Richard Jeffrey is beyond dispute one of the most distinguished and influential philosophers working in the field of decision theory and the theory of knowledge. His work is distinctive in showing the interplay of epistemological concerns with probability and utility theory. Not only has he made use of standard probabilistic and decision theoretic tools to clarify concepts of evidential support and informed choice, he has also proposed significant modifications of the standard Bayesian position in order that it provide a (...) better fit with actual human experience. Probability logic is viewed not as a source of judgment but as a framework for explaining the implications of probabilistic judgments and their mutual compatability. This collection of essays spans a period of some 35 years and includes what have become some of the classic works in the literature. There is also one completely new piece, while in many instances Jeffrey includes afterthoughts on the older essays. (shrink)

One of our most brilliant evolutionary biologists, Richard Lewontin has also been a leading critic of those--scientists and non-scientists alike--who would misuse the science to which he has contributed so much. In The Triple Helix, Lewontin the scientist and Lewontin the critic come together to provide a concise, accessible account of what his work has taught him about biology and about its relevance to human affairs. In the process, he exposes some of the common and troubling misconceptions that misdirect (...) and stall our understanding of biology and evolution.The central message of this book is that we will never fully understand living things if we continue to think of genes, organisms, and environments as separate entities, each with its distinct role to play in the history and operation of organic processes. Here Lewontin shows that an organism is a unique consequence of both genes and environment, of both internal and external features. Rejecting the notion that genes determine the organism, which then adapts to the environment, he explains that organisms, influenced in their development by their circumstances, in turn create, modify, and choose the environment in which they live.The Triple Helix is vintage Lewontin: brilliant, eloquent, passionate, and deeply critical. But it is neither a manifesto for a radical new methodology nor a brief for a new theory. It is instead a primer on the complexity of biological processes, a reminder to all of us that living things are never as simple as they may seem. (shrink)

This book offers a concise survey of basic probability theory from a thoroughly subjective point of view whereby probability is a mode of judgment. Written by one of the greatest figures in the field of probability theory, the book is both a summation and synthesis of a lifetime of wrestling with these problems and issues. After an introduction to basic probability theory, there are chapters on scientific hypothesis-testing, on changing your mind in response to generally uncertain observations, on expectations of (...) the values of random variables, on de Finetti's dissolution of the so-called problem of induction, and on decision theory.

The 65th year of a scholar who has devoted 40 years to editing and elucidating Robert Grosseteste provides us with a collection of essays. Not surprisingly, they emanate from colleagues and former students of Richard Dales and reflect his interest, among other concerns, in Grosseteste's aspectus et affectus - range of vision and disposition of mind - those twin peaks with which the 13th century thinker helped to get Christian thought through Aristotle without mutual destruction.

"[This book] proposes new foundations for the Bayesian principle of rational action, and goes on to develop a new logic of desirability and probabtility."—Frederic Schick, _Journal of Philosophy_.

The metaphysics of early embryos is a hotly debated topic in contemporary bioethics and metaphysics. Many contemporary Aristotelians believe that a human being is present from the moment of conception. At the same time, certain findings in modern embryology about the formation of identical twins challenge this belief. It becomes much harder when these theories are taken into account to understand the continued identity over time of the embryo(s) given the twinning process. In this article, I will consider the philosophical (...) implications of two models of monozygotic twinning within an Aristotelian metaphysical schema one of which is the standard, or traditional, model. The other of which is a new model recently put forward by Herranz. For the sake of completeness, I will also consider the philosophical implications of chimeras for the Aristotelian position. I will explain how Aristotelians can understand the process of twinning while holding on to their belief that a human being is present from the moment of conception. Summary: I will argue that a human being is present from the moment of conception. I will argue for this on Aristotelian grounds, and I will then defend this claim from criticisms based on a number of findings in modern embryology. (shrink)

Following in the fashion of Stephen Jay Gould and Peter Medawar, one of the world's leading scientists examines how "pure science" is in fact shaped and guided by social and political needs and assumptions.

L'A. esamina in particolare il Commento grande al De anima. In primo luogo evidenzia l'insegnamento averroista in relazione al tema dell'intelletto e dell'individuo, in secondo luogo esamina alcune proposizioni relative all'immortalità dell'anima individuale, ma sottolinea la difficoltà di conciliare tali affermazioni di Averroè con la dottrina dell'intelletto. L'ultima parte dello studio propone un esame critico del recente studio di O.N. Mohammed, Averroes, Aristotle, and the Qur'an on Immortality «International Philosophical Quarterly» 33 37-55.

The classical rationalist philosophical tradition in Arabic reached its culmination in the writings of the twelfth-century Andalusian Averroes whose translated commentaries on Aristotle conveyed to the Latin West a rationalist approach which significantly challenged and affected theological and philosophical thinking in that Christian context. That methodology is shown at work in his Fasl al-Maqāl or Book of the Distinction of Discourse and the Establishment of the Relation of Religious Law and Philosophy (c. 1280), although the deeply philosophical character of his (...) subtle arguments has gone largely unappreciated. Here the philosophical foundations for his reasoning are exposed to reveal key elements of his rationalism. That approach is confirmed in his assertion in his later Long Commentary on the Metaphysics (c. 1290) that the highest worship of God is to be found first and foremost in the philosophical science of metaphysics rather than in the rituals of religion.

This book presents an introduction to Einstein's Theory of Relativity, which has become a necessary part of the theoretical equipment of every physicist. Even if we regard the Einstein theory of relativity merely as a convenient tool for the prediction of electromagnetic and optical phenomena, its importance to the physicist is very great, not only because its introduction greatly simplifies the deduction of many theorems which were already familiar in the older theories based on a stationary ether, but also because (...) it leads simply and directly to correct conclusions in the case of such experiments as those of Michelson and Morley, Trouton and Noble, and Kaufman and Bucherer, which can be made to agree with the idea of a stationary ether only by the introduction of complicated and ad hoc assumptions.

This paper examines the lawsuits brought by state and local government entities against prescription opioid producers and sellers. It examines their potential liability as well as some of the defenses they might raise. The paper also discusses multidistrict litigation and government lawsuits in state court. It concludes that litigation is not the best solution to the opioid crisis.

Rather than exploring faith as it relates to various political and historical controversies of the early modern period, Richard McCoy argues that "faith" in Shakespearean drama is best viewed as secular and poetic instead of an exclusively religious phenomenon.

Averroes asserts in his Long Commentary on the De Anima and in his Long Commentary on the Metaphysics that principles of the science of metaphysics are established in the science of psychology. In psychology, human intellectual understanding is found to require the separate agent intellect for the coming to be of knowledge. The analysis of human psychology establishes that intellect must exist and must be separate from the human being in existence. Moreover there exists potency in those things called intellect, (...) thanks to the argument for the existence of the material intellect. (shrink)
