On the classical account of evolution by natural selection found in Lewontin and many subsequent authors, ENS is conceived as involving three key ingredients: phenotypic variation, fitness differences, and heredity. Through the analysis of three problem cases involving heredity, I argue that the classical conception is substantially flawed, showing that heredity is not required for selection. I consider further problems with the classical account of ENS arising from conflations between three distinct senses of the central concept of ‘fitness’ and offer (...) an alternative to the classical conception of ENS involving the interaction of distinct evolutionary mechanisms.

Multi-level selection can be understood via the Price equation or contextual analysis, which offer incompatible statistical decompositions of evolutionary change into components of group and individual selection. Okasha argued that each approach suffers from problem cases. I introduce further problem cases for the Price approach, arguing that it is appropriate for MLS 2 group selection but not MLS 1. I also show that the problem cases Okasha raises for contextual analysis can be resolved. For some such cases, however, it emerges (...) that there is no determinate answer to the question of how much of the total selective effect was due to group selection compared to individual selection. This suggests that when there is interaction between the effect of group character and individual character, one cannot separate selection into distinct ‘levels’ at all. (shrink)

The Hardy–Weinberg equilibrium has been argued by Sober, Stephens and others to represent the zero-force state for evolutionary biology understood as a theory of forces. I investigate what it means for a model to involve forces, developing an explicit account by defining what the zero-force state is in a general theoretical context. I use this account to show that Hardy–Weinberg equilibrium is not the zero-force state in biology even in the contexts in which it applies, and argue based on this (...) that drift should not be understood as an evolutionary force.

Evolution by natural selection explains the tree of life and the complex adaptations found throughout nature. The power and versatility of evolutionary explanations have proved tempting to scientists outside of biology, but adapting evolutionary concepts to new domains has been challenging. Even within biology, there are many difficult questions and problem cases that face evolutionary theory. Modelling Evolution offers a new, general account of evolution by natural selection that identifies the essential features of evolutionary models that transcend any particular discipline. (...) Evolution by natural selection in its broad sense is the systemic advantage of a type, in contrast to the narrow definition using heritable variation in fitness. This account is explained, contextualised and applied to a variety of questions in both biology and the social sciences. Offering an accessible and comprehensive account of evolution that is applicable both to biology and the broader social sciences, Modelling Evolution will appeal to students and researchers interested in fields such as biology, economics, sociology, history, and psychology.

Nelson and Winter’s An Evolutionary Theory of Economic Change (1982) was the foundational work of what has become the thriving sub-discipline of evolutionary economics. In attempting to develop an alternative to neoclassical economics, the authors looked to borrow basic ideas from biology, in particular a concept of economic “natural selection.” However, the evolutionary models they construct in their seminal work are in many respects quite different from the models of evolutionary biology. There is no reproduction in any usual sense, “mutation” (...) is directed as opposed to blind, and there is no meaningful distinction between phenotype and genotype. Despite these substantial departures from the conceptions of evolutionary biology, I argue that the “evolutionary” economics of Nelson and Winter is indeed a legitimate extension of Darwinian evolutionary principles to a novel domain, and that the traditional conception of evolution by natural selection must be revised. The novel features of evolutionary economics models reflect the distinctive theoretical requirements faced by economists. I further contend that reproduction, heredity, blind variation, and the genotype/phenotype distinction are all inessential to evolutionary theory, and that their role in evolutionary biology is a domain-specific feature of biological theory.

Future-bias is the preference, all else being equal, for positive states of affairs to be located in the future not the past, and for negative states of affairs to be located in the past not the future. Three explanations for future-bias have been posited: the temporal metaphysics explanation, the practical irrelevance explanation, and the three mechanisms explanation. Understanding what explains future-bias is important not only for better understanding the phenomenon itself, but also because many philosophers think that which explanation is (...) the correct one has implications for our evaluation of the normative status of future-bias. In this paper we focus on the connection between future-bias and the temporal value asymmetry. The latter refers to the fact that people tend to assign more value to a state of affairs when it is located in the future, as opposed to being equidistant in the past. All three candidate explanations offered for future-bias proceed by explaining the temporal value asymmetry, and then supposing that future-bias is simply a manifestation of that asymmetry. Recently, however, it has been argued that the conditions under which people display the temporal value asymmetry and future-bias are different, and that this is reason to doubt that the latter is a manifestation of the former. In this paper we empirically test one response to this argument against the manifestation thesis—the simulation response—according to which once we control for the degree to which people can simulate the object of their preference, we find that people display future-bias and the temporal value asymmetry in the same conditions. We find no evidence in favour of the simulation response. Moreover, our results support some previous research that suggests that the temporal value asymmetry is less robust than previously thought, and this in itself casts doubt on the idea that future bias is just a manifestation of this asymmetry.

