In this essay, Riggs demonstrates how heterosexism shapes foster-care assessment practices in Australia. Through an examination of lesbian and gay foster-care applicants’ assessment reports and with a focus on the heteronormative assumptions contained within them, Riggs demonstrates that foster-care public policy and research on lesbian and gay parenting both promote the idea that lesbian and gay parents are always already “just like” heterosexual parents. To counter this idea of “sameness,” Riggs proposes an approach to both assessing and (...) researching lesbian and gay parents that privileges the specific experiences of lesbians and gay men and resists the heterosexualization of lesbian and gay families by focusing on some potentially radical differences shaping lesbian and gay lives.

Jonathan Kvanvig's book, The Value of Knowledge and the Pursuit of Understanding (Kvanvig, 2003), is a wonderful example of doing epistemology in a style that Kvanvig himself has termed "value−driven epistemology." On this approach, one takes questions about epistemic value to be central to theoretical concerns, including the concern to provide an adequate account of knowledge. This approach yields the demand that theories of knowledge must provide, not just an adequate account of the nature of knowledge, but also an account (...) of the value of knowledge. Given the near−universal assumption that knowledge has a special kind of value, this demand seems reasonable, though surprisingly hard to satisfy. Another consequence of this approach to doing epistemology is that certain assumptions about epistemic value, like what sorts of things have it and what sorts of things don't, and where such value comes from, become much more salient to the epistemic enterprise. In his book, Kvanvig challenges the assumption that knowledge has some unique store of epistemic value. And he investigates the matter by asking questions about what the bearers of epistemic value are and where they get it. He concludes, of course, that knowledge as we have come to conceive it in 21st century epistemology has no such special value. (shrink)

This paper reports on a rhetorical analysis of interviews with fifteen white Australian citizens who had undertaken offshore commercial surrogacy in India. Extending previous research, the findings suggest that genetic relatedness was valorized, and surrogacy constructed as a less tenuous route to family formation. The paper concludes with a discussion of the need for further research on 1) how the contentious nature of offshore commercial surrogacy may prevent full consideration of its ethical implications, 2) the differing belief systems between India (...) and Australia in terms of children as alienable objects, and 3) ongoing consideration of how and when genetic-relatedness is made to matter.

Current epistemological dogma has it that the twin goalsof believing truths and avoiding errors exhaust our cognitive aspirations.On such a view, (call it the TG view) the only evaluationsthat count as genuinely epistemological are those that evaluatesomething (a belief, believer, set of beliefs, a cognitivetrait or process, etc.) in terms of its connection to thesetwo goods. In particular, this view implies that all theepistemic value of knowledge must be derived from thevalue of the two goals cited in TG. I argue (...) thatthis implication is false, and thus that the TG view must be abandoned. I propose a candidate to replacethe TG view that makes better sense of the value ofknowledge. (shrink)

It is nearly universally acknowledged among epistemologists that a belief, even if true, cannot count as knowledge if it is somehow largely a matter of luck that the person so arrived at the truth. A striking feature of this literature, however, is that while many epistemologists are busy arguing about which particular technical condition most effectively rules out the offensive presence of luck in true believing, almost no one is asking why it matters so much that knowledge be immune from (...) luck in the first place. I argue that the best explanation for the consensus that luck undermines knowledge is that knowledge is, complications aside, credit-worthy true believing. To make this case, I develop both the notions of luck and credit, and sketch a theory of knowledge in those terms. Furthermore, this account also holds promise for being able to solve the “value problem” for knowledge, and it explains why both internal and external conditions are necessary to turn true belief into knowledge.

Abstract: Open-mindedness is typically at the top of any list of the intellectual or "epistemic" virtues. Yet, providing an account that simultaneously explains why open-mindedness is an epistemically valuable trait to have and how such a trait is compatible with full-blooded belief turns out to be a challenge. Building on the work of William Hare and Jonathan Adler, I defend a view of open-mindedness that meets this challenge. On this view, open-mindedness is primarily an attitude toward oneself as a believer, (...) rather than toward any particular belief. To be open-minded is to be aware of one's fallibility as a believer, and to acknowledge the possibility that anytime one believes something, one could be wrong. In order to see that such an attitude is epistemically valuable even to an already virtuous agent, some details of the skills and habits of the open-minded agent are elucidated. (shrink)

