This open access edited book provides new thinking on scientific identity formation. It thoroughly interrogates the concepts of community and identity, including both historical and contemporaneous analyses of several scientific fields. Chapters examine whether, and how, today’s scientific identities and communities are subject to fundamental changes, reacting to tangible shifts in research funding as well as more intangible transformations in our society’s understanding and expectations of technoscience. In so doing, this book reinvigorates the concept of scientific community. Readers will discover (...) empirical analyses of newly emerging fields such as synthetic biology, systems biology and nanotechnology, and accounts of the evolution of theoretical conceptions of scientific identity and community. With inspiring examples of technoscientific identity work and community constellations, along with thought-provoking hypotheses and discussion, the work has a broad appeal. Those involved in science governance will benefit particularly from this book, and it has much to offer those in scholarly fields including sociology of science, science studies, philosophy of science and history of science, as well as teachers of science and scientists themselves.

Background: There is general consensus internationally that unfair distribution of the benefits of research is exploitative and should be avoided or reduced. However, what constitutes fair benefits, and the exact nature of the benefits and their mode of provision can be strongly contested. Empirical studies have the potential to contribute viewpoints and experiences to debates and guidelines, but few have been conducted. We conducted a study to support the development of guidelines on benefits and payments for studies conducted by the (...) KEMRI-Wellcome Trust programme in Kilifi, Kenya. Methods: Following an initial broad based survey of cash, health services and other items being offered during research by all programme studies (n = 38 studies), interviews were held with research managers (n = 9), and with research staff involved in 8 purposively selected case studies (n = 30 interviewees). Interviews explored how these ‘benefits’ were selected and communicated, experiences with their administration, and recommendations for future guidelines. Data fed into a consultative workshop attended by 48 research staff and health managers, which was facilitated by an external ethicist.FindingsThe most commonly provided benefits were medical care (for example free care, and strengthened quality of care), and lunch or snacks. Most cash given to participants was reimbursement of transport costs (for example to meet appointments or facilitate use of services when unexpectedly sick), but these payments were often described by research participants as benefits. Challenges included: tensions within households and communities resulting from lack of clarity and agreement on who is eligible for benefits; suspicion regarding motivation for their provision; and confusion caused by differences between studies in types and levels of benefits. Conclusions: Research staff differed in their views on how benefits should be approached. Echoing elements of international benefit sharing and ancillary care debates, some research staff saw research as based on goodwill and partnership, and aimed to avoid costs to participants and a commercial relationship; while others sought to maximise participant benefits given the relative wealth of the institution and the multiple community needs. An emerging middle position was to strengthen collateral or indirect medical benefits to communities through collaborations with the Ministry of Health to support sustainability. (shrink)

Molyneux's Question (MQ) concerns whether a newly sighted man would recognize/distinguish a sphere and a cube by vision, assuming he could previously do this by touch. We argue that (MQ) splits into questions about (a) shared representations of space in different perceptual systems, and about (b) shared ways of constructing higher dimensional spatiotemporal features from information about lower dimensional ones, most of the technical difficulty centring on (b). So understood, MQ resists any monolithic answer: everything depends on the constraints (...) faced by particular perceptual systems in extracting features of higher dimensionality from those of lower. Each individual question of this type is empirical and must be investigated separately. We present several variations on MQ based on different levels of dimensional integration—some of these are familiar, some novel adaptations of problems known elsewhere, and some completely novel. Organizing these cases in this way is useful because it unifies a set of disparate questions about intermodal transfer that have held philosophical and psychological interest, suggests a new range of questions of the same type, sheds light on similarities and differences between members of the family, and allows us to formulate a much-augmented set of principles and questions concerning the intermodal transfer of spatiotemporal organization. (shrink)

What philosophical issue or issues does Molyneux’s question raise? I concentrate on two. First, are there any properties represented in both touch and vision? Second, for any such common perceptible, is it represented in the same way in each, so that the two senses support a single concept of that property? I show that there is space for a second issue here, describe its precise relations to Molyneux’s question, and argue for its philosophical significance. I close by arguing (...) that Gareth Evans conflated the two issues, and thereby provide further grounds for distinguishing them. (shrink)

