Co-published with the University of Queensland Press. HPC holds rights in North America and U. S. Dependencies. Since its first publication in 1976, Alan Chalmers's highly regarded and widely read work--translated into eighteen languages--has become a classic introduction to the scientific method, known for its accessibility to beginners and its value as a resource for advanced students and scholars. In addition to overall improvements and updates inspired by Chalmers's experience as a teacher, comments from his readers, and recent developments (...) in the field, this fourth edition features an extensive chapter-long postscript that draws on his research into the history of atomism to illustrate important themes in the philosophy of science. Identifying the qualitative difference between knowledge of atoms as it figures in contemporary science and metaphysical speculations about atoms common in philosophy since the time of Democritus offers a revealing and instructive way to address the question at the heart of this groundbreaking work: What is this thing called science?

The authors develop an axiomatic theory of nonexistent objects and and give a formal semantics for the language of the theory.

Hans Reichenbach was a formidable figure in early-twentieth-century philosophy of science. Educated in Germany, he was influential in establishing the so-called Berlin Circle, a companion group to the Vienna Circle founded by his colleague Rudolph Carnap. The movement they founded—usually known as "logical positivism," although it is more precisely known as "scientific philosophy" or "logical empiricism"—was a form of epistemology that privileged scientific over metaphysical truths. Reichenbach, like other young philosophers of the exact sciences of his generation, was deeply impressed (...) by the far-reaching changes in physics brought about by Einstein's special and general theories of relativity. Reichenbach responded to scientific advances by doing fundamental work in space-time theories, in quantum mechanics, in statistical mechanics, and in the development of probability theory—making him the most important philosopher of physics in the first generation of logical empiricism. Forced from his academic position by the Nazi race laws in 1933, Reichenbach wrote _Experience and Prediction_ at the University of Istanbul, where had had fled, expressly to introduce logical positivism to English speakers. In the two decades following World War II, during the explosion of scientific advances in North America, logical positivism was the reigning theory of the philosophy of science and Reichenbach was at the peak of his career. But, inevitably, support for logical positivism began to wane as it became obvious that the justification of scientific theories could not be entirely resolved by relying on strictly formal, technical processes. The growth of the discipline of the history of philosophy of science, which has created an audience of scholars eager for seminal classics in scientific philosophy, and the evidence supporting a historicist paradigm within logical positivism are two important reasons to make _Experience and Prediction_ available once again. "Hans Reichenbach's_ Experience and Prediction_ is one of the most important books in twentieth-century philosophy of science. Its author was, along with Rudolf Carnap, one of the two principal ambassadors to North America of the exciting new European philosophical movement known here under the names 'Logical Positivism' and 'Scientific Philosophy.' In 1938, when the book was published, Reichenbach was an exile from his native Germany, teaching in Istanbul, Turkey, and about to emigrate to the United States to take up a prestigious position at UCLA. He wrote_ Experience and Prediction_ in English as his calling card to his new American colleagues. More than any other single book,_ Experience and Prediction_ set the agenda for the new discipline of the philosophy of science that was to emerge after World War II as, perhaps, the most exciting new area in North American philosophy. Many of the problems still at the focus of discussion were given their classic formulations in this book. Long out of print,_ Experience and Prediction_ appears here in a new edition accompanied by a splendid historical introduction by the noted young philosopher and historian of the philosophy of science, Alan Richardson. A jewel of a book may once again be appreciated in its proper setting." —Don A. Howard, University of Notre Dame. (shrink)

The phenomenon of rigid designation - in particular, de jure rigidity - is typically treated metaphysically. The picture is: reference is gained in a way that puts no constraints on what an object in other worlds, or counterfactual situations must be like, in order to be the referent of that term, other than 'being this thing'. This allows 'pure metaphysical' investigation into, and discovery of 'the nature' of the referent. It is argued that this presupposes a 'privileged' ontology, of a (...) sort that is far from obvious. An alternative picture of rigidity is sketched, terms have associated criteria of identity and criteria of application for counterfactual situations. A term is rigid when these coincide. Aside from being a better account of rigidity, it also undermines the picture of rigid terms allowing us to 'metaphysically' investigate the nature of the referent: matters of identity and essence for the referent are settled by these semantic constraints (though it can be done in a way that allows are a posteriori necessities).