This paper focuses on several issues that arise in Miranda Fricker?s book Epistemic injustice surrounding her claims about our (moral) culpability for perpetrating acts of testimonial injustice. While she makes frequent claims about moral culpability with respect to specific examples, she never addresses the issue in its full generality, and we are left to extrapolate her general view about moral culpability for acts of testimonial injustice from these more restricted and particular claims. Although Fricker never describes testimonial injustice in such (...) terms, I argue that the fundamental wrong done in acts of testimonial injustice is a form of negligence. Once we understand testimonial injustice in this way, it is easier to see when and why we are culpable for perpetrating such injustices. Indeed, explicitly recognizing testimonial injustice as a form of negligence solves several problems for Fricker?s view, which are elucidated briefly along the way. However, construing testimonial injustice as a form of negligence has a cost as well. It highlights the fact that the normative core of Fricker?s view is deontological, rather than virtue-theoretic. Fricker claims to be offering a theory of the virtue of testimonial justice along the model of current virtue theories in epistemology, yet it seems that there is no compelling reason to think of what she has offered as a virtue theory, at least not on the model of virtue theories that one finds in epistemology. This is not to say that her view is any less plausible for not being a virtue theory. But calling it a virtue theory affects how one interprets its various claims, and tends to lead one away from, rather than toward, a proper understanding of the deep deontological nature of her account.

It will startle no one to hear that there is widespread disagreement among philosophers about the nature and criteria of epistemic justification. There are many distinct notions of epistemic justification, distinguished from one another in a bewildering variety of ways. There are internalist justification, externalist justification, coherentist justification, foundationalist justification, deontic justification, consequentialist justification, propositional justification, doxastic justification, personal justification, situational justification, objective justification, subjective justification, cognitive justification, and structural justification. None of these is quite equivalent to another, yet each (...) is proposed as a way in which something can be epistemically justified. (shrink)

In this paper I defend the theory that knowledge is credit-worthy true belief against a family of objections, one of which was leveled against it in a recent paper by Jennifer Lackey. In that paper, Lackey argues that testimonial knowledge is problematic for the credit-worthiness theory because when person A comes to know that p by way of the testimony of person B, it would appear that any credit due to A for coming to believe truly that p belongs to (...) the testifier, B, rather than the hearer, A. If so, then knowledge would appear not to be a matter of credit for true belief. I think that the problem this raises actually has little to do with the fact that the knowledge comes by way of testimony, and that similar objections can be formulated in terms of perceptual and memorial knowledge. I will attempt to neutralize these objections by drawing a distinction between credit as praiseworthiness and credit as attributability. (shrink)

Reliabilism has come under recent attack for its alleged inability to account for the value we typically ascribe to knowledge. It is charged that a reliably-produced true belief has no more value than does the true belief alone. I reply to these charges on behalf of reliabilism; not because I think reliabilism is the correct theory of knowledge, but rather because being reliably-produced does add value of a sort to true beliefs. The added value stems from the fact that a (...) reliably-held belief is non-accidental in a particular way. While it is widely acknowledged that accidentally true beliefs cannot count as knowledge, it is rarely questioned why this should be so. An answer to this question emerges from the discussion of the value of reliability; an answer that holds interesting implications for the value and nature of knowledge. (shrink)

forthcoming 2007 in New Waves in Epistemology, Vincent Hendricks & Duncan Pritchard, eds.

It is generally assumed that there are (at least) two fundamental epistemic goals: believing truths, and avoiding the acceptance of falsehoods. As has been often noted, these goals are in conflict with one another. Moreover, the norms governing rational belief that we should derive from these two goals depend on how we weight them relative to one another. However, it is not obvious that there is one objectively correct weighting for everyone in all circumstances. Indeed, as I shall argue, it (...) looks as though there are circumstances in which a range of possible weightings of the two goals are all equally epistemically rational. (shrink)

Current epistemological dogma has it that the twin goalsof believing truths and avoiding errors exhaust our cognitive aspirations. On such a view, (call it the "TG view") the only evaluations that count as genuinely epistemological are those that evaluate something (a belief, believer, set of beliefs, a cognitive trait or process, etc.) in terms of its connection to these two goods. In particular, this view implies that all the epistemic value of knowledge must be derived from the value of the (...) two goals cited in TG. I argue that this implication is false, and thus that the TG view must be abandoned. I propose a candidate to replace the TG view that makes better sense of the value of knowledge. (shrink)