William Molyneux was born in Dublin, studied in Trinity College Dublin, and was a founding member of the Dublin Philosophical Society (DPS), Ireland’s counterpart to the Royal Society in London. He was a central figure in the Irish intellectual milieu during the Early Modern period and – along with George Berkeley and Edmund Burke – is one of the best-known thinkers to have come out of that context and out of Irish thought more generally. In 1688, when Molyneux (...) wrote the letter to Locke in which he posed the now famous question about a man born blind made to see, he was an active member of the DPS and was on familiar terms with several other key figures in Irish philosophy at the time. For the most part, Irish thinkers in the seventeenth and eighteenth centuries answered “no” to Molyneux’s question of whether a blind man made to see could distinguish, by sight alone, between a cube and a sphere. (shrink)

If the sight of cortically blind people were restored, could they visually recognize a cube or a sphere? This is Molyneux’s question. I argue that the answer to this question depends on the specificities of the mental setup of these cortically blind people. Some cortically blind people have (sometimes quite vivid) visual imagery. Others don’t. The answer to Molyneux’s question depends on whether the blind subjects have had visual imagery before their sight was restored. If they did, the (...) answer to Molyneux’s question is yes, if they didn’t, the answer is no. There is no generic answer to Molyneux’s question. (shrink)

Amongst those who answered Molyneux’s question in the negative or at least not in the positive, George Berkeley is of particular interest because he argued for a very radical position. Most of his contribution to the discussion can be found in his Essay towards a New Theory of Vision. I will give an exposition of his view (2) and then move on to a critical discussion of this kind of view, - what one could call the “Berkeleian view” (3). (...) I think that the problems of what has become a standard negative answer to the question (mainly brought forward by empiricists) become very clear in Berkeley’s case and one can also learn a lot from this. (shrink)

This chapter explores how our understanding of Molyneux’s question, and of the possibility of an experimental resolution to it, should be affected by recognizing the complexity that is involved in reidentifying shapes and other spatial properties across differing sensory manifestations of them. I will argue that while philosophers today usually treat the question as concerning ‘the relations between perceptions of shape in different sensory modalities’ (Campbell 1995, 301), in fact this is only part of the question’s real interest, and (...) that the answer to the question also turns on how shape is perceived within each of sight and touch individually. (shrink)

The aim of this chapter is to shed new light on the question of what newly sighted subjects are capable of seeing on the basis of previous experience with mind- independent, external objects and their properties through touch alone. This question is also known as "Molyneux’s question." Much of the empirically driven debate surrounding this question has been centered on the nature of the representational content of the subjects' visual experiences. It has generally been assumed that the meaning of (...) "seeing" deployed in these disputes is more or less clear and unproblematic, and therefore requires no analysis or clarification. In this chapter, we wish to challenge this assumption. We argue that getting clear on the meaning of "seeing" is the only feasible way to determine whether the empirical attempts to answer Molyneux’s question accurately capture what newly sighted subjects are in fact capable of seeing. Specifically, we show that the dominant interpretations of the empirical results from a recent study (Held et al., 2011) fail to take into account that seeing can be not only purely visual but also epistemic in that it requires background knowledge (such as what an object with a particular viewpoint-independent shape looks like from a particular perspective).

More than 300 years ago, William Molyneux raised an important and puzzling question which still creates a lot of controversy. What is known as “Molyneux’s question“ was made famous by John Locke’s quote of Molyneux in the second edition of the Essay Concerning Human Understanding: “Suppose a Man born blind, and now adult, and taught by his touch to distinguish between a Cube, and a Sphere of the same metal, and nighly of the same bigness, so as (...) to tell, when he felt one and t’other, which is the Cube, which the Sphere. Suppose then the Cube and Sphere placed on a Table, and the Blind Man to be made to see. Quaere, Whether by his sight, before he touch’d them, he could now distinguish, and tell, which is the Globe, which the Cube.“ I argue for a positive answer to the question. (shrink)

Molyneux’s Question, also known as Molyneux’s Problem, soon became a fulcrum for early research in the epistemology of concepts, challenging common intuitions about how our concepts originate, whether sensory features differentiate concepts, and how concepts are utilized in novel contexts. It was reprinted and discussed by a wide range of early modern philosophers, including Gottfried Leibniz, George Berkeley, and Adam Smith, and was perhaps the most important problem in the burgeoning discipline of psychology of the 18th Century. The (...) question has since undergone various stages of development, both as a mental exercise and as an experimental paradigm, garnering a variety of both affirmative and negative replies in the next three centuries of debate and deliberation. (shrink)

