Modal Platonism utilizes "weak" logical possibility, such that it is logically possible there are abstract entities, and logically possible there are none. Modal Platonism also utilizes a non-indexical actuality operator. Modal Platonism is the EASY WAY, neither reductionist nor eliminativist, but embracing the Platonistic language of abstract entities while eliminating ontological commitment to them. Statement of Modal Platonism. Any consistent statement B ontologically committed to abstract entities may be replaced by an empirically equivalent modalization, MOD(B), not so ontologically committed. This (...) equivalence is provable using Modal/Actuality Logic S5@. Let MAX be a strong set theory with individuals. Then the following Schematic Bombshell Result (SBR) can be shown: MAX logically yields [T is true if and only if MOD(T) is true], for scientific theories T. The proof utilizes Stephen Neale's clever model-theoretic interpretation of Quantified Lewis S5, which I extend to S5@. (shrink)

In spite of the work of Gödel and Cohen, which showed the undecidability of the Generalized Continuum Hypothesis from the axioms of set theory, the problem still remains to decide GCH on the basis of new axioms. It is almost 100 years since Cantor first conjectured the Continuum Hypothesis, yet we seem to be no closer to determining its truth. Nevertheless, it is a sound methodological principle that given any undecidable set-theoretical statement, we should search for “other axioms of set (...) theory which a more profound understanding of the concepts underlying logic and mathematics would enable us to recognize as implied by these concepts”.

. In this paper, I attempt to dissolve the theism/atheism boundary. In the first part, I consider last things, according to mainstream science. In the second part, I define the Natural God as the Force of Nature—evolving, unifying, maximizing—and consider Its relation to last things. Finally, I discuss our knowledge of the Natural God and Its relevance to our personal lives. I argue that we can know the Natural God through scientific reason combined with global intuition, and that this knowledge, (...) from the perspective of last things, may help us achieve universal love, ethical action, and personal salvation.

A number of results have been obtained concerning Borel structures starting with Silver and Friedman followed by Harrington, Shelah, Marker, and Louveau. Friedman also initiated the model theory of Borel (in fact totally Borel) structures. By this we mean the study of the class of Borel models of a given first-order theory. The subject was further investigated by Steinhorn. The present work is meant to go further in this direction. It is based on the assumption that the study (...) of the class of, say, countable models of a theory reduces to analyzing a single $\omega_1$-saturated model. The question then arises as to when such a model can be totally Borel. We present here a partial answer to this problem when the theory under investigation is superstable. (shrink)

Call the norms of inquiry zetetic norms. How are zetetic norms related to epistemic norms? At first glance, they seem quite closely connected. Aren't epistemic norms norms that bind inquirers qua inquirers? And isn't epistemology the place to look for a normative theory of inquiry? While much of this thought seems right, this paper argues that the relationship between the epistemic and the zetetic is not as harmonious as one might have thought and liked. In particular, this paper argues that (...) some familiar contemporary epistemic norms are in tension with, and even in conflict with, central zetetic norms. (shrink)

Katzav and Vaesen have argued that control by analytic philosophers of key journals, philosophy departments and at least one funding body plays a substantial role in explaining the emergence of analytic philosophy into dominance in the Anglophone world and the corresponding decline of speculative philosophy. They also argued that this use of control suggests a characterisation of analytic philosophy as, at the institutional level, a sectarian form of critical philosophy. I test these hypotheses against data about philosophy job hires at (...) key philosophy departments in the USA during the period 1930-1979, and against data about PhD completions during the period 1956-1965. I argue, further, that Katzav and Vaesen’s hypotheses can fully explain the data and are more fully able to do so than are some other key accounts of the emergence of analytic philosophy in the USA.

Philosophy and Phenomenological Research, EarlyView.

In this paper I look at belief and degrees of belief through the lens of inquiry. I argue that belief and degrees of belief play different roles in inquiry. In particular I argue that belief is a “settling” attitude in a way that degrees of belief are not. Along the way I say more about what inquiring amounts to, argue for a central norm of inquiry connecting inquiry and belief and say more about just what it means to have an (...) inquiry or question settled.

In this paper I argue that there is a class of attitudes that have questions (rather than propositions or something else) as contents.

