There is a need to rapidly assess the impact of new technology initiatives on the Counter Improvised Explosive Device battle in Iraq and Afghanistan. The immediate challenge is the need for rapid decisions, and a lack of engineering test data to support the assessment. The rapid assessment methodology exploits available information to build a probabilistic model that provides an explicit executable representation of the initiative’s likely impact. The model is used to provide a consistent, explicit, explanation to decision makers on (...) the likely impact of the initiative. Sensitivity analysis on the model provides analytic information to support development of informative test plans. (shrink)

This expands the proposal in 'Is consciousness only a property of individual cells?' to attempt to cover all relevant psychological, neuroscientific and philosophical issues. Some of the material is now dated (in 2011) but chiefly in the sense that tentative proposals have become firmer views for me. An example of this is the clarification of complementarities in "Are our spaces made of words?'.

This book offers both the theoretical background behind the minority effect, teachers' personal experiences as they experienced being a minority, and their analyses and insights for teaching diverse learners. This book uses real-life experiences of diverse people to illustrate that, if not understood and addressed, situational minorities at school or work are unlikely to perform at their highest potentials.

Understanding what numbers are means knowing several things. It means knowing how counting relates to numbers (called the cardinal principle or cardinality); it means knowing that each number is generated by adding one to the previous number (called the successor function or succession), and it means knowing that all and only sets whose members can be placed in one-to-one correspondence have the same number of items (called exact equality or equinumerosity). A previous study (Sarnecka & Carey, 2008) linked children's understanding (...) of cardinality to their understanding of succession for the numbers five and six. This study investigates the link between cardinality and equinumerosity for these numbers, finding that children either understand both cardinality and equinumerosity or they understand neither. This suggests that cardinality and equinumerosity (along with succession) are interrelated facets of the concepts five and six, the acquisition of which is an important conceptual achievement of early childhood.

: Seyla Benhabib's critique of Jürgen Habermas's moral theory claims that his approach is not adequate for the needs of a feminist moral theory. I argue that her analysis is mistaken. I also show that Habermas's moral theory, properly understood, satisfies many of the conditions identified by feminist moral philosophers as necessary for an adequate moral theory. A discussion of the compatibility between the model of reciprocal perspective taking found in Habermas's moral theory and that found in María Lugones's essay (...) "Playfulness, 'World'-Travelling, and Loving Perception" reinforces the claim that his moral theory holds as yet unrecognized promise for feminist moral philosophy. (shrink)

Three issues related to Feldman and Levin's treatment of biological variability are discussed. We question the usefulness of the indirect component of δλ. We suggest that trade-offs between speed and accuracy in aimed movements support identification of δλ, rather than λ, as a control variable. We take issue with the authors' proposal for resolving redundancy in multi-joint movements, given recent data.

The assessment of student learning is widely regarded with suspicion. Philosophers in particular have been reluctant to take this practice seriously. The essay reviews an ongoing effort to assess the development of philosophical dispositions among undergraduate students at a religiously affiliated liberal arts college. The procedure used in this effort as well as the results obtained so far strongly suggest that the deep learning valued most highly by philosophy teachers can be measured without harm to the teaching enterprise. The essay (...) argues that in light of a current cultural climate that fails to recognize the value of our enterprise, philosophers would be well advised to clearly define our particular learning goals, develop our own instruments, and to exercise more initiative in assessing our students learning.

Evolutionary biologists have suggested that human moral judgment is best understood as an emotionally mediated phenomenon. With few exceptions, philosophers have scorned these proposals. Recent research in moral psychology and social neuroscience indicates, though, that moral judgment is produced by the coordinated activity of multiple regions of the brain, and consists of both cognitive and affective processes. Evidence also suggests that different dimensions of moral judgment – the affective and cognitive processes, for instance – possess distinct evolutionary histories. Moral philosophers (...) will need to reconsider longstanding debates – such as those between Humeans and anti-Humeans, and between motivation internalists and externalists – in light of this evidence. Otherwise we run the risk of disciplinary irrelevance. (shrink)

We report data from an experiment using stimuli designed to differ in their availability for processing by the dorsal visual pathway, but which were equivalent in tasks mediated by the ventral pathway. When movements are made to these stimuli as targets, there are clear effects early in the movement. These effects appear at odds with the planning–control model of Glover.

Although it provides a useful description of elementary movement trajectories, we argue that the delta-lognormal model is deficient as an account of speed/accuracy tradeoffs in aimed movements. It fails in this regard because (1) it is deterministic, (2) its formulation ignores critical task elements, and (3) it fails to account for the corrective role of submovements.

