An analysis of student learning with the LISP tutor indicates that while LISP is complex, learning it is simple. The key to factoring out the complexity of LISP is to monitor the learning of the 500 productions in the LISP tutor which describe the programming skill. The learning of these productions follows the power‐law learning curve typical of skill acquisition. There is transfer from other programming experience to the extent that this programming experience involves the same productions. Subjects appear to (...) differ only on the general dimensions of how well they acquire the productions and how well they retain the productions. Instructional manipulations such as remediation, content of feedback, and timing of feedback are effective to the extent they give students more practice programming, and explain to students why correct solutions work.

He was 91 years old. Professor Abe was given a quiet funeral service reserved to family and close friends, according to sources in Kyoto.After the death of his mentor D. T. Suzuki, Abe became a leading exponent of Zen in the West and a (...) driving force in the encounter between Buddhism and Christianity. Abe must be credited with much of the intellectual vitality of this dialogue, as well as its relevance to contemporary social problems.Abe was a tireless exponent of the Buddhist doctrine of emptiness as the standpoint for realizing the True Self, yet was also willing to place this basic Buddhist teaching in dialogue with Christianity. Rejecting the notion that Christianity and Buddhism were either fundamentally similar or completely different, Abe saw in interreligious dialogue an opportunity for the mutual transformation of dialogue partners and pursued dialogue to help Buddhists and Christians in confronting the threat of nihilism in the modern world.In the ruins of postwar Japan, Abe began his studies with Hajime Tanabe at the University of Kyoto, a prominent figure in the Kyoto school of contemporary Zen Buddhist philosophy in Japan. But it was his encounter with Shin'ichi Hisamatsu, another philosopher of Zen at the University of Kyoto, that would be decisive for Abe's turn to Zen. In a series of Zen retreats with Hisamatsu at Myoshinji Temple in western Kyoto, Abe was forced to confront the reality of nihilism within himself and eventually resolve this problem by entering the Zen standpoint of emptiness, wherein the enlightened self arises.At age 40, Abe left Kyoto for New York to study at Union Theological Seminary with two of the most prominent Christian theologians of his day, Paul Tillich and Reinhold Niebuhr. This encounter began a distinguished career of teaching, writing, and, above all, dialogue with leading Christian thinkers, including David Tracy, Langdon Gilkey, Rosemary Radford Ruether, Jurgen Moltmann, and Hans Kung. Abe served as visiting professor at the University of Chicago, Purdue University, Claremont College, Columbia University, Princeton University, the University of Hawai'i, and other schools. In Germany, [End Page 139] Abe taught at Heidelberg, Tubingen, and Munich. In addition to his many Japanese publications, Abe wrote extensively in English. These works include Zen and Western Thought, an award-winning collection of essays, and a ground-breaking reflection on Christian belief in Christ interpreted from a Buddhist perspective, "Kenotic God and Dynamic Sunyata." This essay appeared in conjunction with responses from several Christian and Jewish theologians, making the book itself a dialogue. Abe also engaged Jewish intellectuals with his Buddhist reflection on the Holocaust.In 1984, Abe and John Cobb convened a group of Buddhist and Christian intellectuals from Japan, North America, and Europe for dialogue in depth over a sustained period of time on a number of fundamental issues. He was also a guiding influence on the Society for Buddhist-Christian Studies, which continues his work of dialogue today.Masao Abe is survived by his wife Ikuko Abe, his constant companion in a life of sojourn and dialogue in the West.