What I call the dynamics of reason is a post-Kuhnian approach to the history and philosophy of science articulating a relativized and historicized version of the Kantian conception of the rationality and objectivity of the modern physical sciences. I here discuss two extensions of this approach. I argue that, although the relativized standards of rationality in question change over time, the particular way in which they do this still preserves the trans-historical rationality of the entire process. I also make a (...) beginning in extending my historical narrative from purely intellectual history (both philosophical and scientific) to the wider cultural context. (shrink)

I outline the theoretical framework of, and three research programs within American speculative philosophy of science during the period 1900-1931. One program applies verificationism to research in psychology, one investigates the methodology of research programs, and one analyses scientific explanation and other scientific concepts. The primary sources for my outline are works by Morris Raphael Cohen, Grace Andrus de Laguna, Theodore de Laguna, Edgar Arthur Singer Jr., Harold Robert Smart, and Marie Collins Swabey. I also use my outline to provide (...) a partial comparison of American speculative philosophy of science and 1930s logical positivism. My comparison suggests that logical positivism was a proposal for substantially narrowing down and winding back American philosophy of science and was based on positions that were already problematized in the American context. -/- .

In the contemporary debate on free will, most philosophers assume that the defense of libertarianism implies the defense of the notion of alternative possibilities. This article discusses this presupposition by showing that it is possible to build a libertarianism without alternative possibilities, apparently more robust than libertarianism with alternative possibilities. Inspired by Bergson, this nonclassical libertarianism challenges the idea that all causation implies the actualization of a predetermined possibility (an idea shared by determinism and classical libertarianism). Moreover, it challenges the (...) idea that free will is a mere choice between prefixed possibilities: for this libertarianism, free will is the result of a creative process of the mind—an entirely causal process whose outcome is not, however, predetermined. This nonclassical libertarianism describes the process of forming a will in a more realistic way than classical libertarianism does. Furthermore, it is not threatened by the problem of chance.

As technology improves, artificial systems are increasingly able to behave in human-like ways: holding a conversation; providing information, advice, and support; or taking on the role of therapist, teacher, or counsellor. This enhanced behavioural complexity, we argue, encourages deeper forms of affective engagement on the part of the human user, with the artificial agent helping to stabilise, subdue, prolong, or intensify a person's emotional condition. Here, we defend a fictionalist account of human/AI interaction, according to which these encounters involve an (...) elaborate practise of imaginative pretence: a make-believe in which the artificial agent is attributed a life of its own. We attend, specifically, to the temporal characteristics of these fictions, and to what we imagine artificial agents are doing when we are not looking at them. (shrink)

This paper introduces the philosophy of Grace Andrus de Laguna in order to renew interest in it. I show that, in the 1910s and 1920s, she develops ideas and arguments that are also found playing key roles in the development of analytic philosophy decades later. Further, I describe her sympathetic, but acute, criticism of pragmatism and Heideggerian ontology, and situate her work in the tradition of American, speculative philosophy. Before 1920, we will see, de Laguna appeals to multiple realizability to (...) undermine reductionism in science, to support perspectival, scientific realism and, with help from a private language argument, to favour the view that mental states are classified by behavioural, teleological roles over what came to be called ‘type physicalism’. Her view of speech, mostly developed in the 1920s, tells us that its primary role is coordinating group behaviour rather than expressing thoughts. Belief is understood in terms of its causal role, including its causal relations to other kinds of mental states, when coordinating group behaviour. Thought is similarly understood. In developing her theory of mind, de Laguna rejects the pragmatist claims that belief can be reduced to dispositions to behaviour and that thought’s function is to address specific, rather than general, problems. She also favours meaning holism and rejects the analytic–synthetic distinction. In later work, de Laguna argues that individuals’ activity of self-maintenance brings universals, conceived of as irreducible potentialities, into being and makes them increasingly determinate. Further, she identifies the existence of all individuals with forms of self-maintenance and takes the existence of people to include maintenance of the cultural world. Such a unified treatment of existence, she holds, permits making its evolution intelligible. Heidegger’s view of being is rejected for not permitting this. All de Laguna’s work, we will see, fits a vision of philosophy as the systematic, imaginative and naturalistic examination of being as well as a source of criticism of science. (shrink)

Grace A. de Laguna was an American philosopher of exceptional originality. Many of the arguments and positions she developed during the early decades of the twentieth century later came to be central to analytic philosophy. These arguments and positions included, even before 1930, a critique of the analytic-synthetic distinction, a private language argument, a critique of type physicalism, a functionalist theory of mind, a critique of scientific reductionism, a methodology of research programs in science and more. Nevertheless, de Laguna identified (...) herself as a defender of the speculative vision of philosophy, a vision which, in her words, “analytic philosophy condemns.” I outline her speculative vision of philosophy as well as what is, in effect, an argument she offers against analytic philosophy. This is an argument against the view that key parts of established opinion, e.g., our best theoretical physics or most certain common sense, should be assumed to be true in order to answer philosophical questions. I go on to bring out the implications of her argument for the approaches to philosophy of Bertrand Russell, Willard V. Quine and David Lewis, and I also compare the argument to recent, related arguments against analytic philosophy. I will suggest that de Laguna offers a viable critique of analytic philosophy and an alternative approach to philosophy that meets this critique. (shrink)