The prospect for widespread therapeutic use of human fetal tissues has aroused strong emotions and prompted several objections. Fetal tissue transplantation circumscribed by medical and moral limits will not erode important ethical values, but the pace of scientific research must not preempt public debate and a verdict consistent with societal values.

In the last few years, off-line simulation has become an increasingly important alternative to standard explanations in cognitive science. The contemporary debate began with Gordon (1986) and Goldman's (1989) off-line simulation account of our capacity to predict behavior. On their view, in predicting people's behavior we take our own decision making system `off line' and supply it with the `pretend' beliefs and desires of the person whose behavior we are trying to predict; we then let the decision maker reach a (...) decision on the basis of these pretend inputs. Figure 1 offers a `boxological' version of the off-line simulation theory of behavior prediction.(1). (shrink)

‘Fascinating’, ‘brilliant’, ‘oddly moving’, ‘a warm human picture’ – this biography was enthusiastically received when it came out in 1957. And no wonder. It is not only the lively story of a distinguished man but a lucid account of his work and its significance. The author, who was himself a philosopher and journalist, has followed the bright thread of Russell’s personality with affectionate insight, from the three-day-old baby who looked about him ‘in a very energetic way’, and the boy who (...) jibbed at taking Euclid on trust, through the many turns of his life, to the undimmed octogenarian, still questioning and still deeply concerned. The subject is a great one and the biographer has matched it. (shrink)

Represents the most comprehensive and current survey of the various challenges to the Modern Synthesis theory of evolution. Incorporates a variety of theoretical and disciplinary perspectives, from evolutionary biologists, historians and philosophers of science. These essays constitute the state of the art in the current debate on the status of the Modern Synthesis.

Should a philosophical account of perceptual knowledge accord a justificatory role to sensory experiences? This discussion raises problems for an affirmative answer and sets out an alternative account on which justified belief is conceived as well-founded belief and well-foundedness is taken to depend on knowledge. A key part of the discussion draws on a conception of perceptual-recognitional abilities to account for how perception gives rise both to perceptual knowledge and to well-founded belief.

This study explores the way that belief systems, interactions with social or experimental environments, and skills at the “control” level in decision‐making shape people's behavior as they solve problems. It is argued that problem‐solvers' beliefs (not necessarily consciously held) about what is useful in mathematics may determine the set of “cognitive resources” at their disposal as they do mathematics. Such beliefs may, for example, render inaccessible to them large bodies of information that are stored in long‐term memory and that are (...) easily retrieved in other circumstances. In other cases, individuals' reactions to an experimental setting (fear of failure, or the desire to “look mathematical” while being videotaped) may induce behavior that is almost pathological—and at the same time, so consistent that it can be modeled. In general, such “environmental” factors establish the context within which individuals access and utilize the information potentially at their disposal.Protocols illustrating these points are presented and discussed. A model based on an axiomatization of students' beliefs about plane geometry is outlined, and is shown to correspond closely to their problem‐solving performance. A framework is offered for analyzing problem‐solving performance at three qualitatively different levels: access to cognitive resources stored in LTM, executive or control decision‐making, and belief systems.

Cultural pluralism is both a fact and a norm. It is a fact that our world, and indeed our society, are marked by a large diversity of cultures delineated in terms of race, class, gender, ethnicity, religion, ideology, and other partly interpenetrating variables. This fact raises the normative question of whether, or to what extent, such diversities should be recognized or even encouraged in policies concerning government, law, education, employment, the family, immigration, and other important areas of social concern.

Liberal egalitarians agree that the state should protect and promote the freedom of the individual and strive to establish equality of opportunity and resources. They tend to disagree, however, about what these principles entail concerning the state's attitude to the success or failure of the different national cultures which co-exist in many modern political communities. To some it seems obvious that, given the profound importance of culture in shaping a person's identity and outlook, treating people in accordance with liberal egalitarian (...) principles means ensuring the equal survival and success of the cultures to which they belong. Actual practice seems to accord with this conviction to at least some degree in many places in the world: in countries like Canada, Belgium, Spain, and the United Kingdom, to mention just a few, minority cultures are provided with at least some of the political and financial resources needed to ensure their own survival and flourishing.

