Spermatozoa reach the fallopian tube during ovulation by traveling through the female reproductive tract mucus. This non‐Newtonian viscoelastic medium facilitates spermatozoon movement to accomplish fertilization or, in some cases, blocks spermatozoon movement, leading to infertility. While rheological properties are known to affect spermatozoon motility with in vitro models using synthetic polymers, their precise effects in vivo are understudied. This paper reviews the rheological measurements of reproductive tract mucus during ovulation in humans and model animals, focusing on viscosity and its potential (...) effect on spermatozoa. Mucus viscosity in the female reproductive tract's different compartments is poorly understood. While information on this subject is incomplete, most mammals appear to have a viscosity decrease along their female reproductive tracts. Based on this sparse information, we hypothesize that viscosity changes in female reproductive tracts may guide spermatozoa to eggs, a novel concept that could improve our understanding of reproductive biology.

Owen Flanagan argues that we are on the way to understanding consciousness and its place in the natural order.

Owen Flanagan argues in this book for a more psychologically realistic ethical reflection and spells out the ways in which psychology can enrich moral philosophy. Beginning with a discussion of such "moral saints" as Gandhi, Mother Teresa, and Oskar Schindler, Flanagan charts a middle course between an ethics that is too realistic and socially parochial and one that is too idealistic, giving no weight to our natures.

Consciousness emerges as the key topic in this second edition of Owen Flanagan's popular introduction to cognitive science and the philosophy of psychology....

If consciousness is "the hard problem" in mind science -- explaining how the amazing private world of consciousness emerges from neuronal activity -- then "the really hard problem," writes Owen Flanagan in this provocative book, is explaining how meaning is possible in the material world. How can we make sense of the magic and mystery of life naturalistically, without an appeal to the supernatural? How do we say truthful and enchanting things about being human if we accept the fact (...) that we are finite material beings living in a material world, or, in Flanagan's description, short-lived pieces of organized cells and tissue? Flanagan's answer is both naturalistic and enchanting. We all wish to live in a meaningful way, to live a life that really matters, to flourish, to achieve _eudaimonia_ -- to be a "happy spirit." Flanagan calls his "empirical-normative" inquiry into the nature, causes, and conditions of human flourishing _eudaimonics_. _Eudaimonics_, systematic philosophical investigation that is continuous with science, is the naturalist's response to those who say that science has robbed the world of the meaning that fantastical, wishful stories once provided. Flanagan draws on philosophy, neuroscience, evolutionary biology, and psychology, as well as on transformative mindfulness and self-cultivation practices that come from such nontheistic spiritual traditions as Buddhism, Confucianism, Aristotelianism, and Stoicism, in his quest. He gathers from these disciplines knowledge that will help us understand the nature, causes, and constituents of well-being and advance human flourishing. _Eudaimonics_ can help us find out how to make a difference, how to contribute to the accumulation of good effects -- how to live a meaningful life.

If we are material beings living in a material world -- and all the scientific evidence suggests that we are -- then we must find existential meaning, if there is such a thing, in this physical world. We must cast our lot with the natural rather than the supernatural. Many Westerners with spiritual inclinations are attracted to Buddhism -- almost as a kind of moral-mental hygiene. But, as Owen Flanagan points out in The Bodhisattva's Brain, Buddhism is hardly naturalistic. (...) In _The Bodhisattva's Brain_, Flanagan argues that it is possible to discover in Buddhism a rich, empirically responsible philosophy that could point us to one path of human flourishing. Some claim that neuroscience is in the process of validating Buddhism empirically, but Flanagan's naturalized Buddhism does not reduce itself to a brain scan showing happiness patterns. "Buddhism naturalized," as Flanagan constructs it, offers instead a fully naturalistic and comprehensive philosophy, compatible with the rest of knowledge -- a way of conceiving of the human predicament, of thinking about meaning for finite material beings living in a material world.

