Modern logic is undergoing a cognitive turn, side-stepping Frege’s ‘antipsychologism’. Collaborations between logicians and colleagues in more empirical fields are growing, especially in research on reasoning and information update by intelligent agents. We place this border-crossing research in the context of long-standing contacts between logic and empirical facts, since pure normativity has never been a plausible stance. We also discuss what the fall of Frege’s Wall means for a new agenda of logic as a theory of rational agency, and what (...) might then be a viable understanding of ‘psychologism’ as a friend rather than an enemy of logical theory.

Presents a theory of bullshit, how it differs from lying, how those who engage in it change the rules of conversation, and how indulgence in bullshit can alter a person's ability to tell the truth.

What is it about relativism that justifies, or at least explains, its continued appeal in the face of relentless attacks through the history of philosophy? This paper explores a new answer to this old question, casting the response in metaphilosophical terms. § i introduces the problem. § ii argues that one part of the answer is that some of the well-known defences of relativism take it to be a philosophical stance—that is, a broad perspective or orientation with normative consequences—rather than (...) a doctrine or a thesis. § iii draws attention to an assumption, not always explicitly stated by its proponents, that the relativist stance leads to the cultivation of some key intellectual virtues. Open-mindedness, tolerance, intellectual humility, and curiosity are examples of the intellectual virtues that relativism can foster. § iv argues that the defence of relativism on the basis of the virtues that are assumed to follow from it, at best, is only partially successful. Moreover, there is a range of epistemic vices, resulting from the stance, that undercuts the virtue-based defence presented in § iii. (shrink)

Contemporary issues involving knowledge and science examined from a constructivist-pragmatist perspective often labeled "relativism." Individual chapters include a review of the difference between constructivist-pragmatist epistemology and "social constructivism;" an examination of recent writings by Bruno Latour; a critique of computational methods in literary studies; a skeptical look at current efforts to "integrate" the humanities and the natural sciences; and reflections on the social dynamics of belief in relation to denials of climate change and to hopes expressed by environmentalists.

This paper identifies and elucidates a hitherto unnamed epistemic vice: epistemic insouciance. Epistemic insouciance consists in a casual lack of concern about whether one’s beliefs have any basis in reality or are adequately supported by the best available evidence. The primary intellectual product of epistemic insouciance is bullshit in Frankfurt’s sense. This paper clarifies the notion of epistemic insouciance and argues that epistemic insouciance is both an epistemic posture and an epistemic vice. Epistemic postures are attitudes towards epistemic objects such (...) as knowledge, evidence, or inquiry. Epistemic vices are defined as character traits, attitudes, or thinking styles that systematically obstruct the gaining, keeping or sharing of knowledge. Epistemic insouciance is not just a posture but an affective posture. Such postures are distinguished from epistemic stances, which are policies that one can adopt or reject. Epistemic malevolence is an example of an epistemically vicious epistemic stance that issues in active attempts to undermine the knowledge possessed by a specified group of individuals. An example of epistemic malevolence in action is the so-called ‘tobacco strategy.’ I argue that epistemic malevolence undermines knowledge by instilling doubts about respectable sources of evidence.

Sandra Harding here develops further the themes first addressed in her widely influential book, The Science Question in Feminism, and conducts a compelling analysis of feminist theories on the philosophical problem of how we know what we ...

The paper outlines a view of normativity that combines elements of relativism and expressivism, and applies it to normative concepts in epistemology. The result is a kind of epistemological anti-realism, which denies that epistemic norms can be (in any straightforward sense) correct or incorrect; it does allow some to be better than others, but takes this to be goal-relative and is skeptical of the existence of best norms. It discusses the circularity that arises from the fact that we need to (...) use epistemic norms to gather the facts with which to evaluate epistemic norms; relatedly, it discusses how epistemic norms can rationally evolve. It concludes with some discussion of the impact of this view on "ground level" epistemology. (shrink)

The author of the highly popular book Think, which Time magazine hailed as "the one book every smart person should read to understand, and even enjoy, the key questions of philosophy," Simon Blackburn is that rara avis--an eminent thinker who is able to explain philosophy to the general reader. Now Blackburn offers a tour de force exploration of what he calls "the most exciting and engaging issue in the whole of philosophy"--the age-old war over truth. The front lines of this (...) war are well defined. On one side are those who believe in plain, unvarnished facts, rock-solid truths that can be found through reason and objectivity--that science leads to truth, for instance. Their opponents mock this idea. They see the dark forces of language, culture, power, gender, class, ideology and desire--all subverting our perceptions of the world, and clouding our judgement with false notions of absolute truth. Beginning with an early skirmish in the war--when Socrates confronted the sophists in ancient Athens--Blackburn offers a penetrating look at the longstanding battle these two groups have waged, examining the philosophical battles fought by Plato, Protagoras, William James, David Hume, Hans-Georg Gadamer, Jacques Derrida, Michel Foucault, Richard Rorty, and many others, with a particularly fascinating look at Nietzsche. Among the questions Blackburn considers are: is science mere opinion, can historians understand another historical period, and indeed can one culture ever truly understand another. Blackburn concludes that both sides have merit, and that neither has exclusive ownership of truth. What is important is that, whichever side we embrace, we should know where we stand and what is to be said for our opponents. (shrink)

