This paper defends a realist interpretation of theories and a modest realism concerning the existence of quantities as providing the best account both of the logic of quantity concepts and of scientific measurement practices. Various operationist analyses of measurement are shown to be inadequate accounts of measurement practices used by scientists. We argue, furthermore, that appeals to implicit definitions to provide meaning for theoretical terms over and above operational definitions fail because implicit definitions cannot generate the requisite descriptive content. The (...) special case of establishing a temperature scale is examined to show that nonrealist accounts fail to provide insight into the theoretical connections that scientific laws postulate to hold among quantities.

Central to many issues surrounding reduction in science is the relation between a physical system and its components. In this article we examine how thermodynamic theory relates properties of whole systems to properties of their components. In order to keep the analysis general, we focus our study on universal properties like volume, heat capacity, energy and temperature. In the cases examined we find that scientific explanation requires appeal to properties of components that are spatially as extensive as the whole system. (...) We discuss some implications of our study for the purported paradigmatic reductions of heat and temperature to molecular motion. We conclude that while macro systems reduce ontologically to micro components, epistemologically the reduction of theoretical concepts in general fails. (shrink)

I characterize a notion of causal agency that is the causitive component of many transitive verbs. The agency of what I call substantial causes relates objects physically to systems with which they interact. Such agent causation does not reduce to conditionship relations, nor does it cease to play a role in scientific discourse. I argue, contrary to regularity theories, that causal claims do not in general depend for their sense on generalities nor do they entail the existence of laws. Clarification (...) of the relationships among substantial causes, causal processes, and explanatory conditions separates the analysis of causal connection from that of nomological connection. This clarification is then applied to a variety of issues in the analysis of causality. (shrink)

Intended both for undergraduate students and for general readers, this introduction to the philosophy of science uses case studies, anecdotes and personal comment to portray many heroes and villains from the field of science through the ages.

1. Introduction. Professor Nagel's account of the “cognitive status” of scientific theories has been attacked by P. K. Feyerabend [5] and M. B. Hesse [8] in terms of his alledgedly misguided distinction between experimental laws and theories. The difficulty lies, these critics agree, in Nagel's attempt to find a stable basis for scientific theories in an observational basis of experimental laws. Both Feyerabend and Hesse note the vacillation in Nagel's account of the stability of the meaning of experimental terms and (...) in his discussion of the status of observational as opposed to theoretical terms. They find Nagel too “positivistic” and see as a first step toward a more adequate account of scientific theories the abandonment of the theoretical-observational dichotomy as having more than a pragmatic significance. Nagel's discussion of the theoretical-observational dichotomy is, I agree, inadequate in certain respects. I shall, however, suggest a quite different remedy from those of Feyerabend and Hesse, one that depends neither on a phenomenalistic reduction of theoretical entities nor on a blurring of the theoretical-observational dichotomy.

For many laws causal asymmetries in dependencies among the variables are not reflected in functional relations of the law equation. In the case of the simple pendulum law, why can we cite the length to explain the period but not the period to explain the length? After surveying attempts to explain the asymmetries, I propose a new account based on an analysis of the relation of causes and laws. This analysis is used to criticize the very notion of causal laws (...) and to clarify the role of ceteris paribus clauses in interpreting scientific laws. (shrink)

How are causes and laws related? Some attempt to analyze causal relations in terms of laws, others view causal explanation as quite distinct from explanation using laws. My analysis of the relations between causes and laws focuses on cases such as the simple pendulum law where asymmetries in causal relations between quantities are not reflected in the functional dependencies in the law equations. The asymmetry puzzle has elicited a variety of accounts which reflect quite different views on the relation between (...) causes and laws and their roles in scientific explanation. Finding none of the usual accounts satisfying, I offer an explication based on some distinctions in the analysis of the relevant causes that are not commonly heeded. I criticize the very notion of causal law and examine some implications of my account for ceteris paribus problems which arise in attempts to give realist interpretations of scientific theories.

