The concept of 'levels of organization' has come under fire recently as being useless for scientific and philosophical purposes. In this paper, we show that 'levels' is actually a remarkably resilient and constructive conceptual tool that can be, and in fact is, used for a variety of purposes. To this effect, we articulate an account of the importance of the levels concept seen in light of its status as a major organizing concept of biology. We argue that the usefulness of (...) ‘levels’ is best seen in the heuristic contributions the concept makes to treating and structuring scientific problems. We illustrate this with two examples from biological research. (shrink)

Despite its pervasiveness, the concept of ‘levels of organization’ has received relatively little attention in its own right. I propose here an emerging approach that posits ‘levels’ as a fragmentary concept situated within an interest-relative matrix of operational usage within scientific practice. To this end I propose one important component of meaning, namely the epistemic goal motivating the term’s usage, which recovers a remarkably conserved and sufficiently unifying significance attributable to ‘levels’ across different instances of usage. This epistemic goal, to (...) provide structure to scientific problems, delegates tasks whose execution generates the term’s expressed content in a given instance. This treatment of levels does not diminish the concept’s general importance to science, but rather allows for its use in, and usefulness for, scientific practice to be better contextualized to particular tasks encompassing varying breadths of activity.

Despite the ubiquity of “levels of organization” in the scientific literature, a nascent “levels skepticism” now claims that the concept of levels is an inherently flawed, misleading, or otherwise inadequate notion for understanding how life scientists produce knowledge about the natural world. However, levels skeptics rely on the maligned “layer-cake” account of levels stemming from Oppenheim and Putnam’s defense of the unity of science for their critical commentary. Recourse to layer-cake levels is understandable, as it is arguably the default conception (...) of levels in philosophy. However, relying on this conception of levels undermines the initial plausibility of general dismissals of the concept, because the problems skeptics identify within the “basic idea” of the concept “levels” are merely ones already widely acknowledged in this conception. I illustrate this “guilt by association” by looking at the embedded role of “levels” in articulating intertheoretical reductionism during the latter part of the 20th century. I conclude by suggesting a methodological framework focusing on local usage patterns as a promising means for future analysis of the levels concept. (shrink)

Following its initial development in the 1920’s and 1930’s, by mid-century the concept of “levels of organization” began to disperse throughout the life science textbook literature. Among other early textbooks that first applied the levels concept, Eugene P. Odum’s usage of the notion in his textbook series Fundamentals of Ecology (and his later series Ecology) stands out due to the marked emphasis placed on the concept as a foundational, erotetically-oriented organizing principle. In this paper, I examine Odum’s efforts toward advocating (...) the levels concept in ecology in light of the concept’s wider uptake in biology around that time. (shrink)

Understanding the relationship between wilderness outings and the resulting experience has been a central theme in resource-based, outdoor recreation research for nearly 50 years. The authors provide a review and synthesis of literature that examines how people, over time, build relationships with wilderness places and express their identities as consequences of multiple, ongoing wilderness engagements (i.e., continued participation). The paper reviews studies of everyday places and those specifically protected for wilderness and backcountry qualities. Beginning with early origins and working through (...) contemporary research the authors synthesize what diverse social scientists have learned about the long-term and continual nature of wilderness participation and its impact on the formation of identity. The thrust of the paper points researchers, planners, and managers in non-traditional directions and reframes goals and objectives for visitor planning and management in wilderness and other protected areas.

