According to some, taking moral testimony is a potentially decent way to exercise one's moral agency. According to others, it amounts to a failure to live up to minimal standards of moral worth. What's the issue? Is it conceptual or empirical? Is it epistemological or moral? Is there a ‘puzzle’ of moral testimony; or are there many, or none? I argue that there is no distinctive puzzle of moral testimony. The question of its legitimacy is as much a moral or political as an epistemological question. Its answer is as much a matter of contingent empirical fact as a matter of a priori necessity. In the background is a mixture of normative and descriptive issues, including the value of autonomy, the nature of legitimate authority, and who to trust

The paper examines the plausibility of analytical dispositionalism about practical reason, according to which the following claims are conceptual truths about common sense ethical discourse: i) Ethics: agents have reasons to act in some ways rather than others, and ii) Metaphysical Modesty: there is no such thing as a response independent normative reality. By elucidating two uncontroversial assumptions which are fundamental to the common sense commitment to ethics, I argue that common sense ethical discourse is most plausibly construed as committed to the denial of metaphysical modesty, and thereby as committed to the existence of a response independent normative reality.

Bart Streumer argues that it is not possible for us to believe the error theory, where by ‘error theory’ he means the claim that our normative beliefs are committed to the existence of normative properties even though such properties do not exist. In this paper, we argue that it is indeed possible to believe the error theory. First, we suggest a critical improvement to Streumer’s argument. As it stands, one crucial premise of that argument—that we cannot have a belief while believing that there is no reason to have it—is implausibly strong. We argue that for his purposes, Streumer’s argument only requires a weaker premise, namely that we cannot rationally have a belief while believing that there is no reason to have it. Secondly, we go on to refute the improved argument. Even in its weaker form, Streumer’s argument is either invalid or the crucial premise should be rejected.

Book synopsis: Assisted reproduction challenges and reinforces traditional understandings of family, kinship and identity. Sperm, egg and embryo donation and surrogacy raise questions about relatedness for parents, children and others involved in creating and raising a child. How socially, morally or psychologically significant is a genetic link between a donor-conceived child and their donor? What should children born through assisted reproduction be told about their origins? Does it matter if a parent is genetically unrelated to their child? How do experiences differ for men and women using collaborative reproduction in heterosexual or same-sex couples, single parent families or co-parenting arrangements? What impact does the wider cultural, socio-legal and regulatory context have? In this multidisciplinary book, an international team of academics and clinicians bring together new empirical research and social science, legal and bioethical perspectives to explore the key issue of relatedness in assisted reproduction.

The Cambridge philosopher Frank Ramsey died tragically young, but had already established himself as one of the most brilliant minds of the twentieth century. Besides groundbreaking work in philosophy, particularly in logic, language, and metaphysics, he created modern decision theory and made substantial contributions to mathematics and economics. In these original essays, written to commemorate the centenary of Ramsey's birth, a distinguished international team of contributors offer fresh perspectives on his work and show how relevant it is to present-day concerns.Each of the ten essays addresses fundamental and contentious issues, including success semantics, propositions, infinity, conditionals, conceptual analysis, decision theory, and intergenerational justice. They also shed light on the intellectual context in which Ramsey developed his thought, including his relationship with such leading thinkers as John Maynard Keynes, Bertrand Russell, and Ludwig Wittgenstein. The volume will be indispensable reading for anyone interested in the recent history of philosophy and economics, as well as for practitioners and students of logic, metaphysics, philosophy of mathematics, philosophy of science, philosophy of mind, decision theory, and welfare economics.

The aim of this paper is to identify and evaluate some of the most serious objections to the view that morality is a social construction. Among the objections considered are the claims that this view is incoherent; that it over-generates moral truths; that it under-generates moral truths; that it fails to capture the modal status of some moral truths; and that it fails to account for the phenomenology of moral experience. In each case, the objections are found wanting. During the course of the paper, the social constructivist view is critically compared with a range of other metaethical views, including moral realism and other forms of constructivism.

The Trolley Problem is one of the most intensively discussed and controversial puzzles in contemporary moral philosophy. Over the last half-century, it has also become something of a cultural phenomenon, having been the subject of scientific experiments, online polls, television programs, computer games, and several popular books. This volume offers newly written chapters on a range of topics including the formulation of the Trolley Problem and its standard variations; the evaluation of different forms of moral theory; the neuroscience and social psychology of moral behavior; and the application of thought experiments to moral dilemmas in real life. The chapters are written by leading experts on moral theory, applied philosophy, neuroscience, and social psychology, and include several authors who have set the terms of the ongoing debates. The volume will be valuable for students and scholars working on any aspect of the Trolley Problem and its intellectual significance.
