Darwin himself suggested the idea of generalizing the core Darwinian principles to cover the evolution of social entities. Also in the nineteenth century, influential social scientists proposed their extension to political society and economic institutions. Nevertheless, misunderstanding and misrepresentation have hindered the realization of the powerful potential in this longstanding idea. Some critics confuse generalization with analogy. Others mistakenly presume that generalizing Darwinism necessarily involves biological reductionism. This essay outlines the types of phenomena to which a generalized Darwinism applies, and (...) upholds that there is no reason to exclude social or economic entities. (shrink)

It has been suggested that God can act on the world by operating within the limits set by Heisenberg's uncertainty principle (HUP) without violating the laws of nature. This requires nature to be intrinsically indeterministic. However, according to the statistical interpretation the quantum mechanical wavefunction represents the average behavior of an ensemble of similar systems and not that of a single system. The HUP thus refers to a relation between the spreads of possible values of position and momentum and so (...) is consistent with a fully deterministic world. This statistical interpretation of quantum mechanics is supported by reference to actual measurements, resolves the quantum paradoxes, and stimulates further research. If this interpretation is accepted, quantum mechanics is irrelevant to the question of God's action in the world. (shrink)

Einstein’s special theory of relativity has had a wide influence on fields far removed from physics. It has given the impression that physics has shown that there are now no absolute truths, that all beliefs are relative to the observer, and that traditional stable landmarks have been washed away. We each have our own frame of reference that is as good as any other frame, so that there are no absolute standards by which our actions may be judged. The predictions (...) of relativity theory, such as the elimination of simultaneity, the variation of mass with velocity, and the equivalence of mass and energy, are all highly counterintuitive and yet are precisely confirmed by detailed measurements. The clear rocklike mechanical physics of Newton seems to have dissolved into a swirling mist of unintelligible concepts, and familiar certainties seem to have disappeared. A detailed analysis of relativity theory shows, however, a completely different picture. Properly understood, it is a logical extension of Newtonian physics that expresses the relations of space and time in a more exact and elegant way and in the process shows forth more clearly the invariant features of the world. The apparently counterintuitive features appear as natural consequences that extend and refine our classical concepts. The traditional landmarks remain, but God’s world is more subtle than we had previously imagined. (shrink)

Max Bennett is a distinguished Australian neuroscientist, Peter Hacker an Oxford philosopher and leading authority on Wittgenstein. A book resulting from their collaboration, Philosophical Foundations of Neuroscience, has received high praise. According to the Blackwell website, G.H. von Wright asserts that it 'will certainly, for a long time to come, be the most important contribution to the mind-body problem that there is'; and Sir Anthony Kenny says it 'shows that the claims made on behalf of cognitive science are ill-founded'.

I adopt a cladistic view of species, and explore the possibility that there exists an equally valuable cladistic view of organismic traits. This suggestion seems to run counter to the stress on functional views of biological traits in recent work in philosophy and psychology. I show how the tension between these two views can be defused with a multilevel view of biological explanation. Despite the attractions of this compromise, I conclude that we must reject it, and adopt an essentially cladistic (...) conception of biological traits. (shrink)

Digeser contends that our rich and varied practices of friendship multiply and moderate connections to politics. Along the way, she sets forth a series of ideals that appreciates friendship's many forms and its dynamic relationship to individuality, citizenship, political and legal institutions, and international relations.

