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.

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.

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.

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.

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)

Bringing together evolutionary biology, psychology, and philosophy, Henry Plotkin presents a new science of knowledge, one that traces an unbreakable link between instinct and our ability to know.

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.

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.

Abstract: The optimum definition of the term "genocide" has been hotly contested almost since the term was coined. Definitional boundaries determine which acts are covered and excluded and thus to a great extent which cases will benefit from international attention, intervention, prosecution, and reparation. The extensive legal, political, and scholarly discussions prior to this article have typically (1) assumed "genocide" to be a fixed social object and attempted to define it as precisely as possible or (2) assumed the need for (...) a fixed convention and sought to stipulate the range of events that should be denoted by the term. Even if its meaning is a matter of convention, however, "genocide" is not a fixed object but varies by context and evolves in methods and forms over time. In fact, as relevant laws, legal interpretations, and political commitments develop, so do would-be perpetrators modify what genocide is in order to avoid political and legal consequences. This article advances an approach to a definition of "genocide" that allows even legal definitions to keep pace with this evolutionary process. (shrink)

The rapid emergence of digital media has created both new economic opportunities and new risks for authors, publishers, and users in regards to intellectual property. There is a theoretical conflict raging between those who believe "information should be free" and those attempting to protect intellectual property through surveillance and control of access. The Intellectual Commons works to develop a theory of intellectual property that is based on a theory of natural rights that assumes the existence of a "natural world" of (...) intellectual resources.

Benjamin Constant (1767–1830) is the most important French liberal that most casual liberals have never heard of. Everyone knows something about Montesquieu because checks and balances and the separation of powers are household terms. Tocqueville’s Democracy in America and The Old Regime and the Revolution are both established classics. But Constant is largely terra incognita even for those with a university degree—to their loss.

: Once cast aside as of no value, Charles S. Peirce manuscript 1570 "The First of Six Lessons . . ." and its context, provides uniquely valuable access to Peirce's religious practice (as distinct from his theology). Chronically unemployed, Peirce seized an opportunity to put in a bid for a vacant post in elocution at the Episcopal Church's major (and only "official") theological seminary, The General Theological Seminary in New York City. Peirce had on occasion appealed to nearby members of (...) the Episcopalian hierarchy seeking patronage for his scholarly work—to no avail. In this case, however, he was encouraged and aided by the current scholarly vicar of his own parish. The incumbent had pursued advanced education abroad and was also active in the seminary's affairs. And, of course, Peirce was confident about his expertise in elocution, which "General's" Dean claimed as well. Both the contextual narrative and the substantive theological content of his "lesson" are a rich resource for insights into the much vexed (if too often muddled) question of his lifelong commitment to a faith stemming from his earlier conversion to trinitarianism.

Beginning from the standpoint that technologically mediated education is widely prescribed for developing countries, the author first probes the nature, meaning, and impact of this agenda through its economic and political context. He argues that this context produces and shapes the rush to technology. He then examines the notion of education and the nature of the claimed technological mediation of this process, concluding that the constraints of technological mediation, and its destructive impact on teaching, show its inability to provide for (...) adequate educational development (which is necessarily grounded in a concrete human relationship in a real—not virtual—dynamic social and cultural context). He closes with recommendations for a critical rather than a wholesale adoption of technology and encourages resistance to the present press for mindless adoption. (shrink)
