Open peer commentary on the article “Constructivist Model Building: Empirical Examples From Mathematics Education” by Catherine Ulrich, Erik S. Tillema, Amy J. Hackenberg & Anderson Norton. Upshot: I look at the different possibilities offered by the trajectory of second-order models in mathematics education. It seems to me that although possibilities are extended as models become more elaborate, this is only the case if teacher/researchers remain cognisant of a radical constructivist perspective. I also suggest that broad-ranging research on the models affords (...) insight into the “big” mathematical ideas to which all students should have access. (shrink)

This article attempts to respond to Simon Critchley's claim in a recent debate with Richard Rorty, that the latter, by not fully recognizing its indebtedness to Levinas, misunderstands the political import of the work of Jacques Derrida. I maintain, pace Critchley, that trying to push the Derrida–Levinas connection too far will not only further compound Rorty's view of Derrida as a thinker devoid of political efficacy, but that it will moreover serve to obscure the significant differences which exist between Levinas (...) and Derrida – differences which cannot be overlooked in any serious discussion of the two thinkers in question. In the second half, I try to convince Critchley that what separates Derrida from Levinas is precisely what hooks him up with Rorty at a political level. Both, I argue, are committed to a civic religion of social hope. In so doing, I try to convince Rorty that his caricature of Derrida as a private writer without political consequence, ought now to be seriously reconsidered. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Veritas Filia Temporis: Experience and Belief in Early Modern Culture *Brendan DooleyFew observers in the seventeenth century had any illusions about the reliability of political information imparted by the sources newly minted or voluminously increased during the course of the century. The newsletters appeared to be concocted from malicious gossip. 1The newspapers seemed to be published at the bidding of powerful political interests with little inclination to tell the (...) truth, 2and histories of recent events seemed to be based on faulty sources even when the writers endeavored to procure faithful accounts. “Truth is by nature elusive and slippery,” history theorist Agostino Mascardi admitted. All he could recommend as a defense for the inaccurate historian was the injunction against throwing the first stone: “Omnis homo mendax,” said David the holy king; and those who are such harsh critics of historians’ involuntary lies may well be astute trammelers of perfidy and deceit in their own lives.” 3He had no answer about historians who deliberately distorted the truth. In fact just when readers might have desired it most, from the earliest episodes of the Thirty-Years War to the last episodes of the Turkish Wars at the end of the century, the possibility of [End Page 487]gaining a realistic picture of the contemporary world seemed to be getting more and more remote.The argument of this article centers around a discussion of the cultural consequences of this late seventeenth-century trend. To some of the readers, writers, thinkers, and theorists in this period, the unreliability of information about their own time or about the past, however compounded by contemporary political and social circumstances, was nothing but a minor nuisance. To others it was a hint about the bad faith of the governments who influenced writers. To still others, this same unreliability raised deeply troubling questions about human nature and existence. It provided social and political reasons for historical skepticism, quite apart from one’s familiarity with Sextus Empiricus or the elite intellectual trends of the time. It placed everyday social and political reality in a new light, thus adding a more mundane element to the uneasy feeling produced by the new science and cosmology—the feeling, that is, of being borne along in uncontrollable currents whose exact nature the best minds nonetheless seemed incapable of understanding. It added to the disquiet produced by confessional disputes, suggesting that truth might be beyond human capacity to grasp. 4Not only in Italy but throughout Europe in the late seventeenth century this discussion will show, existing methods of ascertaining facts in political and military affairs both in the present and in past times came under a new sort of scrutiny as part of what some scholarship has regarded as no less than a wide-ranging “crisis of consciousness” at the threshold of the Enlightenment. 5The conclusion opens briefly onto the sequel of these episodes. The crisis was resolved at least in part by a corresponding movement for methodological change as well as by a reform of ideas about the proper place for intellectual improvisation in the formation of narrative in order to make historical writing persuasive as well as civically useful again. If the product of error and fraud was skepticism, the product of skepticism was modern historiography. 6 [End Page 488]History and ExperienceObviously, the elusiveness of political truth that helped touch off the late seventeenth-century crisis was no novelty of the age. Deliberate misinformation was a fully-recognized political strategy at least by the time that Machiavelli made it an explicit part of prudence by recommending the cultivation of good appearances and expressing his admiration for Pope Alexander VI and Ferdinand I of Spain as being the best liars of their time. 7In the late sixteenth century theorists all over Europe sought to join Machiavelli’s insights about the inner workings of state power to those of Tacitus in the light of conventional morality. 8In Italy it was the Piedmontese writer Giovanni Botero who, exploring these Tacitist perspectives in his Reason of State, expressed the fewest reservations about insisting on the propriety of a policy of state secrecy and misinformation. 9Florentine political theorist...

