It is a popular view thatpractical deliberation excludes foreknowledge of one's choice. Wolfgang Spohn and Isaac Levi have argued that not even a purely probabilistic self-predictionis available to thedeliberator, if one takes subjective probabilities to be conceptually linked to betting rates. It makes no sense to have a betting rate for an option, for one's willingness to bet on the option depends on the net gain from the bet, in combination with the option's antecedent utility, rather than on the offered (...) odds. And even apart from this consideration, assigning probabilities to the options among which one is choosing is futile since such probabilities could be of no possible use in choice. The paper subjects these arguments to critical examination and suggests that, appearances notwithstanding, practical deliberation need not crowd outself-prediction. (shrink)

Are theories ‘underdetermined by the evidence’ in any way that should worry the scientific realist? I argue that no convincing reason has been given for thinking so. A crucial distinction is drawn between data equivalence and empirical equivalence. Duhem showed that it is always possible to produce a data equivalent rival to any accepted scientific theory. But there is no reason to regard such a rival as equally well empirically supported and hence no threat to realism. Two theories are (...) empirically equivalent if they share all consequences expressed in purely observational vocabulary. This is a much stronger requirement than has hitherto been recognised— two such ‘rival’ theories must in fact agree on many claims that are clearly theoretical in nature. Given this, it is unclear how much of an impact on realism a demonstration that there is always an empirically equivalent ‘rival’ to any accepted theory would have—even if such a demonstration could be produced. Certainly in the case of the version of realism that I defend—structural realism—such a demonstration would have precisely no impact: two empirically equivalent theories are, according to structural realism, cognitively indistinguishable.

This paper offers an overview of "the species problem", arguing for a view of species as homeostatic property cluster kinds, positioning the resulting form of realism about species as an alternative to the claim that species are individuals and pluralistic views of species. It draws on taxonomic practice in the neurosciences, especially of neural crest cells and retinal ganglion cells, to motivate both the rejection of the species-as-individuals thesis and species pluralism.

Moral Realism is a systematic defence of the idea that there are objective moral standards. Russ Shafer-Landau argues that there are moral principles that are true independently of what anyone, anywhere, happens to think of them. His central thesis, as well as the many novel supporting arguments used to defend it, will spark much controversy among those concerned with the foundations of ethics.

One of the key achievements of critical realism has been to expose the modernist myth of universal reason, which holds that authentic knowledge claims must be objectively ‘pure’, uncontaminated by the subjectivity of local place, specific time and particular culture. Wright aims to address the lack of any substantial and sustained engagement between critical realism and theological critical realism with particular regard to: (a) the distinctive ontological claims of Christianity; (b) their epistemic warrant and intellectual legitimacy; and (...) (c) scrutiny of the primary source of the ontological claims of Christianity, namely the historical figure of Jesus of Nazareth. As such, it functions as a prolegomena to a much needed wider debate, guided by the under-labouring services of critical realism, between Christianity and various other religious and secular worldviews. This important new text will help stimulate a debate that has yet to get out of first gear. This book will appeal to academics, graduate and post-graduate students especially, but also Christian clergy, ministers and informed laity, and members of the general public concerned with the nature of religion and its place in contemporary society.

Call "radical moral theorizing" the project of developing a moral theory that not only tries to conform to our existing moral intuitions, but also manifests various theoretical virtues: consistency, simplicity, explanatory depth, and so on. Many moral philosophers assume that radical moral theorizing does not require any particular metaethical commitments. In this paper, I argue against this assumption. The most natural justification for radical moral theorizing presupposes moral realism, broadly construed; in contrast, there may be no justification for radical (...) moral theorizing if moral anti-realism is true.

_Grounds of Pragmatic Realism_ shows Hegel is a major epistemologist, who disentangled Kant’s critique of judgment, across the Critical corpus, from transcendental idealism, and augmented its enormous evaluative and justificatory significance for commonsense knowledge, the natural sciences and freedom of action.

Critical Realism and Marxism addresses controversial debates, revealing a potentially fruitful relationship; deepening our understanding of the social world and contibuting towards eliminating barbarism in contemporary capitalism.