An expansive look at how culture shapes our emotions—and how we can benefit, as individuals and a society, from less anger and more shame The world today is full of anger. Everywhere we look, we see values clashing and tempers rising, in ways that seem frenzied, aimless, and cruel. At the same time, we witness political leaders and others who lack any sense of shame, even as they display carelessness with the truth and the common good. In How to Do (...) Things with Emotions, Owen Flanagan explains that emotions are things we do, and he reminds us that those like anger and shame involve cultural norms and scripts. The ways we do these emotions offer no guarantee of emotionally or ethically balanced lives—but still we can control and change how such emotions are done. Flanagan makes a passionate case for tuning down anger and tuning up shame, and he observes how cultures around the world can show us how to perform these emotions better. Through comparative insights from anthropology, psychology, and cross-cultural philosophy, Flanagan reveals an incredible range in the expression of anger and shame across societies. He establishes that certain types of anger—such as those that lead to revenge or passing hurt on to others—are more destructive than we imagine. Certain forms of shame, on the other hand, can protect positive values, including courage, kindness, and honesty. Flanagan proposes that we should embrace shame as a uniquely socializing emotion, one that can promote moral progress where undisciplined anger cannot. How to Do Things with Emotions celebrates the plasticity of our emotional responses—and our freedom to recalibrate them in the pursuit of more fulfilling lives. (shrink)

Human beings have the unique ability to consciously reflect on the nature of the self. But reflection has its costs. We can ask what the self is, but as David Hume pointed out, the self, once reflected upon, may be nowhere to be found. The favored view is that we are material beings living in the material world. But if so, a host of destabilizing questions surface. If persons are just a sophisticated sort of animal, then what sense is there (...) to the idea that we are free agents who control our own destinies? What makes the life of any animal, even one as sophisticated as Homo sapiens, worth anything? What place is there in a material world for God? And if there is no place for a God, then what hold can morality possibly have on us--why isn't everything allowed? Flanagan's collection of essays takes on these questions and more. He continues the old philosophical project of reconciling a scientific view of ourselves with a view of ourselves as agents of free will and meaning-makers. But to this project he brings the latest insights of neuroscience, cognitive science, and psychiatry, exploring topics such as whether the conscious mind can be explained scientifically, whether dreams are self-expressive or just noise, the moral socialization of children, and the nature of psychological phenomena such as multiple personality disorder and false memory syndrome. What emerges from these explorations is a liberating vision which can make sense of the self, agency, character transformation, and the value and worth of human life. Flanagan concludes that nothing about a scientific view of persons must lead to nihilism. (shrink)

The Geography of Morals is a work of extraordinary ambition: an indictment of the parochialism of Western philosophy, a comprehensive dialogue between cultural and psychological anthropology, recent work in empirical moral psychology, behavioral economics, and cross-cultural philosophy.

Traditional ideas about the basic nature of humanity are under attack as never before. The very attributes that make us human--free will, the permanence of personal identity, the existence of the soul--are being undermined and threatened by the current revolution in the science of the mind. If the mind is the brain, and therefore a physical object subject to deterministic laws, how can we have free will? If most of our thoughts and impulses are unconscious, how can we be morally (...) responsible for what we do? The Problem of the Soul shows the way out of these seemingly intractable paradoxes. Framing the conflict in terms of two dominant visions of the mind--the "manifest image" of humanistic philosophy and theology, and the scientific image--renowned philosopher Owen Flanagan demonstrates that there is, in fact, common ground, and that we need not give up our ideas of moral responsibility and personal freedom in order to have an empirically sound view of the human mind.

ABSTRACT Most theorists agree that our social order includes a distinctive legal dimension. A fundamental question is that of whether reference to specific legal phenomena always involves a commitment to a particular moral view. Whereas many philosophers advance the ‘positivist’ claim that any correspondence between morality and the law is just a function of political circumstance, natural law theorists insist that law is intrinsically moral. Each school claims the crucial advantage of consistency with our folk concept. Drawing on the notion (...) of dual character concepts, we develop a set of hypotheses about the intuitive relation between a rule’s moral and legal aspects. We then report a set of studies that conflict unexpectedly with the predictions by legal positivists. Intuitively, an evil rule is not a fully-fledged instance of law. (shrink)

