Research shows that early scientific interest is associated with science degree completion and career selection. However, little is known about the conditions that support early scientific interest. Using a “funds of knowledge” theoretical framework, this study examined the role of parents, family, and extended social networks in fostering early interest in science. Using interview narratives from 116 scientists (physicists and chemists) in the United States, we conducted a qualitative thematic content analysis. Findings suggest that children who become scientists in adulthood (...) often received early, informal opportunities to use and manipulate material objects and discover how the world works. Second, families used a wide variety of scientific terms at home and encouraged children to pursue their interests whether in science or other fields. Third, these future scientists were often networked with extended family members or friends to observe and do science when they were quite young. Collectively, these findings highlight the specific ways in which families fostered early scientific interest and aided in supporting a student-directed learning environment. (shrink)

In this paper, I explore the question of whether the expected consequences of holding a belief can affect the rationality of doing so. Special attention is given to various ways in which one might attempt to exert some measure of control over what one believes and the normative status of the beliefs that result from the successful execution of such projects. I argue that the lessons which emerge from thinking about the case ofbelief have important implications for the way we (...) should think about the rationality of a number of other propositional attitudes,such as regret, desire, and fear. Finally,I suggest that a lack of clarity with respect to the relevant issues has given rise to a number of rather serious philosophical mistakes. (shrink)

The passage above comes from the opening pages of Merleau-Ponty’s essay on Edmund Husserl. It proposes a risky interpretive principle. The main feature of this principle is that the seminal aspects of a thinker’s work are so close to him that he is incapable of articulating them himself. Nevertheless, these aspects pervade the work, give it its style, its sense and its direction, and therefore belong to it essentially. As Martin Heidegger writes, in a passage quoted by Merleau-Ponty: " The (...) greater the work of a thinker – which in no way coincides with the breadth and number of writings – the richer is what is un-thought in this work, which means, that which emerges in and through this work as having not yet been thought. 2 " The goal of Merleau-Ponty’s essay, he says, is “to evoke this un-thought-of element in Husserl’s thought”. 3.

I begin by examining a recent debate between John McDowell and Christopher Peacocke over whether the content of perceptual experience is non-conceptual. Although I am sympathetic to Peacocke’s claim that perceptual content is non-conceptual, I suggest a number of ways in which his arguments fail to make that case. This failure stems from an over-emphasis on the "fine-grainedness" of perceptual content - a feature that is relatively unimportant to its non-conceptual structure. I go on to describe two other features of (...) perceptual experience that are more likely to be relevant to the claim that perceptual content is non-conceptual. These features are 1) the dependence of a perceived object on the perceptual context in which it is perceived and 2) the dependence of a perceived property on the object it is perceived to be a property of.

A number of authors have argued recently that the content of perceptual experience can, and even must, be characterized in conceptual terms. Their claim, more precisely, is that every perceptual experience is such that, of necessity, its content is constituted entirely by concepts possessed by the subject having the experience. This is a surprising result. For it seems reasonable to think that a subject’s experiences could be richer and more fine-grained than his conceptual repertoire; that a subject might be able, (...) for example, to discriminate in experience more shades of colors than he has color concepts. The key move in their argument, therefore, is to articulate the conceptual content of experience using demonstrative, instead of general, concepts. For instance, these authors argue that the content of my perceptual experience of a particular shade of green is properly characterized in terms of the concept expressed by the linguistic utterance “that shade”. Even if I don’t possess a general concept for the shade I’m seeing—a concept of the kind typically expressed using color names like ‘chartreuse’ or ‘lime’—nevertheless, these authors argue, the content of the experience can still be characterized conceptually using a demonstrative concept that I do possess.

There you are at the opera house. The soprano has just hit her high note – a glassshattering high C that fills the hall – and she holds it. She holds it. She holds it. She holds it. She holds it. She holds the note for such a long time that after a while a funny thing happens: you no longer seem only to hear it, the note as it is currently sounding, that glass-shattering high C that is loud and (...) high and pure. In addition, you also seem to hear something more. It is difficult to express precisely what this extra feature is. One is tempted to say, however, that the note now sounds like it has been going on for a very long time. Perhaps it even sounds like a note that has been going on for too long. In any event, what you hear no longer seems to be limited to the pitch, timbre, loudness, and other strictly audible qualities of the note. You seem in addition to experience, even to hear, something about its temporal extent. (shrink)

Epistemic luck has been the focus of much discussion recently. Perhaps the most general knowledge-precluding type is veritic luck, where a belief is true but might easily have been false. Veritic luck has two sources, and so eliminating it requires two distinct conditions for a theory of knowledge. I argue that, when one sets out those conditions properly, a solution to the generality problem for reliabilism emerges.

Safe Safety arguments are key components in a safety case. Too often, safety arguments are constructed without proper reasoning. To address this, we argue that informal logic argument schemes have important roles to play in safety argument construction and reviewing process. Ten commonly used reasoning schemes in computer system safety domain are proposed. The role of informal logic dialogue games in computer system safety arguments reviewing is also discussed and the intended work in this area is proposed. It is anticipated (...) that this work will contribute toward the development of computer system safety arguments, and help to move forward the interplay between research in informal logic and research in computer system safety engineering.