This volume gathers essays by fourteen scholars, written to honor Fred Dallmayr and the contributions of his political theory. Stephen F. Schneck's introduction to Dallmayr's thinking provides a survey of the development of his work. Dallmayr's “letting be,” claims Schneck, is much akin to his reading of Martin Heidegger's “letting Being be,” and should be construed neither as a conservative acceptance of self-identity nor as a nonengaged indifference to difference. Instead, he explains, endeavoring to privilege neither identity nor difference, the (...) hermeneutic circle for Dallmayr must also be one of thoroughgoing critique and praxis. And, indeed, what joins together Dallmayr's many essays and explorations, what inheres within his “cosmopolitan” understanding of the contemporary world, and what lends his analyses their imperative, is this same “letting be.” "How many of us, over the last forty years, have opened up this or that book by Fred Dallmayr to acquaint ourselves with a new thinker or intellectual movement? It has happened to me several times. Each time, something else happens too. I become alert again to the distinctive and noble temper expressed in Dallmayr's work. _Letting Be_ consists of a series of essays by leading scholars who articulate and appreciate this temper, particularly as it has found expression in his thought about global politics work over the last two decades. This is a fine study, devoted to a thinker whose temper of critical responsiveness deserves wide emulation." —_William E. Connolly, Krieger-Eisenhower Professor, Johns Hopkins University_ _ _ "These essays constitute a marvelous, extended conversation on how political theory should delineate its future tasks. The reader is treated to a lively debate about a crucial set of questions: what strands of traditional Western political thought offer the best resources today; how do we think more comparatively about the foundations of political life; how do we engage more fruitfully Islamic, Indian, and_ mestizo_ contributions; and how do we best envision cross-cultural dialogue and imagine the shape of a "cosmopolis" in ways that will do greater justice to human dignity and diversity? All in all a rich feast honoring a remarkable man and scholar, Fred Dallmayr." —_Stephen K. White, James Hart Professor, University of Virginia_ “This is not the first Festschrift for Dallmayr, and it may not be the last, but it is the first that begins to be in a position to assess his long career with all its twists and turns. I have never fully understood Dallmayr as a creative thinker in his own right until now, and even when I sensed he was, I couldn't precisely say how. Now I can.” —_C.

ABSTRACT Many historians have traced the accumulation of scientific archives via communication networks. Engines for communication in early modernity have included trade, the extrapolitical Republic of Letters, religious enthusiasm, and the centralization of large emerging information states. The communication between Samuel Hartlib, John Dury, Duke Friedrich III of Gottorf-Holstein, and his key agent in England, Frederick Clodius, points to a less obvious but no less important impetus—the international negotiations of smaller states. Smaller states shaped communication networks in an (...) international (albeit politically and religiously slanted) direction. Their networks of negotiation contributed to the internationalization of emerging science through a political and religious concept of shared interest. While interest has been central to social studies of science, interest itself has not often been historicized within the history of science. This case study demonstrates the co-production of science and society by tracing how period concepts of interest made science international. (shrink)

Major shifts in the field of model theory in the twentieth century have seen the development of new tools, methods, and motivations for mathematicians and philosophers. In this book, John T. Baldwin places the revolution in its historical context from the ancient Greeks to the last century, argues for local rather than global foundations for mathematics, and provides philosophical viewpoints on the importance of modern model theory for both understanding and undertaking mathematical practice. The volume also addresses the impact (...) of model theory on contemporary algebraic geometry, number theory, combinatorics, and differential equations. This comprehensive and detailed book will interest logicians and mathematicians as well as those working on the history and philosophy of mathematics. (shrink)

I argue that the most promising approach to understanding J.J. Gibson's "affordances" takes affordances themselves as ontological primitives, instead of treating them as dispositional properties of more primitive things, events, surfaces, or substances. These latter are best treated as coalescences of affordances present in the environment (or "coalescences of use-potential," as in Sanders (1994) and Hilditch (1995)). On this view, even the ecological approach's stress on the complementary organism/environment pair is seen as expressing a particular affordance relation between the world (...) and the analyst. That the world is parsed in any way among events and objects, perceivers and worlds, etc., reflects equally features of certain real or possible perspectives on the world and features of the world itself. In section 1, I begin by contending that, contrary to the apparent expectations of some in the field, the bare existence of affordances is surely quite uncontroversial. In section 2, I argue that the most reasonable approach to foundational ontology is a relativistic one. In section 3, I address the claim that affordances must be ontologically complemented by effectivities for the sake of completeness, and I shall argue against that claim on grounds that I take to reflect some of Gibson's most important insights. This work will help to clarify the way affordances are to be used in the fourth and final section, where I argue that ontological work, even within special sciences, should not be merely "regional," and that the most attractive general approach to ontological questions is one that is based on affordances, rather than upon things, events, surfaces, and the like.