In this essay we provide (1) an argument for why ethics should be naturalized, (2) an analysis of why it is not yet naturalized, (3) a defense of ethical naturalism against two fallacies—Hume’s and Moore’s—that ethical naturalism allegedly commits, and (4) a proposal that normative ethics is best conceived as part of human ecology committed to pluralistic relativism. We explain why naturalizing ethics both entails relativism and also constrains it, and why nihilism about value is not an especially worrisome for (...) ethical naturalists. The substantive view we put forth constitutes the essence of Duke Naturalism. (shrink)

In Dreaming Souls, Owen Flanagan provides both an accessible survey of the latest research on sleep and dreams and a compelling new theory about the nature and function of dreaming. Flanagan argues that while sleep has a clear biological function and adaptive value, dreams are merely side effects, 'free-riders', irrelevant from an evolutionary point of view. But dreams are hardly unimportant. Indeed, Flanagan argues that dreams are self-expressive, the result of our need to find or create meaning, (...) even when we are sleeping. (shrink)

Views of the self may be plotted on a set of coordinates. On the axis that runs from fragmentation to unity, Rorty and Rorty's Freud champion the decentered self while Wallwork, Taylor, and Ricoeur argue for a sovereign, unified self. On the other axis, which runs from the disengaged, inward-turning self to the engaged and "sedimented" self, Wallwork, would be positioned near Rorty, defending self-creation against the narrative identity affirmed by Taylor and Ricoeur. Despite his skepticism concerning the communitarian agenda (...) of the narrativists, Flanagan grants that the self is social and relational--a position further explored by Oliver, Stendahl, Deutsch, and Mack in "Selves, People, and Persons".

Todd Moody’s Zombie Earth thought experiment is an attempt to show that ‘conscious inessentialism’ is false or in need of qualification. We defend conscious inessentialism against his criticisms, and argue that zombie thought experiments highlight the need to explain why consciousness evolved and what function(s) it serves. This is the hardest problem in consciousness studies.

Flanagan (1991) was the first contemporary philosopher to suggest that a modularity of morals hypothesis (MMH) was worth consideration by cognitive science. There is now a serious empirically informed proposal that moral competence is best explained in terms of moral modules-evolutionarily ancient, fast-acting, automatic reactions to particular sociomoral experiences (Haidt & Joseph, 2007). MMH fleshes out an idea nascent in Aristotle, Mencius, and Darwin. We discuss the evidence for MMH, specifically an ancient version, “Mencian Moral Modularity,” which claims four (...) innate modules, and “Social Intuitionist Modularity,” which claims five innate modules. We compare these two moral modularity models, discuss whether the postulated modules are best conceived as perceptual/Fodorian or emotional/Darwinian, and consider whether assuming MMH true has any normative ethical consequences whatsoever. The discussion of MMH reconnects cognitive science with normative ethics in a way that involves the reassertion of the “is-ought” problem. We explain in a new way what this problem is and why it would not yield. The reason does not involve the logic of “ought,” but rather the plasticity of human nature and the realistic options to “grow” and “do” human nature in multifarious legitimate ways. (shrink)

Many philosophers believe that normative ethics is in principle independent of psychology. By contrast, the authors of these essays explore the interconnections between psychology and moral theory. They investigate the psychological constraints on realizable ethical ideals and articulate the psychological assumptions behind traditional ethics. They also examine the ways in which the basic architecture of the mind, core emotions, patterns of individual development, social psychology, and the limits on human capacities for rational deliberation affect morality.

There is a debate about the nature of addiction, whether it is a result of brain damage, brain dysfunction, or normal brain changes that result from habit acquisition, and about whether it is a disease. I argue that the debate about whether addiction is a disease is much ado about nothing, since all parties agree it is “unquestionably destructive.” Furthermore, the term ‘addiction’ has disappeared from recent DSM’s in favor of a spectrum of ‘abuse’ disorders. This may be a good (...) thing indicating more nuance in typing the heterogeneous phenomena we used to call ‘addiction’. (shrink)

This chapter presents a reflective, critical position toward the author’s own addiction and toward himself as an addict. It presents the question of whether addressing addiction as a disease is useful; the idea of addiction as a disease seems less useful in describing “what it is like” for the author than to say that his being was physically, psychologically, and relationally disordered. Despite his desires, he could not find a way to regain order and harmony within himself. It was only (...) the phenomenological possibility of feeling and being better that kept hope alive. The solution to addiction is social; other people who cared for the author personally, together with those with professional knowledge, assisted him in regaining some control that he alone had either lost or could not find.

