_Time, Memory, and the Verbal Arts: Essays on the Thought of Walter Ong_ Edited by Dennis L. Weeks and Jane Hoogestraat Selinsgrove: Susquehanna University Press, 1999 ISBN: 1-57591-009-8 247 pp.

This volume contains eighteen papers, three with new postscripts, that were written over the past 35 years. Five of the papers have not been previously published. Together they provide a comprehensive account of modal reality—the realm of possible worlds—from a Humean perspective, with excursions into neighboring topics in metaphysics. Part 1 sketches an account of reality as a whole, both the mathematical and the modal, defending a form of plenitudinous realism: every consistent proposition is true of some portion of reality. (...) Part 2 presents and defends a realist theory of concrete possible worlds with an absolute ontological distinction between the actual and the merely possible. Part 3 presents and defends a Humean account of modal plenitude, formulating and endorsing principles of recombination, of plenitude of possible structures, and of plenitude of alien contents. Part 4 applies the Humean account to truthmaking, mereology, spacetime, and quantities. I argue that holding fast to Humean strictures leads to views that differ in radical ways from those put forth by contemporary metaphysicians. (shrink)

It is a central aspect of our ordinary concept of time that history unfolds and events come into being. It is only natural to take this seriously. However, it is notoriously difficult to explain further what this `becoming' consists in, or even to show that the notion is consistent at all. In this article I first argue that the idea of a global temporal ordering, involving a succession of cosmic nows, is not indispensable for our concept of time. Our experience (...) does not support the existence of global simultaneity and arguments from modern physics further support the conclusion that time should not be seen as a succession of cosmic nows. Accordingly, I propose that if we want to make sense of becoming we should attempt to interpret it as something purely local. Second, I address the question of what this local becoming consists in. I maintain that processes of becoming are nothing but the successive happening of events, and that this happening of events consists entirely in the occurring of these events at their own spacetime locations. This leads to a consistent view of becoming, which is applicable even to rather pathological spacetimes. (shrink)

One of the characteristics of Big Data is that it often involves “imperfect” information. This paper examines the work of John Graunt in the tabulation of diseases in London and the development of a life table using the “imperfect data” contained in London’s Bills of Mortality in the 1600s. London’s Bills of Mortality were Big Data for the 1600s, as they included information collected over time, the depth and accuracy of which improved gradually. The main shortcoming of the data available (...) at the time was its nonuniform upkeep and the lack of depth of variables included at its outset. Due to these characteristics, it provides a perfect model for the examination of imperfect Big Data, as it has been analyzed, criticized, and interpreted repeatedly since the 1600s. (shrink)

: The transplantation of adult human neural stem cells into prenatal non-humans offers an avenue for studying human neural cell development without direct use of human embryos. However, such experiments raise significant ethical concerns about mixing human and nonhuman materials in ways that could result in the development of human-nonhuman chimeras. This paper examines four arguments against such research, the moral taboo, species integrity, "unnaturalness," and human dignity arguments, and finds the last plausible. It argues that the transfer of human (...) brain or retinal stem cells to nonhuman embryos would not result in the development of human-nonhuman chimeras that denigrate human dignity, provided such stem cells are dissociated. The article provides guidelines that set ethical boundaries for conducting such research that are consonant with the requirements of human dignity. (shrink)

The most commonly heard proposals for reducing possible worlds to language succumb to a simple cardinality argument: it can be shown that there are more possible worlds than there are linguistic entities provided by the proposal. In this paper, I show how the standard proposals can be generalized in a natural way so as to make better use of the resources available to them, and thereby circumvent the cardinality argument. Once it is seen just what the limitations are on these (...) more general proposals, it can be clearly seen where the real difficulty lies with any attempt to reduce possible worlds to language. Roughly, the difficulty is this: no actual language could have the descriptive resources needed to represent all the ways things might have been. I conclude by arguing that this same difficulty spells doom for any nominalist or conceptualist proposal for reducing possible worlds. (shrink)

We claim that scientists working with deep learning (DL) models exhibit a form of pragmatic understanding that is not reducible to or dependent on explanation. This pragmatic understanding comprises a set of learned methodological principles that underlie DL model design-choices and secure their reliability. We illustrate this action-oriented pragmatic understanding with a case study of AlphaFold2, highlighting the interplay between background knowledge of a problem and methodological choices involving techniques for constraining how a model learns from data. Building successful models (...) requires pragmatic understanding to apply modelling strategies that encourage the model to learn data patterns that will facilitate reliable generalisation. (shrink)