There are good reasons for pursuing a theory of knowledge by way of understanding the connection between knowledge and luck. Not surprisingly, then, there has been a burgeoning of interest in “luck theories” of knowledge as well as in theories of luck in general. Unfortunately, “luck” proves to be as recalcitrant an analysandum as “knows.” While it is well worth pursuing a general theory of luck despite these difficulties, our theory of knowledge might be made more manageable if we could (...) find a more restricted notion that captured the core phenomena of luck that are relevant to whether or not someone knows. This essay makes the attempt to delineate such a notion, called “mere coincidence.”. (shrink)

Coherence theorists have universally defined justification as a relation only among (the contents of) belief states, in contradistinction to other theories, such as some versions of founda­tionalism, which define justification as a relation on belief states and appearance states.

Whilst feminist commentators have long critiqued surrogacy as a practice of commodification, surrogacy as a mode of family formation continues to grow in popularity. In this paper we explore public representations of surrogacy through a discourse analytic reading of submissions made in Australia to an Inquiry regarding surrogacy legislation. The findings suggest that many submissions relied upon normative understandings of surrogates as either ‘good women’ or ‘bad mothers’. This is of concern given that such public representations may shape the views (...) of those who utilize surrogacy services in ways that limit attention to the ethics of surrogacy. (shrink)

I am interested in epistemic virtues for reasons rather different than most. I do not offer a virtue theory of anything, I don't argue that we can solve various long−standing problems in epistemology by appeal to epistemic virtues, nor am I an opponent of any of these things (though I certainly find some of these projects more plausible than others.) Rather, my interest in the epistemic virtues stems from a long−standing commitment to epistemic value pluralism, and a belief that, until (...) recently, epistemology has been stifled by an implicit commitment to the hegemony of truth in the realm of epistemic value. Since the language of epistemic virtue theory adds a welcome richness to the vocabulary of epistemic evaluation, I find it appealing for that reason at least. (shrink)

This chapter contains sections titled: Meet the Celebrity Moms How to be a Good Mother Working Mothers How to be a Bad Mother Conclusion: Mothering as Boring Notes.

Fiona Allon writes that “ home, now more than ever, is seen as firmly connected to the world of politics and economics, as actively shaped and defined by the public sphere rather than existing simply as a refuge from it.” 1 From this perspective, claims to home as they are located in a relationship to claims of both national and local belonging are often a contested site within Australia, where notions of who is seen to be at home in Australia (...) are constantly being challenged and reworked. Structured around the desire amongst white people to retain Australia as a “white nation,” claims to home may be seen as operating in complex ways in regards to the rights that arise from the ongoing existence of Indigenous sovereignties, and the politics surrounding levels of immigration from groups of people perceived as belonging to minority racial groups. In this context, the notion of home is frequently drawn upon in relation to both how people perceive the way in which they, and others, belong in a country, and this raises questions surrounding who is legitimately able to call Australia home. Such discourses of home evoke feelings of ownership in people who feel that they have a legitimate claim to a country for reasons primarily of race or location of birth. In Australia, despite the powerful presence and voice of Indigenous peoples, popular perceptions of the country tend to place such homely rights firmly in the laps of white people, who, through images of white nuclear families in front of white picket fences, perceive themselves as already and rightfully at home in Australia. Yet such conceptions of Australia are not accepted without struggle. Notions of home are very much contested, especially in terms of Indigenous sovereignty and non-white immigration, both of which question the legitimacy of a normatively white Australia. Such ideas of home as being a contested space in which issues of national belonging are played out in Australia were seen quite clearly in relation to the 2005 Cronulla riots, in which thousands of white Australians gathered around Cronulla beach, shouting at and threatening those located as “Lebanese Muslim” people. The people involved in the riots made it quite clear that whilst Australia was a home for them, it ought not to be home to people who were identified as Lebanese Muslims. Such racist opinions exemplified the fact that Australia is seen to be a white country, and therefore as a legitimate home to white people rather than to non-white minority groups or even to Indigenous Australians. This is discussed in more detail later in this paper. (shrink)