Van Fraassen does not argue that everyone should be a constructive empiricist. He claims only that constructive empiricism (CE) is a coherent post-positivist alternative to realism, notwithstanding the realist's charge that CE is arbitrary and irrational. He does argue, however, that the empiricist is obliged to limit belief as CE prescribes. Criticism of CE has been largely directed at van Fraassen's claim that CE is a coherent option. Far less attention has been directed at his claim that empiricists should be (...) constructive empiricists. I consider his various attempts to support this claim, conclude that they are unsuccessful, and suggest that the empiricist who repudiates CE does not thereby abandon contemporary empiricism itself.

In The Foundations of Arithmetic, Gottlob Frege contended that the difference between concepts and objects was absolute. He meant that no object could be a concept and no concept an object. Benno Kerry disagreed; he contended that a concept could be an object, and that therefore the difference between concepts and objects was only relative. In this book, Jolley aims to understand the debate between Frege and Kerry. But Jolley's purpose is not so much to champion either side; rather, it (...) is to utilize an understanding of the debate to shed light on the work of Ludwig Wittgenstein-and vice versa. Jolley not only sifts through the debate between Frege and Kerry, but also through subsequent versions of the debate in J. J. Valberg and Wilfred Sellars. Jolley's goal is to show that the central notion of Philosophical Investigations, that of a 'conceptual investigation', is a legacy of the Frege/Kerry debate and also a contribution to it. Jolley concludes that the difference between concepts and objects is as absolute in its way in Philosophical Investigations as it was in The Foundations of Arithmetic and that recognizing the absoluteness of the difference in Philosophical Investigations provides a beginning for a 'resolute' reading of Wittgenstein's book.

This paper presents an integrative, descriptive model of ethical decision making, with special attention given to issues of measurement. After building the model, hypotheses are developed from a portion of it. These hypotheses are tested in an exploratory analysis to determine if further research and testing of this model and the measurement instruments it employs are warranted.

This paper places formal learning theory in a broader philosophical context and provides a glimpse of what the philosophy of induction looks like from a learning-theoretic point of view. Formal learning theory is compared with other standard approaches to the philosophy of induction. Thereafter, we present some results and examples indicating its unique character and philosophical interest, with special attention to its unified perspective on inductive uncertainty and uncomputability.

I propose that empirical procedures, like computational procedures, are justified in terms of truth-finding efficiency. I contrast the idea with more standard philosophies of science and illustrate it by deriving Ockham's razor from the aim of minimizing dramatic changes of opinion en route to the truth.

In this monograph on Luce Irigay, Kelly Ives explores the French thinker's ideas on the politics of sexual difference.

One construal of convergent realism is that for each clear question, scientific inquiry eventually answers it. In this paper we adapt the techniques of formal learning theory to determine in a precise manner the circumstances under which this ideal is achievable. In particular, we define two criteria of convergence to the truth on the basis of evidence. The first, which we call EA convergence, demands that the theorist converge to the complete truth "all at once". The second, which we call (...) AE convergence, demands only that for every sentence in the theorist's language, there is a time at which the theorist settles the status of the sentence. The relative difficulties of these criteria are compared for effective and ineffective agents. We then examine in detail how the enrichment of an agent's hypothesis language makes the task of converging to the truth more difficult. In particular, we parametrize first-order languages by predicate and function symbol arity, presence or absence of identity, and quantifier prefix complexity. For nearly each choice of values of these parameters, we determine the senses in which effective and ineffective agents can converge to the complete truth on an arbitrary structure for the language. Finally, we sketch directions in which our learning theoretic setting can be generalized or made more realistic. (shrink)

In this essay, I respond to A. W. Moore’s instructive chapter on Frege. I respond by asking various questions, and I question particularly Moore’s claim that Frege, in reacting to Benno Kerry, falls into Hegelian excess. I toy with responding to my question by regarding Frege as anticipating a Wittgensteinian-Heideggerian exaction. It remains unclear whether this constitutes (much) progress.