Subcreative sets, introduced by Blum, are known to coincide with the effectively speedable sets. Subcreative sets are shown to be the complete sets with respect to S-reducibility, a special case of Turing reducibility. Thus a set is effectively speedable exactly when it contains the solution to the halting problem in an easily decodable form. Several characterizations of subcreative sets are given, including the solution of an open problem of Blum, and are used to locate the subcreative sets with respect to (...) the complete sets of other reducibilities. It is shown that q-cylindrification is an order-preserving map from the r.e. T-degrees to the r.e. S-degrees. Consequently, T-complete sets are precisely the r.e. sets whose q-cylindrifications are S-complete. (shrink)

Hrushovski originated the study of “flat” stable structures in constructing a new strongly minimal set and a stable 0-categorical pseudoplane. We exhibit a set of axioms which for collections of finite structure with dimension function δ give rise to stable generic models. In addition to the Hrushovski examples, this formalization includes Baldwin's almost strongly minimal non-Desarguesian projective plane and several others. We develop the new case where finite sets may have infinite closures with respect to the dimension function δ. In (...) particular, the generic structure need not be ω-saturated and so the argument for stability is significantly more complicated. We further show that these structures are “flat” and do not interpret a group. (shrink)

John Taurek has argued that, where choices must be made between alternatives that affect different numbers of people, the numbers are not, by themselves, morally relevant. This is because we "must" take "losses-to" the persons into account (and these don't sum), but "must not" consider "losses-of" persons (because we must not treat persons like objects). I argue that the numbers are always ethically relevant, and that they may sometimes be the decisive consideration.

First published in 1969, this volume presents a survey of the contemporary national education system in Latin American countries. Laurence Gale describes the uneven provision of schools for different sections of the community and the problems which arise with the racial, cultural and geographical difficulties. He examines the main features in education throughout Latin America, areas of co-operation and agreement and differences of policy and provision.

This article examines cognitive process models of human sentence comprehension based on the idea of informed search. These models are rational in the sense that they strive to find a good syntactic analysis quickly. Informed search derives a new account of garden pathing that handles traditional counterexamples. It supports a symbolic explanation for local coherence as well as an algorithmic account of entropy reduction. The models are expressed in a broad framework for theories of human sentence comprehension.

I describe a problem about the relations among symmetries, laws and measurable quantities. I explain why several ways of trying to solve it will not work, and I sketch a solution that might work. I discuss this problem in the context of Newtonian theories, but it also arises for many other physical theories. The problem is that there are two ways of defining the space-time symmetries of a physical theory: as its dynamical symmetries or as its empirical symmetries. The two (...) definitions are not equivalent, yet they pick out the same extension. This coincidence cries out for explanation, and it is not clear what the explanation could be.

There is a great deal that might be said about justice in property claims. The strategy that I shall employ focuses attention upon the initial acquisition of property -- the most sensitive and most interesting area of property theory. Every theory that discusses property claims favorably assumes that there is some justification for transforming previously unowned resources into property. It is often this assumption which has seemed, to one extent or another, to be vulnerable to attack by critics of particular (...) justifications of property. Nevertheless, this assumption is frequently left undefended by property theorists, and where it is defended, the defense is often remarkably weak. That some initial claim to property be defensible is required by any theory which holds that certain present distributions may be justified, that certain transfers of property are justified, or that restitution ought to be made for previous injustice in transfer or acquisition. The initial acquisition of property, and its justification, is crucial to the remainder of property theory. (shrink)

While there are numerous differences between the approaches taken by Maurice Merleau-Ponty and James J. Gibson, the basic motivation of the two thinkers, as well as the internal logic of their respective views, is extraordinarily close. Both were guided throughout their lives by an attempt to overcome the dualism of subject and object, and both devoted considerable attention to their "Gestaltist" predecessors. There can be no doubt but that it is largely because of this common cause that the subsequent development (...) of their ideas is so similar. It is not my objective in what follows merely to demonstrate a similarity between two lines of thought. Instead, I will try to show that each approach gains considerably from attention to the other. There are numerous ways to begin such a project, each about as arbitrary as the next. For present purposes, I shall take as of central importance the question of the character of the perceived world, both in relation to the traditionally opposed mental and material "substances", and in relation to its identification and individuation of things vis a vis one another and vis a vis ourselves. This will implicate especially Gibson's "affordances" and Merleau-Ponty's thesis concerning the "materiality of meaning.". (shrink)

Thesis: The exclusion of organized labor/management issues from the principal arenas for business ethics study and discussions needs to be remedied. The paper develops this thesis in three steps: 1) Exclusion: A careful examination of select textbooks, journals, and conferences provides evidence as to the virtual absence of unions and such crucial organized labor/management issues as labor organizing and collective bargaining; 2) Inclusion: A series of brief arguments favoring inclusion of these issues in business ethics based on the notion of (...) privileged institutions, adversarial posturing, the societal benefits, and globalization; 3) Suggestions: Some practical, cooperative initiatives involving the academy, management and labor, such as, labor officials as guest speakers and members of business school committees, internships in labor organizations, training workshops in business ethics for labor leaders, fora for joint management/labor discussions of issues each group faces in the economy and the legislatures.

