Every perceptual experience has an objective and a subjective side. We see object size, independent of distance, but we also see that distant objects project smaller images. Early modern conceptions focused on local stimulation and thus on the subjective aspect. Helmholtz and Hering emphasized the objective aspect. Helmholtz split visual experience into two stages, with sensation representing the subjective side and perception, through cognitive processes, the objective side. Gestalt theory denied this dualism, rejecting both sensory and cognitive stages. Despite contrary (...) evidence, the sensation/perception dualism persists, in brightness models and past experience theories. That we can detect visual angle and luminance does not mean that these are raw sensations out of which perception of size and lightness is built. Size and color constancy are truly visual, not cognitive. Instructions to subjects in vision experiments must avoid the proximal mode on the one hand and cognitive judgments on the other. (shrink)

Psychophysical scaling models of the form R = f, with R the response and I some intensity of an attribute, all assume that people judge the amounts of an attribute. With simple biases excepted, most also assume that judgments are independent of space, time, and features of the situation other than the one being judged. Many data support these ideas: Magnitude estimations of brightness increase with luminance. Nevertheless, I argue that the general model is wrong. The stabilized retinal image (...) literature shows that nothing is seen if light does not change over time. The classification literature shows that dimensions often combine to produce emergent properties that cannot be described by the elements in the stimulus. These and other effects cannot be adjusted for by simply adding variables to the general model because some factors do not combine linearly. The proposed alternative is that people initially judge the entire stimulus – the object in terms of its environment. This agrees with the constancy literature that shows that objects and their attributes are identified through their relations to other aspects of the scene. That the environment determines judgments is masked in scaling studies where the standard procedure is to hold context constant. In a typical brightness study the essential stimulus might be the intensity of the light or a difference between the light and the background. The two are perfectly confounded. This issue is examined in the case of audition. Judgments of the loudness of a tone depend on how much that tone differs from the previous tone in both pitch and loudness. To judge loudness people first seem to process the stimulus object in terms of differences between it and other aspects in the situation; only then do they assess the feature of interest. Psychophysical judgments will therefore be better interpreted by theories of attention that are based in biology or psychology than those that are based in classical physics. (shrink)

The measurement of sensory intensity has had a long history, attracting the attention of investigators from many disciplines including physiology, psychology, physics, mathematics, philosophy, and even chemistry. While there has been a continuing doubt by some that sensation has the properties necessary for measurement, experiments designed to obtain estimates of sensory intensity have found that a general rule applies: Equal stimulus ratios produce equal sensory ratios. Theories concerning the basis for this simple psychophysical rule are discussed, with emphasis given to (...) the physical correlate theory, which considers judgments of subjective magnitudes to be based upon estimates of physical dimensions that vary regularly with changes in degree of stimulation. For the most thoroughly investigated sensory scales, brightness and loudness, the physical correlate is considered to be distance. Our “tacit knowledge” of the sensory effects of changing distance plays an essential role in matching motor activities to environmental conditions and in ensuring accurate perceptual evaluations through brightness and loudness constancies. In psychophysical experiments, subjects apparently use this same tacit knowledge when required to estimate relative subjective magnitudes. The evidence related to the physical correlate theory is summarized, and it is concluded that, while under appropriate conditions we demonstrate considerable skill in evaluating environmental relationships, we are quite unable to estimate the neurophysiological nature or quantity of sensory response. A psychophysics devoted to studying conditions required for accuracy and conditions producing errors in the perception of environmental relationships would seem to be more valuable than one devoted to subjective magnitudes.

I analyse the political, economic, and cultural circumstances that have given rise to persistent political disputes about race (known colloquially as “the culture war”) among a subset of Americans. I argue that they point to a deep tension between widely held normative aspirations and pervasive and readily observable material facts about our society. The characterological pathologies this gives rise to are discussed, and a normatively preferable path forward for an individual attempting to reconcile themselves to the current social order is (...) suggested.

