Wilkins & Wakefield suggest that changes in the hominid brain made it uniquely “preadaptive” for language, yet no precursor functions served as adaptive substrates to the emergence of language. We present contrary evidence that the ability to discriminate and process rapid and complex auditory information is a cross-species function subserving communication processes including, but not limited to, human speech perception. We suggest that auditory temporal processing served as an evolutionary precursor to speech processing and consequent language development in humans.

Historically, studies of the role of endogenous hormones in developmental differentiation of the sexes have suggested that mammalian sexual differentiation is mediated primarily by testicular androgens, and that exposure to androgens in early life leads to a male brain as defined by neuroanatomy and behavior. The female brain has been assumed to develop via a hormonal default mechanism, in the absence of androgen or other hormones. Ovarian hormones have significant effects on the development of a sexually dimorphic cortical structure, the (...) corpus callosum, which is larger in male than in female rats. In the females, removal of the ovaries as late as Day 16 increases the cross-sectional area of the adult corpus callosum. Treatment with low-dose estradiol starting on Day 25 inhibits this effect. Female callosa are also enlarged by a combination of daily postnatal handling and exogenous testosterone administered prior to Day 8. The effects of androgen treatment are expressed early in development, with males and testosterone-treated females having larger callosa than control females as early as Day 30. The effects of ovariectomy do not appear until after Day 55. These findings are more consistent with other evidence of a later sensitive period for ovarian feminization as compared to androgenic masculinization. (shrink)

A number of commentators agree that the evidence reviewed in the target article supports a previously unrecognized role for ovarian hormones in feminization of the brain. Others question this view, suggesting that the traditional model of sexual differentiation already accounts for ovarian influence. This position is supported by various reinterpretations of the data presented (e.g., ovarian effects are secondary to the presence/absence of androgen, ovarian effects are smaller than testicular effects, ovarian effects are not organizational). We discuss these issues, and (...) reiterate our position that evidence of neurobehavioral ovarian effects is incompatible with the currently accepted model of sexual differentiation. Other points regarding species generalizations, the direct versus indirect action of estrogen, and nonhormonal mechanisms of sexual differentiation are also discussed. Finally, we address the controversial issue of using ratio scores in the assessment of the human corpus callosum (where CC scores are divided by an index of brain size). Future applications to human research are also discussed. (shrink)

'Alain Badiou: Between Theology and Anti-theology' provides one of the first comprehensive analyses of the relationship between Badiou's philosophy and theology. Examining the full range of Badiou's writings, this provocative study explores how Badiou's philosophy relies on theology even if he claims otherwise and actively attempts to work against theology. Despite the complex questions discussed - ranging across ontology, the theory of truth and the subject, philosophy and its conditions, and anti-philosophy - this book presents a clear and accessible overview (...) of the theological, religious and biblical themes which animate Badiou's philosophy.

Roslyn Weiss offers a new interpretation of Platonic moral philosophy based on an unconventional reading of the Republic. Her basic argument begins with the point that Plato means for us to react badly to the philosopher-rulers of Book 7. She then makes the case that there are two distinct kinds of philosopher in the Republic--one that is ideal and one that is farcical--and that each represents a separate type of justice. Finally, she argues that Plato recognizes this dualism and (...) points the way toward a resolution"--Publisher's Web site. (shrink)

Economics is probably the most subtle, precise and powerful of the social sciences and its theories have deep philosophical import. Yet the dominant alliance between economics and philosophy has long been cheerfully simple. This is the textbook alliance of neo-Classicism and Positivism, so crucial to the defence of orthodox economics against by now familiar objections. This is an unusual book and a deliberately controversial one. The authors cast doubt on assumptions which neo-Classicists often find too obvious to defend or, indeed, (...) to mention. They set out to disturb an influential concensus and to champion an unpopular cause. Although they go deeper into both philosophy and economics than is usual in interdisciplinary works, they start from first principles and the text is provokingly clear. This will be a stimulating book for all economic theorists and philosophers interested in the philosophy of science and social science. (shrink)

I highlight a metaphysical concern that stands in the way of more widespread adoption of causal modeling techniques such as causal Bayes nets. Researchers in some fields may resist adoption due to concerns that they don't 'really' understand what they are saying about a system when they apply such techniques. Students in these fields are repeated exhorted to be cautious about application of statistical techniques to their data without a clear understanding of the conditions required for those techniques to yield (...) genuine insight into the data. They are acutely aware that anyone can chuck some data into a software package and get what looks like an answer, even though these tests may not be well-defined for the data on which they can apparently be run. This is thus a healthy skepticism for uptake of causal modeling methods, which points directly to the need for a metaphysical understanding of causation in order to successfully use the modeling methods. Without a clear understanding of what the methods are committing to, including what it means to say that there exists a causal relationship, researchers have limited ability to identify potentially bad output, or to independently verify results.