Examines the nature of rhetorical theory and criticism, the rhetoric of science, and the impact of poststructuralism and postmodernism on contemporary accounts of rhetoric.

This paper presents a unified account of the meaning of the spatial relational terms right, left, in front of, behind, above and below. It claims that each term has three types of meanings, basic, deictic and intrinsic, and that the definitions of each type of meaning are identical in form for all six terms. Restrictions on the use of the terms, which are different for above and below than for the rest, are explained by a general constraint on all uses (...) of spatial relational terms, the framework vertical constraint. This constraint depends on the existence of a fourth type of meaning for above and below, one defined by the framework in which the related objects are located. It is argued that a theory centred on the framework vertical constraint is preferable to one centred on the principle of canonical orientation (Levelt, 1984). (shrink)

ABSTRACT All of the major German Idealists perceived a gap between ideals and social reality. Kant sought to bridge this gap through an institutional design that forced self-interest to track the public good. Fichte embraced cultural nationalism, according to which, to overcome the gap between ideals and reality, a nation must revive and strengthen its original culture. Hegel’s solution, in contrast, rests on the idea of ethical habituation. For Hegel, the institutions of a well-designed social order encourage the habits and (...) virtues needed for the successful reproduction of that order. The article reflects on the implications of these contrasts for the prospects of liberal democracy. (shrink)

Policy makers are understandably interested—for both political and moral reasons—in following Thaler and Sunstein's recommendation to use ‘choice architecture’ , or other ‘nudges’, to promote desirable behaviour in ways that are allegedly compatible with personal freedom.1 Yashar Saghai's intricate analysis shows that simply maintaining the target's choice-set is insufficient to preserve the target's freedom when the nudge bypasses the target's deliberative capacities—as it is specifically designed to do.2 In his friendly amendment to Thaler and Sunstein's project, Saghai advances a more (...) robust account of nudges in which fewer policies would count as nudges, but those that do count as nudges would be less troublesome. In this commentary, I briefly discuss several issues raised by Saghai's project, some of which go beyond the topic of nudges. How important is definitional salvaging? If a ‘substantially controlling’ influence were more efficacious in promoting healthy behaviours, we would have a trade-off between the efficacy of a policy and its compatibility with freedom. Saghai states that an influence can be morally permissible even if it is ‘substantially controlling’ and, therefore, does not qualify as a nudge. So even on Saghai's definitional project it is not clear how much work it does in distinguishing the morally permissible from the morally impermissible. The …. (shrink)

''The problem of Transcendence is the problem of our time. " I Needless to say, Transcendence was a particularly lively i~sue when Karl Heim wrote these words in the mid-1930's. Within the province of philosophi cal theology and philosophy of religion, however, it is always the prob lem, as Gordon Kaufman has recently reminded us. 2Por the question concerning the nature and the reality of Transcendence has not only to do with self-transcendence, but with the being of Transcendence-Itself, that is (...) to say, with the nature and the reality of God as experienced and understood at any given time or place. Now there are those today who would claim that any further discus sion of the latter half of this proposition, namely,Transcendence-Itse1f or God, is worthless and quite beside the point. Such persons would claim that the particular logia represented by the theological sciences has collapsed by virtue of its object having disappeared. Indeed, when one surveys the contemporary scene in philosophy and theology, there is a good deal of evidence that this is the case':"" theology of late having be come something of a "spectacle," to use Pritz Buri's term. One of the reasons for this, we here contend, is that the richness and the diversity of the meaning of Transcendence has been lost. And even though we do not here intend to resolve the issue, neither do we assume that such an enqui ry is either impossible or irrelevant. (shrink)

Two criticisms of my argument in "reason and morality" were presented by christopher mcmahon (in "gewirth's justification of morality," "philosophical studies", September 1986). I reply to each criticism, Showing that mcmahon has misconstrued my use of 'ought' as action-Guiding and my universalization of the agent's rights-Judgment, As well as my concept of prudential rights. A general defect is that he has not understood how central to my argument is the agent's conative and rational standpoint.