After more than three centuries, Molyneux's question continues to challenge our understanding of cognition and perceptual systems. Locke, the original recipient of the question, approached it as a theoretical exercise relevant to long-standing philosophical issues, such as nativism, the possibility of common sensibles, and the empiricism-rationalism debate. However, philosophers were quick to adopt the experimentalist's stance as soon as they became aware of recoveries from congenital blindness through ophtalmic surgery. Such recoveries were widely reported to support empiricist positions, suggesting (...) that the question had found its empirical answer. Contrary to this common view, we argue that studies of patients recovering from early blindness through surgery cannot provide an answer. In fact, because of the very nature of such ophtalmological interventions it is impossible to test the question in the empirical conditions outlined by Molyneux. Thus we propose that Molyneux's question be treated as an early thought experiment of a specific kind. Although thought experiments of this kind cannot be turned into actual experimental conditions, they provide a conceptual restructuring of theories. Such restructuring in turn leads to new predictions that can then be tested by normal experiments. In accord with this interpretation, we show that Molyneux's question can be analyzed into a hierarchy of specific questions about vision in its phenomenal and sensory-motor components. Some of these questions do lead to actual experimental conditions that could be studied empirically. (shrink)

I propose a reading of Berkeley's Essay towards a New Theory of Vision in which Molyneux-type questions are interpreted as thought experiments instead of arguments. First, I present the general argumentative strategy in the NTV, and provide grounds for the traditional reading. Second, I consider some roles of thought experiments, and classify Molyneux-type questions in the NTV as constructive conjectural thought experiments. Third, I argue that (i) there is no distinction between Weak and Strong Heterogeneity theses in the (...) NTV; (ii) that Strong Heterogeneity is the basis of Berkeley's theory; and (iii) that Molyneux-type questions act as illustrations of Strong Heterogeneity. (shrink)

Neste trabalho, nos propomos percorrer algumas etapas do debate sobre a relevância das causas finais nas investigações físicas, que levou Leibniz a confrontar sua filosofia, de modo particular, com o cartesianismo e, mais em geral, com uma concepção estritamente mecanicista da natureza. Serão seguidos aqueles indícios que se encontram na obra de Leibniz, ao procurar pelas referências a Molyneux, um dos primeiros a receber e divulgar a perspectiva leibniziana, e, além disso, um dos poucos interlocutores com os quais se (...) instaurou um diálogo de tons cordiais. Tentaremos mostrar que, todavia, tal troca não polêmica é fruto de um desentendimento de fundo entre os dois intelectuais. (shrink)

Molyneux's Question, that is, “Suppose a man born blind, and now adult, and taught by his touch to distinguish between a cube and a sphere... and the blind man made to see: Quaere, whether by his sight, before he touched them, he could now distinguish, and tell, which is the globe, which the cube”, was discussed by many theorists in the 17th and 18th centuries, and has recently been addressed by contemporary philosophers interested in the nature, and identity conditions, (...) of perceptual concepts. My main concern in this paper is to argue – against Evans, Campbell, and a number of other contemporary philosophers – that a test of the sort Molyneux envisioned, at least if carefully designed and administered, can indeed be a crucial experiment for the claim that we deploy the same perceptual concepts when identifying shapes by sight and by touch. I will explore some implications of this argument for a theory of recognitional concepts. And I’ll try to trace out some unhappy consequences of various alternative views. (shrink)

William Molyneux (1656–1698) was an Irish experimental philosopher and politician, who played a major role in the intellectual life in seventeenth-century Dublin. He became Locke’s friend and correspondent in 1692 and was probably Locke’s philosophically most significant correspondent. Locke approached Molyneux for advice for revising his Essay concerning Human Understanding as he was preparing the second and subsequent editions. Locke made several changes in response to Molyneux’s suggestions; they include major revisions of the chapter ‘Of Power’ (2.21), (...) the addition of the chapter ‘Of Identity and Diversity’ (2.27), and the addition of the so-called Molyneux Problem (2.9.8). Molyneux repeatedly requested that Locke develops his views on morality. Additionally, their correspondence turned to questions concerning education and Molyneux’s keen interest in the topic likely prompted Locke to publish Some Thoughts Concerning Education in 1693. Moreover, Molyneux drew on Locke’s anonymously published Two Treatises of Government in his The Case of Ireland’s Being Bound by Acts of Parliament in England, Stated, which was first published in the spring of 1698. Molyneux revealed Locke’s authorship of Two Treatises against Locke’s will, yet their friendship continued until Molyneux’s untimely death in October 1698. (shrink)