Since the late 2000s trans pregnancy has received increasing public and academic attention, and stories of the ‘pregnant man’ have become a media staple. Existing research has critiqued such spectacularization and the supposed tension between maleness, masculinity, and pregnancy that underpins it. Extending that work, this article draws on interview data from an international study of trans reproductive practices and analyzes participants' experiences of being, and expecting themselves to be, perceived in public space not as spectacularly ‘pregnant men’, but as (...) fat men. As a starting point we take the experience of one participant whose heavily pregnant participation in a five-kilometer race prompted the question: ‘Why is the chubby guy running?’ Using Judith Butler's concept of the cultural intelligibility of gender, we ask why the question asked was not: ‘Why is the pregnant guy running?’ We further consider the degree to which pregnant trans people manage their unintelligibility within the matrix of pregnancy, fatness, and trans/gender and how this reveals the limits of gender intelligibility itself.

In 'The Weakness of Strong Justification' Wayne Riggs claims that the requirement that justified beliefs be truth conducive (likely to be true) is not always compatible with the requirement that they be epistemically responsible (arrived at in an epistemically responsible manner)1. He supports this claim by criticising Alvin Goldman's view that if a belief is strongly justified, it is also epistemically responsible. In light of this, Riggs recommends that we develop two independent conceptions of justification, one that (...) insists upon the requirement that beliefs be truth conducive and another that insists that they be epistemically responsible. It will then, on his view, be possible to properly evaluate beliefs with regard to each conception of justification. Riggs, however, is mistaken in supposing that the two epistemic requirements are independent. If a belief is responsibly arrived at, it is therefore likely to be true. He is thus also mistaken in supposing that the two epistemic requirements are incompatible. This mistake arises because Riggs assumes that justification is possible or, at least, that it involves standards that are akin to our own. Moreover, once this assumption is made explicit, we can see why a notion of justification that connects epistemic practice with likely truth is significant. (shrink)

Recent epistemology has reflected a growing interest in issues about the value of knowledge and the values informing epistemic appraisal. Is knowledge more valuable that merely true belief or even justified true belief? Is truth the central value informing epistemic appraisal or do other values enter the picture?

It will stimulate discussion of the nature of knowledge and of directions that might be (...) taken by the theory of knowledge.

The Credit Theory of Knowledge (CTK)—as expressed by such figures as John Greco, Wayne Riggs, and Ernest Sosa—holds that knowing that p implies deserving epistemic credit for truly believing that p . Opponents have presented three sorts of counterexamples to CTK: S might know that p without deserving credit in cases of (1) innate knowledge (Lackey, Kvanvig); (2) testimonial knowledge (Lackey); or (3) perceptual knowledge (Pritchard). The arguments of Lackey, Kvanvig and Pritchard, however, are effective only in so (...) far as one is willing to accept a set of controversial background assumptions (for instance, that innate knowledge exists or that doxastic voluntarism is wrong). In this paper I mount a fourth argument against CTK, that doesn’t rest on any such controversial premise, and therefore should convince a much wider audience. In particular, I show that in cases of extended cognition (very broadly conceived), the most salient feature explaining S ’s believing the truth regarding p may well be external to S , that is, it might be a feature of S ’s (non-human, artifactual) environment. If so, the cognitive achievement of knowing that p is not (or only marginally) creditable to S , and hence, CTK is false. (shrink)