The essays in this book weave together insights and arguments from such diverse traditions as German critical theory, French philosophy and social theory, and recent Anglo-American moral and political theory, offering a unique approach to the political and theoretical consequences of the modernism/postmodernism discussion. Through an analysis of central themes in classical Marxism and early critical theory, the author shows how recent work in a variety of traditions converges on the need to question familiar distinctions between material production and culture, (...) the public and the private, and the political and the social, and to reconsider the conceptions of agency and power that have informed them.

One of the dominating themes in the first part is the negative treatment that Marx’s concept of labor has received by late critical theorists, particularly Habermas. While supportive of the rejection of Marx’s economic functionalism entailed by Habermas’s adoption of communicative action as the basic category of critical theory, Honneth worries about the indifference towards the normative potential of labor that he sees in most twentieth-century social theory. Honneth agrees with critics of reductionism that labor is neither the only form (...) of social reproduction, nor a primary source of emancipatory consciousness, as the fragmentation and depolitization of a working class that has suffered the effects of Taylorism clearly manifests. But Honneth is still convinced that the experience of recognition is to a large extent associated with work, and that Habermas tends to understand interaction in terms of instrumental action, making the concept of interaction inadequate to capture the sort of normative claims expressed by workers who do not see themselves sufficiently recognized in the labor they do. Although Honneth acknowledges that he has not settled how to navigate between these competing interests, the clarity of the call for a more complex concept of labor justifies the inclusion of these papers in the volume.

No consensus yet exists on how to handle incidental fnd-ings in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are fndings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers (...) have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed. (shrink)

Nihilism, Nietzsche and the Doppelganger Problem Was Nietzsche a nihilist? Yes, because, like J. L. Mackie, he was an error-theorist about morality, including the elitist morality to which he himself subscribed. But he was variously a diagnostician, an opponent and a survivor of certain other kinds of nihilism. Schacht argues that Nietzsche cannot have been an error theorist, since meta-ethical nihilism is inconsistent with the moral commitment that Nietzsche displayed. Schacht’s exegetical argument parallels the substantive argument (advocated in recent years (...) by Wright and Blackburn) that Mackie’s error theory can’t be true because if it were, we would have to give up morality or give up moralizing. I answer this argument with a little bit of help from Nietzsche. I then pose a problem, the Doppelganger Problem, for the meta-ethical nihilism that I attribute to Mackie and Nietzsche. (If A is a moral proposition then not-A is a moral proposition: hence not all moral propositions can be false.) I solve the problem by reformulating the error theory and also deal with a variant of the problem, the Reinforced Doppelganger, glancing at a famous paper of Ronald Dworkin’s. Thus, whatever its demerits, the error theory, is not self-refuting, nor does it require us to give up morality. (shrink)

Work throughout the history and philosophy of biology frequently employs ‘chance’, ‘unpredictability’, ‘probability’, and many similar terms. One common way of understanding how these concepts were introduced in evolution focuses on two central issues: the first use of statistical methods in evolution (Galton), and the first use of the concept of “objective chance” in evolution (Wright). I argue that while this approach has merit, it fails to fully capture interesting philosophical reflections on the role of chance expounded by two (...) of Galton's students, Karl Pearson and W.F.R. Weldon. Considering a question more familiar from contemporary philosophy of biology—the relationship between our statistical theories of evolution and the processes in the world those theories describe—is, I claim, a more fruitful way to approach both these two historical actors and the broader development of chance in evolution.

We argue that the economy of nature constitutes an invocation of structure in the biological sciences, one largely missed by philosophers of biology despite the turn in recent years toward structural explanations throughout the philosophy of science. We trace a portion of the history of this concept, beginning with the theologically and economically grounded work of Linnaeus, moving through Darwin’s adaptation of the economy of nature and its reconstitution in genetic terms during the first decades of the Modern Synthesis. What (...) this historical case study reveals, we argue, is a window into the shifting landscape of the explanatory and ontic uses of structural concepts. In Linnaeus, the economy of nature has both ontic and explanatory import; in Darwin the ontic and explanatory aspects start to come apart ; and finally, in the Modern Synthesis, the economy of nature is replaced by the conceptual toolkit of population genetics, the structural elements of which are nearly entirely explanatory. Having traced a historical trajectory of structural concepts that moves from an ontic formulation to an increasingly explanatory one, we conclude by outlining some insights for structural realism.