Philosophical discussions of Molyneux's problem within contemporary philosophy of mind tend to characterize the problem as primarily concerned with the role innately known principles, amodal spatial concepts, and rational cognitive faculties play in our perceptual lives. Indeed, for broadly similar reasons, rationalists have generally advocated an affirmative answer, while empiricists have generally advocated a negative one, to the question Molyneux posed after presenting his famous thought experiment. This historical characterization of the dialectic, however, somewhat obscures the role (...) class='Hi'>Molyneux's problem has played in spawning debates within the empiricist tradition. Fortunately, the differences between various empiricist accounts have been widely recognized and discussed among historians of philosophy working on the topic. The focus of the present essay is to develop an interpretation of John Locke's views on Molyneux's problem that best coheres with his other views on human understanding as well as with the predominant scientific opinion about the nature of perception during the period in which he lived.

Pytanie Molyneux brzmi następująco: „Wystawmy sobie, iż niewidomy od urodzenia, obecnie człowiek dorosły, nauczył się odróżniać dotykiem sześcian od kuli i że stojący opodal ów niewidomy przejrzał; zapytuję, czy za pomocą odzyskanego wzroku, zanim dotknie tych przedmiotów, będzie mógł je rozpoznać i powiedzieć, który z nich jest kulą, a który sześcianem?” W niniejszym artykule wskazuję, że odpowiedź twierdząca, udzielona na to pytanie przez brytyjskiego filozofa Garetha Evansa jest nieprzekonująca, przede wszystkim dlatego, iż Evans nieświadomie pomija ilościowy czynnik dostępności informacji (...) zawartej w doświadczeniu zmysłowym.

Molyneux’s question famously asks about whether a newly sighted subject might immediately recognize, by sight alone, shapes that were already familiar to her from a tactile point of view. This paper addresses three crucial points concerning this puzzle. First, the presence of two different questions: the classic one concerning visual recognition and another one concerning vision-for-action. Second, the explicit distinction, reported in the literature, between ocular and cortical blindness. Third, the importance of making reference to our best neuroscientific account (...) on vision, ‘the two visual systems model’, in order to better address Molyneux’s problem. Then, by offering a new, deeper analysis of the relation between, and, this paper suggests that the subjects of Molyneux’s two different questions show the same visual impairment as brain-damaged subjects with different lesions of the visual cortex. In particular, the subject of the first question shows the same impairment in visual recognition as a visual agnosic subject, while the subject of the second question shows the same visual impairment in visuomotor processing as an optic ataxic subject. These impairments still hold even if ocular processing is restored. Therefore, I suggest the following. For the first classic question, the required experimental setting cannot be properly reached. By contrast, concerning the second question, based on the interpretation we select, either the answer is negative, or, as with the first question, the experimental setting cannot be properly reached. This proposal constitutes, with the other approaches offered in the literature, a further attempt to tackle the enormous complexity of Molyneux’s puzzle. (shrink)

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.

Schwenkler (2012) criticizes a 2011 experiment by R. Held and colleagues purporting to answer Molyneux’s question. Schwenkler proposes two ways to re-run the original experiment: either by allowing subjects to move around the stimuli, or by simplifying the stimuli to planar objects rather than three-dimensional ones. In Schwenkler (2013) he expands on and defends the former. I argue that this way of re-running the experiment is flawed, since it relies on a questionable assumption that newly sighted subjects will be (...) able to appreciate depth cues. I then argue that the second way of re-running the experiment is successful both in avoiding the flaw of original Held experiment, and in avoiding the problem with the first way of re-running the experiment.