If a utopia is a near perfect, or even a demonstrably superior, society, is there anything that endangers that society as soon as it is achieved? Yes. Prosperity! I have shown in “More's Utopia and the New World Utopias: Is the Good Life an Easy Life?”, that the actually existing, “real” New World Utopian communities were severely challenged by success. For example, the vigor of the Jansonite community in Bishop Hill, Illinois (1846-1860) sharply declined when that community met their survival (...) needs and had to deal with surpluses and comfort. As soon as communal efforts and group sacrifices produced prosperity, the attractiveness of communism faded. (shrink)

In this book, T. L. Short places the notorious difficulties of Peirce's important writings in a more productive light, arguing that he wrote philosophy as a scientist, by framing conjectures intended to be refined or superseded in the inquiries they initiate. He argues also that Peirce held that the methods and metaphysics of modern science are amended as inquiry progresses, making metaphysics a branch of empirical knowledge. Additionally, Short shows that Peirce's scientific work expanded empiricism on empirical grounds, grounding his (...) phenomenology and subverting the fact/value dichotomy, and that he understood statistical explanations in nineteenth-century science as reintroducing the idea of final causation, now made empirical. Those innovations underlie Peirce's late ideas of a normative science and of philosophy as a branch of science. Short's rich and original study shows us how to read Peirce's writings and why they are worth reading. (shrink)

As social media becomes increasingly popular, human subjects researchers are able to use these platforms to locate, track, and communicate with study participants, thereby increasing participant retention and the generalizability and validity of research. The use of social media; however, raises novel ethical and regulatory issues that have received limited attention in the literature and federal regulations. We review research ethics and regulations and outline the implications for maintaining participant privacy, respecting participant autonomy, and promoting researcher transparency when using social (...) media to locate and track participants. We offer a rubric that can be used in future studies to determine ethical and regulation-consistent use of social media platforms and illustrate the rubric using our study team’s experience with Facebook. We also offer recommendations for both researchers and institutional review boards that emphasize the importance of well-described procedures for social media use as... (shrink)

In 15 insightful essays, Jacques Derrida and an international group of scholars of religion explore postmodern thinking about God and consider the nature of forgiveness in relation to the paradoxes of the gift. Among the themes addressed by contributors are the possibilities of imagining God as unthinkable, imagining God as non-patriarchal, imagining a return to Augustine, and imagining an age in which praise is far more important than narrative. Questioning God moves readers beyond the parameters of metaphysical reason and modernist (...) rationality as it attempts to think the questions of God and forgiveness in a postmodernist context. Contributors include John D. Caputo, Jacques Derrida, Mark Dooley, Francis Schüssler Fiorenza, Robert Gibbs, Jean Greisch, Kevin Hart, Richard Kearney, Cleo McNelly Kearns, John Milbank, Regina M. Schwartz, Michael J. Scanlon, and Graham Ward. Indiana Series in the Philosophy of Religion—Merold Westphal, general editor. (shrink)

Graduate and undergraduate students were asked to evaluate the ethicality and practicality of the lead character in several case scenarios. Students' responses indicated they believed practicality was more important than ethicality. The majority of students were able to determine the correct ethicality of the cases presented to them. The authors conclude that more research is needed in the antecedents of a student's value system.

Summary A number of elite boys? schools in England have admitted girls for over 30 years, some thereby becoming mixed schools. In other schools, girls remain a very small minority. This paper focuses upon prospectuses from the latter type of school, arguing that prospectuses are particularly valuable as a basis for judging schools? policies and practices in their own terms. The researchers ask questions about the nature of this form of ?co-education?, particularly as it affects girls? educational and social opportunities. (...) On balance, the prospectuses paint a picture of boys? schools which happen to have girls in them rather than of schools whose policies and practices have become genuinely co-educational. (shrink)

