The technology for the digitized text creates fluid meaning, representing its culture in transition from the dominance of the single-authored text with its hierarchically ordered system. This new architecture for the digitized word has been making explicit the shift from human consciousness reflecting the interiority of the self to a human consciousness reflecting self in relation to others. Educators using the technology of networked writing environments need to understand how the technology functions and intervenes for pedagogical processes during models of (...) asynchronous and synchronous collaborative writing. Both models support a constructivist view of learning; however, for each, educators need to consider the ethos of the writer as inhabiting a negotiated, shared space with readers during text production. As a consequence, cocognition may occur when writers share ideas and engage in the process of collaboration. (shrink)

In recent work Timothy Williamson argues that the epistemology of metaphysical modality is a special case of the epistemology of counterfactuals. I argue that Williamson has not provided an adequate argument for this controversial claim, and that it is not obvious how what he says should be supplemented in order to derive such an argument. But I suggest that an important moral of his discussion survives this point. The moral is that experience could play an epistemic role which (...) is more epistemically significant than a mere 'enabling' role but not equivalent to an evidential role. (shrink)

In this paper, we explore the traditional conception of a prioricity as epistemic independence of evidence from sense experience. We investigate the fortunes of the traditional conception in the light of recent challenges by Timothy Williamson. We contend that Williamson’s arguments can be resisted in various ways. En route, we argue that Williamson’s views are not as distant from tradition as they might seem at first glance.

From the 1910s through the 1930s, the American naturalist and photographer Arthur C. Pillsbury made time-lapse and microscopic films documenting what he, in common parlance, called the “miracles of plant life”. While these films are now mostly lost, they were part of Pillsbury’s prolific work as a conservationist and traveling film lecturer who used his cameras everywhere from Yosemite National Park to Samoa to promote both public understanding of plants and a desire to protect the natural world. Guiding this work (...) was Pillsbury’s belief that the nonhuman optics of the film camera, which revealed the animacy of plants, could also incite viewers to sympathize with them. In the context of the early American conservation movement, that sympathy stemmed in complicated ways from longstanding transcendental and pastoral ideas of nature that were entangled with imperialist visions of controlling nature. With an eye to that context, I show that Pillsbury’s filmmaking was not simply about using motion picture technologies to shape attitudes toward plants and nature more broadly; it was also about using nature to think through the techno-scientific possibilities of the cinema in the early part of the twentieth century.

Improbable knowing is knowing something even though it is almost certain on one’s evidence at the time that one does not know that thing. Once probabilities on the agent’s evidence are introduced into epistemic logic in a very natural way, it is easy to construct models of improbable knowing, some of which have realistic interpretations, for instance concerning agents like us with limited powers of perceptual discrimination. Improbable knowing is an extreme case of failure of the KK principle, that is, (...) of a case of knowing something even though one does not know at the time that one knows that thing. A generalization of the argument yields cases of improbable rationality, in which it is rational for one to do something even though it is almost certain on one’s evidence at the time that it is not rational for one to do that thing. When the models are elaborated to represent appearances and beliefs as well as knowledge, they turn out to contain Gettier cases. Neglect of the possibility of improbable knowing may cause some sceptical claims and claims of the non-closure of knowledge under competent deduction to look more plausible than they deserve to. A formal appendix explores the closely related question of the conditions under which a reflection principle is violated. The principle says that the evidential probability of a proposition conditional on the evidential probability of that proposition’s being c is itself c. (shrink)