In this outstanding introduction, Constance Meinwald covers all of Plato's philosophy and shows how he shaped the landscape of Western philosophy. Beginning with a helpful overview of what is known about Plato's life and times, she clearly explains and assesses Plato's fundamental arguments and ideas. These include the importance of Plato's view of what philosophy is and the distinctive way in which his most important arguments are presented in dialogues; his theories of ethics addressed through the fundamental and enduring questions (...) happiness and virtue; his influential treatments of the soul and immortality; the lasting contributions he made to the study of metaphysics and the nature of knowledge through his theory of the Forms; and his enduring and controversial insights into political and social thought in the context of his theories of human nature. Throughout, Constance Meinwwald draws expertly on Plato's most important dialogues to present a thorough and lively picture of his philosophy. Essential reading for students of ancient philosophy and Classics, Plato is an ideal introduction to arguably the greatest of all Western philosophers. (shrink)

What differentiates scientific research from non-scientific inquiry? Philosophers addressing this question have typically been inspired by the exalted social place and intellectual achievements of science. They have hence tended to point to some epistemic virtue or methodological feature of science that sets it apart. Our discussion on the other hand is motivated by the case of commercial research, which we argue is distinct from (and often epistemically inferior to) academic research. We consider a deflationary view in which science refers to (...) whatever is regarded as epistemically successful, but find that this does not leave room for the important notion of scientific error and fails to capture distinctive social elements of science. This leads us to the view that a demarcation criterion should be a widely upheld social norm without immediate epistemic connotations. Our tentative answer is the communist norm, which calls on scientists to share their work widely for public scrutiny and evaluation. (shrink)

Philosophers of science debate the proper role of non-epistemic value judgements in scientific reasoning. Many modern authors oppose the value free ideal, claiming that we should not even try to get scientists to eliminate all such non-epistemic value judgements from their reasoning. W. E. B. Du Bois, on the other hand, has a defence of the value free ideal in science that is rooted in a conception of the proper place of science in a democracy. In particular, Du Bois argues (...) that the value free ideal must be upheld in order to, first, retain public trust in science and, second, ensure that those best placed to make use of scientifically acquired information are able to do so. This latter argument turns out to relate Du Bois’ position on the value free ideal in science to his defence of epistemic democracy. In this essay I elaborate, motivate, and relate to the modern debate, Du Bois’ under-appreciated defence of the value free ideal. (shrink)

Preferably scientific investigations would promote true rather than false beliefs. The phenomenon of fraud represents a standing challenge to this veritistic ideal. When scientists publish fraudulent results they knowingly enter falsehoods into the information stream of science. Recognition of this challenge has prompted calls for scientists to more consciously adopt the veritistic ideal in their own work. In this paper I argue against such promotion of the veritistic ideal. It turns out that a sincere desire on the part of scientists (...) to see the truth propagated may well promote more fraud rather than less. (shrink)

Social scientists report difficulties in drawing out testable predictions from the literature on intersectionality theory. We alleviate that difficulty by showing that some characteristic claims of the intersectionality literature can be interpreted causally. The formalism of graphical causal modeling allows claims about the causal effects of occupying intersecting identity categories to be clearly represented and submitted to empirical testing. After outlining this causal interpretation of intersectional theory, we address some concerns that have been expressed in the literature claiming that membership (...) in demographic categories can have causal effects.

What is the connection between capitalism and racial hierarchy? In line with the tradition known as `the theory of racial capitalism' we show that the latter can functionally support the former. As a social construction, race has just those features which allow it to facilitate the sort of stable, inequitable distributions of resources that tend to emerge in capitalist systems. We support this claim using techniques from evolutionary game theory and cultural evolutionary theory, and end by discussing the normative political (...) consequences of this relationship. (shrink)

This paper addresses the problem of judgment aggregation in science. How should scientists decide which propositions to assert in a collaborative document? We distinguish the question of what to write in a collaborative document from the question of collective belief. We argue that recent objections to the application of the formal literature on judgment aggregation to the problem of judgment aggregation in science apply to the latter, not the former question. The formal literature has introduced various desiderata for an aggregation (...) procedure. Proposition-wise majority voting emerges as a procedure that satisfies all desiderata which represent norms of science. An interesting consequence is that not all collaborating scientists need to endorse every proposition asserted in a collaborative document. (shrink)

I discuss the peculiar optimism present in an influential strand of analytic philosophy, and compare it with the more morose philosophical anthropology one might naturally pick up from other fields.

