An in-depth look at the science of ancient Greece, this volume examines the influence of antique philosophy on 17th-century thought. Additional topics embrace many elements of modern physics: the empirical basis of quantum mechanics, wave-particle duality and the uncertainty principle, and the action-at-a-distance theory of Wheeler and Feynman. 1961 edition.

The argument from analogy is examined from the standpoint of Carnap's confirmation theory. Carnap's own discussion of analogy in relation to his c*— function is restricted to cases where the analogues are known to be similar, but not known to be different in any respect. It has been argued by the author in a previous work,, and by P. Achinstein, that typical analogy arguments involve known differences between the analogues as well as similarities. Achinstein shows that for such arguments none (...) of Carnap's Δ— system of conflrmation functions gives satisfactory values, and it is further shown in the present paper that for these arguments the confirmation never rises above its initial value, irrespective of evidence drown from an analogue. it is argued that even if inductive arguments are to be applicable to the real world, they must in principle be capable of taking into account known differences between the instances of an inductive generalization. Hence Carnap's Δ— system is inadequate as an explication of both induction and analogy.Three conditions are stated as necessary for any confirmation theory which gives a satisfactory explication of analogical inference:I. If two individuals a and b are known to agree in certain properties and differ in others, and if in addition a has a further property, then the confirmation of the hypothesis that b also has this property is greater than its initial confirmation, at least if the weight of the similarities is sufficiently great compared with the weight of the differences.II. The confirmation‐value increases or decreases with the weight of the similarities between the analogues compared with the weight of their differences.III. The confirmation that b has a certain property is greater if a has that property than if a does not have it.The Δ— system sastisfles none of these conditions. Carnap and Stegmüller have now, however, presented a new anxiom system for confirmation functions. the — system, Which is introduced primarily to deal with languages whose primitive predicates fall into families such that each individual can only be qualified by one predicate of each family. They construct a c‐ function which, as well as dealing with a language having two families of such predicates, also depends, unlike the functions in the Δ— system, on similarities between otherwise different individuals. The system is not developed far enough in this Appendix to enable the authors to discuss the confirmation in analogy arguments satisfying conditions I — III above, but it is shown in the present paper that, with a simple generalization of the measure‐function defined by Carnap and Stegmüller, and in the simplest non‐trivial case, condition I — III are all satisfied, indeed a stronger form of condition I is satisfied, in which no known similarity of the analogues is postulated.Finally it is remarked that Carnap and Stegmüller's method of introducing their Δ— system is extremely arbitrary and ad hoc, and an alternative method of introducing is suggested. Bearing in mind the fundamental nature of the argument from analogy in all application of induction to the real world, it is suggesetd that the fundamental inductive inference needing explication is not the inference of‘P1b, from ‘P,1a, but the analogical infeence of‘P2b, from‘P1P2a.P1b,. It is posinitial confirmation of‘P2b, and the confirmation of‘P2b, given‘P2a” and that the later two confirmation‐values are equivalent to those in the Δ— system. It is then shown that Carnap and Stegmüller's new measure‐function follows from their axiom system together with these postulates. Thus some of the arbitrariness of the — system is removed by general considérations regarding inductive and analogical inference. (shrink)

In this book, Michael Arbib, a researcher in artificial intelligence and brain theory, joins forces with Mary Hesse, a philosopher of science, to present an integrated account of how humans 'construct' reality through interaction with the social and physical world around them. The book is a major expansion of the Gifford Lectures delivered by the authors at the University of Edinburgh in the autumn of 1983. The authors reconcile a theory of the individual's construction of reality as a network of (...) schemas 'in the head' with an account of the social construction of language, science, ideology and religion to provide an integrated schema-theoretic view of human knowledge. The authors still find scope for lively debate, particularly in their discussion of free will and of the reality of God. The book integrates an accessible exposition of background information with a cumulative marshalling of evidence to address fundamental questions concerning human action in the world and the nature of ultimate reality.

Ethics is central to scientific and engineering research and practice, but a key challenge for promoting students’ ethical formation involves enhancing faculty members’ ability and confidence in embedding positive ethical learning experiences into their curriculums. To this end, this paper explores changes in faculty members’ approaches to and perceptions of ethics education following their participation in a multi-year interdisciplinary faculty learning community (FLC). We conducted and thematically analyzed semi-structured interviews with 11 participants following the second year of the FLC. Qualitative (...) themes suggested that, following two years of FLC participation, faculty members (1) were better able to articulate their conceptualizations of ethics; (2) became cognizant of how personal experiences, views, and beliefs informed how they introduced ethics into their curriculum; and (3) developed and lived instructional principles that guided their ethics teaching. Results thus suggested that faculty members benefitted from exploring, discussing, and teaching ethics, which (in turn) enabled them to see new opportunities and become confident in integrating ethics into their courses in meaningful ways that aligned with their scholarly identities. Taken together, these data suggest faculty became agents of change for designing, implementing, and refining ethics-related instructional efforts in STEM. This work can guide others interested in designing faculty learning communities to promote instructional skill development, faculty members’ awareness of their ethical values, and their ability and agency to design and integrate ethics learning activities alongside departmental peers in an intentional and continuous manner.