In this chapter, I evaluate various conceptions of distance. Of the two most prominent, one takes distance relations to be intrinsic, the other extrinsic. I recommend pluralism: different conceptions can peacefully coexist as long as each holds sway over a distinct region of logical space. But when one asks which conception holds sway at the actual world, one conception stands out. It is the conception of distance embodied in differential geometry, what I call the Gaussian conception. On this conception, all (...) fundamental facts about distance are “local” facts.” But there is a problem: the Gaussian conception, notwithstanding its mathematical and physical credentials, appears metaphysically suspicious on Humean grounds. In the final section, I suggest that the Gaussian conception can be given a sound metaphysical footing in terms of non-standard analysis. (shrink)

Despite renewed interest in T.H. Green’s social and political theory, little attention has as yet been given to his metaphysics and epistemology — even more neglected, though, are his views on logical matters. It is unclear why this is. I suspect that the obscurity of his discussion has much to do with it. Green routinely refers to writers in whom there is little interest today; and a good deal of effort is required to penetrate his technical vocabulary. Still, I believe (...) we miss something important when we ignore his specifically logical writings. Green has much to say about classical syllogism and its influence on his contemporaries. And, while the discussion is always grounded in his own idealist theory of knowledge, Green’s analysis often reveals surprising aspects of the problem being considered. In what follows, then, I shall consider one such analysis: his account of the logical/epistemological doctrine of Sir William Hamilton and H.L. Mansel — individuals whose writings, in Green’s eyes, made apparent all that was wrong with the “formal logic” of the day. (shrink)

Brink. Perfectionism and the Common Good: Themes in the Philosophy of T. H. Green. Oxford: Clarendon Press, 2003. Pp. xiv + 139. Cloth, $27.50. The British idealists have not fared well during the past century. Still, there has been in recent years a renewed interest in the (...) movement's principal figures: F. H. Bradley and T. H. Green. And, while Bradley's polemical style has found a wider audience, Green's work—especially his Principles of Political Obligation—appears to have had the steadier following. Lesser known than Green's political writing, though, is his longer and more difficult Prolegomena to Ethics. And David O. .. (shrink)

The "War" in science is largely the discussion between those who believe that science is above criticism and those who do not. After the Science Wars is a collection of essays by leading philosophers and scientists, all attempting to bridge interdisciplinary gulfs in this discussion.

By means of a comprehensive and penetrating examination of the main elements of Epicurean ethics, Phillip Mitsis forces us to reevaluate this widely misunderstood figure in the history of philosophy.

This paper is a rejoinder to Thaddeus Metz’s article “Censure Theory Still Best Accounts for Punishment of the Guilty: Reply to Montague.” In his article, Metz attempts to answer objections to censure theory that I had raised previously. I argue in my rejoinder that Metz’s defense of censure theory remains seriously problematic despite what he says in his reply.

A little-discussed aspect of the “conservative” position on abortion involves the claim that human beings exist at all stages of gestation — that even the human fertilized ovum is a human being. There are good reasons of both a practical and theoretical nature why this particular idea has received so little attention in the abortion controversy. On the practical side there is the fact that zygotes are rarely if ever the subjects of abortion decisions; and on the theoretical side, there (...) is the prima facie implausibility of the idea itself — an implausibility stemming from the fact that human zygotes possess none of the features that distinguish clear-cut examples of human beings from other living things.I would like to suggest, however, that there are good reasons — again both practical and theoretical — for examining with some care the idea that human zygotes are human beings. For even if this idea is not central to the abortion controversy, it has clear relevance to the morality of using intrauterine devices as a means of procreation control. (shrink)

Peter van Inwagen attempts to demonstrate the apparent incompatibility of free will and indeterminism through an imaginative thought experiment. He imagines God repeatedly rolling the world back to its state one minute prior to the performance of an undetermined, putatively free action and then letting it go forward again. Van Inwagen argues that the outcome most friendly to the supposition that the agent acted freely, in which she does otherwise about half the time, is one which apparently shows that her (...) original act was a matter of chance, and thus not free. I argue that neither this outcome nor any other implies that her action was not free. (shrink)
