Deep neural networks (DNNs) have had extraordinary successes in classifying photographic images of objects and are often described as the best models of biological vision. This conclusion is largely based on three sets of findings: (1) DNNs are more accurate than any other model in classifying images taken from various datasets, (2) DNNs do the best job in predicting the pattern of human errors in classifying objects taken from various behavioral datasets, and (3) DNNs do the best job in predicting (...) brain signals in response to images taken from various brain datasets (e.g., single cell responses or fMRI data). However, these behavioral and brain datasets do not test hypotheses regarding what features are contributing to good predictions and we show that the predictions may be mediated by DNNs that share little overlap with biological vision. More problematically, we show that DNNs account for almost no results from psychological research. This contradicts the common claim that DNNs are good, let alone the best, models of human object recognition. We argue that theorists interested in developing biologically plausible models of human vision need to direct their attention to explaining psychological findings. More generally, theorists need to build models that explain the results of experiments that manipulate independent variables designed to test hypotheses rather than compete on making the best predictions. We conclude by briefly summarizing various promising modeling approaches that focus on psychological data. (shrink)

Vector-based models of word meaning have become increasingly popular in cognitive science. The appeal of these models lies in their ability to represent meaning simply by using distributional information under the assumption that words occurring within similar contexts are semantically similar. Despite their widespread use, vector-based models are typically directed at representing words in isolation, and methods for constructing representations for phrases or sentences have received little attention in the literature. This is in marked contrast to experimental evidence (e.g., in (...) sentential priming) suggesting that semantic similarity is more complex than simply a relation between isolated words. This article proposes a framework for representing the meaning of word combinations in vector space. Central to our approach is vector composition, which we operationalize in terms of additive and multiplicative functions. Under this framework, we introduce a wide range of composition models that we evaluate empirically on a phrase similarity task. (shrink)

This article argues that the freedom of voluntary action can be grounded in the contingency of the laws of nature. That is, the possibility of doing otherwise is equivalent to the possibility of the laws being otherwise. This equivalence can be understood in terms of an agent drawing a boundary between self and not-self in the domains of both matter and laws, defining the extent of the body and of voluntary behaviour. In particular, the article proposes that we can think (...) of ‘will’ as naming the component of the laws of nature delimited by this boundary. (shrink)

The article features an analytic protocol for examining controversial criminal cases in critical thinking courses. The rubric has been designed to be useful to busy critical thinking teachers who wish to draw on student interest in true crime. Six guidelines are presented that are intended to provide the instructor with a convenient scheme for quickly and easily framing classroom discussions. Due to their generality, the guidelines can be readily applied to a wide-range of cases, giving educators a high degree of (...) flexibility in the selection of criminal affairs. (shrink)

On several key issues we agree with the commentators. Perhaps most importantly, everyone seems to agree that psychology has an important role to play in building better models of human vision, and (most) everyone agrees (including us) that deep neural networks (DNNs) will play an important role in modelling human vision going forward. But there are also disagreements about what models are for, how DNN–human correspondences should be evaluated, the value of alternative modelling approaches, and impact of marketing hype in (...) the literature. In our view, these latter issues are contributing to many unjustified claims regarding DNN–human correspondences in vision and other domains of cognition. We explore all these issues in this response. (shrink)

In the essay I argue that the routine use of contraception is morally tantamount to early-term abortion because it produces the same result: namely, it prevents the creation of a human life that would have otherwise probably taken place. Because it can be shown that contraception is ethically acceptable, it follows that early-term abortion is as well.

John Dewey’s Ethics, which he co-authored with James Hayden Tufts, is now available as an online text in the public domain. Indeed, unrestricted access copies are obtainable on the Internet for both editions of the Ethics: the first edition of 1908 and the much revised second edition of 1932. This should be welcome news for teachers, because the book represents a cornucopian instructional resource. The Ethics constitutes an ambitious and comprehensive work that is organized into three distinct parts, which respectively (...) treat the historical and cultural background of Western mores, the main currents of Western moral theory, and the ethical aspects of several modern social problems. Given the text’s wide sweep... (shrink)

In philosophy textbooks for undergraduates the cultural anthropologist Ruth Benedict is often cited as a proponent of moral relativism, and her writings are not infrequently excerpted to illustrate the view that the individual’s moral values are culturally determined. Because Benedict established that significant differences can exist in the underlying cultural patterns of different societies, her work is commonly construed as providing evidence for the arbitrary and non-rational basis of morals. The author of the present essay argues that this popular reading (...) of Benedict is mistaken. He draws a distinction between two different forms of moral relativism—the objective and the subjective—and then contends that Benedict is widely viewed as a subjective relativist when in fact her relativism was of the objective variety. He shows that her position actually has much in common with the pragmatic meliorism of John Dewey and George Herbert Mead. (shrink)

This innovative book proposes that what we think of as “moral conscience” is essentially the exercise of reflective judgment on the goods and ends arising in interpersonal relations, and that such judgment constitutes a form of taste. Through an historical survey Mitchell shows that the constant pendant to taste was an educational and cultural ideal, namely, that of the gentleman, whether he was an ancient Greek citizen-soldier, Roman magistrate, Confucian scholar-bureaucrat, Renaissance courtier, or Victorian grandee. Mitchell argues that it was (...) neither an ethical doctrine nor methodology that provided the high cultures with moral and political leadership, but rather an elite social order. While the gentry in the traditional sense no longer exists, it nevertheless made significant historical contributions, and insofar as we are concerned to understand the present state of human affairs, we need to grasp the nature and import of said contributions.