Even in areas of philosophy of science that don’t involve formal treatments of truth, one’s background view of truth still centrally shapes views on other issues. I offer an informal way to think about truth as trueing, like trueing a bicycle wheel. This holist approach to truth provides a way to discuss knowledge products like models in terms of how well-trued they are to their target. Trueing emphasizes: the process by which models are brought into true; how the idealizations in (...) models are not false but rather like spokes in appropriate tension to achieve a better-trued fit to target; and that this process is not accomplished once and done forever, but instead requires upkeep and ongoing fine-tuning. I conclude by emphasizing the social importance of being a pragmatist about truth in order to accurately answer questions about science such as, “but do we really know that…”. (shrink)

Are 'the people' too ignorant or stupid to rule? Commentators are beginning to seriously argue that the answer might be 'yes.' In this take-no-prisoners book, Roslyn Fuller shows how many thinkers have embraced the idea that there can be 'too much democracy,' and deftly unravels their attempts to end majority rule.

Losing an arm to rescue a child from a burning building is supererogatory. But is losing an arm to save two children more supererogatory than losing two arms to save a single child? What factors make one act more supererogatory than another? I provide an innovative account of how to compare which of two acts is more supererogatory, and show the superiority of this account to its chief rival.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 39.1 (2001) 137-139 [Access article in PDF] Gareth B. Matthews. Socratic Perplexity and the Nature of Philosophy. New York: Oxford University Press, 1999. Pp. 137. Cloth, $29.95 Thomas C. Brickhouse and Nicholas D. Smith. The Philosophy of Socrates. Boulder, CO: Westview Press, 2000. Pp. x + 290. Paper $22.00. Matthews' little book tracks the course of Socrates' perplexity, which, Matthews contends, starts out (...) as an obstacle to successful inquiry, but becomes, eventually, itself the target of inquiry. Matthews regards as quite genuine the perplexity that Socrates professes in certain of the early dialogues—Laches, Charmides, Euthyphro—largely, however, because Matthews himself finds Socrates' questions so stubbornly persistent. Yet, couldn't Socrates, at least with respect to some of his questions, experience no state of confusion, no perplexity, but, nevertheless, profess perplexity? Perhaps Socrates' confessions of perplexity signal only his awareness that he lacks knowledge of virtue; perhaps they are but rhetorical devices for encouraging Socrates' interlocutors to admit to their own ignorance.As the book continues, Matthews, following a line fairly standard by now, thinks that, in the "transitional" Meno, Socrates discovers two ways out of the perplexity: recollection, and the method of hypothesis; and that, in the "middle" dialogues—the Republic and Phaedo—the Theory of Forms comes to his rescue. In the Parmenides and, perhaps later, Matthews maintains, the Theory of Forms becomes itself the object of inquiry, as Socrates recognizes the perplexities with which it is fraught. Matthews mentions, but takes no stand on, the controversies surrounding the late dialogues, moving on at last to Aristotle and the different kind of perplexity one encounters there.For the briefest moment it looks as if Matthews might resist the standard line, when, in discussing the Meno, he notices not only that the geometrical problem of the Meno's slave-boy passage causes no perplexity comparable to that caused by Socrates' philosophical problems, but that Socrates is fully in charge in the geometrical demonstration, stinging another without simultaneously stinging himself. Yet, not only does Matthews fail to pursue his insight that moral or philosophical questions are, for Socrates, not like mathematical ones; on the contrary, he suggests that, in the Phaedo, philosophical problems are viewed by Socrates as mathematical ones.In The Philosophy of Socrates, Brickhouse and Smith undertake the ambitious task of expounding and defending a coherent and cohesive Socratic philosophy, one that encompasses Socrates' method, his wisdom and ignorance, his understanding of the nature of knowledge, his moral philosophy, psychology, politics, and religion. For a book meant to be a popular introduction, it is remarkably comprehensive—even [End Page 137] exhaustive—and serves to acquaint the reader with the current scholarly controversies surrounding Socratic philosophy as it is debated in the analytic tradition associated most frequently with the late and great Gregory Vlastos.In many respects, The Philosophy of Socrates is but an updated version of Brickhouse and Smith's earlier book, Plato's Socrates (Oxford University Press, 1994)—though without the rich and copious notes. The earlier book is the better one. The new book, although it purports to discuss the philosophy of the historical Socrates, is, from Chapter 2 on, a book about the Socrates of Plato's "early" dialogues. Yet, it is precisely this Socrates who is largely absent from its pages. The Socrates of the early dialogues is a character: both in the sense that he is a protagonist in the dramas that are Plato's dialogues, and in the sense that he is sarcastic, funny, makes bad puns, strikes at his interlocutors where they are most vulnerable, teases, baits, and annoys. But, most importantly, this Socrates is no solitary thinker. He talks to people; and what he says and how he says it is influenced both by his interlocutor and by the context of their conversation. Brickhouse and Smith, however, take such factors into account but rarely—and then only to save their own take on a particular Socratic doctrine.The two interpretive principles that Brickhouse and Smith invoke most often...