We use κ-free but not Whitehead Abelian groups to constructElementary Classes (AEC) which satisfy the amalgamation property but fail various conditions on the locality of Galois-types. We introduce the notion that an AEC admits intersections. We conclude that for AEC which admit intersections, the amalgamation property can have no positive effect on locality: there is a transformation of AEC's which preserves non-locality but takes any AEC which admits intersections to one with amalgamation. More specifically we have: Theorem 5.3. There is (...) an AEC with amalgamation which is not (N₀, N₁)-tame but is 2(N0, ∞)-tame; Theorem 3.3. It is consistent with ZFC that there is an AEC with amalgamation which is not (≤ N₂, ≤ N₂)-compact. (shrink)

This paper examines two different, but closely related, classes of problems. The first part deals with whistleblowers, and the difficulties and dangers that they have often faced, although their actions, in the rare cases where they become necessary, are indispensable for the maintenance of honest science. The problems are illustrated by discussion of several specific cases from 1960 to 1990. The second part deals with problems that face many young scientists today, and the stresses to which they are exposed in (...) an increasingly competitive atmosphere. There are powerful pressures for premature publication, and many gifted scientists are driven to spend an inordinate amount of time in writing grant applications that are turned down for lack of funds, while receiving high praise from reviewers. Correction of conditions is an important matter for science policy; it is also important, among other things, to relieve pressures that would tend to encourage deviations from the standards necessary for trustworthy science.

Previous discussions of addiction have often focused on the question of whether addiction is a disease. This discussion distinguishes that question – the disease question – from the question of whether addiction is a disability. I argue that, however one answers the disease question, and indeed on almost any credible account of addiction, addiction is a disability. I then consider the implications of this view, or why it matters that addiction is a disability. The disease model of addiction has led (...) many to see addiction as primarily a medical problem, and to make medical treatment of the addicted person the first priority in addressing addiction. Once addiction is viewed as a disability, different concerns are foregrounded. The problem of addiction resides not only in the addicted person, but also in the social environment in which the addicted person finds herself. The fundamental ethical question about addiction is not how addicted persons can be treated or otherwise changed, but how a just society can make reasonable accommodations for addicted persons.

We give a general account of the goals of axiomatization, introducing a variant on Detlefsen’s notion of ‘complete descriptive axiomatization’. We describe how distinctions between the Greek and modern view of number, magnitude, and proportion impact the interpretation of Hilbert’s axiomatization of geometry. We argue, as did Hilbert, that Euclid’s propositions concerning polygons, area, and similar triangles are derivable from Hilbert’s first-order axioms. We argue that Hilbert’s axioms including continuity show much more than the geometrical propositions of Euclid’s theorems and (...) thus are an immodest complete descriptive axiomatization of that subject.

In particular, we discuss how problems in model theory motivated new techniques in model theory, for example classifying theories by their potential (consistently with Zermelo–Fraenkel set theory with the axiom of choice (ZFC)) spectrum of cardinals in which there is a universal model. Two other examples are the study (with Malliaris) of the Keisler order leading to a new ZFC result on cardinal invariants and attempts to clarify the “main gap” by reducing the (...) dependence of certain versions on (highly independent) cardinal arithmetic.

How do I live a good life, one that is deeply personal and sensitive to others? John T. Lysaker suggests that those who take this question seriously need to reexamine the work of Ralph Waldo Emerson. In philosophical reflections on topics such as genius, divinity, friendship, and reform, Lysaker explores "self-culture" or the attempt to remain true to one's deepest commitments. He argues that being true to ourselves requires recognition of our thoroughly dependent and relational nature. Lysaker guides readers (...) from simple self-absorption toward a more fulfilling and responsive engagement with the world. (shrink)

I try in this essay to accomplish two things. First I offer some first thoughts toward a clarification of the ethical foundations of private property rights that avoids pitfalls common to more strictly Lockean theories, and is thus better prepared to address arguments posed by critics of standard private property arrangements. Second, I'll address one critical argument that has become pretty common over the years. While versions of the argument can be traced back at least to Pierre Joseph Proudhon, I'll (...) focus on a formulation given it by Jeremy Waldron. The basic idea is that the only sound arguments for private property rights lead to the conclusion that society has an obligation to insure that every citizen possess private property. In Waldron's formulation, what is justifiable is a general, rather than a special, right to private property. I shall try to suggest that this conclusion is unwarranted. (shrink)