Fitness in the sense of actual rate of increase of genotypes, commonly used in population genetics, is contrasted with fitness in the ordinary sense (and Darwin's) of adaptedness of organisms. Fitness as actual reproductive success is interpreted as a function of variables representing intrinsic adaptive capacities and environmental properties. Adaptive capacities causally contribute to fitness as actual reproductive success which in turn, as relative increase of genotypes, determines evolutionary change. The propensity interpretation of fitness is shown not to play a (...) role in evolutionary explanation. (shrink)

Recent attempts to clarify the fitness in evolutionary theory as a propensity (Brandon 1978; Brandon and Beatty 1984; Burian 1983; Mills and Beatty 1979; Sober 1984a, 1984b) or as a primitive theoretical term (Rosenberg 1983, 1985; Williams 1970, Williams and Rosenberg 1985) all miss the mark in clarifying the empirical content and explanatory power of natural selection theory.I shall argue that the crucial distinction missing in these accounts is between the sense of fitness common in population genetics as actual relative (...) rate of increase of genotypes and fitness in the more ordinary sense--and Darwin’s--of adaptedness of organisms. The relation between these senses of ‘fitness’ is that fitness as actual reproduction success depends on, is a function of, variables representing adaptive capacities and environmental properties. (shrink)

Recent philosophical discussions have failed to clarify the roles of the concept fitness in evolutionary theory. Neither the propensity interpretation of fitness nor the construal of fitness as a primitive theoretical term succeed in explicating the empirical content and explanatory power of the theory of natural selection. By appealing to the structure of simple mathematical models of natural selection, we separate out different contrasts which have tended to confuse discussions of fitness: the distinction between what fitness is defined as versus (...) what fitness is a function of, the contrast between adaptedness as an overall property of organisms and specific adaptive capacities, the distinction between actual and potential reproductive success, the role of chance versus systematic causal relations, fitness as applied to organisms as opposed to fitness applied to genotype classes, heritable adaptive capacities of genotypes as opposed to relations between genotypes and the environment. We show how failure to distinguish and properly interrelate these different aspects of “fitness” adds confusion to a number of already complex issues concerning evolutionary theory. On the basis of our discussion of these different aspects of “fitness”, we propose a terminology which makes the necessary distinctions. A central result of our analysis is that the concept of fitness as the overall adaptedness of organisms does not enter into the causal structure of evolutionary explanation, at least to the extent that this structure is represented in the mathematical models of natural selection.

There is more to science than Aristotle’s natural desire to know. The major achievement of this book lies in presenting this idea through the study of the lives of various scientists.

Why absolute certainty is impossible in science In today's unpredictable and chaotic world, we look to science to provide certainty and answers—and often blame it when things go wrong. The Blind Spot reveals why our faith in scientific certainty is a dangerous illusion, and how only by embracing science's inherent ambiguities and paradoxes can we truly appreciate its beauty and harness its potential. Crackling with insights into our most perplexing contemporary dilemmas, from climate change to the global financial meltdown, this (...) book challenges our most sacredly held beliefs about science, technology, and progress. At the same time, it shows how the secret to better science can be found where we least expect it—in the uncertain, the ambiguous, and the inevitably unpredictable. William Byers explains why the subjective element in scientific inquiry is in fact what makes it so dynamic, and deftly balances the need for certainty and rigor in science with the equally important need for creativity, freedom, and downright wonder. Drawing on an array of fascinating examples—from Wall Street's overreliance on algorithms to provide certainty in uncertain markets, to undecidable problems in mathematics and computer science, to Georg Cantor's paradoxical but true assertion about infinity—Byers demonstrates how we can and must learn from the existence of blind spots in our scientific and mathematical understanding. The Blind Spot offers an entirely new way of thinking about science, one that highlights its strengths and limitations, its unrealized promise, and, above all, its unavoidable ambiguity. It also points to a more sophisticated approach to the most intractable problems of our time. (shrink)

Augustine made a significant contribution to the history of philosophical accounts of affectivity which scholars have not yet noticed. He resolved a problem with the Stoic theory as it was known to him: the question of the cognitive cause of "preliminary passions" ( propatheiai ), reflex-like affective reactions which must be immediately controlled if a morally bad emotion is to be avoided. He identified this cognitive cause as momentary doubt, as I demonstrate by citing passages from sermons spanning twenty-seven years (...) in which Augustine consistently used a particular set of scriptural images and phrases as precise analogies for mental and affective states.

