Recreative Minds develops a philosophical theory of imagination that draws upon the latest work in psychology. This theory illuminates the use of imagination in coming to terms with art, its role in enabling us to live as social beings, and the psychological consequences of disordered imagination. The authors offer a lucid exploration of a fascinating subject.

What can we learn from fiction? I argue that we can learn about the consequences of a certain course of action by projecting ourselves, in imagination, into the situation of the fiction's characters.

Presenting the first book-length study in English of Aristotle's Sophistical Refutations, this work takes a fresh look at this seminal text on false reasoning.

The book explores the theological understanding of the human person. It does so by placing the theology of person in Karl Rahner's writings in dialogue with the philosophy of the relational person in the works of John Macmurray. It is through the method of dialogue that new insights into the theology of person arise.

The addition of "actually" operators to modal languages allows us to capture important inferential behaviours which cannot be adequately captured in logics formulated in simpler languages. Previous work on modal logics containing "actually" operators has concentrated entirely upon extensions of KT5 and has employed a particular modeltheoretic treatment of them. This paper proves completeness and decidability results for a range of normal and nonnormal but quasi-normal propositional modal logics containing "actually" operators, the weakest of which are conservative extensions of K, (...) using a novel generalisation of the standard semantics.

Only one traditional objection to Pascal's wager is telling: Pascal assumes a particular theology, but without justification. We produce two new objections that go deeper. We show that even if Pascal's theology is assumed to be probable, Pascal's argument does not go through. In addition, we describe a wager that Pascal never considered, which leads away from Pascal's conclusion. We then consider the impact of these considerations on other prudential arguments concerning what one should believe, and on the more general (...) question of when and why belief formation ought to be based solely on the evidence.

Kripkean examples of necessary a posteriori truths clearly provide a challenge to attempts to connect facts about possibility to facts about what people can conceive. The paper argues for a general principle connecting imaginability under certain special circumstances to possibility; it also discusses some of the issues raised by the resulting position.

The article presents the issues arising from the memberships of moral agents in collectives that have the burden of moral responsibility. Likewise, it examines the qualifying actions that qualify their membership including deliberate contribution, risk taking and others. It differentiates collective responsibility to shared responsibility.

OPINION IS DIVIDED as to whether the "qualitative characters" or "qualia" of conscious sensory experiences such as color perceptions and pain sensations genuinely constitute a major obstacle to the success or tenability of contemporary physicalist theories of mind. Do the enormous complexities of human brain activity--conceived more or less as we now conceive it--alone suffice to account for our conscious sensory experiences, and thereby show how the experiences are nothing over and above the brain activities, or must there be some (...) further kind of thing, if we are to account for the existence of our kind of consciousness? This issue, representing perhaps the most profound division of opinion in contemporary philosophy of mind, cannot possibly reach a genuine resolution in the absence of a satisfactory answer to a question which has suffered astonishing neglect in the extensive debate on this issue: What exactly is the qualitative character of a conscious sensory experience? What exactly is it about color perception, for example, that makes it so distinctive in a "qualitative" respect, allegedly making trouble for contemporary theories of mind? (shrink)

Hilbert’s unpublished 1917 lectures on logic, analyzed here, are the beginning of modern metalogic. In them he proved the consistency and Post-completeness (maximal consistency) of propositional logic -results traditionally credited to Bernays (1918) and Post (1921). These lectures contain the first formal treatment of first-order logic and form the core of Hilbert’s famous 1928 book with Ackermann. What Bernays, influenced by those lectures, did in 1918 was to change the emphasis from the consistency and Post-completeness of a logic to its (...) soundness and completeness: a sentence is provable if and only if valid. By 1917, strongly influenced by PM, Hilbert accepted the theory of types and logicism -a surprising shift. But by 1922 he abandoned the axiom of reducibility and then drew back from logicism, returning to his 1905 approach of trying to prove the consistency of number theory syntactically. (shrink)

The purpose of this paper is to show that if one adopts conditional probabilities as the primitive concept of probability, one must deal with the fact that even in very ordinary circumstances at least some probability values may be imprecise, and that some probability questions may fail to have numerically precise answers.