This article builds on recent accounts of diffuse and complex agentic practices in the global South by drawing on ethnographic data gathered in northwestern Ghana among the Dagaaba. Contemporary feminist discourses and theories, particularly in contexts in the global South, have sought to draw attention to the multifaceted ways in which women exercise agency in these contexts. Practices that in the past were perceived as instruments of women's subordination or as re-inscribing their oppression have been re/interpreted as agentic. Agentic practices (...) are theorized in more fluid terms than the binary pairing of agent/victim debates permit. Dagaaba contexts are deeply pervaded by beliefs in supernatural power forms, and these forces dis/empower certain forms of agentic acts. This article demonstrates that key factors combining with male power to regulate women's exercise of agency are perceived mystical forces. I argue that, in order not to risk missing agency—or rather “misdescribing” it—in the context of Dagaaba and most parts of sub-Saharan Africa, where the belief in mystical forces is profoundly pervasive, the role of these power forms as important determinants of the form that agentic practices assume—and more broadly, the way power works—needs critical attention in feminist theorizing.

In this article, I examine the marginalisation and abjection of strongwilled and assertive women in Dagaaba settings in rural north-western Ghana. This is done by paying attention to a local identity category known as pog gandao—‘a woman who is more than a man’. The pog gandao, or what I gloss as the wilful woman, concept is used by men and women locally to stigmatise hard-working and assertive Dagaaba women. Drawing inspiration from the reappropriation and redeployment of queer abjection for the (...) subversion of homophobia and the violence of compulsory heterosexuality, I demonstrate how such naming or shaming into the position of a pog gandao serves to hamper initiatives by enterprising and talented Dagaaba women. Being labelled as pog gandao, it appears, is even to lose one’s status in normative gender presentation as a woman; it means to transcend into a realm beyond the masculine. But this transcendence is not enviable due to its potential to expose the subject in question to perceived supernatural harm, a serious matter in this cultural context whereby the world of human affairs is understood as thoroughly saturated with supernatural forces that structure daily and ritual comportment. I argue that the shaming interpellation of pog gandao works as the most powerful weapon against wilful women in oppressive male-centric institutions of the Dagaaba. And yet, this stigmatised interpellation also has great emancipating potential, and I conclude by exploring ways to reclaim it for undermining female subordination, and for both empowering women and for feminist politics.

The Parmenides is notorious for the criticisms it directs against Plato's own Theory of Forms, as presented in the middle period. But the second and major portion of the dialogue has generally been avoided, despite its being offered as Plato's response to the problems; the text seems intractably obscure, appearing to consist of a series of bad arguments leading to contradictory conclusions. Carefully analyzing these arguments and the methodological remarks which precede them, Meinwald shows that to understand Plato's response we (...) need to recognize his important distinction between two kinds of predication. Read in the light of this distinction, the arguments can be seen to be sound, and the contradictions merely apparent. Meinwald then proceeds to demonstrate the direct application of Plato's crucial innovation in solving the problems of the first part of the dialogue, including the infamous Third Man. On Meinwald's interpretation, the new distinction is associated with developments in metaphysics which take Plato well beyond the problems commonly thought to tell against Platonism. (shrink)

This paper describes differences in two perspectives on the idea of virtue as a theoretical foundation for positive organizational ethics (POE). The virtue ethics perspective is grounded in the philosophical tradition, has classical roots, and focuses attention on virtue as a property of character. The positive social science perspective is a recent movement (e.g., positive psychology and positive organizational scholarship) that has implications for POE. The positive social science movement operationalizes virtue through an empirical lens that emphasizes virtuous behaviors. From (...) a virtue ethics perspective, a behaviorally based account of virtue is a weak theory of virtue. Observations are suggested for integrating the two perspectives. First, virtue should always be understood as an excellence and is often an optimal point between extreme dysfunctions on continuum of potential states. Second, an empirical exploration of virtue needs to account for character and context. Finally, the properties of organization-level virtue need to be further specified and explored. Implications and directions for future research are discussed. (shrink)

