Alvin Goldman has criticized the idea that, when evaluating the opinions of experts who disagree, a novice should “go by the numbers”. Although Goldman is right that this is often a bad idea, his argument involves an appeal to a principle, which I call the non-independence principle, which is not in general true. Goldman's formal argument for this principle depends on an illegitimate assumption, and the examples he uses to make it seem intuitively plausible are not convincing. The failure of (...) this principle has significant implications, not only for the issue Goldman is directly addressing, but also for the epistemology of rumors, and for our understanding of the value of epistemic independence. I conclude by using the economics literature on information cascades to highlight an important truth which Goldman's principle gestures toward, and by mounting a qualified defense of the practice of going by the numbers.

The current public health crisis has exposed deep cracks in social equality and justice for marginalised and vulnerable communities around the world. The reported rise in the number of ‘do not resuscitate’ orders being imposed on people with disabilities has caused particular concerns from a human rights perspective. While the evidence of this is contested, this article will consider the human rights implications at stake and the dangers associated with using ‘quality of life’ measures as determinant of care in medical (...) decision-making and triage assessments.

We citizens of the 21st century live in a world where division of epistemic labour rules. Most of what we know we learned from the spoken or written word of others, and we depend in endless practical ways on the technological fruits of the dispersed knowledge of others—of which we often know almost nothing—in virtually every moment of our lives. Interest has been growing in recent years amongst philosophers, in the issues in epistemology raised by this fact. One issue concerns (...) the depth and extent of our epistemic dependence on testimony, as we may label this broad epistemic source: Do we have any knowledge at all that is free of epistemic dependence on what we have learned from others? A related question is whether our entitlement to believe what we have learned from others can be explained without invoking any epistemic principles special to testimony. These questions concern, as it were, the macro-epistemology of testimony. In the present discussion I shall focus instead on the micro foundations. Testimony, in our broad sense, can occur through an extensive range of types of spoken and written means of purportedly factual communication, including telephone calls, e-mails and personal letters, lectures and radio broadcasts, newspapers, textbooks and encyclopaedias, personal diaries, and public records of all kinds. But the central paradigm—what started the whole communication thing off—is surely that of face-to-face spoken encounter, when one person tells something to another, thereby intending and hoping to share her knowledge with her audience. I begin by describing the speech act of telling, identifying what takes place in a felicitous act of telling. From the nature of the speech act of telling, we see precisely how it is that knowledge is, when all goes as it should, acquired from teller by trusting hearer, in such an act, and in acts of testimony more broadly.

Sweeping in scope, penetrating in analysis, and generously illustrated with examples from the history of science, this new and original approach to familiar questions about scientific evidence and method tackles vital questions about science and its place in society. Avoiding the twin pitfalls of scientism and cynicism, noted philosopher Susan Haack argues that, fallible and flawed as they are, the natural sciences have been among the most successful of human enterprises-valuable not only for the vast, interlocking body of knowledge they (...) have discovered, and not only for the technological advances that have improved our lives, but as a manifestation of the human talent for inquiry at its imperfect but sometimes remarkable best. This wide-ranging, trenchant, and illuminating book explores the complexities of scientific evidence, and the multifarious ways in which the sciences have refined and amplified the methods of everyday empirical inquiry; articulates the ways in which the social sciences are like the natural sciences, and the ways in which they are different; disentangles the confusions of radical rhetoricians and cynical sociologists of science; exposes the evasions of apologists for religious resistance to scientific advances; weighs the benefits and the dangers of technology; tracks the efforts of the legal system to make the best use of scientific testimony; and tackles predictions of the eventual culmination, or annihilation, of the scientific enterprise. Writing with verve and wry humor, in a witty, direct, and accessible style, Haack takes readers beyond the "Science Wars" to a balanced understanding of the value, and the limitations, of the scientific enterprise.

“Ethics” is used as a label for a new kind of expertise in the field of science and technology. At the same time, it is not clear what ethical expertise consists in and what its political status in modern democracies can be. Starting from the “participatory turn” in recent social research and policy, we will argue that bioethical reasoning has to include public views of and attitudes towards biomedicine. We will sketch the outlines of a bioethical conception of “public understanding (...) of ethics,” addressing three different issues: the methodological relevance of moral questions and problems raised by lay persons in everyday life regarding biomedicine and technology, the normative relevance of such lay moralities for the justification of ethical decisions, and the necessity of public deliberation in this context. Finally, we draw conclusions in view of the concepts and methods such a conception of “public understanding of ethics” should employ. (shrink)

The COVID-19 pandemic has raised a host of ethical challenges, but key among these has been the possibility that health care systems might need to ration scarce critical care resources. Rationing p...

The current Covid-19 pandemic is illustrative of both the need of more experts and of the difficulties that can arise in the face of their decisions. This happens, we argue, because experts usually interact with society through a strongly naturalistic framework, which often places experts’ epistemic authority (understood as neutrality and objectivity) at the centre, sometimes at the expenses of other pluralistic values (such as axiological ones) that people (often non-experts) cherish. In this paper, we argue that we need to (...) supplement such a strong naturalistic framework used to promote epistemic authority with a number of virtues -both intellectual and ethical- which include i. intellectual humility, ii. courage, iii. wisdom and cares, as well as iv. relational autonomy. To illustrate this claim, we discuss these ideas in the context of the Covid-19 pandemic and analyse a set of real-life examples where important decisions have been delegated to experts merely based on their epistemic authority. We use the illustrative failures described in the case studies above-mentioned to call for a revision of current understandings of expertise (merely based on epistemic soundness). Specifically, we argue that in social contexts we increasingly need “experts in action”; that is, people with certified specialist knowledge, who can however translate it into practical suggestions, decisions, and/or public policies that are ethically more balanced and that ultimately lead to fairer, more inclusive, and more representative decisions.

Mainstream epistemology is a highly theoretical and abstract enterprise. Traditional epistemologists rarely present their deliberations as critical to the practical problems of life, unless one supposes—as Hume, for example, did not—that skeptical worries should trouble us in our everyday affairs. But some issues in epistemology are both theoretically interesting and practically quite pressing. That holds of the problem to be discussed here: how laypersons should evaluate the testimony of experts and decide which of two or more rival experts is most (...) credible. It is of practical importance because in a complex, highly specialized world people are constantly confronted with situations in which, as comparative novices, they must turn to putative experts for intellectual guidance or assistance. It is of theoretical interest because the appropriate epistemic considerations are far from transparent; and it is not clear how far the problems lead to insurmountable skeptical quandaries. This paper does not argue for flat-out skepticism in this domain; nor, on the other hand, does it purport to resolve all pressures in the direction of skepticism. It is an exploratory paper, which tries to identify problems and examine some possible solutions, not to establish those solutions definitively. (shrink)

Many governments have seen digital health technologies as promising tools to tackle the current COVID-19 pandemic. A much-talked example in this context involves the recent deluge of digital contact tracing apps aimed at detecting Covid-19 exposure. In this short contribution we look at the bio-political justification of this phenomenon and reflect on whether DCT apps constitute, as it is often argued, a serious potential breach of our right to privacy. Despite praising efforts attempting to develop legal and ethical frameworks for (...) DCT apps’ usage; we argue that such endeavours are not sufficient to tackle the more fundamental problem of mass surveillance, which will remain largely unaddressed unless we deal with the biopolitical arguments presented and resort to a technical and structural defence.