From 1953 to 1959 Gödel worked on a response to Carnap’s philosophy of mathematics. The drafts display Gödel’s familiarity with Carnap’s position from The Logical Syntax of Language, but they received a dismissive reaction on their eventual, posthumous, publication. Gödel’s two principal points, however, will here be defended. Gödel, though, had wished simply to append a few paragraphs to show that the same arguments apply to Carnap’s later views. Carnap’s position, however, had changed significantly in the intervening years, and to (...) a significant extent, this mature position realizes much of what Gödel himself wanted out of a philosophy of mathematics.

The balance of nature concept is an old idea that manifests itself in anumber of forms in population and community ecology. This paper focuseson population ecology, where controversy surrounding the balance ofnature takes the form of perennial debates over the significance ofdensity dependence, population regulation, and species interactions suchas competition. One of the most striking features of these debates, overthe course of the previous century in ecology, is the tendency to arguethe case on largely conceptual grounds. This paper explores twoquestions. (...) Why this tendency to settle on conceptual grounds what is soobviously an empirical issue? Are there any good conceptual arguments tobe had in this area?

In On the Origin of Species, Charles Darwin put forward his theory of natural selection. Conventionally, Darwin's argument for this theory has been understood as based on an analogy with artificial selection. But there has been no consensus on how, exactly, this analogical argument is supposed to work – and some suspicion too that analogical arguments on the whole are embarrassingly weak. Drawing on new insights into the history of analogical argumentation from the ancient Greeks onward, as well as on (...) in-depth studies of Darwin's public and private writings, this book offers an original perspective on Darwin's argument, restoring to view the intellectual traditions which Darwin took for granted in arguing as he did. From this perspective come new appreciations not only of Darwin's argument but of the metaphors based on it, the range of wider traditions the argument touched upon, and its legacies for science after the Origin.

College of Medicine, University of South Alabama Mobile, AL 36688-0002, USA wbp501{at}jaguar1.usouthal.edu ' + u + '@' + d + ' '//--> Abstract Recent work in viral genomics has shown that bacteriophages exhibit a high degree of mosaicism, which is most likely due to a long history of prolific horizontal gene transfer (HGT). Given these findings, we argue that each of the most plausible attempts to properly classify bacteriophages into distinct species fail. Mayr's biological species concept fails because there is (...) no useful viral analog to sexual reproduction. Phenetic species concepts fail because they obscure the mosaicism and the rich reticulated viral histories. Phylogenetic species concepts, even when extended to take into account reticulation, fail because there is no non-arbitrary distinction between recombination events that create a new viral species and those that do not. There is good reason to think that bacteriophages, arguably the Earth's most abundant biological agent, evolve without forming species.

Five experiments investigated how people use categories to make inductions about objects whose categorisation is uncertain. Normatively, they should consider all the categories the object might be in and use a weighted combination of information from all the categories: bet-hedging. The experiments presented people with simple, artificial categories and asked them to make an induction about a new object that was most likely in one category but possibly in another. The results showed that the majority of people focused on the (...) most likely category in making inductions, although there was a group of consistently normative responders who used information from both categories (about 25% of our college population). Across experiments the overall pattern of results suggests that performance in the task is improved not by understanding the underlying principles of bet-hedging but by increasing the likelihood that multiple categories are in working memory at the time of the induction. We discuss implications for improving everyday inductions. (shrink)

the saap 2020 conference in mexico is the culmination of an internal and gradual transformation in SAAP that has taken many years. I came to this organization as a graduate student. I was then the only Latino and Leonard Harris the only African American philosopher in SAAP.