McKay & Dennett (M&D) argue that positive illusions are a plausible candidate for a class of evolutionarily misbeliefs. I argue (Flanagan 1991; 2007) that the class of alleged positive illusions is a hodge-podge, and that some of its members are best understood as positive attitudes, hopes, and the like, not as beliefs at all.

Chapter 51 focuses on the subjective side of alcoholism, specifically about what memoirs of alcoholism teach about alcoholism, and argue that a common theme in many memoirs is that drinking, sometimes heavy drinking, a prerequisite of addiction, was modelled, endorsed, and eventually achieved in a way that involves deep identification, and also argues that alcoholic memoirs, even assuming that they suffer from objectivity problems such as the latter, nonetheless serve an important function, and not just whatever cathartic function they serve (...) for the author.

Consciousness and evolution are complex phenomena. It is sometimes thought that if adaptation explanations for some varieties of consciousness, say, conscious visual perception, can be had, then we may be reassured that at least those kinds of consciousness are not epiphenomena. But what if other varieties of consciousness, for example, dreams, are not adaptations? We sort out the connections among evolution, adaptation, and epiphenomenalism in order to show that the consequences for the nature and causal efficacy of consciousness are not (...) as dire as has sometimes been supposed.

Argues that many corporate executives have destroyed the value of their companies, cheated stockholders, employees, and the public, and compromised the integrity of financial markets and accountants while enriching themselves.

This volume offers a rich and accessible introduction to contemporary research on Buddhist ethical thought for interested students and scholars, yet also offers chapters taking up more technical philosophical and textual topics. A Mirror is For Reflection offers a snapshot of the present state of academic investigation into the nature of Buddhist Ethics, including contributions from many of the leading figures in the academic study of Buddhist philosophy. Over the past decade many scholars have come to think that the project (...) of fitting Buddhist ethical thought into Western philosophical categories may be of limited utility, and the focus of investigation has shifted in a number of new directions. This volume includes contemporary perspectives on topics including the nature of Buddhist ethics as a whole, karma and rebirth, mindfulness, narrative, intention, free will, politics, anger, and equanimity.

At the end of the 1990s, Brazil was faced with a potentially explosive HIV/AIDS epidemic. Through an innovative and multifaceted campaign, and despite initial resistance from multinational pharmaceutical companies, the government of Brazil was able to negotiate price reductions for HIV medications and develop local production capacity, thereby averting a public health disaster. Using interview data and document analysis, the authors show that the exercise of corporate social responsibility can be viewed in practice as a dynamic negotiation and an interaction (...) between multiple actors. Action undertaken in terms of voluntary CSR alone may be insufficient. This finding highlights the importance of a strong role for national governments and international organizations to pressure companies to perform better. (shrink)

The need for professionals to volunteer their time in crisis situations and to reach across time and culture in the service of humanitarian interventions will likely not abate in the near future. This article provides readers with multiple venues for considering the ethical dimensions present in crisis and humanitarian interventions. Core ethical concerns common to helping situations are magnified in crisis work. In addition, issues unique to the nature of volunteer and crisis work must also be considered. Using hypothetical case (...) examples, bioethical principles, and ethical decision-making models, helping professionals are encouraged to go beyond their particular ethical codes in contemplating ethically and clinically sensitive volunteering.

The Really Hard Problem: Meaning in a Material World is my attempt to explain whether and how existential meaning is possible in a material world, and how such meaning is best conceived naturalistically. Neuroexistentialism conceives of our predicament in accordance with Darwin plus neuroscience. The prospects for our kind of being-in-the-world are limited by our natures as smart but fully embodied short-lived animals. Many find this picture disenchanting, even depressing. I respond to four criticisms of my relentless upbeat naturalism: that (...) naturalism can make no room for norms, for values; that I overvalue truth at the expense of happiness; that I underestimate the extent to which supernaturalism has made peace with naturalism; and that I can give no account for why humans as finite animals should want to overcome our given natures and seek impersonal, self-transcendent value.