I outline a defence of a naive group-level standpoint epistemology. According to this view then under conditions often met in real situations of oppression, it is the majority view on questions of import to those marginalised by oppression that ought to be treated as deference worthy. I further argue that this view is inspired by and coheres well with various doctrines laid out and defended by W.E.B. Du Bois, making this a recognisably Duboisian vision of standpoint epistemology. The central conceptual (...) move is to relate principles of social epistemology under conditions of oppression that were of great interest to Du Bois with the conditions for group accuracy that have been studied by social-choice theorists working on Condorcet’s Jury Theorem, as well as contemporary epistemological work on group polarisation. I argue that once these elements are brought together a surprisingly cogent case for deference to the simple majority view of the marginalised can often be made. (shrink)

The Agriculture, Food and Human Values Society and the journal _Agriculture and Human Values_ provided a crucial intellectual space for the early transdisciplinary critique of the industrial agrifood system. This paper describes that process and presents the concept of “The Doctors of Agrifood Studies” as a metaphor for the key role critical agrifood social scientists played in documenting the unsustainability of conventional agriculture and working to create an alternative, ethical, sustainable agrifood system. After the introduction, the paper details the “Critical (...)

ABSTRACT Evolution cartoons served polemical and satirical purposes even before Darwin published On the Origin of Species, and they proliferated afterward. Yet even though Victorian evolution cartoons often pictured Darwin himself as a personification of his theory, by the time of the Scopes trial controversy in the 1920s cartoons about evolution had come to popularize ironically non‐Darwinian views of evolution. Cartoons repeated, reflected, and perpetuated teleological views of evolution and often implicitly associated evolution with prevalent attitudes about race, gender, and (...) social hierarchies. Cartoons drew on old iconographic traditions, expanding them to fit changing historical circumstances, forming a lasting cartoon lexicon. Though adaptable and protean, the language of evolution cartoons, like any language, carries its history with it, and in them we can read the history of the cultural context of evolution controversies.

The logical empiricists expressed a consistent attitude to racial categorisation in both the ethical and scientific spheres. Their attitude may be captured in the following slogan: human racial taxonomy is an empirically meaningful mode of classifying persons that we should refrain from deploying.

Using a decision theoretic model of scientists’ time allocation between potential research projects I explain the fact that on average women scientists publish less research papers than men scientists. If scientists are incentivised to publish as many papers as possible, then it is necessary and sufficient for a productivity gap to arise that women scientists anticipate harsher treatment of their manuscripts than men scientists anticipate for their manuscripts. I present evidence that women do expect harsher treatment and that scientists’ are (...) incentivised to publish as many papers as possible, and discuss some epistemological consequences of this conjecture.

Studies of occupational sex segregation rely on the sociocultural model to explain why some occupations are numerically dominated by women and others by men. This model argues that occupational sex segregation is driven by norms about gender-appropriate work, which are frequently conceptualized as gender-typed skills: work-related tasks, abilities, and knowledge domains that society views as either feminine or masculine. The sociocultural model thus explains the primary patterns of occupational sex segregation, which conform to these norms: Requirements for feminine skills increase (...) with women’s representation in the occupation. However, the model does not adequately explain cases of segregation that deviate from these norms or investigate the ways in which feminine and masculine skills co-occur in occupations. The present study fills these gaps by evaluating two previously untested explanations for deviations from the sociocultural model. The findings show that requirements for physical strength increase with women’s representation in professional occupations because physical strength skills co-occur with substantially higher requirements for feminine skills that involve helping and caring for others. These results indicate that the sociocultural model, and more generally explanations for how gender norms drive occupational sex segregation, can be improved by examining patterns of gender-typed skill co-occurrence.

From the grey stone terrace in front of Russell’s cottage, the whole Vale of Ffestiniog opens out to the shining estuary and the sea.2 The terrace has three tall, clipped, very prim looking bay trees; and all the cottage’s eight windows and two doors open out onto it; and Russell will tell you (with a lightly sardonic tone in his voice) that there were originally six trees, but that A.yS. Neill’s small scholars cut down three of them. (A.yS.

Local knowledge (both technological and sociological) and communication systems represent a logical starting point and a rich body of resources for successful agricultural research, development, and extension (RD&E). Drawing upon concrete examples from Asia, Africa, and Latin America, this essay presents an overview of definitions, topics, and applications of local knowledge in agricultural RD&E. Also noted are caveats, future research and training needs, and human values issues related to the study and utilization of local knowledge systems and their products.