Transcendental arguments are not popular in contemporary philosophy of science. They are typically seen as antinaturalistic and incapable of providing explanatory force in accounting for natural phenomena. However, when viewed as providing intelligibility to complicated concepts used in scientific reasoning, a concrete and productive role is recoverable for transcendental reasoning in philosophy of science. In this article I argue that the resources, and possibly the need, for such a role are available within a thoroughly naturalistic framework garnered from the work (...) of Hasok Chang and William Wimsatt.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 27.1 (2003) 62-79 [Access article in PDF] Literature Itself:The New Criticism and Aesthetic Experience Daniel Green I AFTER ALMOST TWO DECADES of tumult and transformation in university departments that still claim literature as part of their disciplinary domain, what is most remarkable about literary study at the beginning of the twenty-first century is how similar it is to what passed for such study at the (...) beginning of the twentieth century. Like philology one hundred years ago, academic literary study today—at least at the most eminent universities and in the most prestigious journals—is a highly esoteric activity, unlikely to appeal to anyone outside its own "professional" boundaries, anyone whose foremost interest in works of literature is simply to read them. It is, therefore, an endeavor that could hardly exist outside the university's institutional protection, and it is most strikingly concerned not with the appreciation of the intrinsic qualities of literature but with the historical and cultural "knowledge" that can be acquired from works of literature through a special kind of analysis. The effort, chronicled by Gerald Graff in Professing Literature, to make "literature itself" the focus of academic study and to establish "aesthetic criticism" as the primary mode of literary study must surely be judged a failure, the current academic scene clearly dominated by the sort of scholars Graff terms "investigators." 1But of course the motives for rejecting the merely literary as a focus of study are quite different among current scholarly investigators as compared to the philologists of 1901. The attitude of the latter can probably be captured in the words of one of them quoted by Graff: "Why then waste time and brains in thrashing over again something which is after all only subjective opinion? Mere aesthetic theorizing [End Page 62] should be left to the magazine writer or to the really gifted critic" (p. 124). Such "researchers" did not deny the value of reading works of literature; they simply considered this value to be essentially "subjective," not an appropriate object of academic scrutiny. While these remarks do imply some condescension toward the "really gifted critic" and this critic's "mere aesthetic theorizing," they do not repudiate the very idea of an aesthetic approach to literature. The present generation of academics engaged in the investigation of literature, on the other hand, have repudiated the aesthetic approach, either explicitly, through the well-publicized critiques of the canon, of the very notion of the great work, or of the remaining approaches still associated with New Criticism, or implicitly through the gradual establishment of cultural investigation as the new norm for the professional training of graduate students and as the dominant mode of analysis in the influential journals. Moreover, the primary motive behind the renunciation of the aesthetic has more to do with politics than with methodology: for these scholars, the aesthetic is literally useless, quite irrelevant to the paramount goal of "intervening" in a continuing ideological struggle that is thought to be the main business of the university scholar.In the context of the history of modern literary criticism (as opposed to the history of the American university), the current situation mirrors that which prompted the emergence of The New Criticism in the 1930s. Although Vincent Leitch identifies "the evocative mode of Impressionist criticism, the moralism of Neo-Humanism, the anti-modernist cultural criticism of Mencken and Van Wyck Brooks," as well as the "sociologizing" of Marxist criticism" as the collective bêtes noires of the New Critics, it was clearly the latter they considered to be the most unwelcome. Not only had it effectively eclipsed the other practices, but it could be said to have exhibited most of those characteristics against which New Criticism expressed the deepest antipathy. 2 Compared to the close reading New Critics would espouse, Marxist criticism was superficial, willing to settle for the most readily available interpretation (according to the Marxists' own critical assumptions), moralistic, committed to the idea that the best literature was that which could be shown to be good for you, historicist, concerned to place works...

David Marr's theory of vision has been a rich source of inspiration, fascination and confusion. I will suggest that some of this confusion can be traced to discrepancies between the way Marr developed his theory in practice and the way he suggested such a theory ought to be developed in his explicit metatheoretical remarks. I will address claims that Marr's theory may be seen as an optimizing theory, along with the attendant suggestion that optimizing assumptions may be inappropriate for cognitive (...) mechanisms just as anti-adaptationists have argued they are inappropriate for other physiological mechanisms. I will discuss the nature of optimizing assumptions and theories. Considering various difficulties in identifying and assessing optimizing assumptions, I will suggest that Marr's theory is not purely an optimizing theory and that reaction to Marr on this issue prompts interesting considerations for the development of inter-disciplinary constraints in the cognitive and brain sciences.