Clare, the titular character of The Time Traveller's Wife, reflects that "Everything seems simple until you think about it." This might well be a mantra for the whole of philosophy, but a fair few terms tend to stick out. "Knowledge", "goodness" and "happiness" for example, are all pervasive everyday terms that undergo significant philosophical analysis. "Luck", I think, is another one of these terms. Wishing someone good luck in their projects, and cursing our bad luck when success seems so close (...) to our reach or failure could have so easily been otherwise, happens so often that we rarely stop to reflect on what we really mean. Philosophical reflection on the nature of luck has a rich tradition, that is by no stretch confined to the Western philosophical canon. However, it has only very recently become one of the goals of philosophy to provide a clear account of what luck actually amounts to. This, in part, is the goal of this thesis. The thesis has two primary motivations. The first is to offer and defend a general account of luck that overcomes the problems faced by the current accounts of luck that are available in the current philosophical literature. The second is to apply this general account of luck to the areas of metaethics and epistemology where luck has been a pervasive and problematic concept, and demonstrate how this account of luck may resolve or further illuminate some of the problems that the notion has generated. The thesis is roughly split into two parts. The first half of the thesis focuses on the former objective of offering an account of luck. Chapter 1 offers a selected history of the philosophy of luck that spans from the Ancient Greeks to the present day, so that we might properly situate the current work on luck as part of the broader historical importance of the concept. Chapter 2 will set out the major rival to the theory of luck that I will offer - the lack of control account of luck. LCAL has various iterations across the literature, but is most clearly articulated by Wayne Riggs and E.J. Coffman. Both Coffman and Riggs add and adapt their own conditions to LCAL specifically so that the account may overcome several problems that have been levied against it. These further conditions are not incompatible so, to provide the strongest lack of control account possible, I have combined them to form a lack of control account I have called Combined LCAL - LCAL. The latter part of the chapter pits LCAL against some of the problems that have been raised against LCAL. However, despite the efforts of both Riggs and Coffman, even LCAL fails to counter some of these objections. For these reasons I have rejected LCAL has a viable candidate for an account of luck. Chapter 3 sets out a modal account of luck, as argued for by Pritchard, where an event is lucky only if it occurs in the actual world, but not in a relevant set of nearby possible worlds. Here I further elaborate on how we should understand the modal distances using Lewisian possible world semantics, and what worlds should be taken into consideration when fixing the relevant set of nearby possible worlds. I argue that these relevant sets of worlds should be fixed according to the domain of inquiry of which the luck is being applied - this I call the type of luck. Examples of this is the current literature are resultant luck - the type of luck concerned with the results of our actions, and veritic luck - the type of luck concerned with the modal safety of our belief formation. Due to the multitude of types of luck across disciplinary areas, a general modal account of luck requires flexibility in what factors should fix the relevant sets of possible worlds. I achieve this by providing a [TYPE] function for the general modal account of luck, which is used as a mean of inserting the relevant fixing conditions for any domain of inquiry. Chapter 3, in a similar vein to Chapter 2, pits the general modal account of luck against some of the problems that have been levied against MAL, specifically the Buried Treasure problem raised by Lackey and the agent causation problem as raised by Levy. More successfully, the modal account offered stands up against these criticisms. For these reasons, the modal condition understood with the [TYPE] function and Lewisian semantics concerning modal distances, will be adopted to make up one half of the conditions for my account of luck. Chapter 4 will look at the second condition for an account of luck - the significance condition. The chapter will set out the reasons for adopting a significance condition at all, and some of the ways in which the condition has been articulated by Rescher, Pritchard and Ballantyne. All of these current views of the significance condition will be found wanting due to their inability to make sense of certain kinds of luck in specific normative domains. For example, Ballantyne's account of significance focuses on the interests of an agent, yet for certain types of moral luck, the interests of the agent are irrelevant. Instead, I propose a relativised significance condition, where the value of the event is relative to the value of the normative domain in which the luck is being ascribed. Epistemic luck requires a focus on the epistemic significance of the event for the agent, moral luck requires a focus on the moral or ethical significance of the event for the agent, and so on. This I call the kind of luck. Similar to the [TYPE] function for the modal condition for luck, the significance condition requires a [NORMATIVE DOMAIN] function where the relevant normative domain can be inserted depending on the kind of luck. This version of the significance condition will be conjoined with the modal condition as set out in Chapter 3 to form the correct general account of luck. Chapter 5 is the first chapter of the second half of the thesis that concerns applying the account of luck set out in part 1 to more specific domains of inquiry. Chapter 5 concerns moral luck, more specifically, resultant moral luck. Moral luck has traditionally been understood in terms of lack of control. This chapter looks at how Pritchard and Driver have attempted to understand moral luck using modal conditions. However, it is argued that these attempts would be more successful if we adopted the account of luck that I have offered in previous chapters. The chapter will go on to look at two possible problems that may be faced by this modal account of luck, and how it may resolve these problems. Chapter 6, the final chapter, looks at epistemic luck, specifically how the adoption of the modal account I have offered resolves a particular problem targeted at anti-luck epistemology by Ballantyne. The problem, Ballantyne argues, is that given that luck requires a significance condition, the degree of significance affects the degree of luck and that the degree of luck involved in our belief formation affects whether we are in a position to know the target proposition, that the result is that degree of significance affects our ability to know. For at least some instances of this - such as the aesthetic significance that we assign to the target proposition - the result will be that non-epistemic factors that have no relevance at all whether an agent is in a position to know will affect that agent's position to know. The resolution to this problem can be found in a two part solution. The first part is to demonstrate that any degree of veritic epistemic luck results in the agent failing to know. The second is that through the relativisation of the significance condition, any type of value will not affect an agent's position to know, only the epistemic value. With these two considerations in mind, the latter of which that can only be held through the adoption of the modal account of luck I have offered, the problem may be resolved. (shrink)