I am grateful to Brendan Minogue for his careful and detailed discussion of the concept of “intensional reference” as it appears in my book The Structure of Scientific Inference. He concludes that my account contains some important inconsistencies that vitiate my attempt to reconcile the idea of cumulative acquisition of scientific knowledge with radically changing theories. He rightly sees that this attempt depends crucially on the account of translatability between theories, and this in turn upon the notion of “identity of (...) intensional reference.” This means that the attempt fails if there are inconsistencies in the concept of IR. Since Minogue's careful analysis nevertheless contains some misunderstandings, I must plead guilty to a number of unclarities, but I do not believe there are basic inconsistencies. Let me try again.

Hempel's qualitative criteria of converse consequence and special consequence for confirmation are examined, and the resulting paradoxes traced to the general intransitivity of confirmation. Adopting a probabilistic measure of confirmation, a limiting form of transitivity of confirmation from evidence to predictions is derived, and it is shown to what extent its application depends on prior probability judgments. In arguments involving this kind of transitivity therefore there is no necessary "convergence of opinion" in the sense claimed by some personalists. The conditions (...) of application of the limiting transitivity theorem are most perspicuously described in terms of De Finetti's notion of exchangeability, which leads to a suggested revaluation of the function of theories in relation to confirmation and explanation.

Faced with what he saw as the danger to society in the ascendancy of natural science and decline in religion and morals, the great French sociologist Emile Durkheim sought the origins of both religion and science in their function in primitive societies as guarantors of social solidarity. In contrast to Frazer, Tylor, and other early anthropologists, he looked for the internal intelligibility of myth and ritual in social terms, rather than regarding them just as failed attempts to state objective truths (...) about the natural world of the same kind as those later arrived at by natural science. One does not have to accept Durkheim's ultimately atheistic identification of God with Society, nor the politically authoritarian consequences which have some-times been held to follow from this identification, to see that Durkheim has raised a set of issues of crucial importance for a discussion of science and the myths and doctrines of religion. For what he has done is to reintroduce a third factor into the perennial and by now rather frustrating dichotomy between science and religion, namely society and the sciences of man. It is some consequences of this approach that I want to explore in this paper. (shrink)

As in the case of great books in all branches of philosophy, Pierre Duhem's Le Théorie Physique , first published in 1906, can be looked to as the progenitor of many different and even conflicting currents in subsequent philosophy of science. On a superficial reading, it seems to be an expression of what later came to be called deductivist and instrumentalist analyses of scientific theory. Duhem's very definition of physical theory, put forward early in the book, is the quintessence of (...) instrumentalism: A physical theory is not an explanation. It is a system of mathematical propositions, deduced from a small number of principles, which aim to represent as simply, as completely, and as exactly as possible a set of experimental laws [p. 19].

Logic, Methodology, and the Philosophy of Science, the Proceedings of the 1960 International Congress at Stanford, is heavily weighted towards technical problems of logic, foundations of mathematics, and the special sciences, especially psychology, economic models, and structural linguistics, with little discussion of general problems of the philosophy of science. Problems about the idealization involved in the relation of theories to the world become problems about probabilistic models at various levels of abstraction ; induction becomes a problem in decision theory ; (...) language becomes the subject-matter of formalized syntactics, and so on. There is nothing in the least undesirable about these inquiries in a Philosophy of Science Congress, but there is a danger that, if they are not balanced by more informal discussions, real points of dispute are missed, or decided over-hastily in the brief preliminaries of formalization. The philosopher's job ought sometimes to be the more irritating one of returning to these points of dispute; a job which is well done in some of the contributions to this volume, but one could wish to find it being done in more. In what follows I shall have to restrict myself to commenting on only a handful of these more philosophical papers. (shrink)

In his paper “William Whewell on the Consilience of Inductions” Professor Laudan has suggested that Whewell’s use of “consilience of inductions” is not the same as mine in my paper of that title. Suppose we have a theory T which entails three empirical laws L1, L2, L3. L1 is supposed already confirmed by direct evidence of its instances, but we have as yet no direct evidence for L2 or for L3. Then Laudan distinguishes two problems: Whewell’s problem: T is suggested (...) to explain L1 and is supported by L1; how much is our confidence in T increased if it also predicts L2, and L2 is subsequently directly confirmed? My problem: T is suggested to explain L1 and is supported by L1; T also entails L3; how much is our confidence that L3 will turn out a correct prediction increased by the fact that T entails it?