In a 2007 interview, then senator and presidential candidate, Barack Obama, called Reinhold Niebuhr, “one of my favorite philosophers.” When his interviewer, David Brooks, followed by asking, “What do you take away from him?” Obama answered, “I take away the compelling idea that there’s serious evil in the world, and hardship and pain.

I take away . . . the sense we have to make these efforts knowing they are hard, and not swinging from naïve idealism to bitter realism.”1 One part of Niebuhr’s political theology that Obama has clearly embraced is Niebuhr’s justification ..

Nietzsche values intellectual honesty, but is dubious about what he calls the will to truth. This is puzzling since intellectual honesty is a component of the will to truth. In this paper, I show that this puzzle tells us something important about how Nietzsche conceives of our pursuit of truth. For Nietzsche, those who pursue truth occupy unstable ground, since being honest about the ultimate reasons for that pursuit would mean that truth could no longer satisfy the important human needs (...) it satisfies at present. We can pursue truth, or be honest about what in us is served by such a pursuit, but not both. Nietzsche aims to show that understanding and owning up to this instability is the sort of affirmation of human life to which we ought to aspire, and is the price we pay for being free from otherworldly morality.

It is shown that completely entangled two-particle quantum states are simultaneous eigenstates of a large set of commuting, nonlocal observables, a characterization that generalizes to multiparticle systems. This leads to a nonstatistical proof of the Bell-EPR no-hidden-variable theorem for two-particle systems and to a family of multiparticle generalizations of the three-particle system of Greenberger, Horne, and Zeilinger.

Current medical and legal literature generally favors a definition of death based on total cessation of brain functioning. It does not, however, supply the reasoning for this recommendation. None of the arguments for whole-brain death is convincing; there exists, however, a satisfactory rationale for identifying death with cortical death. Policymakers should refrain from endorsing any of these arguments, focussing instead on the pragmatic tasks involved in guiding medical care at the end of life.

If we think of political progress as indexed to some permanent standard, and then agree that it is Nietzsche who dispels the authority of any such standard, then we may perhaps conclude that after Nietzsche, progress is ruled out. I want to show, however, that we find in Nietzsche comfort for a continued vision of human progress through engaged political action. I suggest that we look to Derrida and Rorty as offering a view of a post-Nietzschean democracy the engine of (...) which is an account of ameliorative progress that is at home in the Enlightenment tradition while avoiding its universalist pretensions.

Nietzsche, Foucault, and Rorty are each ethical thinkers in that widest sense that concerns questions of who we ought to be, and each seeks to answer those questions through accounts of self-creation that are distinguished by the style and scope of embeddedness in some community they rely on. Nietzsche’s is a middle-ground position between Rorty and Foucault since he offers an affirmation of community, on grounds that Rorty might accept, without acquiescence to the status quo, a concern for Foucault. Nietzsche (...) aims to place himself in a community, but one in part defined by its vigilance in identifying its blind spots, in knowing that it does not always know itself. In particular, I would like to say that Rorty misses the force of Nietzsche’s views on self-creation and the affirmation of community because Rorty mischaracterizes Nietzsche’s perspectivism by construing it along narrative rather than affective or physiological lines.

Nietzsche is famously a critic of Mitleid, compassion or pity. He claims that because it must condemn all suffering, a morality of compassion is unable to recognize the ennobling aspects of suffering, and so is unable to recognize what is good and noble about those aspects of the human condition susceptible to suffering. Compassion thus robs our finitude of significance. Alongside his criticisms of compassion, however, at numerous places we see Nietzsche distinguishing between conceptions of compassion made different by the (...) different forms of life in which they are implicated. “Compassion,” for Nietzsche, is too broad a term, capturing a range of moral phenomena and their attendant eliciting conditions, deep...