There is a New Idea in epistemology. It goes by the name of ‘knowledge first,’ and it is particularly associated with Timothy Williamson’s book Knowledge and Its Limits. In slogan form, to put knowledge first is to treat knowledge as basic or fundamental, and to explain other states—belief, justification, maybe even content itself—in terms of knowledge, instead of vice versa. The idea has proven enormously interesting, and equally controversial. But deep foundational questions about its actual content remain relatively unexplored. (...) We think that a wide variety of views travel under the banner of ‘knowledge first’ (and that the slogan doesn’t help much with differentiating them). Furthermore, we think it is far from straightforward to draw connections between certain of these views; they are more independent than they are often assumed to be. Our project here is exploratory and clarificatory. We mean to tease apart various ‘knowledge first’ claims, and explore what connections they do or do not have with one another. Our taxonomy is offered in §2, and connections are explored in §3. The result, we hope, will be a clearer understanding of just what the knowledge first theses are. We conclude, in §4, with some brief suggestions as to how we think the various theses might be evaluated. (shrink)

Russo and Williamson (Int Stud Philos Sci 21(2):157–170, 2007) put forward the thesis that, at least in the health sciences, to establish the claim that C is a cause of E, one normally needs evidence of an underlying mechanism linking C and E as well as evidence that C makes a difference to E. This epistemological thesis poses a problem for most current analyses of causality which, in virtue of analysing causality in terms of just one of mechanisms or (...) difference making, cannot account for the need for the other kind of evidence. Weber (Int Stud Philos Sci 23(2):277–295, 2009) has suggested to the contrary that Giere’s probabilistic analysis of causality survives this criticism. In this paper, we look in detail at the case of medical imaging technology, which, we argue, supports the thesis of Russo and Williamson, and we respond to Weber’s suggestion, arguing that Giere’s account does not survive the criticism.

The late nineteenth to early twentieth century saw a small but dedicated rise in experimental rainmaking. The possibility that humanity might one day be able to control the weather – especially to alleviate drought – was very attractive to governments and private investors. The late nineteenth century was an era of scientific optimism and a number of rainmaking experiments across the world had brought the potential for weather control out of the realms of discourse and literature and further into tangible (...) near-future science. There has been a small but thorough historiographical literature on this subject, focusing largely on American, British, and Australian efforts. This article seeks to build on this by exploring the little-known history of rainmaking in Hong Kong before 1930, centering on a case study of a particular experiment intended to alleviate the disastrous drought of 1928–9. As was the case elsewhere, Hong Kong’s rainmaking efforts raised as much skepticism as they did support, with the government, scientists, and the general public in two minds about whether making rain was even possible. As such, this article aims to interrogate the concepts of the sociotechnical imaginary and the history of failure, while also contributing to the wider story of meteorological knowledge-making.

This article investigates the contribution made by indigenous employees to the work of the Hong Kong Observatory from its inception and into the early twentieth century. As has so often been the case in Western histories of science, the significance of indigenous workers and of women in the Hong Kong Observatory has been obscured by the stories of the government officials and observatory director(s). Yet without the employees, the service could not have functioned or grown. While the glimpses of their (...) work and lives are fleeting, often only revealed in minor archival references, this article seeks to interrogate these sources to make these workers’ lives visible and to offer an examination of everyday working relationships at this place and point in time. It focuses on three areas. First, an exploration of who these workers were, and the role they played at the observatory. Second, an investigation of their contribution to the nascent science of meteorology. Third, an examination of available evidence – levels of high staff turnover, complaints, instances of foot dragging, or working to rule, as well as the tenacity to continue for years under difficult working conditions – to demonstrate the ability of workers to reject or to negotiate with colonial/patriarchal authority. In profiling their stories, this article will add to the literature examining the lives of scientific workers and their contributions to science, the everyday cultural and social contexts of colonial meteorology, and the role of ordinary men and women in producing meteorological knowledge at this time.