This chapter examines the relationship between laws and mechanisms as approaches to characterising generalizations and explanations in science. I give an overview of recent historical discussions where laws failed to satisfy stringent logical criteria, opening the way for mechanisms to be investigated as a way to explain regularities in nature. This followed by a critical discussion of contemporary debates about the role of laws versus mechanisms in describing versus explaining regularities. I conclude by offering new arguments for two roles for (...) laws that mechanisms cannot subsume, one epistemically optimistic and one pessimistic, both broadly Humean. Do note that this piece is not primarily Hume exegesis; it is more of a riff in the key of Hume. (shrink)

Does it make sense to refer to bird song - a complex vocalization, full of repetitive and transformative patterns that are carefully calculated to woo a mate - as art? What about a pack of wolves howling in unison or the cacophony made by an entire rain forest? Redefining music as "the art of possibly animate things," Musical Vitalities charts a new path for music studies that blends musicological methods with perspectives drawn from the life sciences. In opposition to humanist (...) approaches that insist on a separation between culture and nature--approaches that appear increasingly untenable in an era defined by human-generated climate change--Musical Vitalities treats music as one example of the cultural practices and biotic arts of the animal kingdom rather than as a phenomenon categorically distinct from nonhuman forms of sonic expression. The book challenges the human exceptionalism that has allowed musicologists to overlook music's structural resemblances to the songs of nonhuman species, the intricacies of music's physiological impact on listeners, and the many analogues between music's formal processes and those of the dynamic natural world. Through close readings of Austro-German music and aesthetic writings that suggest wide-ranging analogies between music and nature, Musical Vitalities seeks to both rekindle the critical potential of nineteenth-century music and rejoin the humans at the center of the humanities with the nonhumans whose evolutionary endowments and planetary fates they share.

This chapter examines the philosophical discussion concerning the relationship between time, memory, attention, and consciousness, from Locke through the Scottish Common Sense tradition, in terms of its influence on James' development of the specious present doctrine. The specious present doctrine is the view that the present moment in experience is non punctate, but instead comprises some nonzero amount of time; it contrasts with the mathematical view of the present, in which the divide between past and future is merely a point (...) or a line with no thickness. The anonymous source for the term 'specious present' is revealed as a retired businessman-turned-amateur philosopher. The more likely source for the idea itself is a little-known philosopher, Shadworth Hollway Hodgson, who was not merely a significant influence on James but also on Husserl's development of the tripartite account of internal time consciousness. I conclude by demonstrating how James' changing views on the relationship between concepts and experience meant that by the later period of his writings, including those in which he develops his own views on pragmatism, James would have not merely noted the contrast between a mathematical conception of the present and our actual experience of it, he would have taken a further step and condoned the thick experience of the present as demonstrating the inadequacy of the intellectualized mathematical characterization.

If pragmatism, hitherto, has been content with elaborating theories of meaning and of truth, but has neglected epistemology, there are good reasons for that neglect. For one thing, much of the accepted vocabulary of epistemological discussion begs the questions under discussion. Again, much epistemology is simply an oblique metaphysics, and not an empirical investigation of knowledge, and hence throws no light on knowing as we practice it. But another reason for this neglect lies in the very simplicity of an experimental (...) theory of knowing. Its charms are not enhanced by undulating draperies of dialectic,' nor warded by the numerological incantations of a symbolic logic, nor made elusive by recondite reference to relativity physics. Nevertheless, it is to the exposition of this elementary doctrine that I mean now to proceed. And I shall do so simply, and with seeming dogmatism, by taking the categories of field, focus, and perspective, and working them for all they are worth in an experimental epistemology... (shrink)

This Is A New Release Of The Original 1906 Edition.