Representing a variety of interpretive strategies, and looking closely at a wide range of Nietzsche’s works, the papers in this issue are nevertheless united by a common concern to make clear whether and how our understanding of Nietzsche is improved by paying closer attention to his treatment of virtue. For Nietzsche’s overlapping projects of interrogating inherited values and of envisioning forms of human life outside of the present moral economy of guilt and retribution both grow out of concerns central to (...) virtue ethics. That is, Nietzsche is asking whether morality in its present state is good for human beings, where what counts as good has to do with the kind of creatures we are, and so what it takes for us to flourish.

The Western evangelical church has lost both the passion for and the art of reading Scripture orally in worship. This exploration of the biblical roots of reading Scripture orally examines both the Old and the New Testament evidence, noting particularly the paradigm established by Moses in Deuteronomy 31:9-13 and modeled by Ezra in Nehemiah 8 that reflects the formative reading of Scripture. Since literacy was limited and few had access to written copies of the Scriptures in ancient Israel and in (...) the early church, public hearing of the Word of God provided the primary means of inspiration and spiritual formation. The essay concludes with a discussion of the implications of the biblical evidence for evangelicals today, including specific guidelines for developing the art of reading the Scriptures in corporate worship.

Recent years have seen increased interest in Friedrich Nietzsche's middle period works, as scholars have turned to Human, All Too Human, Daybreak, and The Gay Science in exploring Nietzsche's turn toward naturalism and the roots of his mature criticisms of morality.

Often viewed as a series of disconnected intellectual experiments that evince Nietzsche's rapid, not always linear, development over the period of their publication, the middle (...) period works are, Meyer argues, instead best understood as a consciously constructed dialectical Bildungsroman or narrative of self-education.

Throughout his writings, Nietzsche problematizes self-knowledge, trying to displace rather than satisfy our drive for it. Describing self-knowledge as an ideal only for a certain kind of human being, he writes that it is the community that says, “‘you shall be knowable, express your inner nature by clear and constant signs—otherwise you are dangerous [...]. We despise the secret and unrecognizable.—Consequently, you must consider yourself knowable, you may not be concealed from yourself, you may not believe that you change’”.1 And (...) he argues that what we call self-knowledge develops in the first instance not in order that we might know ourselves, but only in response to our need to...

Edmund Burke, long considered modern conservatism's founding father, is also widely believed to be an opponent of empire. However, Daniel O'Neill turns that latter belief on its head. This fresh and innovative book shows that Burke was a passionate supporter and staunch defender of the British Empire in the eighteenth century, whether in the New World, India, or Ireland. Moreover--and against a growing body of contemporary scholarship that rejects the very notion that Burke was an exemplar of conservatism--O'Neill demonstrates (...) that Burke's defense of empire was in fact ideologically consistent with his conservative opposition to the French Revolution. Burke's logic of empire relied on two opposing but complementary theoretical strategies: Ornamentalism, which stressed cultural similarities between "civilized" societies, as he understood them, and Orientalism, which stressed the putative cultural differences distinguishing "savage" societies from their "civilized" counterparts. This incisive book also shows that Burke's argument had lasting implications, as his development of these two justifications for empire prefigured later intellectual defenses of British imperialism"--Provided by publisher.