Plausibly, mathematical claims are true, but the fundamental furniture of the world does not include mathematical objects. This can be made sense of by providing mathematical claims with paraphrases, which make clear how the truth of such claims does not require the fundamental existence of mathematical objects. This paper explores the consequences of this type of position for explanatory structure. There is an apparently straightforward relationship between this sort of structure, and the logical sort: i.e. logically complex claims are explained (...) by logically simpler ones. For example, disjunctions are explained by their (true) disjuncts, while generalizations are explained by their (true) instances. This would seem as plausible in the case of mathematics as elsewhere. Also, it would seem to be something that the anti-realist approaches at issue would want to preserve. It will be argued, however, that these approaches cannot do this: they lead not merely to violations of the familiar principles relating logical and explanatory structure, but even to reversals of these. That is, there are cases where generalizations explain their instances, or disjunctions their disjuncts. (shrink)

Scientific Realism is the optimistic view that modern science is on the right track: that the world really is the way our best scientific theories describe it to be. In his book, Stathis Psillos gives us a detailed and comprehensive study, which restores the intuitive plausibility of scientific realism. We see that throughout the twentieth century, scientific realism has been challenged by philosophical positions from all angles: from reductive empiricism, to instrumentalism and modern skeptical empiricism. Scientific (...) class='Hi'>Realism explains that the history of science does not undermine the notion of scientific realism, and instead makes it reasonable to accept scientific as the best philosophical account of science, its empirical success, its progress and its practice. Anyone wishing to gain a deeper understanding of the state of modern science and why scientific realism is plausible, should read this book. (shrink)

The paper discusses three talks, which were given at the meetings of the Philosophical Society of Berlin (Philosophische Gesellschaft zu Berlin) in the mid-1870s. In these talks, the principles of some main movements in contemporary philosophy (realism, absolute idealism, critical idealism) were elaborated and contrasted to each other. The paper focuses on the concepts of real-idealism and ideal-realism. All the discussants, Friedrich Frederichs, C. L. Michelet and J. H. von Kirchmann, introduce these concepts. Frederichs, an adherent of critical (...) idealism, argues only for the standpoint of real-idealism. Michelet, G. W. F. Hegel’s personal student and an adherent of absolute idealism, takes real-idealism and ideal-realism to be the two sides of the one coin. Kirchmann, an advocate of realism, regards real-idealism as an objective, and he is skeptical about the possibility to achieve it. (shrink)

We present a novel methodology for calculating the improvements obtained in successive versions of biomedical ontologies. The theory takes into account changes both in reality itself and in our understanding of this reality. The successful application of the theory rests on the willingness of ontology authors to document changes they make by following a number of simple rules. The theory provides a pathway by which ontology authoring can become a science rather than an art, following principles analogous to those that (...) have fostered the growth of modern evidence-based medicine. Although in this paper we focus on ontologies, the methodology can be generalized to other sorts of terminology-based artifacts, including Electronic Patient Records. (shrink)

Gerald Harrison identifies two Euthyphro-related concerns for divine command theories and makes the case that to the extent that these concerns make trouble for divine command theories they also make trouble for non-naturalistic moral realism and naturalistic moral realism. He also offers responses to the two concerns on behalf of divine command theorists. I show here that the parity thesis does not hold for the most commonly discussed version of divine command theory. I further argue that his responses (...) to the two concerns fail. Finally, I draw on some of Harrison’s ideas to identify an advantage that non-naturalistic moral realism has over divine command theories and naturalistic moral realism. (shrink)

This book is a systematic and constructive treatment of a number of traditional issues at the foundation of ethics, the possibility and nature of moral knowledge, the relationship between the moral point of view and a scientific or naturalistic world view, the nature of moral value and obligation, and the role of morality in a person's rational life plan. In striking contrast to many traditional authors and to other recent writers in the field, David Brink offers an integrated defense of (...) the objectivity of ethics. (shrink)

This paper provides a critical overview of the realist current in contemporary political philosophy. We define political realism on the basis of its attempt to give varying degrees of autonomy to politics as a sphere of human activity, in large part through its exploration of the sources of normativity appropriate for the political and so distinguish sharply between political realism and non-ideal theory. We then identify and discuss four key arguments advanced by political realists: from ideology, from the (...) relationship of ethics to politics, from the priority of legitimacy over justice and from the nature of political judgement. Next, we ask to what extent realism is a methodological approach as opposed to a substantive political position and so discuss the relationship between realism and a few such positions. We close by pointing out the links between contemporary realism and the realist strand that runs through much of the history of Western political thought. (shrink)