Empty names are a problem for Russellians. I describe three ways to approach solving the problem. These are positing gappy propositions as contents, nonsingular propositions as contents, or denying that sentences containing empty names have contents. I discuss methods for deciding between solutions. I then argue for some methods over others and defend one solution using those methods. I reject the arguments that either intuitions about truth value, truth, content, or meaningfulness can decide between the solutions. I give an alternative (...) argument which does decide between the three solutions. The alternative is based on the idea that a sentence and its internal negation are contrary: they cannot both be true, but they might both be false. I argue from Russellian premises to the conclusion that such sentences cannot be assigned truth values when they contain empty names. The argument shows that no Russellian should assign a truth value to a sentence containing an empty name, and therefore that no Russellian should assign a proposition as the content of such a sentence. This shows that Russellians should conclude that sentences containing empty names do not have contents, i.e. the no proposition view. (shrink)

The widely cited Nuffield Council on Bioethics ‘Intervention Ladder’ structurally embodies the assumption that personal autonomy is maximized by non-intervention. Consequently, the Intervention Ladder encourages an extreme ‘negative liberty’ view of autonomy. Yet there are several alternative accounts of autonomy that are both arguably superior as accounts of autonomy and better suited to the issues facing public health ethics. We propose to replace the one-sided ladder, which has any intervention coming at a cost to autonomy, with a two-sided ‘Balanced Intervention (...) Ladder,’ where intervention can either enhance or diminish autonomy. We show that not only the alternative, richer accounts of autonomy but even Mill’s classic version of negative liberty puts some interventions on the positive side of the ladder. (shrink)

This paper is as much about a particular depiction of the tribune P. Sulpicius Rufus as it is about Cicero's De Oratore, a dialogue regularly called upon by historians to give evidence on the 90s b.c. and the characters who take part in the conversation it depicts. My main focus is literary: I will argue that, given what we know about the historical Sulpicius, Cicero's choice of Sulpicius for a prominent minor role in De Oratore drives the tragic historical framework (...) that undercuts the optimism expressed within the dialogue by the main protagonist L. Licinius Crassus for the civic value of oratory. The Rhetorica ad Herennium illustrates a certain type of allegory with the statement ‘as if one should call Drusus a “faded reflection of the Gracchi”’. In De Oratore, Drusus’ friend and successor Sulpicius functions as a reflection of the Gracchi and his eloquence reinforces the problem posed by such orators as the notoriously eloquent Gaius Gracchus for any such grand claims about the civic value of oratory. By examining Cicero's use of relatively recent history, we therefore discover that De Oratore is significantly more pessimistic than it may at first seem. This pessimism, however, has important implications for historians, since expanding our understanding of De Oratore as a literary construct should encourage historians to be significantly more cautious about using the text as a historical source. As Görler points out with regard to Crassus’ swansong at De or. 3.4–5, although ‘a naive reader of Oratorum Romanorum Fragmenta could be left with the impression that some sentences are quite well attested’, most of the fragments of Crassus’ speech can actually be traced back to De Oratore. Likewise, a significant proportion of the standard elements in Sulpicius’ backstory go back to De Oratore and become a great deal less convincing once we accept De Oratore as a sustained fictional account featuring people who were neither as politically ‘safe’ nor as intellectually united as Cicero would have them be. My secondary focus in this paper is therefore on the broader lessons to be drawn from Sulpicius’ role in De Oratore. I will begin by outlining the historical context of the dialogue, which was written in the mid 50s but is set in 91, a few weeks before the natural death of Crassus, one of its two protagonists. Next, I will discuss the dialogue's literary context, specifically the Platonic allusions Cicero embeds within the text. These allusions encourage us to treat De Oratore’s historical framework carefully, if not sceptically, and I will outline the ‘off notes’ struck by references to the Gracchi and by the presentation of Crassus and Antonius before examining the problem Sulpicius poses for a straightforwardly optimistic reading of De Oratore. I will conclude by considering first the literary implications for De Oratore of accepting that Sulpicius is a deliberately problematic character and then the historical implications of taking a sceptical approach towards De Oratore as an historical source for our picture of Sulpicius.