What role can intellectual virtues play in an account of knowledge when we interpret those virtues internalistically, i.e., as depending only on internal states of the cognizer? Though it has been argued that internalist virtues are ill suited to play any role in an account of knowledge, I will show that, on the contrary, internalist virtues can play an important role in recent accounts of knowledge developed to utilize externalist virtues. The virtue account of knowledge developed by Linda Zagzebski is (...) intended to be supplemented by her version of the intellectual virtues which require an external success component. John Greco and Wayne Riggs both develop credit accounts of knowledge on which the abilities we use when we get credit for a true belief must be reliable. I examine the similarities between these three accounts of knowledge and demonstrate that internalist virtues fit into these accounts just as well as externalist virtues. Thus, although internalist virtues do not require a reliable connection to truth, they can still play an important role in defining the truth-requiring concept of knowledge. (shrink)

This book argues that Kant's transcendental idealism has been misinterpreted: it denies not simply the super-sensory reality of space, time, and appearances, but their reality outside imagination as well. After adducing extensive and explicit textual evidence in its favor, Waxman shows this interpretation to be essential to the Transcendental Deduction, the affirmation of things in themselves, and the attempt to surmount Hume's scepticism. He further argues that Kant's much-neglected claim that, besides himself, "no psychologist has so much as even thought (...) that the imagination might be a necessary constituent of perception," should be construed so that even our consciousness of sensation itself (visual, tactile, etc.) is impossible without imagination. A compelling and original contribution to Kantian scholarship, Kant's Model of the Mind will also bear close examination by students and scholars of Hume, the philosophy of mind, and the philosophy of science.

How might attention intersect with normative issues and the psychology surrounding them? I provide an empirically grounded framework integrating three attentional phenomena: salience, vigilance (or broadly attunement) and attentional character. Using this frame, I review recent philosophical work on attention and norms. -/- Section 1 establishes a common ground conception of attention no more controversial than the established experimental paradigms for attention. This conception explicates the concept of a bias, which explains core features of action and attention, one that intersects (...) biological, psychological and philosophical concerns. I emphasize historical biases associated with learning and experience. Section 2 presents an analysis of automaticity and control, concepts needed to fully characterize action. Historical biases are revealed as automatic. Specifically, the automatization of attention is central to acquiring skills and excellence in light of normative standards for a practice. Section 3 argues that salience involves the deployment of attention, while Section 4 characterizes vigilance not merely as a disposition but as an active orientation to attend. Vigilance is one type of attunement, and the set of attunements constitutes the agent’s varied orientations to deploy attention, part of their attentional character. As discussed in Section 5, shaping this character is a goal of a normatively sensitive upbringing where appropriate attention is automatized through proper practice. Section 6 examines a common epistemic bias in academia and subsequent attempts to debias. I conclude with an example of acquired epistemic skill to give hope that attentional excellence is achievable. (shrink)

Reflection on the fine-grained information required for visual guidance of action has suggested that visual content is non-conceptual. I argue that in a common type of visually guided action, namely the use of manipulable artefacts, vision has conceptual content. Specifically, I show that these actions require visual attention and that concepts are involved in directing attention. In acting with artefacts, there is a way of doing it right as determined by the artefact’s conventional use. Attention must reflect our understanding of (...) the function and appropriate ways to use these artefacts, understanding that requires possession of the relevant concept. As a result, we attend to the artefact’s relevant functional properties. In these cases, attention is structured by concepts. This discussion has a bearing on the dual visual stream hypothesis. While it is often held that the two visual streams are functionally independent, the argument of this essay is that the constraints on attention suggest a functional interaction between them.