In his book Wittgenstein on the Foundations of Mathematics, Crispin Wright notes that remarkably little has been done to provide an unpictorial, substantial account of what mathematical platonism comes to. Wright proposes to investigate whether there is not some more substantial doctrine than the familiar images underpinning the platonist view. He begins with the suggestion that the essential platonist claim is that mathematical truth is objective. Although he does not demarcate them as such, Wright proposes several different (...) tests for objectivity. The paper finds problems with each of these tests. (shrink)

This paper develops and draws the consequences of an etiological analysis of goal-directedness modeled on one that functions centrally in Charles Taylor's work on action. The author first presents, criticizes, and modifies Taylor's formulation, and then shows his modified formulation accounts easily for much of the fine-structure of teleological concepts and conceptualizations. Throughout, the author is at pains to show that teleological explanations are orthodox from an empiricist's point of view: they require nothing novel methodologically.

the theory of modal groups is an abstract theory that may be used to show formal similarities between various formulations of epistemic logics (eg Hintikka, Chisholm, and von Wright) and formal systems in other domains.

The United States Supreme Court's decision in Bell Atlantic Corp. v. Twombly is creating quite a stir. Suddenly gone is the famous loosey-goosey rule of Conley v. Gibson that a complaint should not be dismissed for failure to state a claim unless it appears beyond doubt that the plaintiff can prove no set of facts in support of his claim which would entitle him to relief.Now a complaint must provide enough facts to state a claim to relief that is plausible (...) on its face. Only decided last May, Bell Atlantic has been cited in over 3,700 cases. Already being described as a landmark decision, Bell Atlantic nonetheless has lawyers and judges scratching their heads over the precise pleading standard to apply in its wake. As the Second Circuit (mildly) put it, Considerable uncertainty concerning the standard for assessing the adequacy of pleadings has recently been created by the Supreme Court's decision in Bell Atlantic Corp. v. Twombly. Just what is a plausible showing that the pleader is entitled to relief under Rule 8(a)(2)?I believe an answer lies in the 26-year-old decision of the Former Fifth Circuit in In re Plywood Antitrust Litigation. Plywood Antitrust requires, at a minimum, that a complaint . . . contain either direct or inferential allegations respecting all the material elements necessary to sustain a recovery under some viable legal theory. Already used in more than half the circuits, this standard paraphrases advice found in the venerable WRIGHT & MILLER for nearly 40 years.Properly applied, this all . . . material elements standard satisfies Bell Atlantic's plausibility requirement in all respects. The Plywood Antitrust pleading standard works well after Bell Atlantic, first, because the Supreme Court referred to the standard, albeit parenthetically, with approval in Bell Atlantic. Second, it does much to harmonize the Federal Rules' goal of dispensing with pleading technicalities while still requiring enough general factual information about a pleader's claim to make the notice in notice pleading meaningful. Finally, and perhaps most importantly, it gives lawyers, litigants, and courts a standard they can actually use when drafting, or assessing the sufficiency of, pleadings. (shrink)

I examine an argument proposed by Tye and Wright, inspired by Geach, which holds that a correct understanding of how conceptual thought occurs in time demands we expel it from experience. This would imply—pace William James— that the “stream of consciousness” is not, even in part, a “stream of thought.” I argue that if we closely examine what seems to support crucial premises of their argument, we will find this undermines its other assumptions, and points us to a way (...) of placing thought in time that they neglect. Ultimately, attention to the phenomenology of language comprehension and production not only undercuts their “temporality argument” against including thought in experience; it prepares the ground for a case in favor of inclusion. In critiquing their argument I hope not just to disarm an objection to a view I espouse, nor even just to discover new support for it, but also to shed some light on the temporality of thought and its relation to self-expression.

In presenting this paper for the Festschrift in honor of my long time friend, Charles Hartshorne, I should state at once that I am writing as a biologist, specifically a geneticist, interested in the philosophical implications of his subject, but with only a superficial knowledge of philosophy in general. My justification for writing on this topic is the belief that the philosophy of science is necessarily a joint venture since it is obvious that advances in science provide data on (...) the nature of existence which must be taken into account in philosophical consideration of this subject. This is most obvious in connection with the drastic revision of the basic concepts of physics since 1900, the impact of which on philosophy has recently been brilliantly developed by Čapek. There have also been great advances in biology. The resulting concepts do not strike at the very categories of thought and defy expression in language as do those of modern physics. Nevertheless they have a special importance from the facts that the only direct knowledge of mind that any one possesses is associated with a certain living organism, himself, and that in general, indications of the presence of mind are restricted to living organisms. The fact that while such indications are universally accepted in the case of other human beings but become progressively less convincing as we pass to animals closely similar to man, and from these to such forms as fishes, insects, clams, worms and protozoa, raises difficulties. Few see any indication of mind in plants. (shrink)
