This book examines a selection of philosophical issues in the context of specific episodes in the development of physical theories. Advances in science are presented against the historical and philosophical backgrounds in which they occurred. A major aim is to impress upon the reader the essential role that philosophical considerations have played in the actual practice of science. The book begins with some necessary introduction to the history of ancient and early modern science, with major emphasis being given to the two great watersheds of twentieth-century physics: relativity and, especially, quantum mechanics. At times the term 'construction' may seem more appropriate than 'discovery' for the way theories have developed and, especially in the later chapters, the question of the influence of historical, philosophical and even social factors on the very form and content of scientific theories is discussed.

A century after the birth of a father of peacekeeping, Ralph Bunche, UN peace operations have changed dramatically. The narrowly-defined, lightly-armed, strictly neutral operations of Bunche's day have become complex, multidisciplinary state-building operations. Then, peacekeeping buttressed essentially self-enforcing cease-fires; now, it aims to build the foundations of a self-renewing peace. These changes reflect six deeper shifts: the end of the Cold War; engagement with "internal" conflicts; rising regional organizations; North-South politics; the U.S.-UN relationship; and changes in peace operation mandates. These shifts create three future challenges: state building; reconceiving sovereignty; and the need for realism. The December 2004 High Level Panel Report proposes modest steps toward meeting those challenges, but the burden of realizing the proposed framework rests squarely with UN member states.

Seeing philosophy as conversation with a number of fruitful avenues of discourse, Rorty seems to be caught in limbo, unwilling to follow through or commit himself to any particular line of discourse for fear of closing himself off to alternative discourses. Choosing to adopt this particular attitude he still has made a choice: he has made a commitment to non-commitment, or as Ortega puts it, “decided not to decide.” Jose Ortega y Gasset, The Revolt of the Masses, trans. anonymously (New York: W.W. Norton & Company, 1957), p. 48. Such a commitment or decision is in no way neutral, for it attempts to enforce, by moral requirement, Richard Rorty, Philosophy and the Mirror of Nature, p. 394. a new vocabulary which views philosophy as conversation between speakers, with a whole range of obligations and implications included. Thus the Rortian alternative, like the alternatives he criticizes, plays the role “of the cultural overseer who knows everyone's common ground — the Platonic philosopherking who knows what everybody else is really doing whether they know it or not, because he knows about the ultimate context ... within which they are doing it.” Ibid., pp. 317–318. In fact, Rorty even refers to “conversation as the ultimate context” Ibid., p. 389. In assuming to know everyone's common ground, that every-one is participating in the conversation of humankind whether they realize it or not, Rorty seems to fall prey to a similar “self-deceptive ... absurdity of thinking that the vocabulary [he uses] ... has some privileged attachment to reality which makes it more than just a further set of descriptions.” Ibid., p. 361.One implication of such a position is that despite its holder's claims that he or she will at least attempt to incorporate abnormal discourses of all sorts, the conversationalist will not be able to consider seriously a number of types of discourse. If the edifying, hermeneutical philosopher were really “willing to pick up the jargon of the interlocutor rather than translating it into his own terms,” Ibid., p. 318. it would often be necessary to drop the notion of conversation as being a fundamental practice or moral obligation. Rorty is obviously unwilling to really pick up the jargon of the epistemologist and the meta-physician he criticizes, or of Nietzsche and Stirner, for each of these does not have contained within them, at least as a primary consideration, the continuing of the conversation of humankind. Because he imposes his vocabulary and descriptions on them - they are merely speakers in a conversation - he will see them as merely threads in a larger social fabric, he will be translating their “jargon” into his own, and thus will never be able to take their position seriously, never be prepared to adopt their position as his own. Being possessed by the notion of continuing the conversation, he is closing himself off to traditional epistemological and metaphysical projects, as well as to the perspectives of