Conventional quantum mechanics with a complex Hilbert space and the Born Rule is derived from five axioms describing experimentally observable properties of probability distributions for the outcome of measurements. Axioms I, II, III are common to quantum mechanics and hidden variable theories. Axiom IV recognizes a phenomenon, first noted by von Neumann (in Mathematical Foundations of Quantum Mechanics, Princeton University Press, Princeton, 1955) and independently by Turing (Teuscher and Hofstadter, Alan Turing: Life and Legacy of a Great Thinker, Springer, Berlin, (...) 2004), in which the increase in entropy resulting from a measurement is reduced by a suitable intermediate measurement. This is shown to be impossible for local hidden variable theories. Axiom IV, together with the first three, almost suffice to deduce the conventional rules but allow some exotic, alternatives such as real or quaternionic quantum mechanics. Axiom V recognizes a property of the distribution of outcomes of random measurements on qubits which holds only in the complex Hilbert space model. It is then shown that the five axioms also imply the conventional rules for any finite dimension. (shrink)

Nietzsche criticizes the shared suffering of compassion as a basis for ethics, yet his challenge to overcome compassion seeks not to extinguish all fellow feeling but instead urges us to transform the way we relate to others, to learn to share not suffering but joy. For Schopenhauer, we act morally when we respond to another’s suffering, while we are mistrustful of the joys of others. Nietzsche turns to the type of relationality exempli!ied by friendship, understood as shared joy, in order (...) to help him to articulate his ethical ideal for human beings. (shrink)

A critic of metaphysically robust accounts of the human self, Nietzsche means not to do away with the self entirely, but to reimagine it. He pursues an account according to which the unity of the self is born out of a coherent organization of drives and yet is not something other than that organization. Readers of Nietzsche have pointed to a so-called “lack of fit” between this theoretical account of the self, according to which the self is nothing apart from (...) the organization of drives, and Nietzsche’s practical account of human agency, which often seems to require that the self be something more than mere drives. I suggest Nietzsche’s interest in Greek agonistic norms of contest sheds light on this apparent incongruity. Agonistic relationships, insofar as they cultivate contest among diverse forces, are for Nietzsche one appropriate model for the subjectivity of beings whose psychology is similarly characterized by contest among diverse forces—that is, beings like us.

This article is the first in-depth analysis of the direct intellectual engagement between one of America's most important Founding Fathers, John Adams, and the work of the leading modern feminist, Mary Wollstonecraft.

Daniel R. Brooks and E. O. Wiley have proposed a theory of evolution in which fitness is merely a rate determining factor. Evolution is driven by non-equilibrium processes which increase the entropy and information content of species together. Evolution can occur without environmental selection, since increased complexity and organization result from the likely capture at the species level of random variations produced at the chemical level. Speciation can occur as the result of variation within the species which decreases (...) the probability of sharing genetic information. Critics of the Brooks-Wiley theory argue that they have abused terminology from information theory and t thermodynamics. In this paper I review the essentials of the theory, and give an account of hierarchical physical information systems within which the theory can be interpreted. I then show how the major conceptual objections can be answered. (shrink)

In this essay we shall examine the contemporary jurisprudential thinking and legal precedents surrounding the issue of the sanctionability of pornography. We shall catalogue them by their logical presumptions, such as whether they view pornography as speech or act, whether they view pornography as obscenity, political hate-speech or anomalous other, whether they would scrutinize legislation governing pornography by a balancing of the harm of repression against the harm of permission, and who exactly they view as the victims.We shall take a (...) special interest in the most recent, but unsuccessful, attempt by a subgroup of feminists to proscribe pornography by treating it as neither political speech nor sexual speech but speech which causes harm which is both political and sexual. They would like it to be considered as a special kind of odious propaganda undeserving of protection because it promulgates a mental state conducive to criminal activity, and hence is criminal in and of itself. However, the repression of propaganda, even odious propaganda, is not so easily accomplished in this country. (shrink)

In this chapter, we will summarize recent empirical results highlighting how different groups of people solve pure coordination games. Such games are traditionally studied in behavioural economics, where two people need to coordinate without communicating with each other. Our results suggest that coordination choices vary across groups of people, and that people can adapt flexibly to these differences in order to coordinate between groups. We propose that pure coordination games are a useful empirical platform for studying aspects of mindshaping. Drawing (...) on existing psychological literature on alignment during interactions, we suggest that experience of successful interaction leads people to develop aligned intuitions about what is relevant and appropriate that support coordination when interaction and communication is not possible. Consistent with arguments made in the literature on mindshaping we believe that such alignment is more important for coordination than mindreading inferences about mental states, and indeed that mindreading is instead a form of coordination behaviour that is dependent upon intuitive alignment.

