Abstract Since their inception, distributional models of semantics have been criticized as inadequate cognitive theories of human semantic learning and representation. A principal challenge is that the representations derived by distributional models are purely symbolic and are not grounded in perception and action; this challenge has led many to favor feature-based models of semantic representation. We argue that the amount of perceptual and other semantic information that can be learned from purely distributional statistics has been underappreciated. We compare the representations (...) of three feature-based and nine distributional models using a semantic clustering task. Several distributional models demonstrated semantic clustering comparable with clustering-based on feature-based representations. Furthermore, when trained on child-directed speech, the same distributional models perform as well as sensorimotor-based feature representations of children’s lexical semantic knowledge. These results suggest that, to a large extent, information relevant for extracting semantic categories is redundantly coded in perceptual and linguistic experience. Detailed analyses of the semantic clusters of the feature-based and distributional models also reveal that the models make use of complementary cues to semantic organization from the two data streams. Rather than conceptualizing feature-based and distributional models as competing theories, we argue that future focus should be on understanding the cognitive mechanisms humans use to integrate the two sources.

In 1688 the Irish scientist and politician William Molyneux sent a letter to the philosopher John Locke. In it, he asked him a question: could someone who was born blind, and able to distinguish a globe and a cube by touch, be able to immediately distinguish and name these shapes by sight if given the ability to see? -/- The philosophical puzzle offered in Molyneux’s letter fascinated not only Locke, but major thinkers such as Leibniz, Berkeley, Diderot, Reid, and numerous (...) others including psychologists and cognitive scientists today. Does such a question represent a philosophical puzzle or a problem that can be solved by experimental tests? Can vision be fully restored after blindness? What is the relation between vision and touch? Are the senses linked through learning or bound at birth? -/- Molyneux’s Question and the History of Philosophy is a major collection of essays that explore the long-standing issues Molyneux’s problem presents to philosophy of mind, perception and the senses. In addition, the volume considers the question from an interdisciplinary angle, examines the pre-history of the question, and aspects of it that have been ignored, such as perspectives from religion and disability. -/- As such, Molyneux’s Question and the History of Philosophy presents a set of philosophically rich, empirically informed, and scientifically rigorous original investigations into this famous puzzle. It will be of great interest to students and researchers in philosophy, psychology, and the cognitive sciences including neuroscience, neurobiology and ophthalmology, as well as those studying the mind, perception and the senses.

Molyneux’s question, whether the newly sighted might immediately recognize tactilely familiar shapes by sight alone, has produced an array of answers over three centuries of debate and discussion. I propose the first pluralist response: many different answers, both yes and no, are individually sufficient as an answer to the question as a whole. I argue that this is possible if we take the question to be cluster concept of sub-problems. This response opposes traditional answers that isolate specific perceptual features as (...) uniquely applicable to Molyneux’s question and grant viability to only one reply. Answering Molyneux’s question as a cluster concept may also serve as a methodology for resolving other philosophical problems. (shrink)

In response to the publication of a lively new volume on modern Indian philosophy during the nineteenth and twentieth centuries, this essay offers four brief interventions intended to prompt further critical reflection on the concept of the Indian Renaissance.

I’m not sure how much knowledge everyone already has, so I’d like to start with a little questionnaire. On a card, say for each of the following topics whether you’re familiar with the topic, have heard of it but aren’t familiar with it, or have never heard of it.

Gleeson, Brian Among peoples today, the phenomenon of faith takes many different forms. Beyond the different religious expressions of faith within the great world religions, there exists a variety of other forms and objects of faith. Terence Tilley discusses these around his 'working definition of faith' as a relationship-'the relationship between one and the irreducible energizing source of meaning and centre of value in one's life'. Metaphorically speaking, those dominant sources of meaning, value, and energy for their devotees are (...) their 'gods'. Among those that Tilley identifies are the following: the family, the nation, secular humanism, truth, justice, money, success, pleasure, the body beautiful, power. He suggests that 'discovering our gods' involves asking such questions as these: For what do we live? What energises our life? What would we die for? Why would we die for that? (shrink)

Fast and effective detection of the causative agent of malaria in humans, protozoan Plasmodium parasites, is of crucial importance for increasing the effectiveness of treatment and to control a devastating disease that affects millions of people living in endemic areas. The microscopic examination of Giemsa‐stained blood films still remains the gold‐standard in Plasmodium detection today. However, there is a high demand for alternative diagnostic methods that are simple, fast, highly sensitive, ideally do not rely on blood‐drawing and can potentially be (...) conducted by the patients themselves. Here, the history of Plasmodium detection is discussed, and advantages and disadvantages of diagnostic methods that are currently being applied are assessed. (shrink)

This text represents an exploration of the possible significance of Bernard S. Cohn's 1980 essay, `History and Anthropology: The State of Play', for understanding the present of historical anthropology and its futures. My discussion has two aims: (1) to reflect on both Bernard S. Cohn's pedagogy and mode of inquiry; and (2) to explore the complexity and nuance of citationality as a generative principle within the constitution of historical anthropology's subject. Toward this, I examine Cohn's notion of `the colonial situation' (...) and reflect on how the emergence of the human sciences is intertwined with the proliferation of colonialism's enduring legacy within postcoloniality.

