Idealist philosophers have traditionally tried to defend their views by appealing to the claim that nonmental reality is inconceivable. A standard response to this inconceivability claim is to try to show that it is only plausible if one blurs the fundamental distinction between consciousness and its object. I try to rehabilitate the idealistic argument by presenting an alternative formulation of the idealist’s basic inconceivability claim. Rather than suggesting that all objects are inconceivable apart from consciousness, I suggest that it is (...) impossible to conceive of any such object as genuinely existent. This thesis is lent credence by the fact that only in reflective self-consciousness is existence a phenomenological datum. Not only is it the case that we are not ever aware of an object as existing, we do not have a clear understanding of what it would be like to have such an awareness. If this is true, then we have reason to believe that while consciousness exists, the objects of consciousness cannot exist. (shrink)

Thomas Talbott has recently argued in this journal that the three propositions 1) God wills universal salvation 2) God has the power to produce universal salvation and 3) some persons are not saved are inconsistent. I contend that this claim is only true if God has no overriding purposes that would place restrictions on the means God uses to achieve God’s ends. One possible example of such an overriding purpose would be God’s aim to produce the most good. I end (...) by suggesting that while God’s purpose of universal salvation does render the achievement of this end probable, it is by no means necessary. (shrink)

In this paper I argue that the denial of middle knowledge and emphasis on human freedom characteristic of open theism makes the traditional concept of hell even more morally problematic than it would otherwise be. But these same features of open theism present serious difficulties for the view that all will necessarily be saved. I conclude by arguing that the most promising approach for open theists is to adopt a version of contingent, as opposed to necessary, universalism. (Published Online April (...) 7 2006). (shrink)

The structure of communication networks can be more or less “democratic”: networks are less democratic if (a) communication is more limited in terms of characteristic degree and (b) is more tightly channeled to a few specifc nodes. Together those measures give us a two-dimensional landscape of more and less democratic networks. We track opinion volatility across that landscape: the extent to which random changes in a small percentage of binary opinions at network nodes result in wide changes across the network (...) as a whole. If wide and frequent swings of popular opinion are taken as a mark of instability, democratic communication networks prove far more stable than anti-democratic ones. In a fnal section, we consider the democratic or anti-democratic character of networks that respond to volatility by rewiring at random, in a search for community, or in a search for a leader.

Underpinning all the other branches of science, physics affects the way we live our lives, and ultimately how life itself functions. Recent scientific advances have led to dramatic reassessment of our understanding of the world around us, and made a significant impact on our lifestyle. In this book, leading international experts, including Nobel prize winners, explore the frontiers of modern physics, from the particles inside an atom to the stars that make up a galaxy, from nano-engineering and brain research to (...) high-speed data networks. Revealing how physics plays a vital role in what we see around us, this book will fascinate scientists of all disciplines, and anyone wanting to know more about the world of physics today. (shrink)

Here, we analyse some recent applications of set theory to topology and argue that set theory is not only the closed domain where mathematics is usually founded, but also a flexible framework where imperfect intuitions can be precisely formalized and technically elaborated before they possibly migrate toward other branches.

From industrial psychology and occupational therapy to the laboratory bench and scenes of “heroic” fieldwork, there are important connections between the science of labor and the labor of science. Participants in the 2022 Gordon Cain Conference explored how greater attention to these connections might deepen historical understanding of what constitutes “science” and what counts as “labor.” Our conversations circled around themes of vulnerability (of systems, individual bodies, historical testimony), affect (pertaining to historical actors and ourselves), and interdependence (e.g. across (...) human groups, species, political boundaries, and time). For the members of this group, which grew out of a panel discussion, these themes and motivations coalesced around a topical focus on invisibility, which helped us to articulate – in the form of a co-created syllabus – research questions about science and labor from multiple angles pertaining to practice, archival preservation, and scholarly representation. This syllabus is organized into six thematic modules that aim to challenge and historicize the concept of invisible labor by facilitating comparisons across geographic, temporal, conceptual, and disciplinary boundaries. The goals of this collaborative syllabus, in sum, are manifold: we seek to facilitate more inclusive histories of science through critical engagement with “invisibility” and thereby promote a more expansive understanding of what constitutes scientific labor; to highlight the constitutive role of gendered labor practices in the scientific enterprise; to draw attention to interdependencies that make all forms of production (knowledge or material) possible; to elucidate systems of remuneration for scientific labor over the longue durée and through pointed comparisons; and, finally, to promote self-reflexivity about the methods we use to narrate the history of science and make sense of our own labors.