Recent work by Robert Batterman and Alexander Rueger has brought attention to cases in physics in which governing laws at the base level “break down” and singular limit relations obtain between base- and upper-level theories. As a result, they claim, these are cases with emergent upper-level properties. This paper contends that this inference—from singular limits to explanatory failure, novelty or irreducibility, and then to emergence—is mistaken. The van der Pol nonlinear oscillator is used to show that there can be a (...) full explanation of upper-level properties entirely in base-level terms even when singular limits are present. Whether upper-level properties are emergent depends not on the presence of a singular limit but rather on details of the ampliative approximation methods used. The paper suggests that focusing on explanatory deficiency at the base level is key to understanding emergence in physics. (shrink)

At my university we never stop reforming the curriculum, and we’re now discussing the plurality of ways in which our students fulfill our requirement of a full year of “freshman humanities.” Some of us feel that we now provide too many ways: neither students nor faculty members can make a good defense of a requirement—in itself an expression of power, if you will—that leads to scant sharing of readings or subject matters for the students, and to no goals or methods (...) clearly shared by increasingly diverse faculty members. As we attack and defend this kind of flabby pluralism, we naturally find ourselves discussing other kinds of pluralism, and we begin to discover the true depth of a topic that may at first seem “merely practical.” There may be some nouns that can be joined to the phrase “in the classroom” without taking on a total theory of education: Shakespeare in the classroom; Romanticism in the classroom; perhaps even irony in the classroom. But when we try to discuss “pluralism in the classroom,” we throw into the discussion every belief we may have about what education should be and how it should be conducted. To ask whether or in what sense we should be pluralists in the classroom is obviously to ask, in the most fundamental way possible, “What should a teacher teach? What should we hope that every student would learn, regardless of our commitment to this or that doctrine of the moment?”Most teachers, even in a time like ours when professed relativists pluralists abound, answer that question, at least implicitly, like this: One should try very hard to teach the truth—not a “dogma,” of course, perhaps not even a set of propositions, but at least some single right away of doing things. Indeed in some moods any honest teacher might confess to feeling lucky if students learn even one truth or one mode of working. “They’ll meet plenty of plurality just in the nature of their lives.” “They’ll meet plenty of other teachers, most of them with absolutely mistaken views, and my chief task is to set them straight so that when they encounter nonsense they’ll know how to deal with it.” Still, when you press people who talk that way they of course claim that they teach no dogmas, only an appropriately open-minded way of dealing with error in the world. They may even call themselves pluralists or relativists. But it takes no great analytical skill to detect the monisms behind their claims. When pushed, they believe that they hold=--or might someday find—some one way of working, some supremely powerful “killer mode” that can dispose of all other modes with decisive proofs. They work finally in one way only, pursuing, finally, one kind of truth. Wayne C. Booth is George M. Pullman Distinguished Service Professor of English and of Ideas and Methods at the university of Chicago. His previous works on pluralism include Critical Understanding: The Powers and Limits of Pluralism and “Pluralism and Its Rivals” in Now Don’t Try to Reason with Me .

Transposable elements (TEs) are powerful facilitators of genome evolution, and hence of phenotypic diversity as they can cause genetic changes of great magnitude and variety. TEs are ubiquitous and extremely ancient, and although harmful to some individuals, they can be very beneficial to lineages. TEs can build, sculpt, and reformat genomes by both active and passive means. Lineages with active TEs or with abundant homogeneous inactive populations of TEs that can act passively by causing ectopic recombination are potentially fecund, adaptable, (...) and taxonate readily. Conversely, taxa deficient in TEs or possessing heterogeneous populations of inactive TEs may be well adapted in their niche, but tend to prolonged stasis and may risk extinction by lacking the capacity to adapt to change, or diversify. Because of recurring intermittent waves of TE infestation, available data indicate a compatibility with punctuated equilibrium, in keeping with widely accepted interpretations of evidence from the fossil record. We propose a general and holistic synthesis on how the presence of TEs within genomes makes them flexible and dynamic, so that genomes themselves are powerful facilitators of their own evolution.