In his new introduction to the 1925 second edition of Principia Mathematica, Russell maintained that by adopting Wittgenstein's idea that a logically perfect language should be extensional mathematical induction could be rectified for finite cardinals without the axiom of reducibility. In an Appendix B, Russell set forth a proof. Godel caught a defect in the proof at *89.16, so that the matter of rectification remained open. Myhill later arrived at a negative result: Principia with extensionality principles and without reducibility cannot (...) recover mathematical induction. The finite cardinals are indefinable in it. This paper shows that while Gödel and Myhill are correct, Russell was not wrong. The 1925 system employs a different grammar than the original Principia. A new proof for *89.16 is given and induction is recovered. (shrink)

It was commonly accepted in Goethe’s time that plants were equipped both to propagate themselves and to play a certain role in the natural economy as a result of God’s beneficent and providential design. Goethe’s identification of sexual propagation as the “summit of nature” in The Metamorphosis of Plants (1790) might suggest that he, too, drew strongly from this theological-metaphysical tradition that had given rise to Christian Wolff’s science of teleology. Goethe, however, portrayed nature as inherently active and propagative, itself (...) improvising into the future by multiple means, with no extrinsically pre-ordained goal or fixed end-point. Rooted in the nature philosophy of his friend and mentor Herder, Goethe’s plants exhibit their own historically and environmentally conditioned drives and directionality in The Metamorphosis of Plants. In this paper I argue that conceiving of nature as active productivity—not merely a passive product—freed Goethe of the need to tie plants’ forms and functions to a divine system of ends, and allowed him to consider possibilities for plants, and for nature, beyond the walls of teleology.

Since the late 1960s, philosophy for children has become a global, multi-disciplinary movement involving innovations in curriculum, pedagogy, educational theory, and teacher education; in moral, social and political philosophy; and in discourse and literary theory. And it has generated the new academic field of philosophy of childhood. Gareth B. Matthews (1929-2011) traced contemporary disrespect for children to Aristotle, for whom the child is essentially a pre-intellectual and pre-moral precursor to the fully realized human adult. Matthews Matthews dubbed this the “deficit (...) conception of childhood” and wrote extensive critiques of its perpetuation in Jean Piaget’s stage model of cognitive development and in Lawrence Kholberg’s stage model of moral development. He published the first book (1994) in the field of philosophy of childhood and wrote a column of reviews of philosophically-oriented children’s books. He argued that even academic philosophers can benefit from the freshness and directness of children’s thinking. For Matthew Lipman (1923-2010) and Ann Margaret Sharp (1942-2010), the child is only potentially a philosophical agent and grows into becoming such by means of a philosophical education. Lipman invented the literary genre of children’s philosophical fiction, which systematically reconstructs key philosophical issues and positions in language accessible by children, attempts to help children recognize philosophical dimensions of their own experience, and models philosophical dialogue. Lipman and Sharp developed a protocol for a “community of philosophical inquiry,” in which people with diverse experiences, ideas and concerns dialogue together around a shared philosophical question, with the aim of forming reasonable, meaningful judgments about the matter. The early success of philosophy for children was due in part to its coincidence with the critical thinking movement in education, in which Lipman was an important figure. Its emphasis on ethics has justified its use as a program of ethics, character, and even religious education. It has also been used for civics education, because of how it instantiates democratic deliberation and power-sharing. At the same time, philosophy for children has been criticized by religious and social conservatives, developmental psychologists, and philosophers. Today, the diversity of approaches, aims, materials, and grounding theories of philosophy for children signifies different understandings of philosophy, childhood and education, which have become “essentially contested concepts” within the movement. Philosophy for children is no longer unified by an identifiable theory, purpose, pedagogy, method or curriculum, but is now used to further a number of disparate educational agendas. Shaun Gallagher’s (1992) heuristic of four schools of hermeneutics is helpful in understanding these competing agendas. Conservative hermeneutics is the attempt to devise methods of interpretation that uncover and preserve truth or original meaning without distortion or bias. This is consonant with the use of philosophy for children to help young people appropriate the fundamental questions, ideas and skills of (Western) philosophy as a resource for understanding the world and managing their own experience, and with the understanding critical thinking as a way of avoiding prejudice and approaching truth. Critical hermeneutics approaches interpretation—including teaching and learning—as a method of liberating the interpreter from the racist, sexist, homophobic, capitalist, religiously fanatical, and other kinds of ideologies that commonly distort thinking, feeling and behavior. This is consonant with those who argue that the attributes of mutual criticism, inclusion, solidarity, self-regulation, and distributed power make the community of philosophical inquiry an ideal site for recognizing and overcoming ideology. Others find philosophy for children politically ineffectual due to the limited role of students and teachers in co-constructing the curriculum and its lack of an explicit component of political critique and action. Radical hermeneutics suggests that because every text is open to a plurality of meanings, the purpose of interpretation is not to artificially constrain that plurality but to play with the signs that constitute the text in order to achieve fresh insights. A radical hermeneutical strand is identifiable in the philosophy for children literature when scholars resist the idea that the aim of philosophical dialogue is to find consensus or to narrow down on the most reasonable conclusions. Moderate hermeneutics holds that the work of interpretation is the attempt to reach meaning or shared understanding in a process modeled on dialogue between the familiar and the strange. This is consonant with those who argue that philosophical traditions can still give meaning to (young) people’s lives, but that those traditions must be continually reinterpreted (including by children) in order to survive and flourish. Fifty-odd years since its inception, philosophy for children has deepened and diversified, both theoretically and as a field of practice. Perhaps the only point of agreement among (most) everyone in the movement is that children’s philosophical thinking, variously understood, is necessary for the realization of the intellectual, moral, and political agency the movement attributes to them.