Frierson The whole of philosophy is like a tree. The roots are metaphysics, the trunk is physics, and the branches emerging from the trunk are all the other sciences, which may be reduced to three principal ones, namely medicine, mechanics, (...) and morals. Descartes is well known for his metaphysics and physics, the roots and trunk of his philosophical project. But Descartes's morals are generally neglected, partly because they are so difficult to find. He does not dedicate a major published work to morality. His most direct comments on it are in letters to Princess Elizabeth and Pierre Chanut. The published work that most touches on moral issues is The Passions of the Soul, which is primarily a treatise on the relationship between mind and body. As a result of this lack of primary sources , there have been only a few significant studies of Descartes's moral philosophy in French, and only two major works devoted to it in English. This neglect of Descartes's ethics is unfortunate, not least since ethical concerns sometimes influence his work in other areas. This.. (shrink)

The Framers understood the Constitution to be the fundamental expression of the rule of law over against the arbitrary, intemperate, and unjust “rule of men” that all too frequently existed in the political world, unfortunately both democratic as well as monarchical. Accordingly, the rule of law requires a well functioning political and legal system that includes legislative checks and balances, the separation of power between the President and Congress, an independent judiciary, federalism, etc. What happens when this “Madisonian” constitutional system, (...) designed to express “the deliberate sense of the community,” runs into a Judicial branch that, in effect, claims we live under a Constitution, but the Constitution is what we say it is. Must the Judiciary itself be subject to the rule of law, and the decisions of a constitutional majority, or does their “independence” extend to being independent of the constraints of the rule of law and, thus, decent majority rule? How did the original John Marshall Court answer these questions, and what light do the leading cases and controversies shed on the relationship between the Marshall Court and the Madisonian System? Are we facing a situation of Marshall v. Madison? (shrink)

Albert Einstein's attitude towards quantum mechanics—and statistical physics in general—was a puzzle to many of his contemporaries, and has remained a puzzle to the present. Though he made many significant contributions to statistical physics, he continually refused to regard that branch of science as fundamental. The present essay demonstrates that his attitude towards statistical physics was formed during his earliest investigations—between 1901 and 1903. In particular, it is shown that in Einstein's view, statistical laws are based upon non-statistical assumptions. (...) This view influenced much of his later thinking. A few illustrations are offered, concluding with a discussion of his opposition to quantum mechanics. (shrink)

Classification is an important goal in many branches of mathematics. The idea is to describe the members of some class of mathematical objects, up to isomorphism or other important equivalence, in terms of relatively simple invariants. Where this is impossible, it is useful to have concrete results saying so. In model theory and descriptive set theory, there is a large body of work showing that certain classes of mathematical structures admit classification while others do not. In the present paper, we (...) describe some recent work on classification in computable structure theory.Section 1 gives some background from model theory and descriptive set theory. From model theory, we give sample structure and non-structure theorems for classes that include structures of arbitrary cardinality. We also describe the notion of Scott rank, which is useful in the more restricted setting of countable structures. From descriptive set theory, we describe the basic Polish space of structures for a fixed countable language with fixed countable universe. We give sample structure and non-structure theorems based on the complexity of the isomorphism relation, and on Borel embeddings.Section 2 gives some background on computable structures. We describe three approaches to classification for these structures. The approaches are all equivalent. However, one approach, which involves calculating the complexity of the isomorphism relation, has turned out to be more productive than the others. Section 3 describes results on the isomorphism relation for a number of mathematically interesting classes—various kinds of groups and fields. In Section 4, we consider a setting similar to that in descriptive set theory. We describe an effective analogue of Borel embedding which allows us to make distinctions even among classes of finite structures. Section 5 gives results on computable structures of high Scott rank. Some of these results make use of computable embeddings. Finally, in Section 6, we mention some open problems and possible directions for future work. (shrink)

Matthew D. Eddy and David Knight’s new edition of William Paley’s Natural Theology deserves to become the standard scholarly edition of what is a historically, theologically, and philosophically important work, despite a certain neglect of philosophical issues on the part of the editors.