Responses to my article on Dawkins and God have fallen into two classes: those that challenge my criticism of Dawkins’ atheism, and those that challenge my criticism of the morality on display in some Bible stories. I will briefly respond to those in the first class, and then those in the second class. P. J. Moss suggests I am attracted to “the Cartesian notion of mind body dualism,” and do not have regard to “the work of those philosophers of mind (...) who … see the task of the philosopher as posing the problem into a precise enough form so that it admits of scientific resolution;” and he commends the work of John Searle. I am indeed attracted to a kind of dualism. However, it is not the Cartesian dualism of “two distinct realms” rejected by Searle, but rather a dualism that accepts, as Searle does, that there are two categories of empirical reality, subjective and objective, which are mutually irreducible The Rediscovery of the Mind, pp19, 98), and that there are features of subjective reality that cannot be fully understood in terms of objective reality. In a major work published in 2001, Rationality in Action, Searle even leaves open as a reasonable possibility a view I support, namely that consciousness may be able to cause things that cannot be fully explained by the causal behaviour of neurons, and he also supports a non Humean notion of the self, as an entity that can, as a whole, consciously try to do things: see my review in Journal of Consciousness Studies 9, 92 94. In any event, my argument against Dawkins does not depend on acceptance of dualism, just on the undoubted fact that science does not yet have the first idea what objective features are necessary and sufficient to give rise to subjectivity. Robert McLaughlin makes out a reasoned case against my three suggested errors in Dawkins. It would take a book to deal fully with points of the kind he raises, but I have to be brief here. (shrink)

Errol E. Harris’s review of Volume 3 of our new translation of Hegel’s Lectures on the Philosophy of Religion appeared in the Fall 1988 issue of The Owl of Minerva. I appreciate his several favorable comments, even though his review nowhere evaluates the interpretative insights into Hegel’s treatment of “The Consummate Religion” that may have been gained by separating the four series of lectures between 1821 and 1831 and reconstructing them as exactly as possible; thus Harris avoids an assessment of (...) the fundamental contribution that the new edition has sought to make to Hegel studies. It is inappropriate for me to quarrel here with the interpretations of reviewers. But I am compelled to address several serious allegations contained in this review. (shrink)

Assuming it rational to treat other persons' probabilities as epistemically significant, how shall their judgements be weighted (Barnes [1998])? Several plausible methods exist, but theorems in classical psychometrics greatly reduce the importance of the problem. If scientists' judgements tend to be positively correlated, the difference between two randomly weighted composites shrinks as the number of judges rises. Since, for reasons such as representative coverage, minimizing bias, and avoiding elitism, we would rarely employ small numbers of judges (e.g. less than 10), (...) the difference between two weighting systems becomes negligible. Suggestions are made for quantifying verisimilitude, identifying 'types' of scientists or theories (taxometrics), inferring latent factors, and estimating reliability of pooled judgements. (shrink)

Philosophers have had an interest in language from the earliest times but the twentieth century, with its so-called 'linguistic turn' in philosophy, has seen a huge expansion of work focused specifically on language and its foundations. No branch of philosophy has been unaffected by this shift of emphasis. It is timely at the end of the century to review and assess the vast range of issues that have been developed and debated in this central area. The distinguished international contributors present (...) a clear, accessible guide to the fundamental questions raised by the philosophers about language. Contributions include Graeme Forbes on necessity, Susan Haack on deviant logics, Paul Horwich on truth, Charles Travis on Wittgenstein, L.J. Cohen on linguistic philosophy, Ruth Kempson on semantics and syntax and Christopher Hookway on ontology, to name but a few. A wide range of topics are covered from the metaphysics and ontology of language, language and mind, truth and meaning, to theories or reference, speech act theory, philosophy of logic and formal semantics. There are also articles on key figures from the twentieth century and earlier. Based on the foundation provided by the award-winning Encyclopedia of Language and Linguistics this single volume provides a collection of articles that will be an invaluable reference tool for all those interested in the area of philosophy of language, and also to those in cognitive science and psychology. All the articles have been thoroughly revised and updated. This volume gives a unique survey of topics that are at the very core of contemporary philosophy. (shrink)
