatialization of landscape” traces important theoretical threads within geography...

, David Bloor suggests that logical reasoning is radically relativistic in the sense that there are incompatible ways of reasoning logically, and no culturally transcendent rules of correct logical inference exist which could allow for adjudication of these different ways of reasoning. Bloor cites an example of reasoning used by the Azande as an illustration of such logical relativism. A close analysis of this reasoning reveals that the Azande's logic is in fact impeccably Aristotelian. I argue that the conclusions Bloor (...) can legitimately draw from his case study are not controversial and do nothing to make plausible the thesis of logical relativism. (shrink)

Phenomenology’s return to lived experience and “to the things themselves” is often contrasted with the synthesized perspective of science and its “view from nowhere.” The extensive use of neuropsychological case reports in Merleau-Ponty’s Phenomenology of Perception, however, suggests that the relationship between phenomenology and science is more complex than a sheer opposition, and a fruitful one for the praxis of medicine. Here, I propose a new reading of how Merleau-Ponty justifies his use of Adhémar Gelb and Kurt Goldstein’s reports on (...) Johann Schneider for his phenomenology of embodied perception. I argue that for Merleau-Ponty these neuropsychological case reports represent a coherent deformation of the intercorporeally expressed existence of Schneider that through speech fall again onto the common ground of perception, thereby allowing Merleau-Ponty to understand, in the equivalent sense delivered by language, Schneider’s total being and fundamental illness. I then discuss what Merleau-Ponty’s method implies for a phenomenological praxis of medicine, and for the role of science in this praxis. (shrink)

Das Buch entwickelt einen neuartigen, physikalistischen Interpretationsansatz zu Wittgensteins Tractatus Logico-Philosophicus. Das traditionelle Urteil, Wittgenstein habe im Tractatus keine klare Vorstellung der Analyse gehabt, wird widerlegt. Auf der Basis der Rekonstruktion der um die Jahrhundertwende etablierten Sinnesdatenanalysen im allgemeinen und der Farbanalysen im besonderen wird nachgewiesen, daß Wittgensteins Tractatus eine physikalische Sinnesdatenanalyse voraussetzt. Auf diesem Hintergrund werden Wittgensteins allgemeine Auffassungen zur Analyse der Welt und Sprache gedeutet, begründet und exemplifiziert. Der Tractatus liefert die philosophische Klärung des mechanistischen Weltbildes von Boltzmann (...) und Hertz. Er stellt die Mittel bereit, um den Sinn der Sätze zu analysieren und die logische Zulässigkeit von Aussagen zu prüfen. Die Anwendung dieser Mittel ist Aufgabe der Philosophie. Daß sie anwendbar sind und wie sie anzuwenden sind, demonstriert dieses Buch. (shrink)

In a previous issue of this journal, Michael Hicks challenges my critique of Wilfrid Sellars’s arguments against the given and against the foundationalist epistemology that relies on the idea of a sensory given. I had argued that Sellars’s well-known claim that the given is a myth does not succeed because at a critical juncture he misconstrued sense-datum theorists such as Bertrand Russell and H. H. Price. In his response to my argument, Hicks makes the striking claim that Sellars was not (...) targeting foundationalism at all in his discussion of the myth of the given. Hicks reconstructs a key argument in “Empiricism and the Philosophy of Mind” (EPM) in a way intended both to avoid any reference to foundationalism and to do a more effective job than does Sellars’s original argument in uncovering a dilemma for traditional empiricism. The present paper challenges Hicks on two fronts. First, it argues that Hicks’s reconstruction is not more successful than Sellars’s original argument. Second, a review of relevant passages in makes clear that the critique of foundationalism is a prominent aspect of Sellars’s multi-faceted attack on the given. The conclusion reasserts the significance of Sellars’s place in the history of twentieth-century analytic philosophy. (shrink)

This paper discusses a definition of logical validity of arguments that is provided by Christoph Schamberger in his book Logik der Umgangssprache (2016). The paper identifies some problems of the given definition. It argues that any definition reducing the logical validity of ordinary arguments to the logical validity of their formalization does not meet the criteria of non-circularity, unambiguousness, correctness and completeness. Finally, the paper shows that Schamberger’s filter logic brings about that his definition does also not meet the standards (...) of formal precision and explanatory power. (shrink)

This book addresses the implications of Richard Rorty’s rejection of experience. The author argues that there are ways to recover a concept of experience that is consistent with Rorty’s preference for a linguistic style of pragmatism.

One of the central logical ideas in Wittgenstein’sTractatus logico-philosophicusis the elimination of the identity sign in favor of the so-called “exclusive interpretation” of names and quantifiers requiring different names to refer to different objects and (roughly) different variables to take different values. In this paper, we examine a recent development of these ideas in papers by Kai Wehmeier. We diagnose two main problems of Wehmeier’s account, the first concerning the treatment of individual constants, the second concerning so-called “pseudo-propositions” (Scheinsätze) of (...) classical logic such as$a=a$or$a=b \wedge b=c \rightarrow a=c$. We argue that overcoming these problems requires two fairly drastic departures from Wehmeier’s account: (1) Not every formula of classical first-order logic will be translatable into asingleformula of Wittgenstein’s exclusive notation. Instead, there will often be a multiplicity of possible translations, revealing the original “inclusive” formulas to beambiguous. (2) Certain formulas of first-order logic such as$a=a$will not be translatable into Wittgenstein’s notation at all, being thereby revealed as nonsensical pseudo-propositions which should be excluded from a “correct” conceptual notation. We provide translation procedures from inclusive quantifier-free logic into the exclusive notation that take these modifications into account and define a notion of logical equivalence suitable for assessing these translations.