Science and the humanities share the same kit of working tools, called the world's literature. While the author of this article deals mainly with the scientific and mathematical literature, the reader probably gravitates towards some other branches, but such distinctions were hardly made in the Middle Ages. The American philosopher, Wallace Stevens, in his book The Necessary Angel remarks that at the time of Aristotle, the Greek language had no word to signify literature. The reason is surely that literature had (...) long since been too universal an element in Greece to require a name. We have no name for the smell of air. This all-pervading power of literature is apparent already two generations before Aristotle, when Socrates made his defence against leading the youth of Athens towards atheism. Plato's Apology tells us how Socrates taunted his accuser: “Have you such a low opinion of the judges, that you fancy them so illiterate as not to know these doctrines are found in the books of Anaxagoras which are full of them? And so, my word, the youth are said to be taught them by Socrates, when they can be bought in the book-market for one drachma at most…” (a coin today worth 1.4 pence!). (shrink)

Cela découle d’une position métaéthique particulière qu’il (...) nomme positivisme institutionnel (practice positivism), et que l’on peut définir ainsi : la moralité ordinaire a une priorité délibérative sur les règles et les conventions des pratiques et des institutions sociales pour la simple raison que ces dernières sont dépourvues de toute force morale.

Fifty years ago Ernst Gombrich’s Art and Illusion revolutionized philosophical and scientific study of visual representation by thoughtful -application of research from the modern vision sciences. Since then those sciences – recently including neuroscience – have greatly developed, and it is now common to attempt direct translation of their findings to depiction, even treating its perception as a branch of visual perception.Unfortunately, rather than advancing Gombrich’s project, many of these applications – often reductive in nature – involve elementary logical (...) fallacies. These fallacies are mostly due to overlooking Gombrich’s main idea, that image makers – like other technologists – use natural principles for their own purposes, and that their first purpose is to make artifacts, which are perceived as such. With better context, it should be possible to find more constructive directions for recent cognitive research, related to drawing. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Citizens Without Sovereignty: Equality and Sociability in French Thought, 1670–1789Patrick HenryCitizens Without Sovereignty: Equality and Sociability in French Thought, 1670–1789, by Daniel Gordon; viii & 270 pp. Princeton: Princeton University Press, 1994, $39.50.Under examination here is the early modern period in France from Louis XIV to the French Revolution when kings ruled absolutely and citizens were without sovereignty. Discarding the traditional image of the Enlightenment as the (...) absolute enemy of absolutism, Gordon, in this sense, follows Norbert Elias and Robert Darnton who treat the Enlightenment as part of an elitist and hierarchical establishment. More specifically, as his subtitle indicates, Gordon portrays the invention of a “nonpolitical polis” (p. 6), an ideological social space where, despite political inequality, citizens could practice social equality in a hierarchical régime. The rise of this “nondemocratic egalitarian ethos” (p. 7) brought with it a new cult of sociabilité, a term invented in the eighteenth century to describe the idealization of the private sphere and the practice of social equality.The first chapter, then, ties sociability not to democracy, as in the Habermasian model, but to the absolutism that stimulated it and coexisted with it. A series of five ideal types of sociability depict how men and women, members of the bourgeoisie and the aristocracy, came together—in commerce, public welfare, scientific academies, salons, cafés, public libraries, and various other social situations not protorevolutionary in character—to create a bond among equals [End Page 279] under the ancien régime. In this framework, progress and modernity are born during the absolute monarchy where sociability suggests conviviality rather than class warfare. Every major French novel of the eighteenth century supports Gordon’s refutation of De Toqueville’s surprising statement that “noblemen and bourgeois never met except by chance in private life “in prerevolutionary France” (p. 27).In chapters two and three, Gordon examines the nature of the rules of sociability found in courtesy literature and their functioning as the imagined basis of the newly invented idealized space called société. In addition to analyzing in great detail the nature and frequency of the vocabulary invented to define and describe sociabilité, Gordon discusses sociabilité in the context of natural law theory in Hobbes, Bossuet, and among others, Pufendorf, who wanted to refute Hobbes by showing that self-interest leads humans to establish stable social relations even before government orders them to do so. Holbach surfaces here too for having amalgamated the older language of politeness and the newer language of natural law. In Holbach, as in the Encyclopédie, sociability, based on egalitarian premises of natural law, is nonetheless fully compatible with the hierarchical regime. Among other things, this shows clearly that the philosophes never preached the French Revolution. Striving to eliminate the abuses of despotism and establish equality in private life was not tantamount to working for political equality and the abolition of all rank. In this same vein, Gordon paints the apolitical essence of the private sphere and, by a rigorous study of the seventeenth-century manuals of polite living, shows convincingly (this time against Elias who saw the court as a model of refined behavior) that the salon was indeed a world unto itself, independent of preexisting social hierarchies. Rejecting Paul Hazard’s conception of absolute rupture between seventeenth-century culture and eighteenth-century thought, Gordon destroys the facile dichotomy between seventeenth-century hierarchy and eighteenth-century equality and, once again, admirably depicts the compatibility of Enlightenment and absolutism.If chapters one to three underscore a certain continuity between the seventeenth and eighteenth centuries, chapters four and five explain important changes. It is not, for example, the mere preservation of the idea of sociable communication but rather its new use that is germane in understanding the Enlightenment. Now “conversation” and “civility” no longer had meaning only for an urban elite but had in fact become ideals in all philosophical endeavors including the writing of universal history. Sociable communication had become the defining characteristic of modern nations. In the fourth chapter, by analyzing in detail the works of Jean-Baptiste Suard, Gordon demonstrates the meaning that the writing of universal history in Scotland acquired within the French...