Scientific disagreements are an important catalyst for scientific progress. But what happens when scientists disagree amidst times of crisis, when we need quick yet reliable policy guidance? In this paper we provide a normative account for how scientists facing disagreement in the context of ‘fast science’ should respond, and how policy makers should evaluate such disagreement. Starting from an argumentative, pragma-dialectic account of scientific controversies, we argue for the importance of ‘higher-order evidence’ (HOE) and we specify desiderata for scientifically relevant (...) HOE. We use our account to analyze the controversy about the aerosol transmission of COVID-19. (shrink)

Martin Buber: The Life of Dialogue , the first study in any language to provide a complete overview of Buber's thought, remains the definitive guide to the full range of his work and the starting point for all modern Buber scholarship. As well as summarizing Buber's early intellectual development and attitudes - his mysticism, his youthful existentialism, his philosophy of Judaism and religious socialism - it focuses on the two crucial issues of his mature thought: his dialogic or I-Thou philosophy, (...) and his probing of the nature and redemption of evil. As a sensitive, intuitive and perennially fascinating account of one of the twentieth century's great spiritual teachers, and as an influential classic in its own right, Martin Buber: The Life of Dialogue reveals the implications of Buber's thought for theory of knowledge, education, philosophy, myth, history and Judaic and Christian belief. This fully revised and expanded 4th edition includes a new preface from the author, an expanded bibliography incorporating new Buber scholarship, and two new appendices in the form of essays on Buber's influence on Emmanuel Levinas and Mikhail Bakhtin.

Ethical extensionism is a common argument pattern in environmental and animal ethics, which takes a morally valuable trait already recognized in us and argues that we should recognize that value in other entities such as nonhuman animals. I exposit ethical extensionism’s core argument, argue for its validity and soundness, and trace its history to 18th century progressivist calls to expand the moral community and legal franchise. However, ethical extensionism has its critics. The bulk of the paper responds to recent criticisms, (...) including (1) environmental ethicists’ objection against its austere conception of moral value (2), feminist ethicists’ claim that extensionism fails to account for the moral significance of difference, (3) disability theorists’ concern that ethical extensionist arguments are offensive, and (4) animal rights theorists’ lament that extensionism is a practical failure. While something is to be gained from each criticism, I argue that they ultimately fail and that extensionism remains compelling. (shrink)

An introduction to the philosophy of mathematics grounded in mathematics and motivated by mathematical inquiry and practice. In this book, Joel David Hamkins offers an introduction to the philosophy of mathematics that is grounded in mathematics and motivated by mathematical inquiry and practice. He treats philosophical issues as they arise organically in mathematics, discussing such topics as platonism, realism, logicism, structuralism, formalism, infinity, and intuitionism in mathematical contexts. He organizes the book by mathematical themes--numbers, rigor, geometry, proof, computability, incompleteness, (...) and set theory--that give rise again and again to philosophical considerations.

Liberalism sanctifies the values chosen by the sovereign individual. This tends to rule out criticisms of an individual's “preference” for one value over another by, ironically, establishing a deterministic view of the self that protects the self's desires from scrutiny. Similarly, rational choice approaches to social theory begin with previously determined individual preferences and focus on the means by which they are pursued, concentrating on the results rather than the sources of people's values.A striking new attempt to go behind the (...) liberal and rational‐choice starting point in order to understand political preferences is found in Aaron Wildavsky's Cultural Theory. Yet Cultural Theory does not facilitate the criticism of preferences, because its understanding of them is fundamentally liberal. Even while rejecting methodological individualism, Cultural Theory's monocausally social theory of preference formation retains in a new guise the liberal preservation of preferences from criticism by reestablishing a deterministic view of the formation of values, leading it to share with liberalism an a historical view of their origins.

The postwar welfare state provides social insurance against economic, health, and related risks in an uncertain world. Because everyone can envision themselves to be among the unfortunate, social insurance fuses self-interest and solidarism in a normative principle Friedman (2020) calls probabilistic justice. But there is a competing principle of status defense, where the aim is to erect boundaries between socioeconomic strata and discourage cross-class mobility. We argue that this principle dominates when inequality is high and uncertainty low. The current (...) moment is one of high inequality and high uncertainty, which results in intense status anxiety, yet does not rule out solidaristic solutions. Our contributions are to diagnose the causes of our current malaise, and to theorize the normative bases for the political choice facing contemporary western democracies. (shrink)

Drawing upon the life and work of S. Kay Toombs, I explore the impact and import of phenomenological accounts of disability for the existentialist tradition. Through the case of multiple sclerosis, a noncongenital, late-onset, and degenerative disability, I show how the general structures that emerge from its lived experience largely support a mere-difference view of disability and highlight the need for an equitably habitable world. I further argue that phenomenological accounts of disability demonstrate accessibility to be the defining feature of (...) what it means to be embodied as we are. I conclude with a discussion of the more general philosophical relationship between disability, embodiment, and existentialism. (shrink)

