J. M. E. McTaggart, in a famous argument, denied the reality of time because he thought that passage or temporal becoming was essential for the existence of time and that passage was a self-contradictory concept. This denial of passage has provoked a vast literature, two of the most important contributions being C. D. Broad’s painstaking defence of passage in his Examination of McTaggart’s Philosophy and D. C. Williams’ dazzling condemnation of it “The Myth of Passage.” -/- A careful reading of (...) these apparently opposed essays reveals that there is a common notion of passage that both philosophers endorse, the successive occurrence of sets of simultaneous events (assuming classical or Newtonian spacetime structure as background). This unexpected agreement provides a notion of the passage of time that, I claim, is lean enough to survive the criticisms of passage-deniers yet robust enough to satisfy the requirements of passage-affirmers. I undertake to describe and defend this notion. -/- . (shrink)

Mark Hinchliff concludes a recent paper, "The Puzzle of Change," with a section entitled "Is the Presentist Refuted by the Special Theory of Relativity?" His answer is "no." I respond by arguing that presentists face great difficulties in merely stating their position in Minkowski spacetime. I round up some likely candidates for the job and exhibit their deficiencies.

The aim of this essay is to introduce philosophers of science to some recent philosophical discussions of the nature and origin of the direction of time. The essay is organized around books by Hans Reichenbach, Paul Horwich, and Huw Price. I outline their major arguments and treat certain critical points in detail. I speculate at the end about the ways in which the subject may continue to develop and in which it may connect with other areas of philosophy.

In his article The Nature, Importance, and Difficulty of Machine Ethics, James H. Moor distinguishes two lines of argument for those who wish to draw a “bright line” between full ethical agents, such as human beings, and “weaker” ethical agents, such as machines whose actions have significant moral ramifications. The first line of argument is that only full ethical agents are agents at all. The second is that no machine could have the presumed features necessary for ethical agency. This paper (...) shows why Moor is mistaken in his refutation of the first line of argument; it also makes a positive case that “weaker” ethical agents are not agents at all. This positive case, however, allows Moor’s rejection of the second line of argument to stand: allowing that there could be moral machines, but that these machines would have to be full moral agents and not merely something that models moral behavior or can be used in morally charged ways.

In this incisive book, Michel de Certeau considers the uses to which social representation and modes of social behavior are put by individuals and groups, describing the tactics available to the common man for reclaiming his own autonomy from the all-pervasive forces of commerce, politics, and culture. In exploring the public meaning of ingeniously defended private meanings, de Certeau draws brilliantly on an immense theoretical literature to speak of an apposite use of imaginative literature.

I present an account of the passage of time and the present in relativistic spacetimes, and I defend these views against recent criticism by Oliver Pooley and Craig Callender.

Some institutional investors are exposed to social norms and public scrutiny. Prior research indicates that these norm-constrained institutions engage in negative screening and invest less in firms operating in ‘sin’ industries. We examine whether social norms also motivate these institutions to engage in positive screening—where they invest more in firms with better corporate social responsibility performance—and CSR-related activism—where they promote improvements in the CSR of existing investees. We find that firms with superior CSR performance have greater ownership by norm-constrained institutions, (...) consistent with positive screening, and we use a natural experiment to establish causality. We also find that increases in the shareholdings of norm-constrained institutions are associated with subsequent improvements in CSR, consistent with activism. Further, we rule out an alternative explanation for our results where the positive screening and activism are ‘profit-driven’ rather than driven by social pressure. Thus, our results suggest that the influence of social norms on stock markets is more pervasive than documented in the prior literature. (shrink)

Richard Arthur and I proposed that the present in Minkowski spacetime should be thought of as a small causal diamond. That is, given two timelike separated events p and q, with p earlier than q, they suggested that the present is the set I+ ∩ I-. Mauro Dorato presents three criticisms of this proposal. I rebut all three and then offer two more plausible criticisms of the Arthur/Savitt proposal. I argue that these criticisms also fail.

Much progress has been made in recent years regarding the mechanisms of targeting of secretory proteins to, and across, the endoplasmic reticulum (ER) membrane. Many of the cellular components involved in mediating translocation across this bilayer have been identified and characterized. Polypeptide domains of secretory proteins, termed signal peptides, have been shown to be necessary, and in most cases sufficient, for entry of preproteins into the lumen of the ER. These NH2‐ terminal segments appear to serve multiple roles in targeting (...) and translocation. The structural features which mediate their multiple functions are currently the subject of intense study. (shrink)

In a recent book, Asymmetries in Time, Paul Horwich presents a systematic account of various temporal asymmetries, including a neo-Reichenbachian account of the (apparent) fact that we know more about the past than the future, the epistemological time asymmetry. I find some obscurities in Horwich's presentation, however, and I argue that when his view is understood in a way that I shall propose, it does represent an advance on Reichenbach's, but it fails to vindicate Horwich's "main point...that our special knowledge (...) of the past derives from the fork asymmetry.