Cameron and Williamson have provided a provocative and timely review of the ethical questions prompted by the birth of Dolly. The question Cameron and Williamson seek to address is “In the world of Dolly, when does a human embryo acquire respect?”. Their initial discussion sets the scene by providing a valuable overview of attitudes towards the embryo, summarising various religious, scientific, and philosophical viewpoints. They then ask, “What has Dolly changed?” and identify five changes, the first being that (...) fertilisation is no longer required to create an embryo. Following this analysis they then ask when an embryo created other than by fertilisation begins to acquire respect. This paper explores the ethical and legal issues highlighted by Cameron and Williamson’s paper. (shrink)

In this paper I consider a recent argument of Timothy Williamson’s that epistemic internalism and content externalism are indeed incompatible, and since he takes content externalism to be above reproach, so much the worse for epistemic internalism. However, I argue that epistemic internalism, properly understood, remains substantially unaffected no matter which view of content turns out to be correct. What is key to the New Evil Genius thought experiment is that, given everything of which the inhabitants are consciously aware, (...) the two worlds are subjectively indistinguishable for them, which is what matters on internalist accounts of epistemic justification. I argue that even if a standard moral of the New Evil Genius intuition is untenable due to considerations arising from content externalism, the case can be understood as supporting epistemic internalism in a way that is wholly compatible with content externalism. In short, epistemic internalism is committed to sameness of justificatory status between subjectively indistinguishable counterparts, not sameness of content of their justifiers. (shrink)

Williamson claims that we are cognitive homeless, and for most aspects of our cognitive life it is not the case that if we are in the mental state S we know or are in a position to know that we are in said mental state. In this paper, I critically examine Williamson’s argument, some common misconceptions, and provide a different understanding of the way we relate to our own mental states that shows how we are not always in (...) a condition of cognitive homelessness.

We implement a recent characterization of metaphysical indeterminacy in the context of orthodox quantum theory, developing the syntax and semantics of two propositional logics equipped with determinacy and indeterminacy operators. These logics, which extend a novel semantics for standard quantum logic that accounts for Hilbert spaces with superselection sectors, preserve different desirable features of quantum logic and logics of indeterminacy. In addition to comparing the relative advantages of the two, we also explain how each logic answers Williamson’s challenge to (...) any substantive account of determinacy: For any proposition p, what could the difference between “p” and “it’s determinate that p” ever amount to?

Some philosophers, like Kripke, Williamson, Hawthorne, and Turri, have offered examples of claims that are allegedly contingent and a priori justifiable. If any of these examples is genuine, this would upend the traditional epistemological classification on which (a) all and only a priori justifiable claims are necessary and (b) all and only a posteriori ones are contingent. I argue here that these examples are not genuine. This conclusion is not new, but the strategy pursued here is to formalize these (...) muchdiscussed examples in symbolic logics. Once formalized, a perspicuous representation of their logical form will bring into sharp relief that these examples are not both contingent and a priori. Two takeaways are (1) that the traditional epistemological classification remains plausible and (2) that one’s proposed examples of contingent a priori claims should be supported by a formalization in one’s preferred background symbolic logic.

K. R. Popper distinguished between two main uses of logic, the demonstrational one, in mathematical proofs, and the derivational one, in the empirical sciences. These two uses are governed by the following methodological constraints: in mathematical proofs one ought to use minimal logical means (logical minimalism), while in the empirical sciences one ought to use the strongest available logic (logical maximalism). In this paper I discuss whether Popper’s critical rationalism is compatible with a revision of logic in the empirical sciences, (...) given the condition of logical maximalism. Apparently, if one ought to use the strongest logic in the empirical sciences, logic would remain immune to criticism and, thus, non-revisable. I will show that critical rationalism is theoretically compatible with a revision of logic in the empirical sciences. However, a question that remains to be clarified by the critical rationalists is what kind of evidence would lead them to revise the system of logic that underlies a physical theory, such as quantum mechanics? Popper’s falsificationist methodology will be compared with the recently advocated extension of the abductive methodology from the empirical sciences to logic by T. Williamson, since both of them arrive at the same conclusion concerning the status of classical logic. (shrink)