This paper pursues two main aims. First, it distinguishes two kinds of improvisation: expert and inexpert. Expert improvisation is a (usually artistic) practice that the agent consciously sets as their goal and is evaluated according to (usually artistic) standards of improvisation. Inexpert improvisation, by contrast, supports and structures the agent’s action as it moves them towards their (usually everyday life) goals and is evaluated on its success leading the agent to the achievement of those goals. The second aim is to (...) describe inexpert improvisation as a robustly distributed affair, one that involves the ongoing integration of embodied practices with social and material resources within our surrounding environments. On the wide approach to improvisation fostered in this paper, inexpert improvisation is claimed to be our default way of inhabiting our world. (shrink)

I develop Tetsurō Watsuji’s relational model of the self as “betweenness”. I argue that Watsuji’s view receives support from two case studies: solitary confinement and dementia. Both clarify the constitutive interdependence between the self and the social and material contexts of “betweenness” that define its lifeworld. They do so by providing powerful examples of what happens when the support and regulative grounding of this lifeworld is restricted or taken away. I argue further that Watsuji’s view helps see the other side (...) of this deprivation, how reconstructing aspects of betweenness is, at the same time, a reconstruction of the self. I conclude by briefly indicating further consequences of this view. (shrink)

The comparison made by Ada Lovelace in 1843 between the Analytical Engine and the Jacquard loom is one of the well-known analogies between looms and computation machines. Given the fact that weaving – and textile production in general – is one of the oldest cultural techniques in human history, the question arises whether this was the first time that such a parallel was drawn. As this paper will show, centuries before Lovelace’s analogy, such a comparison was made by Gottfried Wilhelm (...) Leibniz. During the 17th century, Leibniz compared his calculating machines with another textile machine, the stocking frame, a machine which mechanized knitting and which was invented in 1589. During the following centuries, this machine was considered as a technological wonder and as a creation of God, and, during the last decades of the 17th century, Leibniz emphasized the need to consider it and other textile machines mathematically. What, then, were the reasons for the parallel drawn between this machine and Leibniz’s automatic computation machines? And what were the consequences of this analogy concerning the artisanal knowledge embedded in manual textile practices? (shrink)

Since the publication of Wahrheit und Methode in 1960 (Tfibingen), Gadamer's hermeneutics has called forth a varied and fruitful response from the Continent, without receiving anything near the same attention from the English-speaking world. Though E. D. Hirsch thought Gadamer sufficiently important in 1965 to merit an early rebuttal and rehabilitation (Validity in Interpretation [New Haven, Conn., 1967], pp. 245-64), Wahrheit und Methode remained unread in England and America, partly because a translation was not available until 1975 (Truth and Method, (...) ed. Garrett Barden and John Cumming [New York]). Even after that date, Gadamer's influence on Anglo-American debate has been largely secondhand, filtering in through such figures as Paul Ricoeur and Jiurgen Habermas. But a renewed interest in the question of what we are to make of tradition, no doubt spurred in large measure by deconstruction's effort to unmake it, has lent Gadamer a new pertinence. One sign that his stock is on the rise is the publication of Joel Weinsheimer's Gadamer's Hermeneutics, a much needed and admirably written introduction to Truth and Method that should push its value even higher. -- JSTOR (June 12, 2012.).

Biocentrism, a prominent view in environmental ethics, is the notion that all and only individual biological organisms have moral status, which is to say that their good ought to be considered for its own sake by moral agents. I argue that biocentrism suffers two serious problems: the Origin Problem and the Normativity Problem. Biocentrism seeks to avoid the absurdity that artifacts have moral status on the basis that organisms have naturalistic origins whereas artifacts do not. The Origin Problem contends that, (...) contra biocentrism, an entity’s origin is not relevant to whether that entity has moral status. The Normativity Problem is that biocentrists are preoccupied with accounting for the goods or interests of nonsentient organisms yet fail to establish why interests so construed confer moral status; biocentrism fails to bridge the good-ought gap. It is shown how these problems emerge in three prominent book-length works representative of the biocentrists’ positions over three decades: Paul Taylor’s Respect for Nature, Gary Varner’s In Nature’s Interests?, and Nicholas Agar’s Life’s Intrinsic Value. At minimum, these criticisms suggest that biocentrism is crucially incomplete as a moral framework at present and, optimistically, where more work remains to be done. If biocentrism really is dead, then moral status should be restricted to a more plausible locus such as sentience or rationality, the value of organisms needs a different expression, and environmental ethics needs an axiological foundation different than bare life.