Many modern conservatives and feminists trace the roots of their ideologies, respectively, to Edmund Burke and Mary Wollstonecraft, and a proper understanding of these two thinkers is therefore important as a framework for political debates today. According to Daniel O’Neill, Burke is misconstrued if viewed as mainly providing a warning about the dangers of attempting to turn utopian visions into political reality, while Wollstonecraft is far more than just a proponent of extending the public sphere rights of man to (...) include women. Rather, at the heart of their differences lies a dispute over democracy as a force tending toward savagery or toward civilization. Their debate over the meaning of the French Revolution is the place where these differences are elucidated, but the real key to understanding what this debate is about is its relation to the intellectual tradition of the Scottish Enlightenment, whose language of politics provided the discursive framework within and against which Burke and Wollstonecraft developed their own unique ideas about what was involved in the civilizing process.

I make a proposal about what wondering is and how it differs from other mental phenomena like curiosity. I argue that, though it's tempting to analyze wondering as a desire to know the answer to the question one wonders about, that would be wrong, since wondering is an activity rather than a state, i.e., something we do. I also argue that wondering about a question needn't even essentially involve a desire to know the answer to that question, even as a (...) necessary part of what rationalizes the wondering. Instead, on my account, to wonder about a question is to consider various possible answers as possible answers, guided by mechanisms whose function is to make the subject epistemically better off with respect to those answers, and which considering ceases at least when a person is consciously certain of the answer to their question. This allows wondering to not be objectionably metacognitive, and allows us to make sense of cases in which the motivating desire isn't to know an answer but just to wonder itself. (shrink)

Traditionally, theories of concepts in psychology assume that concepts are a single, uniform kind of mental representation. But no single kind of representation can explain all of the empirical data for which concepts are responsible. I argue that the assumption that concepts are uniformly the same kind of mental structure is responsible for these theories’ shortcomings, and outline a pluralist theory of concepts that rejects this assumption. On pluralism, concepts should be thought of as being constituted by multiple representational kinds, (...) with the particular kind of concept used on an occasion being determined by the context. I argue that endorsing pluralism does not lead to eliminativism about concepts as an object of scientific interest. (shrink)

It is almost universally agreed that the main business of commonsense psychology is that of providing generally reliable predictions and explanations of the actions of others. In line with this, it is also generally assumed that we are normally at theoretical remove from others such that we are always ascribing causally efficacious mental states to them for the purpose of prediction, explanation and control. Building on the work of those who regard our primary intersubjective interactions as a form of 'embodied (...) practice', I defend a secondpersonal approach in this paper. (shrink)

The principle that each person is his own property occupies an almost axiomatic status in right-wing liberal thought as well as in some egalitarian theories. I reject any, full or partial, notion of property with respect to oneself by showing that any appeal and any justifiability which may be associated with self-ownership can at most serve to ground rights which are demonstrably non-property rights. As a contrast to self ownership, I introduce the non-proprietarian notion of Original Freedom. I compare the (...) two with respect to the control, income, and transfer aspects of ownership and suggest that Original Freedom is the more intuitively acceptable. (shrink)

I argue that, insofar as we endorse the general idea that desires play an important role in well-being, we ought to believe that their significance for well-being is derived from a pair of more fundamental attitudes: attraction and aversion. Attraction has wholly positive significance for well-being, and aversion has wholly negative significance for well-being. Desire satisfaction and frustration have significance for well-being insofar as the relevant desires involve some combination of attraction and aversion. I defend these claims by illustrating how (...) our desires can be asymmetrical. They can have greater positive than negative significance for well-being, or vice versa. (shrink)
