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.

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.

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)

Paradise Understood: New Philosophical Essays about Heaven systematically investigates heaven, or paradise, as conceived within theistic religious traditions such as Rabbinic Judaism, Christianity, and Islam. It considers a variety of topics concerning what life in paradise would, could, or will be like for human persons. The collection offers novel approaches to questions about heaven of perennial philosophical interest, and breaks new ground by expanding the range of questions about heaven that philosophers have considered. 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)

So much for the Aesthetic. We can now proceed to the Analytic, the philosophical importance of which is much greater. Kant's main contentions in this part of his work can be summed up in; two propositions: human understanding contains certain a priori concepts, and on these are based certain non-empirical principles; these concepts are only general concepts of a phenomenal object, and therefore the principles in question are only prescriptive to sense-experience. As has already been said, interest in the first (...) proposition has distracted attention from the fact that the important thing Kant has to say is contained in the second. (shrink)

Presentists claim that only presently existing objects exist. One version of presentism is ersatzer presentism, according to which times are a kind of abstract object. Such a view is appealing because it affords the presentist an answer to the grounding objection—a potentially lethal objection to presentism. Despite this advantage, available versions of ersatzer presentism suffer from a heretofore unappreciated shortcoming: they cannot account for the truth of certain counterfactual claims about the past. We argue for this claim by considering two (...) views representative of ersatzer presentism—those of Thomas Crisp and Craig Bourne. After presenting our arguments against their views, we defend two crucial assumptions in those arguments. Finally, we offer a novel version of ersatzer presentism that appropriates the metaphysics of constitution in order to avoid the difficulty that current ersatzer presentist views face. (shrink)

Henri Bergson (1859-1941) is one of the truly great philosophers of the Modernist period, and there is currently a major renaissance of interest in his unduly neglected texts and ideas amongst philosophers, literary theorists, and social theorists. Mind-Energy is a collection of essays and lectures from the period 1901-13 and has long been out of print. It features essays on life and consciousness, soul and body, mind and brain, and on dreams, memory and the phenomenon of false recognition; the insights (...) Bergson develops in them remain highly pertinent to contemporary work in the philosophy of mind. (shrink)

Cet ouvrage n'est ni un commentaire ni une explication d'obedience historiciste ou deterministe. Par questionnement, lecture et interpretation, l'auteur a voulu produire une semantique philosophique. La doctrine des idees est ainsi reexaminee a la convergence des problemes du langage, de la science et de la cite (logos, episteme, polis). Elle ne peut plus des lors etre interpretee sous l'hypothese de l' idealisme. Elle se manifeste comme une serie de questions de sens ou s'indique une philosophie de la raison. Partout ou (...) le logos nous porte, c'est la qu'il faut aller, tel en serait le mot d'ordre, mais avec la precision qu'a l'articulation du mythique et du theorique, du tragique et du philosohique, et plus profondement de la deraison et du logos, le rationalisme platonicien n'est fait que de raison.

Henry Home (1696-1782) has been called "perhaps the most complete 'Enlightenment man' among the eighteenth-century Scottish thinkers." Kinsman and friend of David Hume, mentor and patron of Adam Smith, John Millar, and Thomas Reid, he was a key figure in that circle of luminaries. He read law, was called to the bar in 1723, was raised to the Bench of the Court of Session in 1752, with the title Lord Kames (the name of his family estate), and joined the (...) High Court of the Justiciary in 1763. Publishing broadly in law, history, philosophy, and criticism, Kames made significant contributions to the Enlightenment's science of human nature. The Essays is commonly considered Kames's most important philosophical work. In the first part, he sets forth the principles and foundations of morality and justice, attacking Hume's moral skepticism and addressing the controversial issue of the freedom of human will. In the second part, Kames focuses on questions of metaphysics and epistemology to offer a natural theology in which the authority of the external senses is an important basis for belief in the Deity. The text of this volume is based on the third edition of 1779, while the appendix presents substantial variant readings in the first and second editions. (shrink)

Yarkoni's analysis clearly articulates a number of concerns limiting the generalizability and explanatory power of psychological findings, many of which are compounded in infancy research. ManyBabies addresses these concerns via a radically collaborative, large-scale and open approach to research that is grounded in theory-building, committed to diversification, and focused on understanding sources of variation.

Cosmological arguments for the existence of God face a gap problem. This is the problem of convincingly arguing that their intermediate conclusions that some first cause or necessary being exists provide evidence for their main conclusion that God exists. This paper develops a simple and innovative approach to solving this problem, applicable to many cosmological arguments. According to the proposal, the best explanation for why the necessary being is found to have necessary existence is that it is a perfect being. (...) Since a perfect being would be God, the intermediate conclusions of the relevant cosmological arguments provide abductive evidence for their main conclusions. (shrink)

This book argues that Augustine assimilated the Stoic theory of perception and mental language (lekta/dicibilia), and that this epistemology underlies his accounts of motivation, affectivity, therapy for the passions, and moral progress. Byers elucidates seminal passages which have long puzzled commentators, such as Confessions 8, City of God 9 and 14, Replies to Simplicianus 1, and obscure sections of the later ‘anti-Pelagian’ works. Tracking the Stoic terminology, Byers analyzes Augustine’s engagement with Cicero, Seneca, Ambrose, Jerome, Origen, and Philo of Alexandria, (...) demonstrating that Augustine appropriated Stoicism with greater sophistication than other religious writers. She also shows how he moved beyond the Stoics by enriching Stoic cognitivism with Platonic motivational theory, arguing that Augustine created a coherent synthesis. This newly discovered Augustinian moral psychology has elements that contemporary philosophers and psychologists have identified as important. (shrink)

Explanationism holds that a person's evidence supports a proposition just in case that proposition is part of the best available explanation for the person's evidence. I argue that explanationism faces a serious difficulty when it comes to justified beliefs about the future. Often, one's evidence supports some proposition about the future but that proposition is not part of the best available explanation for one's evidence. Attempts to defend explanationism against this charge are unattractive. Moving to a modified better contrastive explanation (...) account will help with these cases, but it will face other difficulties. (shrink)