As complicated an affair as it may be to give a fully acceptable general characterization of professional codes of ethics that will capture every nuance, one theme that has attracted widespread attention portrays them as contrivances whose primary function is to secure certain obligations of professionals to clients, or to the external community. In contrast to such an "externalist" characterization of professional codes, it has occasionally been contended that, first and foremost, they should be understood as internal conventions, adopted among (...) professionals as a device for securing the "interests" of the professionals themselves. In what follows, I will argue that both of these lines are incomplete. As important as service to the community and the interests of professionals may be in the full understanding of the multiple role that "codes of ethics" play in many professions, it is equally important to see them as expressive of the romance of a profession. Professional codes should be understood not only in terms of their utility to the community, or in terms of their utility to practitioners, but as expressions of callings. Analyses of professional codes of ethics that do not take into consideration their role in evoking the romance of a professional calling are thus not entirely adequate. Professional standards and codes can be fully understood only if one appreciates that they are designed to contribute to and evoke feelings of dignity, self-worth-and, for better or for worse, even the superiority--of the professionals themselves; the code may seem to them to express essential features of what the profession really is.

This is the first part of a two-part article in which we defend the thesis of Humean Supervenience about Laws of Nature (HS). According to this thesis, two possible worlds cannot differ on what is a law of nature unless they also differ on the Humean base. The Humean base is easy to characterize intuitively, but there is no consensus on how, precisely, it should be defined. Here in Part I, we present and motivate a characteriza- tion of the Humean (...) base that, we argue, enables HS to capture what is really stake in the debate, without taking on extraneous commitments.

Christian responses to the developing field of evolutionary psychology tend to be defensive, focusing on the task of showing that Christians have not beenpresented with any reason to abandon any central beliefs of the Christian faith. A more positive response would seek to show that evolutionary psychologycan provide some sort of epistemic support for one or more distinctively Christian doctrines. This paper is an attempt to supply such a response by focusing on the distinctively Christian doctrine of original sin, which (...) presents itself as an especially likely candidate for support from evolutionary psychology. I consider five versions of the doctrine in order of increasing content, arguing that all but the last can receive such support. However, in order to argue for the fourth version (which includes the doctrine traditionally described as “original guilt”), I enlist the aid of a Molinist understanding of divine providence. A consequence of this application of Molinism is that God holds us morally accountable, not only for what we actually do, but also for what we would do in any non-actual conditions, and that He acts on His knowledge of what we would do in such conditions. Because many may find this consequence problematic, I also argue that it is both morally acceptableand necessary for the perfection of the relationship between God and human beings. The last version of original sin that I consider insists that it must be thecausal product of the first sin of the first human being(s), but I argue that this is not a reasonable alternative if original sin is to be equated with behavioraltendencies inherited from an evolutionary ancestry.

In Anarchy, State and Utopia, Robert Nozick argues, first, that free-market anarchism is unstable -that it will inevitably lead back to the state; and, second, that without a certain "redistributive" proviso, the model is unjust. If either of these things is the case, the model defeats itself, for its justification purports to be that it provides a morally acceptable alternative to government (and therefore to the state). I argue, against Nozick's contention, that his "dominant protection agency" neither meets his monopoly (...) condition for statehood nor need run afowl of his redistributive requirement. This being the case, his argument against free market anarchism fails. (shrink)

The existence of "undermining futures" appears to show that a contradiction can be deduced from the conjunction of Humean supervenience (HS) about chance and the Principal Principle. A number of strategies for rescuing HS from this problem have been proposed recently. In this paper, a novel way of defending HS from the threat is presented, and it is argued that this defense has advantages not shared by others. In particular, it requires no revisionism about chance, and it is equally available (...) to defenders of HS who hold HS to be necessary and those who hold it to be contingent. (shrink)