Twentieth century philosophers introduced the distinction between “objective rightness” and “subjective rightness” to achieve two primary goals. The first goal is to reduce the paradoxical tension between our judgments of what is best for an agent to do in light of the actual circumstances in which she acts and what is wisest for her to do in light of her mistaken or uncertain beliefs about her circumstances. The second goal is to provide moral guidance to an agent who may be (...) uncertain about the circumstances in which she acts, and hence is unable to use her standard moral principle directly in deciding what to do. This paper distinguishes two important senses of “moral guidance”; proposes criteria of adequacy for accounts of subjective rightness; canvasses existing definitions for “subjective rightness”; finds them all deficient; and proposes a new and more successful account. It argues that each comprehensive moral theory must include multiple principles of subjective rightness to address the epistemic situations of the full range of moral decision-makers, and shows that accounts of subjective rightness formulated in terms of what it would reasonable for the agent to believe cannot provide that guidance.

Recently two distinct forms of rule-utilitarianism have been introduced that differ on how to measure the consequences of rules. Brad Hooker advocates fixed-rate rule-utilitarianism, while Michael Ridge advocates variable-rate rule-utilitarianism. I argue that both of these are inferior to a new proposal, optimum-rate rule-utilitarianism. According to optimum-rate rule-utilitarianism, an ideal code is the code whose optimum acceptance level is no lower than that of any alternative code. I then argue that all three forms of rule-utilitarianism fall prey to two fatal (...) problems that leave us without any viable form of rule-utilitarianism. (shrink)

It's commonly understood within the academy that the terms "man," "woman," and "other" are socially constructed, and that their meanings are maintained by the current political order. But few thinkers have attempted to reconcile that knowledge - which is rooted in Marxism - with queer theory. The few who have, meanwhile, usually attempt to do so through issues of libidinal desire and sexual expression. In the Politics of Everybody, Holly Lewis argues powerfully that the emphasis on desire, though seemingly (...) innocuous, is actually symptomatic of neoliberal habits of thought, and consequently, is responsible for a continued focus on the limited politics of identity. Instead, Lewis shows, we should look to the arena of body production, categorization, and exclusion; only through such a reorientation can we create a politics of liberation that is truly inclusive and grounded in lived experience."-- Provided by publisher.

Metaphors of medicine are common, such as war, which is evident in much of our language about health‐care where patients and healthcare professionals fight disease, or the game, which is one way to frame the nurse–doctor professional relationship. This study analyses six pilot episodes of American (Grey's Anatomy, Hawthorne, Mercy, Nurse Jackie) and Australian (All Saints, RAN) medical television programmes premiering between 1998 and 2009 to assess one way that our contemporary culture understands and constructs professional relationships between nurses and (...) doctors. Analysis shows that these popular television programmes frequently depict conflict, with games, civil war and mutiny between nurses and doctors over patient safety rather than professionals working collaboratively in teams to deliver health‐care. Although the benefit of this televised conflict is the implication that nurses are knowledgeable, skilled professionals, the negative connotations include a dysfunctional and dangerous healthcare system, and also ongoing power struggles. Given that popular culture can sometimes influence the public's understanding of real‐life nursing practice, it is important to explore what these metaphors of conflict are communicating about the nurse–doctor relationship.

Even though the evidence‐based medicine movement (EBM) labels mechanisms a low quality form of evidence, consideration of the mechanisms on which medicine relies, and the distinct roles that mechanisms might play in clinical practice, offers a number of insights into EBM itself. In this paper, I examine the connections between EBM and mechanisms from several angles. I diagnose what went wrong in two examples where mechanistic reasoning failed to generate accurate predictions for how a dysfunctional mechanism would respond to intervention. (...) I then use these examples to explain why we should expect this kind of mechanistic reasoning to fail in systematic ways, by situating these failures in terms of evolved complexity of the causal system(s) in question. I argue that there is still a different role in which mechanisms continue to figure as evidence in EBM: namely, in guiding the application of population‐level recommendations to individual patients. Thus, even though the evidence‐based movement rejects one role in which mechanistic reasoning serves as evidence, there are other evidentiary roles for mechanistic reasoning. This renders plausible the claims of some critics of evidencebased medicine who point to the ineliminable role of clinical experience. Clearly specifying the ways in which mechanisms and mechanistic reasoning can be involved in clinical practice frames the discussion about EBM and clinical experience in more fruitful terms.