There is more than one way to think. Most people are familiar with the systematic, rule-based thinking that one finds in a mathematical proof or a computer program. But such thinking does not produce breakthroughs in mathematics and science nor is it the kind of thinking that results in significant learning. Deep thinking is a different and more basic way of using the mind. It results in the discontinuous "aha!" experience, which is the essence of creativity. It is at the (...) heart of every paradigm shift or reframing of a problematic situation. The identification of deep thinking as the default state of the mind has the potential to reframe our current approach to technological change, education, and the nature of mathematics and science. For example, there is an unbridgeable gap between deep thinking and computer simulations of thinking. Many people suspect that such a gap exists, but find it difficult to make this intuition precise. This book identifies the way in which the authentic intelligence of deep thinking differs from the artificial intelligence of "big data" and "analytics." Deep thinking is the essential ingredient in every significant learning experience, which leads to a new way to think about education. It is also essential to the construction of conceptual systems that are at the heart of mathematics and science, and of the technologies that shape the modern world. Deep thinking can be found whenever one conceptual system morphs into another. The sources of this study include the cognitive development of numbers in children, neuropsychology, the study of creativity, and the historical development of mathematics and science. The approach is unusual and original. It comes out of the author's lengthy experience as a mathematician, teacher, and writer of books about mathematics and science, such as How Mathematicians Think: Using Ambiguity, Contradiction, and Paradox to Create Mathematics and The Blind Spot: Science and the Crisis of Uncertainty.

The contributors wrestle with questions about human (...) life in paradise that span the spectrum of the major subfields of philosophical enquiry. By employing both historical and contemporary philosophical resources, the volume makes a pioneering contribution toward answering pressing questions about human life in paradise. It will serve as a platform for future research, reinvigorating philosophical investigation into these neglected topics within philosophy of religion. (shrink)

The University of Pittsburgh policy for procuring organs from non-heart-beating cadaver donors recognizes the potential for conflicts of interest between caring for a "hopelessly ill" patient who has forgone life-sustaining treatment and caring for a potential organ donor. The policy calls for a separation between those medical personnel who care for the gravely ill patient and those involved with the care of transplant recipients. While such a separation is possible in theory, it is difficult or impossible to attain in practice. (...) However, such a separation of duties would be unnecessary if an arbitrator were appointed to monitor the proceedings as they take place on a case-by-case basis. In this way, the biases—real or potential—of the individuals involved could be identified, and the harmful effects of the unavoidable conflicts of interest could be minimized. (shrink)

One of the major works of an important modem philosopher, Matter and Memory investigates the autonomous yet interconnected planes formed by matter and perception on the one hand and memory and time on the other. Henry Bergson (1859-1941) was awarded the Nobel Prize in 1927. His works include Time and Free Will, An Introduction to Metaphysics, Creative Evolution, and The Creative Mind.

Henri Meschonnic was a linguist, poet, translator of the Bible and one of the most original French thinkers of his generation. He strove throughout his career to reform the understanding of language and all that depends on it. His work has had a shaping influence on a generation of scholars and here, for the first time, a selection of these are made available in English for a new generation of linguists and philosophers of language. This Reader, featuring fourteen texts covering (...) the core concepts and topics of Meschonnic's theory, will enrich, enhance and challenge your understanding of language. It explores his key ideas on poetics, the poem, rhythm, discourse and his critique of the sign. Meschonnic's vast oeuvre was continuously preoccupied with the question of a poetics of society; he constantly connected the theory of language to its practice in various fields and interrogated what that means for society. In exploring this fundamental question, this book is central to the study and philosophy of language, with rich repercussions in fields such as translation studies, poetics and literary studies, and in redefining notions such as rhythm, modernity, the poem and the subject.

One of the most influential of the Victorian philosophers, Henry Sidgwick also made important contributions to fields such as economics, political theory and classics. A proponent of the utilitarianism of Jeremy Bentham and John Stuart Mill, which he analysed in his classic work The Methods of Ethics, he later turned to the practical side of politics in this work, published in 1891. His aim was to have a 'rational discussion of political questions in modern states', and he offers a (...) thorough examination of Victorian politics, beginning with a discussion of political theory before moving on to more concrete matters such as property and law. The later chapters discuss the function of government through themes such as procedural matters, international affairs, war, political parties, and public participation, giving a comprehensive account of both ideas about and the functioning of late-nineteenth-century government.

There is growing interest in machine ethics in the question of whether and under what circumstances an artificial intelligence would deserve moral consideration. This paper explores a particular type of moral status that the author terms psychological moral patiency, focusing on the epistemological question of what sort of evidence might lead us to reasonably conclude that a given artificial system qualified as having this status. The paper surveys five possible criteria that might be applied: intuitive judgments, assessments of intelligence, the (...) presence of desires and autonomous behavior, evidence of sentience, and behavioral equivalence. The author suggests that despite its limitations, the latter approach offers the best way forward, and defends a variant of that, termed the cognitive equivalence strategy. In short, this holds that an artificial system should be considered a psychological moral patient to the extent that it possesses cognitive mechanisms shared with other beings such as nonhuman animals whom we also consider to be psychological moral patients. -/- .
