A selection of essays dedicated to Hans Herzberger with affection and gratitude for both his profound work and his lasting example. Contributors: I. Levi (on whether and how a rational agent should be seen as a maximizer of some cognitive value), C. Normore (on medieval accounts of logical validity), J. P. Tappenden (on the local influences on Frege's doctrines), A. Urquhart (on the inexpressible), A. C. Varzi (on dimensionality and the sense of possibility), and S.

Offering an original perspective on the central project of Descartes' Meditations, this book argues that Descartes' free will theodicy is crucial to his refutation of skepticism. A common thread runs through Descartes' radical First Meditation doubts, his Fourth Meditation discussion of error, and his pious reconciliation of providence and freedom: each involves a clash of perspectives-thinking of God seems to force conclusions diametrically opposed to those we reach when thinking only of ourselves. Descartes fears that a skeptic could exploit this (...) clash of perspectives to argue that Reason is not trustworthy because self-contradictory. To refute the skeptic and vindicate the consistency of Reason, it is not enough for Descartes to demonstrate that our Creator is perfect; he must also show that our errors cannot prove God's imperfection. To do this, Descartes invokes the idea that we err freely. However, prospects initially seem dim for this free will theodicy, because Descartes appears to lack any consistent or coherent understanding of human freedom. In an extremely in-depth analysis spanning four chapters, Ragland argues that despite initial appearances, Descartes consistently offered a coherent understanding of human freedom: for Descartes, freedom is most fundamentally the ability to do the right thing. Since we often do wrong, actual humans must therefore be able to do otherwise-our actions cannot be causally determined by God or our psychology. But freedom is in principle compatible with determinism: while leaving us free, God could have determined us to always do the good. Though this conception of freedom is both consistent and suitable to Descartes' purposes, when he attempts to reconcile it with divine providence, Descartes's strategy fails, running afoul of his infamous doctrine that God created the eternal truths.

The notion that our society, its education system and its intellectual life, is characterised by a split between two cultures – the arts or humanities on one hand and the sciences on the other – has a long history. But it was C. P. Snow's Rede lecture of 1959 that brought it to prominence and began a public debate that is still raging in the media today. This fiftieth anniversary printing of The Two Cultures and its successor piece, A Second (...) Look features an introduction by Stefan Collini, charting the history and context of the debate, its implications and its afterlife. The importance of science and technology in policy run largely by non-scientists, the future for education and research, and the problem of fragmentation threatening hopes for a common culture are just some of the subjects discussed.

Between 1069, the year of his arrival at St. Martin in Mainz, where he spent the rest of his life in voluntary enclosure in a cell, and his death in 1082, the Irish monk Marianus Scottus dedicated countless hours to assembling the most sophisticated and comprehensive work on historical chronology that had ever been produced by a Latin writer up to that time. The fruits of his labors became a massive world chronicle, completed in 1076, whose most famous innovation consisted (...) in a far-reaching correction to the Christian, or “common,” era, which had been introduced by Dionysius Exiguus in the sixth century. Having compared the data of the Easter computus with the chronological parameters traditionally associated with the passion of Christ—the fifteenth day of the moon on Friday, 25 March—Marianus found that the only year in which the numbers could be made to fit was AD 12 rather than the traditionally accepted AD 34. As a result, he decided to predate the life of Jesus by twenty-two years, assigning his birth to the year corresponding to 22 BC. This gave rise to a new “corrected” era , which he used alongside its Dionysiac equivalent. (shrink)

There have been many claims that quantum mechanics plays a key role in the origin and/or operation of biological organisms, beyond merely providing the basis for the shapes and sizes of biological molecules and their chemical affinities. These range from Schr¨odinger’s suggestion that quantum fluctuations produce mutations, to Hameroff and Penrose’s conjecture that quantum coherence in microtubules is linked to consciousness. I review some of these claims in this paper, and discuss the serious problem of decoherence. I advance some further (...) conjectures about quantum information processing in bio-systems. Some possible experiments are suggested. © 2004 Elsevier Ireland Ltd. All rights reserved. (shrink)

Becoming autonomous is a process of coming to realise oneself in shared, socio-historical practices. There can be no self before these practices, but their existence is no guarantee for selfhood either: one can be heteronomous through one's successful participation in various practices if that participation is not a genuine expression of one's own personhood. This means that the sheer capability to participate in the practices in which one finds oneself is not sufficient for personal autonomy. Something else is required before (...) the self is realised in shared, socio-historical practices. How can this be, if as we said, there can be no self before these practices? By what principle do we decide whether a particular expression of selfhood in a socio-historical practice is genuine? If there can only be a self within socio-historical practices, it stands to reason that we can find it only there. If, however, one's participation cannot be considered in advance as a genuine expression of oneself, what we may expect to find is perhaps only a fragment, a hint of autonomy always already entangled in heteronomous elements, or things that would be different if one could have so chosen. To come to an understanding of oneself, then, will require more than just a handle on one's existence in various practices. It will require the capacity to see one's participation in this socio-historically determined practice as a fragment of a whole, a particular instance of something more general which points beyond our present participation in these particular, socio-historically determined practices towards a horizon of possibility that recedes beyond our grasp whenever we try to make definitive sense out of a possibility for agency.

The present volume is, we believe, the first-ever edited volume devoted to the emotion of disgust. In this chapter we address the following issues: 1. Why was disgust almost completely ignored until about 1990, 2. Why has there been a great increase in attention to disgust since about 1990?, 3. The outline of an integrative, body-to-soul preadaptation theory of disgust, 4. Some specific features of disgust that make it particularly susceptible to laboratory research and particularly appropriate to address some fundamental (...) issues in psychology. In the final section, we outline some new questions that arise from the recent increased interest in disgust in the areas of brain mechanisms, psychopathology, the psychometric approach to the structure of disgust, and disgust and morality. We then indicate some important aspects of disgust that have yet to receive systematic investigation. (shrink)

In an influential article, Anthony Kenny charged that (a) the view of freedom in Descartes’ “1645 letter to Mesland” is incoherent, and (b) that this incoherence was present in Descartes’ thought from the beginning. Against (b), I argue that such incoherence would rather support Gilson’s suspicions that the 1645 letter is dishonest. Against (a), I offer a close reading of the letter, showing that Kenny’s objection seems plausible only if we misconstrue a key ambiguity in the text. I close by (...) defending Descartes against some related worries of my own about the degrees of Cartesian freedom. I conclude that there is really no good reason to deny that Descartes’ view in the 1645 letter is both internally coherent and a genuine explication of the Meditations’ account of freedom. (shrink)