thinkers like Stirner and Nietzsche, despite his claim to be open to all of them. He can only consider them as topics of conversation as long as he remains committed to conversation, and thus never consider them as live options, or consider them as alternative life-projects to be pursued on their own terms. In insisting on the moral obligation of philosophers to continue the conversation of the West, he is insisting on the moral obligation of philosophers not to whole-heartedly adopt any of the alternatives which would tend to close off this conversation. Therefore, instead of decrying “the very notion of having a view, while avoiding having a view about having views,” Ibid., p. 371. Rorty has a rather clear view about having views: one should not hold any view whole-heartedly except the view that philosophy should be conversation, and this conversation should be the way to decide among views; that is, the way to decide among all views except the view that conversation should be the way to decide, which for Rorty is not open to discussion, but is a moral obligation. All perspectives are encouraged in the conversation, but the conversational morality has already prescribed that these views should not be whole-heartedly adopted by responsible individuals. Requiring that philosophy be conversation, Rorty closes off numerous possible life-styles, and almost all traditional philosophical projects: he merely saves the appearances of these alternatives. Morally required to continue the conversation, philosophy becomes just talk. Along the same lines, when Rorty claims that the normal and abnormal discourses “do not compete, but rather help each other out,” Ibid., p. 346. he assumes that the epistemological and metaphysical discourses will be helped by various abnormal discourses, and assumes thinkers like Nietzsche and Stirner will be helped by being made to see the significance of societies which have fallen together and are united by civility. Yet, in doing this, Rorty is not attempting to understand - either sympathetically or intellectually - what it would mean to help these projects on their own terms, and as such is not trying to understand and assimilate these alternatives as he claims he is. Rather, he is holding each of these alternatives up to his own ideal of an “open conversation,” and judging what it would mean to “help out” these alternatives only according to his own particular standards. In continually translating what others are offering into his own particular frame of reference, he does not appreciate these philosophical alternatives for their worth as individual activities which can contribute to life and/or society, but values them only for what they can contribute to his larger project, the conversation of humankind. However, if these alternatives were taken seriously, then they would surely be seen to compete with his view which advocates social criteria for adjudicating disputes, thereby denying many of the fundamental aspects of the above-mentioned alternative philosophical under-takings. It should be seen that contrary to what Rorty suggests, edification also “provides only some, among many, ways of describing ourselves,” Ibid., p. 361. and is only one type of human project among many others. In suggesting that we shift our focus “from the relation between human beings and the objects of their inquiry to the relation between alternative standards of justification, and from there to the actual changes in these standards which make up intellectual history,” Ibid., pp. 389–390. Rorty neither breaks free from traditional concerns, nor brings the focus of attention onto our own lives. As Bernstein notes, “there is a sense in which Rorty himself is obsessed. It is almost as if he can't quite ‘let go’ and accept the force of his own critique. It is as if Rorty himself has been more deeply touched by what he is attacking than he realizes.... He himself is obsessed with the obsessions of philosophers.” R.J. Bernstein, “Philosophy in the Conversation of Mankind,” pp. 767, 775.As a result of this, Richard Eldridge correctly notes that Rorty is unable to realize that “[c]riticism matters just insofar as it enables us fruitfully to develop our lives and our practices out of the past.” Richard Eldridge, “Philosophy and the Achievement of Community: Rorty, Cavell and Criticism,” Metaphilosophy 14, No. 2 (1983), p. 124. As an alternative to the Rortian attitude, I invite the reader to entertain a perspective which is not primarily concerned with identifying oneself in accordance with, or in opposition to, particular traditions, but rather with assimilating and utilizing all previous philosophical labors in order to achieve the greatest appreciation of one's own personal possibilities, and the fullest expression of one's own powers