We study when classes can have the disjoint amalgamation property for a proper initial segment of cardinals. Theorem A For every natural number k, there is a class $K_k $ defined by a sentence in $L_{\omega 1.\omega } $ that has no models of cardinality greater than $ \supset _{k - 1} $ , but $K_k $ has the disjoint amalgamation property on models of cardinality less than or equal to $\mathfrak{N}_{k - 3} $ and has models of cardinality $\mathfrak{N}_{k (...) - 1} $ . More strongly, we can have disjoint amalgamation up to $\mathfrak{N}_\alpha $ for α > ω, but have a bound on size of models. Theorem B For every countable ordinal a, there is a class $K_\alpha $ defined by a sentence in $L_{\omega 1.\omega } $ that has no models of cardinality greater than $ \supset _{\omega 1} $ , but K does have the disjoint amalgamation property on models of cardinality less than or equal to $\mathfrak{N}_\alpha $ . Finally we show that we can extend the $\mathfrak{N}_\alpha $ to $ \supset _\alpha $ in the second theorem consistently with ZFC and while having $\mathfrak{N}_i \ll \supset _i $ for 0 > i < α. Similar results hold for arbitrary ordinals α with |α|= K and $L_{k + ,\omega } $. (shrink)

Studies in the neurobiological underpinnings of social information processing bypsychologists, neurobiologists, psychiatrists, radiologists, and neurologists, using methods thatrange from brain imaging techniques to comparative analyses.

I elaborate and defend an interpretation of Leibniz on which he is committed to a stronger space-time structure than so-called Leibnizian space-time, with absolute speeds grounded in his concept of force rather than in substantival space and time. I argue that this interpretation is well-motivated by Leibniz's mature writings, that it renders his views on space, time, motion, and force consistent with his metaphysics, and that it makes better sense of his replies to Clarke than does the standard interpretation. Further, (...) it illuminates the way in which Leibniz took his physics to be grounded in his metaphysics. (shrink)

This paper contains portions of Baldwin’s talk at the Set Theory and Model Theory Conference and a detailed proof that in a suitable extension of ZFC, there is a complete sentence of \ that has maximal models in cardinals cofinal in the first measurable cardinal and, of course, never again.

This presentation of a system of propositional logic is a foundational paper for systems of illocutionary logic. The language contains the illocutionary force operators '' for assertion and ' ' for supposition. Sentences occurring in proofs of the deductive system must be prefixed with one of these operators, and rules of take account of the forces of the sentences. Two kinds of semantic conditions are investigated; familiar truth conditions and commitment conditions. Accepting a statement A or rejecting A commits a (...) person to accepting some statements (the symbol '' marks this value), to rejecting some statements (), and will leave the person uncommitted with respect to others (). Commitment valuations assign the values to sentences of ; such a valuation is conceived as reflecting the beliefs/knowledge of a particular person. This paper explores the relations between truth conditions and commitment conditions, and between semantic concepts defined in terms of these conditions. (shrink)

This is a fundamental re-assessment of the world-view of the alchemists, natural philosophers and intelligencers of the mid 17th century. Based almost entirely upon the extensive and hitherto little-researched manuscript archive of Samuel Hartlib, it charts and contextualises the personal and intellectual history of Johann Moriaen (c.1592-1668), a Dutch-German alchemist and natural philosopher. Moriaen was closely acquainted with many of the leading thinkers and experimenters of his time, including René Descartes, J.A. Comenius, J.R. Glauber and J.S. KÃ1⁄4ffler. His detailed reports (...) of relations with these figures and his response to their work provide a uniquely informed insight into the world of alchemy and natural philosophy. This study also illuminates the nature and mechanisms of intellectual and technological exchanges between Germany, The Netherlands and England. (shrink)

I propose understanding CP-law statements as statements that assert the existence of vague statistical laws, not by fully specifying the contents of those laws, but by picking them out via a description that is both self-referential and self-locating. I argue that this proposal validates many common assumptions about CP-laws and correctly classifies many examples of putative CP-laws. It does this while avoiding the most serious worries that motivate some philosophers to be skeptical of CP-laws, namely the worry that they lack (...) non-trivial truth conditions and that it is impossible for empirical evidence to disconfirm them.

The existence of “undermining futures” appears to show that a contradiction can be deduced from the conjunction of Humean supervenience about chance and the Principal Principle. A number of strategies for rescuing HS from this problem have been proposed recently. In this paper, a novel way of defending HS from the threat is presented, and it is argued that this defense has advantages not shared by others. In particular, it requires no revisionism about chance, and it is equally available to (...) defenders of HS who hold HS to be necessary and those who hold it to be contingent. (shrink)