Can God create an unliftable stone? Beall & Cotnoir propose that ‘God can create an unliftable stone’ is a truth-value gap (neither true nor false). However, this yields a revenge paradox on whether God can eschew gaps. Can God avoid gappy ascriptions of power? Either way, God’s power seems to have limits. In response, it may be said that ascribing God the power to avoid gaps is itself gappy—it concerns a power that God neither has nor lacks. Yet this ends (...) up being inconsistent, for it implies that God definitely lacks that power. Following Aquinas, perhaps Beall & Cotnoir could accept this lack and still uphold omnipotence, suggesting that the power to avoid gaps is impossible for God. Yet the Aquinian stratagem is enough to block the original paradox, which saps the motivation to proffer truth-value gaps in addition. I conclude that the gappy solution is either inadequate or insufficiently motivated. (shrink)

In this paper a close look is taken at van Fraassen's use of the concept of truth. It is shown that the rather deflationist understanding of the term in his more recent publications differs considerably from the one referred to in his earlier writings, where the truth of a scientific theory is construed as its correspondence to the world. As will be argued, his more recent remarks call for a reevaluation of the difference between scientific realism and constructive empiricism and (...) force him - for the sake of consistency - to give up his realist commitments regarding the world and the observable.

This paper begins with a problem stemming from Hume regarding credences about credences. Suppose one has a credence of .95 in p, and suppose one assesses the credence to be such. But suppose one’s second-order credence in this assessment is less than 1. Then, by a standard conditionalization rule, one’s credence in p becomes less than .95. Moreover, such “erosion” can iterate by considering one’s, third-, fourth-, fifth-order credences, etc. (In light of this, some have rejected higher-order credences; however, it (...) is argued that Lewis’ “Principal Principle” forbids this.) The paper then offers a partial solution by describing circumstances under which a person has reason to assign credence 1 to a first-order credence. The solution takes the form of a “transparency” view of self-knowledge from Parent (2017, chapter 8). Briefly, it is argued that when one “reflex-like” utters a sentence “The probability of p is n”, then as a matter of psychological law, the utterance is an expression of one’s own judgment. The Principal Principle then necessitates that one’s credence in p is n, assuming one is being rational. Thus, upon perceiving such an utterance, one can thereby have a reason to assign a second-order credence of 1. (shrink)

"Aristotle was a systematic writer who often cross-referred to the definitions of terms given elsewhere in his work. Book 5 of the Metaphysics is important because it consists of definitions of the main uses of key terms in Aristotle's philosophy, and it is extremely valuable to have a commentary on this important text by Alexander of Aphrodisias, the leading commentator of his school. Alexander provides a detailed commentary on all of the thirty terms analysed in Book 5, weighing alternative interpretations (...) of what Aristotle says one against another, defending Peripatetic views against actual and possible criticisms, and attempting to integrate what is said in Book 5 into the context of the Metaphysics as a whole."--Bloomsbury Publishing.

Questioning Ethics is a major discussion by some of world's leading thinkers of some of the most important ethical issues confronting us today. New essays including Habermas, MacIntyre, Ricoeur and Kristeva discuss issues such as the nature of politics, women's rights, lying, repressed memory, historical debt and forgiveness, the self and responsibility, revisionism, bioethics and multiculturalism. The contributors organize their discussions along the topics of hermeneutics, deconstruction, critical theory, psychoanalysi and the applications of ethics. Also included in this collection is (...) an interview with Jacques Derrida which provides the most accessible insight into his thinking. Contributors: Karl-Otto Apel, Geoffrey Barash, John Caputo, Maeve Cooke, Simon Critchley, Jacques Derrida, Simon Glendinning, Jean Greish, Jurgen Habermas, Richard Kearney, Peter Kemp, Julia Kristeva, Alasdair MacIntyre, Thomas McCarthy, David Rasmussen, William J.

Two key questions in the autophagy field are the mechanisms that underlie the signals for autophagy initiation and the source of membrane for expansion of the nascent membrane, the phagophore. In this review, we discuss recent findings highlighting the role of the classical endosomal pathway, from plasma membrane to lysosome, in the formation and expansion of the phagophore and subsequent degradation of the autophagosome contents. We also highlight the striking conservation of regulatory factors between the two pathways, including those regulating (...) membrane budding and fusion, and the role of the lysosome in sensing the nutrient status of the cell, regulating mTORC1 activity, and ultimately the initiation of autophagy.Editor's suggested further reading in BioEssays The evolution of dynamin to regulate clathrin‐mediated endocytosis Abstract.