I argue that in “Empiricism and the Philosophy of Mind,” Wilfrid Sellars significantly misconstrued the early twentieth-century empiricists he was criticizing (empiricists such as Bertrand Russell, H.H. Price and C.I. Lewis). Because these philosophers and their theories were becoming passé (partly due to EPM itself but also due to broader trends), this misconstrual was not noted. As a result, Sellars’s most influential claim – that the given is a myth – did not receive the critical scrutiny that it should have (...) received prior to its widespread acceptance. (shrink)

A dialogue between someone who finds Sellars's Rylean myth in "Empiricism and the Philosophy of Mind" quite implausible and another who defends it.

The random nature of immunoglobulin gene segment rearrangement inevitably leads to the generation of self‐reactive B cells. Avoidance of destructive autoimmune reactions is necessary in order to maintain physiological homeostasis. However, current central and peripheral tolerance concepts fail to explain the massive number of autoantibody‐borne autoimmune diseases. Moreover, recent studies have shown that in physiological mouse models autoreactive B cells were neither clonally deleted nor kept in an anergic state, but were instead able to mount autoantibody responses. We propose that (...) activation of autoreactive B cells is induced by polyvalent autoantigen complexes that can occur under physiological conditions. Repeated encounter of autoantigen complexes leads to the production of affinity‐matured autoreactive IgM that protects its respective self‐targets from degradation. We refer to this novel mechanism as adaptive tolerance. This article discusses the discovery of adaptive tolerance and the unexpected role of high affinity IgM autoantibodies. (shrink)

Jonathan barnes argues that heraclitus's unity of opposites doctrine is logically contradictory in that it requires the coinstantiation of contrary properties. but barnes relies on rather strained interpretations of the doxography. heraclitus's unity of opposites doctrine is better understood as consisting of two aspects: (1) a claim that opposing qualities, rather than being coinstantiated in one thing, are related to one another via a process of cyclic transformation; and (2) an attempt to illustrate the limited and incomplete perspectives through which (...) heraclitus believed humanity ordinarily viewed the world.

Logical relativism is the view that a logical proposition is known just in case it is collectively endorsed in some culture. This striking and controversial view is defended by David Bloor and Richard C. Jennings. They cite in its support distinctive reasoning practices among the Azande as described by E. E. Evans-Pitchard. Jennings has challenged my critique of Bloor's logical relativism, claiming that my analysis is based on misunderstandings of Bloor and Evans-Pritchard. I argue that Jennings' clarifications of Bloor do (...) nothing to support the thesis of logical relativism, and that a direct examination of Evans-Pritchard's evidence suggests that the Azande reason just as we do.

I argue that we can achieve certainty about some empirical propositions. When someone is having a migraine and attending to it, she can be certain that she is in pain. I show that examples intended to undermine claims of certainty or to raise doubts about the reliability of introspection do not touch such cases. Traditional foundationalists have held that epistemically certain beliefs can serve as the basis for all one’s other justified beliefs. This is not so, because those beliefs that (...) are certain are spread too thinly to serve as broad justificatory foundations. Certainty has a different role. The best explanation for the existence of epistemically certain empirical beliefs is experientialism, the view that nondoxastic sensory experiences can justify beliefs. Experientialism then offers a framework for showing how the stream of sensory experiences can provide an adequate basis for the justification of our ordinary beliefs about the external world.

In contrast to Hintikka’s enormously complex distributive normal forms of first- order logic, this paper shows how to generate minimized disjunctive normal forms of first-order logic. An effective algorithm for this purpose is outlined, and the benefits of using minimized disjunctive normal forms to explain the truth conditions of propo- sitions expressible within pure first-order logic are presented.

In this paper I problematize the use of appeals to the common intuitions people have about the morality of our society’s current treatment of animals in order to defend that treatment. I do so by looking at recent findings in the field of cognitive science. First I will examine the role that appeals to common intuition play in philosophical arguments about the moral worth of animals, focusing on the work of Carl Cohen and Richard Posner. After describing the theory of (...) Moral Disengagement—which has been used to explain how people live with themselves when they commit acts that they themselves believe are wrong—I will review the recent empirical research that details the nature of the moral disengagement that accompanies animal treatment. This includes studies that reveal that those who eat animals engage in the following behaviors: They minimize the nature of the harm of killing animals by casting the practice in a positive light; They obscure personal responsibility by blaming others for harms; They minimize the effect of the conduct on the animals by avoiding reference to the animal origins of meat; They derogate vegetarians as a way of avoiding feelings of guilt for their own practices. Perhaps most importantly, a number of empirical studies have shown that people’s intuitions about the moral worth of animals are shaped by their practice of eating animals—and not the other way around. In addition to the studies on moral disengagement, there is another body of research that has attempted to discover what accounts for the individual differences in attitudes people have toward the moral worth of animals. These studies have linked masculinity and traits like Authoritarianism, Social Dominance Orientation and Right Wing Authoritarianism to the tendency to disregard the moral worth of animals. I will briefly summarize this body of research and will then conclude by arguing that this data should cause us to be highly skeptical of the value that the common intuition that people who eat animals have about the moral status of animals may have in helping us understand the actual moral worth of animals.

This article identifies problems with regard to providing criteria that regulate the matching of logical formulae and natural language. We then take on to solve these problems by defining a necessary and sufficient criterion of adequate formalization. On the basis of this criterion we argue that logic should not be seen as an ars iudicandi capable of evaluating the validity or invalidity of informal arguments, but as an ars explicandi that renders transparent the formal structure of informal reasoning.