I argue that influential recent discussions have whitewashed blame, characterizing it in ways that deemphasize or ignore its morally problematic features. I distinguish “definitional,” “creeping,” and “emphasis” whitewash, and argue that they play a central role in overall endorsements of blame by T.M. Scanlon, George Sher, and Miranda Fricker. In particular, these endorsements treat blame as appropriate by definition (Scanlon), or as little more than a wish (Sher), and infer from blame's having one useful function that it is a good (...) practice overall (Fricker). I use an analogy with revenge to illustrate the mechanisms of whitewashing, including broadening a concept to include available alternatives to it and inference from one feature of a practice to an overall conclusion about that practice. Several features of blame make it particularly prone to whitewashing, including blamers' personal or emotional stake in blaming and widespread disagreement about the nature of blame. I argue that a non‐whitewashing treatment of blame must pay closer attention both to blame's harms, and to comparisons between blame and alternative, non‐blaming reactions. (shrink)

In Everettian quantum mechanics, justifications for the Born rule appeal to self-locating uncertainty or decision theory. Such justifications have focused exclusively on a pure-state Everettian multiverse, represented by a wave function. Recent works in quantum foundations suggest that it is viable to consider a mixed-state Everettian multiverse, represented by a (mixed-state) density matrix. Here, we develop the conceptual foundations for decoherence and branching in a mixed-state multiverse, and extend arguments for the Born rule to this setting. This extended framework provides (...) a unification of 'classical' and 'quantum' probabilities, and additional theoretical benefits, for the Everettian picture. (shrink)

Linguistics. Artificial intelligence. Related fields. Computation.

Most Artificial Intelligence theories of language either assume a syntactic component which serves as “front end” for the rest of the system, or else reject all attempts at distinguishing modules within the comprehension system. In this paper we will present an alternative which, while keeping modularity, will account for several puzzles for typical “syntax first” theories. The major addition to this theory is a “marker passing” (or “spreading activation”) component, which operates in parallel to the normal syntactic component.

Taking the formal analogies between black holes and classical thermodynamics seriously seems to first require that classical thermodynamics applies in relativistic regimes. Yet, by scrutinizing how classical temperature is extended into special relativity, I argue that the concept falls apart. I examine four consilient procedures for establishing the classical temperature: the Carnot process, the thermometer, kinetic theory, and black-body radiation. I argue that their relativistic counterparts demonstrate no such consilience in defining the relativistic temperature. As such, classical temperature doesn’t appear (...) to survive a relativistic extension. I suggest two interpretations for this situation: eliminativism akin to simultaneity, or pluralism akin to rotation. (shrink)

Buridan’s Ass faced a choice between two identical bales of hay; governed only by reason, the donkey starved, unable to choose. It seems clear that we face many such cases, and resolve them successfully. Our success seems to tell against any view on which action and intention require evaluative preference. I argue that these views can account for intention and intentional action in cases like that of Buridan’s Ass. A decision to act nonintentionally allows us to resolve these cases without (...) their being a damaging theoretical counterexample. (shrink)

G.E. Moore noticed the oddity of statements like: “It's raining, but I don't believe it.” This oddity is often seen as analogous to the oddity of believing akratically, or believing what one believes one should not believe, and has been appealed to in denying the possibility of akratic belief. I describe a Belief Akratic's Paradox, analogous to Moore's paradox and centered on sentences such as: “I believe it's raining, but I shouldn't believe it.” I then defend the possibility of akratic (...) belief against appeals to this analogy, arguing both that akratic belief does not require belief-akratic-paradoxical belief, and that the latter is importantly different from Moorean belief. I conclude by considering the implications of these arguments for an understanding of both Moorean and akratic belief. (shrink)