In medieval epistemology, self-examination is intimately tied to the search for a knowledge that transcends the self. Introspection can lead to intellectual and spiritual ascent. The “inward journey” of a poem like Piers Plowman is directed not only inward but also outward and upward, toward the external and transcendent. Self-exploration, however, is not universally depicted as leading to ascent: it is dangerous, beset by narcissistic traps, by the possibility that the self will seem an end sufficient to itself and become (...) the sole and ultimate object of its own attention. The medieval status of self-examination is, in other words, strongly ambivalent, as we see in treatments of that instrument of self-reflection par excellence, the mirror. The story of Narcissus and its cautionary lessons were well known to the later Middle Ages. But medieval authors had access not only to narcissistic mirrors. Holy Scripture and the ordered universe are mirrors reflecting the divine plan, and the self's place within that plan. The human soul is sometimes figured as a mirror in which God can be known. Looking in mirrors we see not only ourselves but a broad range of phenomena beyond the self. (shrink)

: This essay introduces a way of reading the Mengzi (Mencius) that complicates how we understand what Mengzi is recorded as saying. A pragmatic-strategic reading of the Mengzi is developed here, according to which Mengzi attends to and operates under important pragmatic constraints on speech. Based on a close reading of key passages, it is argued that truth-telling and descriptive accuracy are less important to Mengzi than guiding people along the Confucian path. This reading has implications for our understanding of (...) Mengzi’s philosophical positions and his methods of argumentation, as well as for our understanding of philosophical activity in general.

Some elementary properties of tachyons are described and then it is argued that the claim that (T) Tachyons exist, is incompatible with the truth of the Special Theory of Relativity (STR). First it is argued that from T, STR, and the negation of the principle that (Pl) Effect never precedes cause, one can derive a paradoxical conclusion, one of the so-called "causal paradoxes". An obvious response is to affirm (Pl), but then it is argued that (Pl) and (T) entail that (...) STR is false. (shrink)

Wittgenstein's remarks in his Tractatus on mathematics are quite obscure. Benacerraf and Putnam wrote, "In his Tractatus Loqico-Philosophicus, Wittgenstein maintained, following Russell and Frege, that mathematics was reducible to logic." On the other hand, Max Black claims, "Wittgenstein does not regard mathematics as reducible to logic, in the manner of Whitehead and Russell." I offer a detailed commentary upon Wittgenstein's remarks, concluding that his views most likely do not follow those of Frege and Russell. I reject a criticism of Wittgenstein (...) presented by Black but find severe shortcomings in the view I take Wittgenstein to be presenting. (shrink)

In this paper I argue that the clash of the Sellars’ two images is particularly acute in the case of time. In Time and the World Order Sellars seems embarked on a quest to locate manifest time in Minkowski spacetime. I suggest that he should have argued for the replacement of manifest time with the local, path-dependent time of the “scientific image”, just as he suggests that manifest objects must be replaced by their scientific counterparts.

There is a wide-spread belief that we know more about the past than we do about the future. It may be difficult to express the content of this belief exactly and it may turn out that, when we find some precise expression of this belief, it is not so obviously true. I shall assume, however, that there is something to a belief shared not only by eminent philosophers but by cultures wholly distinct from our own, as the following quote indicates.We (...) know where the future is. It’s in front of us. Right? It lies before us—a great future lies before us—we stride forward confidently into it, every commencement, every election year. And we know where the past is. Behind us, right? So that we have to turn around to see it, and that interrupts our progress ever forward into the future, so we don’t really much like to do it. (shrink)

This volume is the record of a symposium on the structer of scientific theories held in urbana, Illinois in the spring of 1969. ofSeven main papers, commentaries, discussions, and a postscript form the bulk of the book. The rest is a nearly 240-page monograph-in-the-guise-of-an-introduction by the editor titled “The Search for Philosophic Understanding of Scientific Theories”.

John Earman's new book,World Enough and Space-Time, is a brisk account of the controversy between space-time absolutists and relationists. The book is intended, one is told, to be “appropriate for use in an upper-level undergraduate or beginning graduate course in the philosophy of science”, but Earman's no-holds-barred approach to the mathematics of space-time theories will have bludgeoned most philosophical readers, undergraduate or beyond, into submission long before it is revealed that Pirani and Williams “have studied the integrability conditions for Born-rigid (...) motions in curved space-times and have shown that space-times of Petrov types II, III, and N do not admit of nonrotating Born-rigid motions”. I say this sadly, because Earman's book is a discerning review of an important literature, and most of its main arguments can be grasped even if some technical details remain out of reach. The more you reach for those details, the more compelling the book will become. (shrink)

Liberal democracy aims to treat all adult citizens as politically equal, at least in ideal cases: Once a citizen is over the age of majority, she is deemed a full-fledged member of the community and in theory has equal standing with all other adult citizens when it comes to making policy and participating in the political realm in general. I consider three questions: (1) Is there any plausible alternative to a standard "all adult citizens have equal political standing" model of (...) democracy that could be drawn from a specifically Confucian valuing of elder members of the community? (2) Insofar as there is a plausible alternative, what might it reveal about differences between how liberalism and Confucianism think of human selves as located in time? (3) What sort of difference would it make if the Confucian valuing of age were implemented via informal social norms, on the one hand, or via explicit institutional mechanisms and procedures, on the other?