This paper is a critique of a project, outlined by Laudan et al. (1986) recently in this journal, for empirically testing philosophical models of change in science by comparing them against the historical record of actual scientific practice. While the basic idea of testing such models of change in the arena of science is itself an appealing one, serious questions can be raised about the suitability of seeking confirmation or disconfirmation for large numbers of specific theses drawn from a massive list of claims abstracted from the writings of a few philosophers of science. The present paper discusses what one might reasonably expect from a model of change in science and then compares some clusters of theses from Laudan et al. with developments in recent theoretical physics. The results suggest that such straightforward testing of theses may be largely inconclusive.

Elementary results concerning the connections between deductive relations and probabilistic support are given. These are used to show that Popper-Miller's result is a special case of a more general result, and that their result is not very unexpected as claimed. According to Popper-Miller, a purely inductively supports b only if they are deductively independent — but this means that a b. Hence, it is argued that viewing induction as occurring only in the absence of deductive relations, as Popper-Miller sometimes do, is untenable. Finally, it is shown that Popper-Miller's claim that deductive relations determine probabilistic support is untrue. In general, probabilistic support can vary greatly with fixed deductive relations as determined by the relevant Lindenbaum algebra.

The ubiquity of chaos in classical mechanics (CM), as opposed to the situation in standard quantum mechanics (QM), might be taken as speaking against QM being the fundamental theory of physical phenomena. Bohmian mechanics (BM), as a formulation of quantum theory, may clarify both the existence of chaos in the quantum domain and the nature of the classical limit. Two interesting possibilities are (i) that CM and classical chaos are included in and underwritten by quantum mechanics (BM) or (ii) that BM and CM simply possess a common region of (noninclusive) overlap. In the latter case, neither CM nor QM alone would be sufficient, even in principle, to account for all of the physical phenomena we encounter. In this talk I shall summarize and discuss the implications of some recent work on chaos and on the classical limit within the framework of BM

Any division between scientific practice and a metalevel of the methods and goals of science is largely a false dichotomy. Since a priori, foundationist or logicist approaches to normative principles have proven unequal to the task of representing actual scientific practice, methodologies of science must be abstracted from episodes in the history of science. Of course, it is possible that such characteristics could prove universal and constant across various eras. But, case studies show that they are not in anything beyond the strictures applied to everyday, commonsense reasoning (e.g., a requirement of noncontradiction in a deductive argument). Hence, even if some presently-on-offer methodology or description of past scientific practice were adequate, it need not remain so for current (‘frontier’) areas of science. For this reason, it is important to examine recent episodes in, say, high-energy physics. Results from case studies of several episodes in that field are used to argue that successful practice leads scientists to countenance essential changes in the methodological framework at the levels of the criteria employed in judging theories (i.e., what counts for an explanation and what are canons of rationality) and of the goals of science. *Partial support for this research was provided by the History and Philosophy of Science Program of the National Science Foundation under grants Nos. SES-8606472 and SES-8705469. A preliminary version of this paper was given at an HPS seminar at King's College, London University in May 1988. Helpful comments and useful criticisms were made by several colleagues, especially Ernan McMullin, Heinz Post and Simon Saunders (none of whom are to be held responsible for or necessarily even in agreement with the views expressed here.).

On his death in 1997 Isaiah Berlin was widely hailed as a leading philosopher of political liberalism. This article takes the position that Berlin’s philosophical views, particularly those on freedom and cultural pluralism, can also be construed as a valuable guide for historians working in the present, “postmodernist” climate of debate. It further argues that Berlin’s character and career, the subjects already of considerable critical inquiry, lend added authority to these views. The focus is on three lengthy essays on history written by Berlin in the 1950s, one of which was first published in the first issue of this journal. The article concludes, following Berlin, that it is the responsibility of historians, as historians, to recognize the often incommensurate plurality of ultimate values to which their fellow human beings historically have subscribed and to judge, as judge they sometimes must, with that recognition fully in mind. If the result of these as well as the other choices that they make is a plurality of histories, of contending subjects, approaches, methods, and outcomes, that is only to be expected, indeed welcomed. It is freedom in practice, and infinitely preferable as such to any known alternative

In the preceding article, [3], Peter Machamer states three objections to my recent attempt to define ‘observation term’. While I believe that all Machamer's objections are mistaken, as I will try to show, his discussion does touch on two problems which have forced revisions. Both his first and second objections are that my definition is too restrictive because its second necessary condition for a term ‘O‘ being an observation term rules out too many terms which are obviously observation terms. The condition is :For any term, 'P' if 'There is an O ' entails the statement, 'There is a P-thing', then ‘Under certain conditions, some P-thing would appear as P to any standard observer’ is true.

Researchers have studied marketing ethics from several perspectives. Few studies, however, have analyzed supervisory reactions to unethical behavior by salespeople. The results of this study using a 2 × 3 factorial design showed that the performance level of the salesperson and the consequences of the salesperson''s actions influenced some types of discipline used by a sample of 246 sales managers. The findings both support and contradict prior research on how sales managers respond to unethical sales force behavior.

The nature of the connection between theory and observation has been a major source of difficulty for philosophers of science. It is most vexing for those who would reduce the terms of a theory to those of an observation language, e.g. Carnap, Braithwaite, and Nagel. Carnap's work, particularly his treatment of physical theories as partially interpreted formalisms, forms the point of focus of this paper. Carnap attempted to make the connection between theory and observation through correspondence postulates. It is pointed out that such postulates depend in critical ways upon theoretical truths. This particular type of theoretical dependence produces serious trouble for Carnap's approach. For reasons given it may make it untenable. Furthermore, this problem when generalized creates difficulty for any similar reductionist program. Not only is this kind of theoretical dependence pointed out, but more important, the logical conditions which produce it are revealed. In this way light is shed upon the formal characteristics of the notion of theory dependence, especially upon the way in which observation terms depend upon theories for their meaning