At the turn of the twentieth century, William James was America's most widely read philosopher. In addition to being one of the founders of pragmatism, however, he was also a leading psychologist and author of the seminal work, The Principles of Psychology. While scholars argue that James withdrew from the study of psychology after 1890, Eugene Taylor demonstrates convincingly that James remained preeminently a psychologist until his death in 1910.Taylor details James's contributions to experimental psychopathology, psychical research, and the (...) psychology of religion. Moreover, Taylor's work shows that out of his scientific study of consciousness, James formulated a sophisticated metaphysics of radical empiricism. In light of historical developments in psychology, as well as the current philosophic implications of the neuroscience revolution related to the biology of consciousness, Taylor argues that both the subject matter of James's investigations and his metaphysics of radical empiricism are just as important for psychology today as James believed they were in his own time.This book represents a major new contribution both to James scholarship and to the history of American psychology. Although philosophers have analyzed radical empiricism, this book is the first to trace the development of radical empiricism as a metaphysics addressed to psychologists. It is also the first to show James's involvement in depth-psychology and psychotherapeutics and to trace historical continuity between James's work on consciousness and subsequent developments in psychoanalysis, personality theory, and humanistic psychology.

The calibration solution to the stability of the world despite eye movements depends, according to Bridgeman et al., upon a combination of three factors which presumably all need to operate to achieve the goal of stability. Although the authors admit (sect. 4.3, para. 5) that the relative contributions of retinal and extraretinal factors will depend on the particular viewing situation, Figure 5 (sect. 4.3) makes it clear in its representation that the role of perceptual factors is relatively minor compared to (...) extraretinal ones. It is with this representation that this commentary wishes to take issue, believing that it occurs as a result of some assumptions about terminology that may be ambiguous, as well as some misconceptions about the circumstances in which there is a need for stability.

A number of philosophers claim that realism about dark matter in cosmology is unwarranted because there has been no empirical confirmation of a dark matter particle. This demand is misguided. I argue that we should take the theoretical concept of dark matter as described in our best cosmological model (ΛCDM) at face value. Since there is no theoretical or nomological requirement that dark matter be a particle, we should better assess the implications of dark matter detection via gravitational lensing. The (...) result is that realism about dark matter is a viable position. (shrink)

This study investigated students’ perceptions of ethical organizational climates, attitudes towards ethical issues, and the perceived relationship between ethical behavior and success in business organizations. Comparisons were made between the attitudes of these future managers with previously published studies of Russian managers’ attitudes. A survey of 100 business students in three Moscow universities showed that their attitudes toward ethical behavior were more negative than those of Russian managers. No significant differences were found in the perceptions or attitudes of students who (...) had attended an ethics course and those that did not. The implications for both managers and researchers were reported. (shrink)

The present discussion arose from the desire to explain, to an audience of non-physicists, the epistemology to which one is forced if one pursues the quantum mechanical theory of observation to its ultimate consequences. However, the conclusions will not be derived from the aforementioned theory but obtained on the basis of a rather general analysis of what we mean by real. Quantum theory will form the background but not the basis for the analysis. The concept of the real to be (...) arrived at shows considerable similarity to that of the idealist. As the title indicates, it is formulated as a dualism. It is quite possible that it will soon be rejected not only by the community of the philosophers but also by that of the scientists. If this should be the case, the attempt to derive an epistemology from physics will prove to have been premature. Naturally, the author hopes that this will not be the case because, quite apart from the quantum theoretical background, the concepts to be presented appear natural also as an outgrowth of common sense considerations. They have been arrived at by many who did not accept the epistemology of quantum mechanics. (shrink)

_Nomad Citizenship_ argues for transforming our institutions and practices of citizenship and markets in order to release society from dependence on the state and capital. It changes Deleuze and Guattari’s concept of nomadology into a utopian project with immediate practical implications, developing ideas of a nonlinear Marxism and of the slow-motion general strike. Responding to the challenge of creating philosophical concepts with concrete applications, Eugene W. Holland looks outside the state to analyze contemporary political and economic development using the (...) ideas of nomad citizenship and free-market communism. Holland’s nomadology seeks to displace capital-controlled free markets with truly free markets. Its goal is to rescue market exchange, not perpetuate capitalism—to enable noncapitalist markets to coordinate socialized production on a global scale and, with an eye to the common good, to liberate them from capitalist control. In suggesting the slow-motion general strike, Holland aims to transform citizenship: to renew, enrich, and invigorate it by supplanting the monopoly of state citizenship with plural nomad citizenships. In the process, he offers critiques of both the Clinton and Bush regimes in the broader context of critiques of the social contract, the labor contract, and the form of the state itself. (shrink)