In this paper, I consider a popular version of the clever student’s reasoning in the surprise examination case, and demonstrate that a valid argument can be constructed. The valid argument is a reductio ad absurdum with the proposition that the student knows on the morning of the first day that the teacher’s announcement is fulfilled as its reductio. But it would not give rise to any paradox. In the process, I criticize Saul Kripke’s solution and Timothy Williamson’s attack on (...) a key step of the student’s reasoning. I then consider the condemned prisoner case in W. V. Quine’s paper ‘On a So-Called Paradox’. I argue that the prisoner’s reasoning as conceived by Quine is more relevant and reasonable than the student’s argument in the popular version of the surprise examination case. I also argue that Quine’s criticism of the prisoner’s reasoning is correct, and therefore that the condemned prisoner case, and the surprise examination case as well, would not generate any paradox.

Gilbert Ryle claimed that intelligent actions and activities are not merely the external signs of inner mental workings but rather that such actions and activities are the workings of the mind itself. In this thesis I propose an interpretation and defence of sich claim, against a common an, in my view, mistaken way of understanding Ryle's position. In chapter [1]. I introduce the argumentative thread of this thesis and a more detailed overview of the chapters. In chapter [2], I criticise (...) Stanley and Williamson's understanding of Ryle's argument and position. In chapters [3]-[5] I examine Ryle's position and provide a way of understanding his view against what I take his main opponent, INTELLECTUALISM, to be. Chapter [6] offers an argument against INTELLECTUALISM as a way of motivating a Rylean account intelligent actions and activities. I conclude in chapter [7] with a response to purported counter-examples to the view I propose. (shrink)

We show that the contemporary debate surrounding the question “What is the norm of assertion?” presupposes what we call the quantitative view, i.e. the view that this question is best answered by determining how much epistemic support is required to warrant assertion. We consider what Jennifer Lackey ( 2010 ) has called cases of isolated second-hand knowledge and show—beyond what Lackey has suggested herself—that these cases are best understood as ones where a certain type of understanding , rather than knowledge, (...) constitutes the required epistemic credential to warrant assertion. If we are right that understanding (and not just knowledge) is the epistemic norm for a restricted class of assertions, then this straightforwardly undercuts not only the widely supposed quantitative view, but also a more general presupposition concerning the universalisability of some norm governing assertion—the presumption (almost entirely unchallenged since Williamson’s 1996 paper) that any epistemic norm that governs some assertions should govern assertions—as a class of speech act—uniformly.

A repackaged edition of the revered author's classic work that examines the four types of human love: affection, friendship, erotic love, and the love of God—part of the C. S. Lewis Signature Classics series. C.S. Lewis—the great British writer, scholar, lay theologian, broadcaster, Christian apologist, and bestselling author of Mere Christianity, The Screwtape Letters, The Great Divorce, The Chronicles of Narnia, and many other beloved classics—contemplates the essence of love and how it works in our daily lives in one of (...) his most famous works of nonfiction. Lewis examines four varieties of human love: affection, the most basic form; friendship, the rarest and perhaps most insightful; Eros, passionate love; charity, the greatest and least selfish. Throughout this compassionate and reasoned study, he encourages readers to open themselves to all forms of love—the key to understanding that brings us closer to God. (shrink)

Originally published in 1904, Whittaker’s A Treatise on the Analytical Dynamics of Particles and Rigid Bodies soon became a classic of the subject and has remained in print for most of these 108 years. In this paper, we follow the book as it develops from a report that Whittaker wrote for the British Society for the Advancement of Science to its influence on Dirac’s version of quantum mechanics in the 1920s and beyond.