Initially conceived as an interview with the hybrid media artist Brian Goeltzenleuchter, this text gradually took the form of a conversation on various issues regarding olfactory art and the aesthetic significance of smell. Framing the artistic uses of odours in the context of contemporary art, the paper discloses some of its foundational traits, variations, and underlying impulses. By commenting on Goeltzenleuchter’s olfactory artworks through a philosophical perspective, this contribution covers a number of subjects including the notion of atmosphere, the (...) socio-cultural values and narratives conveyed by scents, the suggestive relationship between spaces and aromas, and the phenomenology of smells as compared to the experience of sounds. Consistent with how smell perception unfolds, the dialogue flows in a form that is not rigidly structured but airy, ephemeral, and fluid, developing a sequence of insights whose aim is, rather than scrutinising a specific topic, to evoke the essence of olfactory poetics as a whole.

How does the mind attribute external causes to internal sensory experiences? Adam Smith addresses this question in his little known essay ‘Of the External Senses.’ I closely examine Smith's various formulations of this problem and then argue for an interpretation of his solution: that inborn perceptual mechanisms automatically generate external attributions of internal experiences. I conclude by speculating that these mechanisms are best understood to operate by simulating tactile environments.

This chapter starts by addressing Thomas Aquinas’ idea of God, and then discusses ways in which we cannot defend belief in his existence. It goes on to expand on the basis on which we can claim knowledge of God's existence, through looking at the cause of effects that are evident to us; these are Aquinas’ ‘Five Ways’, which are discussed in detail. Further sections of the chapter cover the existence argument, creation, and the beginning of the world.

In recent years, a consensus has developed among both affirmative action's advocates and opponents that in relation to the typical white applicant, the effects of minority preferencing are minimal. In this essay, the aim is to clarify the mathematics of affirmative action's impact on majority applicants, and to flag the distinction between that question and affirmative action's opportunity cost. First, the essay establishes the level of agreement among judges and academics on the triviality of affirmative action's effect on the regular (...) white applicant's prospects of success. Second, it demonstrates how the prevailing position on the impact of minority preferencing on the white applicant is flawed - as regards both the calculation of relative admission likelihood and the application of the matriculant yield variable. Making use of a number of case studies reviewed in the literature, it shows how those studies, properly understood, convey a rather different picture of the arithmetic of minority preferencing. The essay concludes by challenging the tendency to take the effects of affirmative action (on both preferred and non-preferred applicants) as exclusively indicative of its costs. (shrink)

Homology continues to be a concept of central importance in the study of phylogenetic relations, but its relation to ontogenetic processes remains problematical. A definition of homology in terms of equivalent morphogenetic processes is defined and applied to the comparative study of tetrapod limbs. This allows for a consistent treatment of relations of similarity and difference of appendage structure in vertebrates, and the distinction between fishes fins and tetrapod limbs in terms of the concept of equivalence is described. The role (...) of genes can also be clarified in this context, in particular the influence of the Hox 4 complex in determining digit character and the homeotic transformations that arise from changes in their expression patterns. It is argued that these observations are not compatible with the notion of homology between individual digits (I, II, III, etc.) across the tetrapods, and that homology cannot be consistently identified with gene action. The relations between homology and the properties of the morphogenetic limb field are discussed. (shrink)

Abstract:Those interested in environmental protection are frequently motivated by the idea that environmental destruction is "bad" while environmental conservation is "good." In some cases, this is based merely on the anthropocentric instrumental value of the environment in relation to humans, but it seems more common that this motivation is generated by a belief that non-humans have intrinsic value, at least at some level of biotic organization. Yet, there is no basis for this claim that is not rooted in either theism (...) or some other form of arbitrary value judgement that, in a materialistic worldview, has no basis outside of the believer's mind. Thus, secular-based environmental ethics that do not rely on theistic or metaphysical assumptions can never be prescriptive; materialistic conservation ethics can never prescribe behavior, they can only describe the arbitrary and fundamentally meaningless values of the philosopher.