In this field guide, I distinguish five separate senses with which the term ‘mechanism’ is used in contemporary philosophy of science. Many of these senses have overlapping areas of application but involve distinct philosophical claims and characterize the target mechanisms in relevantly different ways. This field guide will clarify the key features of each sense and introduce some main debates, distinguishing those that transpire within a given sense from those that are best understood as concerning distinct senses. The ‘new mechanisms’ (...) sense is at the center of most of these contemporary debates and will be treated at greater length; subsequent senses of mechanism will be primarily distinguished from this one. In part I of this paper, I distinguish two senses of the term ‘mechanism’, both of which are explicitly hierarchical and nested in character, such that any given mechanism is comprised of smaller sub-mechanisms, in turn comprised of yet smaller sub-sub-mechanisms and so on. While both of the senses discussed here are anti-reductive, they differ in their focus on scientific practice versus metaphysics, in the degree of regularity they attribute to mechanisms, and in terms of their relationships to the discussions of mechanisms in the history of philosophy and science.

A finer-grained delineation of a given explanandum reveals a nexus of closely related causal and non- causal explanations, complementing one another in ways that yield further explanatory traction on the phenomenon in question. By taking a narrower construal of what counts as a causal explanation, a new class of distinctively mathematical explanations pops into focus; Lange’s characterization of distinctively mathematical explanations can be extended to cover these. This new class of distinctively mathematical explanations is illustrated with the Lotka-Volterra equations. There (...) are at least two distinct ways those equations might hold of a system, one of which yields straightforwardly causal explanations, but the other of which yields explanations that are distinctively mathematical in terms of nomological strength. In the first, one first picks out a system or class of systems, finds that the equations hold in a causal -explanatory way; in the second, one starts with the equations and explanations that must apply to any system of which the equations hold, and only then turns to the world to see of what, if any, systems it does in fact hold. Using this new way in which a model might hold of a system, I highlight four specific avenues by which causal and non- causal explanations can complement one another. (shrink)

This paper articulates an account of causation as a collection of information-theoretic relationships between patterns instantiated in the causal nexus. I draw on Dennett’s account of real patterns to characterize potential causal relata as patterns with specific identification criteria and noise tolerance levels, and actual causal relata as those patterns instantiated at some spatiotemporal location in the rich causal nexus as originally developed by Salmon. I develop a representation framework using phase space to precisely characterize causal relata, including their degree (...) of counterfactual robustness, causal profiles, causal connectivity, and privileged grain size. By doing so, I show how the philosophical notion of causation can be rendered in a format that is amenable for direct application of mathematical techniques from information theory such that the resulting informational measures are causal informational measures. This account provides a metaphysics of causation that supports interventionist semantics and causal modeling and discovery techniques. (shrink)

The requirement that moral theories be usable for making decisions runs afoul of the fact that decision makers often lack sufficient information about their options to derive any accurate prescriptions from the standard theories. Many theorists attempt to solve this problem by adopting subjective moral theories—ones that ground obligations on the agent’s beliefs about the features of her options, rather than on the options’ actual features. I argue that subjective deontological theories suffer a fatal flaw, since they cannot appropriately require (...) agents to gather information before acting. (shrink)

Background In end-of-life situations, the phrase “do everything” is sometimes invoked by physicians, patients, or substitute decision-makers, though its meaning is ambiguous. We examined instances of the phrase “do everything” in the archive of the Ontario Consent and Capacity Board in Canada, a tribunal with judicial authority to adjudicate physician–patient conflicts in order to explore its potential meanings. Methods We systematically searched the CCB’s online public archive from its inception to 2018 for any references to “do everything” in the context (...) of critical care medicine and end-of-life care. Two independent assessors reviewed decisions, collected characteristics, and identified key themes. Results Of 598 cases in the archive, 41 referred to “do everything” in end-of-life situations. The phrase was overwhelmingly invoked by SDMs, typically to advocate for life-prolonging measures that contradicted physician advice. Physicians generally related “doing everything” to describe the interventions they had already performed, using it to recommend focusing on patients’ quality of life. SDMs were generally reluctant to accept death, whereas physicians found prolonging life at all costs to be morally distressing. The CCB did not interpret appeals to “do everything” legally but followed existing laws by deferring to patients’ prior wishes whenever known, or to concepts of “best interests” when not. The CCB generally recommended against life-prolonging measures in these cases, focusing on patients’ “well-being” and “best interests.” Conclusions In this unique sample of cases involving conflict surrounding resuscitation and end-of-life care, references to “do everything” highlighted conflicts over quantity versus quality of life. These appeals were associated with signs of cognitive distress on the behalf of SDMs who were facing the prospect of a patient’s death, whereas physicians identified moral distress related to the prolongation of patients’ suffering through their use of life-sustaining interventions. This divergence in perspectives on death versus suffering was consistently the locus of conflict. These findings support the importance of tools such as the Serious Illness Conversation Guide that can be used by physicians to direct conversations on the patients’ goals, wishes, trade-offs, and to recommend a treatment plan that may include palliative care.