First, some reminiscences. In the years 1973-80, when I was an undergraduate and then graduate student at Oxford, Michael Dummett’s formidable and creative philosophical presence made his arguments impossible to ignore. In consequence, one pole of discussion was always a form of anti-realism. It endorsed something like the replacement of truth-conditional semantics by verification-conditional semantics and of classical logic by intuitionistic logic, and the principle that all truths are knowable. It did not endorse the principle that all truths are known. (...) Nor did it mention the now celebrated argument, first published by Frederic Fitch (1963), that if all truths are knowable then all truths are known. (shrink)

In Campbell Soup Co. v. Allstate Insurance Co. ), the United States District Court for the Western District of Michigan, Southern Division, held that a health plan's coordination of benefits clause, covered under the Employee Retirement Income Security Act, does not preempt a similar no-fault automobile insurance clause in the absence of irreconcilable conflict. The court found that ERISA's policy of shielding plans from unanticipated claims could only be furthered when the plan had expressly disavowed such claims. Because the ERISA (...) plan in this case did not specifically subordinate itself to the no-fault policy, the district court found that the no-fault COB clause controlled. However, to escape this ruling, ERISA plans need only redraft their COB clauses specifically to disclaim liability in case of conflict with provisions of no-fault insurance policies. This caveat substantially limits the scope of the court's ruling. (shrink)

Objectives: This study aimed to determine attitudinal and self reported behavioural variations between medical students in different years to scenarios involving academic misconduct.Design: A cross-sectional study where students were given an anonymous questionnaire that asked about their attitudes to 14 scenarios describing a fictitious student engaging in acts of academic misconduct and asked them to report their own potential behaviour.Setting: Dundee Medical School.Participants: Undergraduate medical students from all five years of the course.Method: Questionnaire survey.Main measurements: Differences in medical students’ attitudes (...) to the 14 scenarios and their reported potential behaviour with regards to the scenarios in each of the years.Results: For most of the scenarios there was no significant difference in the response between the years. Significant differences in the responses were found for some of the scenarios across the years, where a larger proportion of year one students regarded the scenario as wrong and would not engage in the behaviour, compared to other years. These scenarios included forging signatures, resubmitting work already completed for another part of the course, and falsifying patient information.Conclusion: Observed differences between the years for some scenarios may reflect a change in students’ attitudes and behaviour as they progress though the course. The results may be influenced by the educational experience of the students, both in terms of the learning environment and assessment methods used. These differences may draw attention to the potential but unintentional pressures placed on medical students to engage in academic misconduct. The importance of developing strategies to engender appropriate attitudes and behaviours at the undergraduate level must be recognised. (shrink)

§1. The origins of recursion theory. In dedicating a book to Steve Kleene, I referred to him as the person who made recursion theory into a theory. Recursion theory was begun by Kleene's teacher at Princeton, Alonzo Church, who first defined the class of recursive functions; first maintained that this class was the class of computable functions ; and first used this fact to solve negatively some classical problems on the existence of algorithms. However, it was Kleene who, in his (...) thesis and in his subsequent attempts to convince himself of Church's Thesis, developed a general theory of the behavior of the recursive functions. He continued to develop this theory and extend it to new situations throughout his mathematical career. Indeed, all of the research which he did had a close relationship to recursive functions.Church's Thesis arose in an accidental way. In his investigations of a system of logic which he had invented, Church became interested in a class of functions which he called the λ-definable functions. Initially, Church knew that the successor function and the addition function were λ-definable, but not much else. During 1932, Kleene gradually showed1 that this class of functions was quite extensive; and these results became an important part of his thesis 1935a. (shrink)

Data science is characterized by engaging heterogeneous data to tackle real world questions and problems. But data science has no data of its own and must seek it within real world domains. We call this search for data “prospecting” and argue that the dynamics of prospecting are pervasive in, even characteristic of, data science. Prospecting aims to render the data, knowledge, expertise, and practices of worldly domains available and tractable to data science method and epistemology. Prospecting precedes data synthesis, analysis, (...) or visualization, and is constituted by the upstream work of discovering disordered or inaccessible data resources, thereafter to be ordered and rendered available for computation. Through this work, data science positions itself in the middle of all things—capable of engaging this, that, or any domain—and thus prospecting is a key driver of data science’s ongoing formation as a universal science.