For centuries tradition had it that knowledge is justified true belief. Then Edmund Gettier produced cases that refute that traditional view – or so most philosophers think. I disagree. The widespread intuition lying behind the so-called ‘Gettier Cases’ is that there is epistemic bad luck (we can unluckily fail to know), but no epistemic good luck (we cannot luckily know). I reject this puritanical intuition. I also question the externalist or reliabilist views of knowledge and/or justification that the Gettier Cases (...) have spawned. (shrink)

It is instructive to view the scientific revolution from the point of view of Robert Boyle’s distinction between intermediate and ultimate causes. From this point of view, the scientific revolution involved the identification of intermediate causes and their investigation by way of experiment as opposed to the specification of ultimate causes of the kind involved in the corpuscular matter theories of the mechanical philosophers. The merits of this point of view are explored in this paper by focussing on the hydrostatics (...) of Pascal and Boyle, understood as the experimental investigation of the action of the intermediate causes weight and pressure. The distinctive features of this new science are highlighted by comparing it with two alternative versions of hydrostatics, that of Stevin and that of Descartes. (shrink)

Controversy has surrounded the interpretation of the so-called 'Diodorean' and 'Chrysippean' conditionals of the Stoics. I critically evaluate and reject two interpretations of each of them: as expressing natural laws, and as strict conditionals. In doing so I engage with the work of authors such as Frede, Gould, Hurst, the Kneales, Mates, and Prior. I conclude by offering my own proposal for where these Stoic conditionals should be located on a 'ladder' of logical strength.

This is a paper about ‘human rights pluralism’, and about how human rights’ inherent flexibility can be embraced by development policy-makers and practitioners in ways that can aid the goals of both development and human rights. The paper argues that, even though human rights are often expressed in legal terms – terms that are usually associated with the rigidity of obligation – human rights are inherently pluralistic. This is for two reasons. First, upon closer inspection, human rights laws, and especially (...) international human rights laws, far from imposing rigidity, reflect substantial elasticity as regards their statement, interpretation and implementation. And second, in any case, it is and always has been a mistake not to consider human rights laws within the unavoidably influential philosophical, cultural and economic contexts in which they operate. The political, in other words, is both a necessary and desirable dimension of the legal expression of human rights. Drawing upon this conceptual basis, the paper identifies six specific ‘grammatical features’ of human rights and describes how and why they might be profitably employed by development specialists.

The concept of evolvability—the capacity of a population to produce and maintain evolutionarily relevant variation—has become increasingly prominent in evolutionary biology. Paleontology has a long history of investigating questions of evolvability, but paleontological thinking has tended to neglect recent discussions, because many tools used in the current evolvability literature are challenging to apply to the fossil record. The fundamental difficulty is how to disentangle whether the causes of evolutionary patterns arise from variational properties of traits or lineages rather than being (...) due to selection and ecological success. Despite these obstacles, the fossil record offers unique and growing sources of data that capture evolutionary patterns of sustained duration and significance otherwise inaccessible to evolutionary biologists. Additionally, there exist a variety of strategic possibilities for combining prominent neontological approaches to evolvability with those from paleontology. We illustrate three of these possibilities with quantitative genetics, evolutionary developmental biology, and phylogenetic models of macroevolution. In conclusion, we provide a methodological schema that focuses on the conceptualization, measurement, and testing of hypotheses to motivate and provide guidance for future empirical and theoretical studies of evolvability in the fossil record.

In his Introduction to Logical Theory, Strawson argues that Aristotelian logic can be given a successful interpretation into ordinary English, but not into the symbolism of Principia Mathematica, on the grounds that Aristotelian logic and ordinary English share something absent in PM, namely, the doctrine of presupposition. It is argued that Strawson is mistaken. PM does justice to the logical rules of Aristotelian logic and also has a fully articulated doctrine of presupposition.

I believe that Moore's appeal to common sense has been misunder-stood both by his defenders and his critics. Besides the mistakes of the latter, there is one enormous howler which, in my opinion, the former have committed. This is to confuse or coalesce two quite distinct appeals which he made, namely the appeal to common sense and the appeal to ordinary language.
