Epistemic decision theory (EDT) employs the mathematical tools of rational choice theory to justify epistemic norms, including probabilism, conditionalization, and the Principal Principle, among others. Practitioners of EDT endorse two theses: (1) epistemic value is distinct from subjective preference, and (2) belief and epistemic value can be numerically quantified. We argue the first thesis, which we call epistemic puritanism, undermines the second.

Based on the "Guide to the Human Fertilisation and Embryology Act 1990", this volume reviews the regulation of assisted conception including complex moral issues such as abortion, embryo research and cloning.

This book provides a variety of diverse perspectives related to the ethics of anger, some more analytical in nature, others focused on practical issues, some in defense of anger, and others arguing against its necessity. This book is an essential resource for scholars who want to reflect critically on the place of anger in contemporary life.

Evans attempted to develop a classical unified field theory of gravitation and electromagnetism on the background of a spacetime obeying a Riemann-Cartan geometry. In an accompanying paper I, we analyzed this theory and summarized it in nine equations. We now propose a variational principle for a theory that implements some of the ideas that have been (imprecisely) indicated by Evans and show that it yields two field equations. The second field equation is algebraic in the torsion and we can resolve (...) it with respect to the torsion. It turns out that for all physical cases the torsion vanishes and the first field equation, together with Evans’ unified field theory, collapses to an ordinary Einstein equation. (shrink)

In accordance with an old suggestion of Asher Peres (1962), we consider the electromagnetic field as fundamental and the metric as a subsidiary field. In following up this thought, we formulate Maxwell’s theory in a diffeomorphism invariant and metric-independent way. The electromagnetic field is then given in terms of the excitation $H = ({\cal H}, {\cal D})$ and the field strength F = (E,B). Additionally, a local and linear “spacetime relation” is assumed between H and F, namely H ~ κ (...) F, with the constitutive tensor κ. The propagation is studied of electromagnetic wave fronts (surfaces of discontinuity) with a method of Hadamard. We find a generalized Fresnel equation that is quartic in the wave covector of the wave front. We discuss under which conditions the waves propagate along the light cone. Thereby we derive the metric of spacetime, up to a conformal factor, by purely electromagnetic methods. (shrink)

It includes such celebrities of the twentieth century as Pearl Buck, Norman Cousins, Margaret Mead, James Michener, Jackie Robinson, and Harry Truman. With an introduction by Edward R. Murrow and a foreword by Dan Gediman, executive producer of the contemporary This I Believe radio broadcasts, heard weekly on public radio.

Crash Course in Logic is a booklet designed to introduce basic principles of logic and critical thinking to students so they can better express their ideas. Many high school and college students have trouble constructing theoretical arguments and writing clearly because they are not acquainted with the forms of reasoning that are presented in this booklet. Intended as a supplement to other instructional material for a variety of courses, this booklet will guide students through a mini-course on logic that includes (...) many examples and exercises. With knowledge of the basic forms of reasoning, students will have the tools necessary to solve problems and evaluate arguments as well as articulate their own ideas and insights clearly. Crash Course in Logic will be of great value to teachers of any subject who are searching for an accessible way to teach critical thinking and reasoning to their students. (shrink)

The natural epistemology of W. V. Quine has not been well understood. Critics argue that Quine's scientific approach to epistemology is circular and fails to be normative, yet these criticisms tend to be based on the very presuppositions concerning language, theory, and epistemology that Quine is at pains to reject or alter. ;Quine's views on the meaningfulness of language use imply a breakdown in the dichotomy between language as a theoretically neutral instrument and theory as the commitment to some subset (...) of the sentences allowed by a language. This breakdown, and the view of language which drives it, result in Quine's doctrine that speaking a language involves substantial theoretical commitments, and that inquiry must begin from within some ongoing theory of the world. That is, our epistemic practices, including epistemology itself, must be globally circular. The traditionally fundamental norm of linear propositional support, which drives the circularity objection, is thus seen as based in a misconception of language and theory. This not only explains Quine's lack of concern with the circularity of his view, but also illuminates the fundamental motivation for his general naturalism. ;Natural epistemology cannot be normative in the traditional sense of providing an independent ground for science. However, having accepted the "terminal parameter" of prediction as the test of theory, normativity becomes a matter of describing which procedures best promote predictively successful theory. Thus, epistemic norms emerge from science as hypotheses concerning the effectiveness of various methods in promoting predictively successful theory. Not only can natural epistemology prescribe and proscribe various epistemic practices, it offers the promise of an explanatory understanding of the strengths and weaknesses of those practices. Based on this understanding, natural epistemology further involves the improvement of current practices and the development of new ones. Crucial to this reconception of epistemology is the reconception of the knower as an adaptive organism employing the language/theory complex as an adaptive tool for interacting with the environment. ;The naturalism/anti-naturalism debate is advanced by acknowledging the substantial theoretical commitments implicit in the traditional view, and by examining Quine's reconception of language, theory, and the human knowing subject.