The distinction between weak and strong forms of critical thinking is a hallmark of Richard Paul’s pedagogy. He maintains that good reasoning entails a personal commitment to fair-mindedness. In this brief essay, I argue that Paul’s conception of fair-mindedness conflates cognitive empathy with empathetic concern and altruism. One’s understanding another’s perspective by no means entails approving of it, and one may seek to better grasp this standpoint for purely selfish reasons. Depending upon the circumstances, the other could be one’s competitor, (...) enemy, mark, or even intended victim. This implies that while we may wish that the world were otherwise, even very bad people can be highly effective critical thinkers. (shrink)

Are the French really ? Jeff Mitchell investigates what motivates such U.S. anti-French sentiments.

In this paper I give an account of self-deception by situating it within the theory of human conduct advanced by American pragmatists John Dewey and George Herbert Mead. After examining and rejecting the two most prevalent explanations of self-deception - namely, Sigmund Freud's psychoanalytic interpretation and Jean-Paul Sartre's phenomenological one - I provide a brief sketch of some of Dewey's and Mead's fundamental insights into the inherently social nature of mind.I argue that one of the main forms of self-deception involves (...) unreflective acceptance of a belief that impartial inspection would readily expose as spurious. In this instance lying to oneself arises from the failure to analyze an appealing idea from the perspective of the generalized other which we acquire through participation in the universe of rational discourse. I conclude by pointing to certain features of contemporary social life that may indirectly promote such self-dissimulation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Nietzsche’s Case: Philosophy as/and LiteratureJeff MitchellNietzsche’s Case: Philosophy as/and Literature, by Bernd Magnus, Jean-Pierre Mileur and Stanley Stewart; 284 pp. New York: Routledge, Chapman & Hall, 1993, $16.95.In their “Pre(post)faces,” which open and conclude Nietzsche’s Case, the authors explain that the essay was primarily motivated by a problem they perceived in English-speaking Nietzsche criticism. Critical discussion of Nietzsche has suffered, they argue, from institutionalized “mutual shunning” which creates (...) a neat divide between literary and philosophical discourses. From within the safety of their professional keep, philosophers have generally adjudged literary treatments of Nietzsche’s writings negatively, assigning them a place on a scale ranging from “inaccurate” to “inept.” Viewed from the walls surrounding the literary stronghold, philosophical analyzes of Nietzsche have appeared naive and/or uninteresting. The authors assert that especially in the case of Nietzsche this turf mentality in the humanities has impoverished our cultural imagination, since he presents us with a sort of writing which defies mutually exclusive pigeon-holing as either philosophical or literary.Philosophy, the authors maintain, arises “out of the possibilities of idealization” (p. 138). Literary criticism, on the other hand, is “based on the possibilities of textualization” (p. 138). Philosophers studying Nietzsche tend to look for coherent meaning and, even more importantly, for logical rigor, whereas literary critics generally read “for novel new ideas, new insights, for fractures, fissures, and ambiguities in Nietzsche’s texts, for opportunities or connections missed” (p. 4). Nietzsche’s Case is an experiment in genre-mixing, [End Page 164] incorporating as it does all of these concerns into its critical perspective. The authors argue that Nietzsche’s work demands such criticism since his texts are informed by a conceptual rigor whose logic involves exploitation of the literary and rhetorical possibilities of the written word.The book’s project—undertaken, appropriately enough, by a philosopher (Magnus) and two literary theorists (Mileur and Stewart)—sets out to establish a new mode of criticism by carefully tracing the ways in which Nietzsche’s texts exceed traditional boundaries. The book’s extended argument aims at showing that Nietzsche’s transgression of hoary epistemic borders was directly motivated by his own genealogy of Western knowledge. “I, Plato, am the truth”—Nietzsche’s quip from the Twilight of the Idols ironically exposes the philosophical will to truth, and it is this claim to be primarily concerned with truth that the authors say can be seen “with only slight exaggeration,” as “the founding gesture of philosophy as it has been delivered over to us” (p. 4). They helpfully recall that part of Nietzsche’s genealogy which traces the origins of philosophy to religion and the priestly caste. Claims to the possession of knowledge were tied very early on to priestly strategies of asceticism and social domination, which cleverly highlighted the salvational nature of “true” knowledge as well as the discipline and self-renunciation required to attain it. On Nietzsche’s analysis, the dedication of philosophers to truth for truth’s sake and the supposedly disinterested character of their ideas and observations are the descendants of priestly asceticism.Magnus, Mileur and Stewart suggest that the philosophers’ assumption of a wholly objective and definitive access to truth was a pipedream, and that it helped seduce philosophers into a blindness vis-à-vis the interested and personal nature of their own theories, the textuality of their interpretations of world and humankind. If one grants this thesis, then the self-evident contemporary division between philosophy and literary criticism becomes, effectively, much less self-evident.The book’s originality and strength comes out best in the detailed analyses to which the authors’ new critical mode gives rise. In addition to displaying an impressive command of the enormous secondary literature on Nietzsche, the research team draws a series of novel and interesting comparisons between Nietzsche’s texts and texts from the English Renaissance and Romantic periods. Their emphasis on understanding the rhetorical aspects of Nietzsche’s writing—such as his continual use of hyperbole—should prove to be a genuine resource in interpreting his writings in the future. By pointing out and investigating the various rhetorical devices Nietzsche employs, they... (shrink)