In this paper, I argue against John Beatty’s position in his paper “The Evolutionary Contingency Thesis” by counterexample. Beatty argues that there are no distinctly biological laws because the outcomes of the evolutionary processes are contingent. I argue that the heart of the Caspar–Klug theory of virus structure—that spherical virus capsids consist of 60T subunits (where T = k 2 + hk + h 2 and h and k are integers)—is a distinctly biological law even if the existence of spherical (...) viruses is evolutionarily contingent.

This article compares the theory of Meinongian objects proposed by Edward Zalta with a theory of fiction formulated within an early Russellian framework. The Russellian framework is the second-order intensional logic proposed by Nino B. Cocchiarelly as a reconstruction of the form of Logicism Russell was examining shortly after writing The Principles of Mathematics. A Russellian theory of denoting concepts is developed in this intensional logic and applied as a theory of the "objects' of fiction. The framework retains the Orthodox (...) early Russellian ontology of existents, possible non-existents, and properties and relations in intension. This avoids the assumption, found in Meinongian theories, of impossible and incomplete objects. It also obviates the need to preserve consistency by distinguishing a new "mode of predication", or a "distinction in kinds of predicates". Thus, it is argued that an early Russellian theory forms a powerful rival to a Meinongian theory of objects. (shrink)

There is a long history of controversy in ecology over the role of competition in determining patterns of distribution and abundance, and over the significance of the mathematical modeling of competitive interactions. This paper examines the controversy. Three kinds of considerations have been involved at one time or another during the history of this debate. There has been dispute about the kinds of regularities ecologists can expect to find, about the significance of evolutionary considerations for ecological inquiry, and about the (...) empirical credentials of theoretical studies of competition. Each of these elements is examined with an eye toward gaining philosophical clarification of the issues involved. In the process, certain shortcomings of contemporary philosophical theories are revealed. In particular, I argue that plausibility arguments based on background considerations are an important part of the model building tradition, but that current accounts of the structure and evaluation of scientific theories do little to illuminate this side of theoretical ecology.