The seventeenth and eighteenth centuries are arguably the most important period in philosophy’s history, given that they set a new and broad foundation for subsequent philosophical thought. Over the last decade, however, discontent among instructors has grown with coursebooks’ unwavering focus on the era’s seven most well-known philosophers—all of them white and male—and on their exclusively metaphysical and epistemological concerns. While few dispute the centrality of these figures and the questions they raised, the modern era also included essential contributions from (...) women—like Margaret Cavendish, Elisabeth of Bohemia, Mary Wollstonecraft, and Émilie Du Châtelet—as well as important non-white thinkers, such as Anton Wilhelm Amo, Julien Raimond, and Ottobah Cugoano. At the same time, there has been increasing recognition that moral and political philosophy, philosophy of the natural world, and philosophy of race—also vibrant areas of the seventeenth and eighteenth centuries—need to be better integrated with the standard coverage of metaphysics and epistemology. -/- A New Modern Philosophy: The Inclusive Anthology of Primary Sources addresses—in one volume—these valid criticisms. Weaving together multiple voices and all of the era’s vibrant areas of debate, this volume sets a new agenda for studying modern philosophy. It includes a wide range of readings from 34 thinkers, integrating essential works from all of the canonical writers along with the previously neglected philosophers. Arranged chronologically, editors Eugene Marshall and Susanne Sreedhar provide an introduction for each author that sets the thinker in his or her time period as well as in the longer debates to which the thinker contributed. Study questions and suggestions for further reading conclude each chapter. At the end of the volume, in addition to a comprehensive subject index, the book includes 13 Syllabus Modules, which will help instructors use the book to easily set up different topically structured courses, such as "The Citizen and the State," "Mind and Matter," "Education," "Theories of Perception," or "Metaphysics of Causation." -/- And an eresource offers a wide range of supplemental online resources, including essay assignments, exams, quizzes, student handouts, reading questions, and scholarly articles on teaching the history of philosophy.

FOUNDATIONALISM IN PHILOSOPHY n his autobiographical work, The Education of Henry Adams, this I brooding and disillusioned offspring of American presidents confronted, at age sixty, his own perplexity concerning the new scientific world-view that was emerging at the end of the century. He noted that the unity of things, long guaranteed morally by the teachings of Christianity and scientifically by the Newtonian world-view, was being challenged by a newer vision of things that found only incomprehensible multiplicity at the root of (...) the world: What happened if one dropped the sounder into the ab yss-let it go-frankly gave up Unity altogether? What was Unity? Why was one to be forced to affirm it? Here every body flatly refused help.... [Adams] got out his Descartes again; dipped into his Hume and Berkeley; wrestled anew with his Kant; pondered solemnly over his Hegel and Scho penhauer and Hartmann; strayed gaily away with his Greeks-all merely to ask what Unity meant, and what happened when one denied it. Apparently one never denied it. Every philosopher, whether sane or insane, naturally af firmed it. I Adams, then approaching with heavy pessimism a new century, felt instinc tively that, were one to attack the notion of unity, the entire edifice of human knowledge would quickly collapse. For understanding requires the unification of apparently different phenomena. (shrink)

Sildenafil citrate (Viagra) and other newly released pharmaceuticals that assist erectile dysfunction may be one of the most important categories of drugs released in the past decade. Sildenafil is distinctive because it creates a new therapeutic relationship not only between patient and physician, but also with sexual partner(s). Physicians must first evaluate the patient comprehensively, addressing not only erectile function and sexual performance, but overall physical and mental health. Since the drug does impact others, an expanded model for informed consent (...) needs to be considered. Three models to consider include the public health one, ethically justified limits on confidentiality, and a biopsychosocial one. The biopsychosocial model may be preferred because it expands the patient-physician dyad to directly include others. Physicians also need to distinguish between professional, role-related obligations and personal conscience when treating patients whose sexual beliefs and practices differ from their own. Other ethical issues include inappropriate prescribing over the Internet, dealing with unrealistic patient expectations, and fairness in paying for treatment for sexual conditions in both men and women. With these proposed guidelines, physicians can continue to provide steady, reliable guidance for patients while working with yet another scientific advance in medicine. (shrink)