This review essay explores Josiah Young's project of developing a liberatory Pan-Africanism that is attuned to cultural diversity and Victor Anderson's advocacy of postmodern cultural criticism in African-American religious thought. After situating African-American religious thought as a branch of Africana thought, the author examines these two religious thinkers' work as an effort to forge a position on African-American religious thought--including its relation to theology--in an age where even theory is treated as a god that is about to die. At (...) the conclusion, secularism emerges as a religious project that normatively undergirds the methodological dimensions of these works. (shrink)

Professor Rescher finds however, on the contrary, that the literature of the last ten to fifteen years displays a significant cluster of developments in logic that may be called philosophical. Branches of logical theory have (...) been developed with philosophical applications in mind. Foundations have been laid for an exact logic of obligation, preference, choice, command; the traditional problem of universals has been focused from the perspective of mathematical logic; existence, time, tense, change and process is being explored with techniques of logic; literature on the logic of belief, hypothesis and probability is extensive.

The idea of combining logics, structures, and theories has recently been attracting interest in areas as diverse as constraint logic programming, theorem proving, verification, computational linguistics, artificial intelligence and indeed, various branches of logic itself. It would be an exaggeration to claim that these (scattered, and by-and-large independent) investigations have crystallized into an enterprise meriting the title "combined methods"; nonetheless, a number of interesting themes are emerging. This introduction notes some prominent ones and relates them to the papers in this (...) special issue. (shrink)

A review article on Leszek Kołakowski’s, ‘Why is There Something Rather Than Nothing?’ centering on Leibniz’s famous Question.

While game theory has been transformative for decision making, the assumptions made can be overly restrictive in certain instances. In this work, we investigate some of the underlying assumptions of rationality, such as mutual consistency and best response, and consider ways to relax these assumptions using concepts from level-k reasoning and quantal response equilibrium (QRE) respectively. Specifically, we propose an information-theoretic two-parameter model called the quantal hierarchy model, which can relax both mutual consistency and best response while still approximating level-k, (...) QRE, or typical Nash equilibrium behavior in the limiting cases. The model is based on a recursive form of the variational free energy principle, representing higher-order reasoning as (pseudo) sequential decision-making in extensive-form game tree. This representation enables us to treat simultaneous games in a similar manner to sequential games, where reasoning resources deplete throughout the game-tree. Bounds in player processing abilities are captured as information costs, where future branches of reasoning are discounted, implying a hierarchy of players where lower-level players have fewer processing resources. We demonstrate the effectiveness of the quantal hierarchy model in several canonical economic games, both simultaneous and sequential, using out-of-sample modelling. (shrink)

Gordon Kaufman's “constructive theology” can easily be taken out of context and misunderstood or misrepresented as a denial of God. It is too easily overlooked that in his approach everything is an imaginary construct given no immediate ontological status—the self, the world, and God are “products of the imagination.” This reflects an influence, not only of theories on linguistic and cultural relativism, but also of Kant's “ideas of pure reason.” Kaufman is explicit about this debt to Kant. But I (...) argue there are other aspects of Kant's legacy implicit in his method. These center around Kaufman's engagement with “observed patterns” in nature. With Paul Tillich's aid, I bring this neglected issue to the fore and argue that addressing it allows one to more readily capitalize upon the Kantian influence in Kaufman's method. This, in turn, encourages one to tap more deeply into the epistemic underpinnings of Kaufman's approach to the science–religion dialogue. (shrink)

Most of us would agree with the almost trite saying that “life is a journey”. Of course it is, unless it ends tragically at birth, and even then it is a very short journey.

Many journeys seem to be in an almost straight line while others meander from one place to another, changing direction and alternating goals, sometimes zigging back (...) and forth. I have had many wonderful journeys in my life; the choice to change career aspirations from engineering to medicine, the choice the study in medicine in Scotland, the choice to focus on geriatrics and then the choice to branch out into medical ethics to add more depth to clinical medicine.