§1 To many in or on the edges of the Academy, ”Relativism” is a word with overtones of sinister iconoclasm, representing a kind of intellectual and ethical free-for-all in which the traditional investigative virtues of clarity, rigour, objectivity, consistency and the unbiased pursuit of truth are dismissed as illusory and the great scientific constructions of the last two hundred years, together with our deepest moral convictions, rated merely as ‘our way of seeing’ the world, more elaborate and organised but otherwise (...) on all fours with the cosmology and customs of primitive tribes. In his short book, Paul Boghossian aims to address, and to expose as bankrupt, the idea that there is even a coherent, let alone defensible philosophical stance about truth and knowledge that can underwrite these ‘pluralist’, or ‘postmodernist’ tendencies. But since it is crucial to his project that his style of discussion make it available to non-specialists, much of the recent more technical, less emotional debate within analytical philosophy about relativism’s renaissance as a particular form of semantic theory is passed over unmentioned. Part of my aim in what follows is to illustrate how Boghossian's discussion connects quite straightforwardly with relativism in its contemporary analytical philosophical livery—what I have elsewhere called New Age relativism1— and how some of his critical arguments may be presented in that setting. My main contentions will be, first, that when relativism about epistemic justification, and about morals, are couched in the currently canonical sort of form, they still remain in range of artillery that Boghossian positions in chapter 6 of his book; second, that there is evasive action that they can..

What is empiricism and what could it be? Bas . van Fraassen, one of the world’s foremost contributors to philosophical logic and the philosophy of science, here undertakes a fresh consideration of these questions and offers a program for renewal of the empiricist tradition. The empiricist tradition is not and could not be defined by common doctrines, but embodies a certain stance in philosophy, van Fraassen says. This stance is displayed first of all in a searing, recurrent critique of metaphysics, (...) and secondly in a focus on experience that requires a voluntarist view of belief and opinion. Van Fraassen focuses on the philosophical problems of scientific and conceptual revolutions and on the not unrelated ruptures between religious and secular ways of seeing or conceiving of ourselves. He explores what it is to be or not be secular and points the way toward a new relationship between secularism and science within philosophy. (shrink)

Epistemic relativism has the contemporary academy in its grip. Not merely in the United States, but seemingly everywhere, most scholars working in the humanities and the social sciences seem to subscribe to some form of it. Even where the label is repudiated, the view is embraced. Sometimes the relativism in question concerns truth, sometimes justification. The core impulse appears to be a relativism about knowledge. The suspicion is widespread that what counts as knowledge in one cultural, or broadly ideological, setting (...) need not count as knowledge in another. (shrink)

Four people with radically different views meet on a train and talk about what they believe. Each starts off convinced that he or she is right; then doubts creep in. Timothy Williamson uses a fictional conversation to explore the philosophical debate over whether one point of view can be right and the other wrong. He invites the reader to decide.

From flea bites to galaxies, from love affairs to shadows, Paul Feyerabend reveled in the sensory and intellectual abundance that surrounds us. He found it equally striking that human senses and human intelligence are able to take in only a fraction of these riches. "This a blessing, not a drawback," he writes. "A superconscious organism would not be superwise, it would be paralyzed." This human reduction of experience to a manageable level is the heart of _Conquest of Abundance_, the book (...) on which Feyerabend was at work when he died in 1994. Prepared from drafts of the manuscript left at his death, working notes, and lectures and articles Feyerabend wrote while the larger work was in progress, _Conquest of Abundance_ offers up rich exploration and startling insights with the charm, lucidity, and sense of mischief that are his hallmarks. Feyerabend is fascinated by how we attempt to explain and predict the mysteries of the natural world, and he looks at the ways in which we abstract experience, explain anomalies, and reduce wonder to formulas and equations. Through his exploration of the positive and negative consequences of these efforts, Feyerabend reveals the "conquest of abundance" as an integral part of the history and character of Western civilization. "Paul Feyerabend... was the Norman Mailer of philosophy.... brilliant, brave, adventurous, original and quirky."—Richard Rorty, _New Republic_ "As much a smudged icon as a philosophical position holder, [Feyerabend] was alluring and erotic, a torch singer for philosophical anarchy."—Nancy Maull, _New York Times Book Review_ "[A] kind of final testament of Feyerabend's thought... Conquest of Abundance is as much the product of a brilliant, scintillating style as of an immense erudition and culture.... This book is as abundant and rich as the world it envisions."—Arkady Plotnitsky, _Chicago Tribune_. (shrink)
