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.

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.

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.

This volume provides an integrated and wide-ranging set of primary-source readings on the relationship between moral values and economic activity, as articulated by some of the leading figures in Western civilization.

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)

This paper aims to do two things. First, it describes the place that Adam Smith actually occupies in current research occurring at the boundaries of new interdisciplinary social-science fields such as evolutionary anthropology, evolutionary psychology, neuro-economics and behavioral economics. Second, it suggests a way in which Smith's place in the debates with which these subjects are concerned may be more properly defined and conceptualized. Specifically, the paper focuses on the controversial new theory of strong reciprocity, and on the reputation effects (...) that its critics think that theory neglects. (shrink)
