We report two experiments in which participants had to judge the time of occurrence of a stimulus relative to a clock. The experiments were based on the control condition used by Libet, Gleason, Wright, and Pearl [Libet, B., Gleason, C. A., Wright, E. W., & Pearl, D. K. . Time of conscious intention to act in relation to onset of cerebral activities : The unconscious initiation of a freely voluntary act. Brain 106, 623–642] to correct for any bias in the (...) estimation of the time at which an endogenous event, the conscious intention to perform a movement, occurred. Participants’ responses were affected systematically by the sensory modality of the stimulus and by the speed of the clock. Such findings demonstrate the variability in judging the time at which an exogenous event occurs and, by extension, suggest that such variability may also apply to the judging the time of occurrence of endogenous events. The reliability of participants’ estimations of when they formed the conscious intention to perform a movement in Libet et al.’s study is therefore questionable. (shrink)

We discuss some recent work by Tim Maudlin concerning Black Hole Information Loss. We argue, contra Maudlin, that there is a paradox, in the straightforward sense that there are propositions that appear true, but which are incompatible with one another. We discuss the significance of the paradox and Maudlin's response to it.

We show a sense in which the spacetime property of effective completeness—a type of “local hole-freeness” or “local inextendibility”—is not stable.

Shortly before his death in 1934, the British historian of chemistry, A. N. Meldrum, published two lengthy articles on Lavoisier's early career in science. After a careful investigation of the collection of manuscripts at the Académie des Sciences in Paris and in light of a detailed and penetrating analysis of Lavoisier's published work, Meldrum concluded that as a youth, Lavoisier was concerned with chemistry only to the extent that he found it useful for his mineralogical and geological researches. Lavoisier began (...) his career as a mineralogist; he became a chemist only in 1772, the “crucial year” when he turned his attention to chemical theory for its own sake and started his famous course of experiments on the nature of combustion and fixed air. Although some details—notably concerning Lavoisier's early education and geological work—have been added to this account since Meldrum's time, the broad conclusions of Meldrum's study are still generally accepted by historians of the chemical revolution.

The contention that the Homeric epics, and perhaps also the Hesiodic poems and the Homeric Hymns, are the products, directly or at a very short remove, of a tradition of orally improvised poetry is widely accepted as a basic premiss in Homeric criticism. The cogency of the argument depends on the frequency and characteristic use of formulae in the early hexameter poetry, and their rarity in the literature of Classical, Hellenistic, and Roman times, which is known or assumed to have (...) been composed in the study. The reasoning appears to me valid, but in some respects overstated or ambiguously stated in recent publications, and the first fault arises out of the second. (shrink)

The thesis of this paper is that corporate activity can best be understood on analogy with the acitivity of persons. The ground for this analogy lies in the nature of activity itself which is common to both and to find a ground therein an analysis of the features of activity is presented based upon a comparison of activity and process by Alburey Castell. Activity is said to be bi-polar with one pole the purpose or goal to be handled in utilitarean (...) fashion and the other pole concerned with the maintenance of the presuppositions of activity.While any goal chosen will have hypothetical oughts as its conditions, it is argued that the presuppositions of activity are categorical oughts in that they cannot be denied without asserting them. And since one of these presuppositions is freedom of choice, thus giving activity the power to destroy its own possibility, these presuppositions function in the context of practice as categorical norms and are universal in their applicability as preserving the possibility of responsible activity for everyone else as well as myself. All activity whether it be other-regarding or self-regarding (self-interest in the business world) is subject to the norms of its own possibility, its enabling conditions, and this constitutes the moral ground for personal, managerial and a basis for inquiry into corporate responsibility.