What follows is talky—I skitter across a number of difficult topics much too quickly and with little attempt to defend what I say. I may be able to add some defense later in discussion, but I don't promise anything much and certainly nothing fancy. I am still very much in the process of thinking about these topics, and I aim to do no more than to perhaps nudge you to think about them too.By "poetry" in what follows, I typically mean (...) "lyric poetry." There are poems and poems and poems, and the dactyls make a difference, as do many other features internal to poetry. I will also say upfront that I have no working definition of "lyric poetry." I also have no working definition of "philosophy," although I will be... (shrink)

Prior research suggests that most people perceive themselves to be more altruistic than the average population, an observation known as the better-than-average (BTA) effect. Understanding the BTA effect carries significant public health implications, as self-perceived altruism is closely related to altruistic behaviors, which plays a significant role in individual and societal well-being. However, little is known about whether subpopulations with specific sociodemographic profiles are more likely to hold BTA altruistic self-perceptions, making it difficult to design targeted programs based on multiple (...) sociodemographic characteristics to promote altruistic behaviors. This study addresses this gap by identifying the sociodemographic profiles of populations who are more likely to exhibit BTA effects on trait altruism. Data were derived from a representative sample of Hong Kong citizens (n= 1,185) in the 2017 Hong Kong Altruism Survey. A latent class analysis was performed using four domains of sociodemographic characteristics: sex, age, religion, and socioeconomic status. Multivariate multinomial logistic regressions were conducted to examine associations between class membership, BTA effect, and altruistic behaviors. The results yielded four classes of sociodemographic profiles. Middle-aged, Christian/Catholic, highly educated, and high-income individuals (Class 4, 17.8%) were most likely to exhibit BTA effects and behave altruistically; Class 3 (14.0%) were older, male, no/other religious belief, low education, and least likely to exhibit BTA effects and behave altruistically. Findings improve the understanding of the sociodemographic profiles of people showing BTA effects and facilitate targeted policy development to effectively promote altruism. (shrink)

The anticipated social capabilities of robots may allow them to serve in authority roles as part of human-machine teams. To date, it is unclear if, and to what extent, human team members will comply with requests from their robotic teammates, and how such compliance compares to requests from human teammates. This research examined how the human-likeness and physical embodiment of a robot affect compliance to a robot's request to perseverate utilizing a novel task paradigm. Across a set of two studies, (...) participants performed a visual search task while receiving ambiguous performance feedback. Compliance was evaluated when the participant requested to stop the task and the coach urged the participant to keep practicing multiple times. In the first study, the coach was either physically co-located with the participant or located remotely via a live-video. Coach type varied in human-likeness and included either a real human, a Nao robot, or a modified Roomba robot. The second study expanded on the first by including a Baxter robot as a coach and replicated the findings in a different sample population with a strict chain of command culture. Results from both studies showed that participants comply with the requests of a robot for up to 11 min. Compliance is less than to a human and embodiment and human-likeness on had weak effects on compliance. (shrink)

Neste artigo, meu objetivo é analisar de que maneira o cientista, no âmbito das Ciências Naturais, é educado para assimilar, aplicar e articular um determinado paradigma na solução dos problemas de ciência normal, sem colocá-lo (o paradigma) criticamente em questão, assim qualquer erro que venha a ocorrer na pesquisa é atribuído ao cientista e não ao paradigma. Pretendo também, mostrar que o caráter dogmático do paradigma não permite que o cientista desenvolva pesquisas visando novas descobertas que não se enquadrem nos (...) parâmetros ditados pelo mesmo, tal atitude exige total aceitação e comprometimento da comunidade científica para com o paradigma aceito, gerando assim, uma espécie de profissão de fé na capacidade do paradigma em resolver os quebra-cabeças que se apresentam na prática da ciência normal.

In amblyopia, abnormal visual experience during development leads to an enduring loss of visual acuity in adulthood. Physiological studies in animal models suggest that intracortical GABAergic inhibition may mediate visual deficits in amblyopia. To better understand the relationship between visual cortical γ-aminobutyric acid (GABA) and perceptual suppression in persons with amblyopia (PWA), we employed magnetic resonance spectroscopy (MRS) to quantify GABA levels in both PWA and normally-sighted persons (NSP). In the same individuals, we obtained psychophysical measures of perceptual suppression for (...) a variety of ocular configurations. In PWA, we found a robust negative correlation between the depth of amblyopia (the difference in visual acuity between the amblyopic and non-amblyopic eyes) and GABA concentration that was specific to visual cortex and was not observed in a sensorimotor cortical control region. Moreover, lower levels of visual cortical GABA were associated with weaker perceptual suppression of the fellow eye by the amblyopic eye and stronger suppression of the amblyopic eye by the fellow eye. Taken together, our findings provide evidence that intracortical GABAergic inhibition is an important component of the pathology of human amblyopia and suggest possible therapeutic interventions to restore vision in the amblyopic eye through enhancement of visual cortical GABAergic signaling in PWA.

Drawing on the institutional history of the sperm bank and legacies of eugenics, we consider how spectrums of risk simultaneously constrain and expand possibilities for disability justice. We do so by examining the discourses surrounding US-based Xytex Corporation sperm bank Donor 9623, described as the ‘perfect’ donor but later discovered to have a criminal record and a diagnosis of schizophrenia. Haunted by the dread of disability, we examine how parents mark the fate of their donor-conceived child on a graded spectrum (...) of genetic and psychiatric risk, in need of perpetual monitoring and intervention. Using this case to understand the contemporary reorganization of disability via spectral risk, we advocate for a critical engagement with how disability haunting can enable us to better attend to the effects of the past and present in such a way that provokes a more collectively just future.