A recent study published in Nature Neuroscience purports to have answered a question posed to Locke in 1688 by his friend William Molyneux, namely, whether ‘a man born blind and made to see’ would be able to identify, immediately and by vision alone, objects previously known only by touch. The answer, according to the researchers – and as predicted by Molyneux, as well as Locke, Berkeley, and others – is ‘likely negative. The newly sighted subjects did not exhibit (...) an immediate transfer of their tactile shape knowledge to the visual domain’. Since then, however, many commentators have argued that the answer is still not clear. Moreover, in the contemporary literature on Molyneux’s Question, and more generally on cross-modal perception and the individuation of the senses, it is sometimes hard to determine what question is being investigated. In this paper, I distinguish a number of different questions about the relation between visual and tactual perception that can arise when considering Molyneux’s... (shrink)

The Molyneux problem is one of the major questions addressed by early modern authors. Whereas Locke’s response to Molyneux’s question has been the subject of extensive scholarly discussion, Leibniz’s response has received comparatively little attention. This paper defends an interpretation of Leibniz’s nuanced response to the problem and criticizes a competing interpretation that has recently been proposed.

There have recently been various empirical attempts to answer Molyneux’s question, for example, the experiments undertaken by the Held group. These studies, though intricate, have encountered some objections, for instance, from Schwenkler, who proposes two ways of improving the experiments. One is “to re-run [the] experiment with the stimulus objects made to move, and/or the subjects moved or permitted to move with respect to them” (p. 94), which would promote three dimensional or otherwise viewpoint-invariant representations. The other is “to (...) use geometrically simpler shapes, such as the cube and sphere in Molyneux’s original proposal, or planar figures instead of three-dimensional solids” (p. 188). Connolly argues against the first modification but agrees with the second. In this article, I argue that the second modification is also problematic (though still surmountable), and that both Schwenkler and Connolly are too optimistic about the prospect of addressing Molyneux’s question empirically.

Reid’s discussion of Molyneux’s question has been neglected. The Inquiry discusses the question twice, offering opposing answers. The first discussion treats the underlying issue as concerning common perceptibles of touch and vision, and in particular whether in vision we originally perceive depth. Although it is tempting to treat the second discussion as doing the same, this would render pointless various novel features Reid introduces in reformulating Molyneux’s question. Rather, the issue now is whether the blind can form a (...) reasonable conception of visual appearances, a conception that would allow them to perform Molyneux’s task. In explaining why Reid thought they can, I draw on his account of primary quality concepts as independent of sensation; of concept possession as ability, not acquaintance with sensation; and of visual appearance itself as in key part a matter of the perception of a primary quality, visible figure. Thus the issue does not concern cross-modality, what vision has in common with touch; but how even what is central in vision is amodal, able to be grasped independently of any sensory mode. Reid’s second Molyneux discussion thereby forms a focus for the Inquiry’s central claims, and the rejection of the Ideal Theory they entail. (shrink)

Whatever the answer to Molyneux's question is, it is certainly not obvious that the answer is ‘yes’. In contrast, it seems clear that we should answer affirmatively a temporal variation on Molyneux's question, introduced by Gareth Evans. I offer a phenomenological explanation of this asymmetry in our responses to the two questions. This explanation appeals to the modality-specific spatial structure of perceptual experience and its amodal temporal structure. On this explanation, there are differences in the perception of spatial (...) properties in different modalities, but these differences do not stand in the way of the objectivity of perceptual experience.

If a man born blind were to gain his sight in later life would he be able to identify the objects he saw around him? Would he recognise a cube and a globe on the basis of his earlier tactile experiences alone? This was William Molyneux's famous question to John Locke and it was much discussed by English and French empiricists in the eighteenth century as part of the controversy over innatism and abstract ideas. Dr Morgan examines the whole (...) history of this debate: Locke's own (negative) answer to the question, the contributions of Berkeley, Condillac, Diderot and Voltaire and the factual accounts of early cataract operations and modern laboratory studies. He shows how this debate is involved in the development and eventual separation of philosophy and experimental psychology after the eighteenth century and considers why the original question is effectively still unanswered. This is one problem-area with its intricate cluster of connected conceptual and technical difficulties which suggests the need for some reunion or at least collaboration between the two subjects.

Molyneux asked whether a newly sighted person could distinguish a sphere from a cube by sight alone, given that she was antecedently able to do so by touch. This, we contend, is a question about general ideas. To answer it, we must ask (a) whether spatial locations identified by touch can be identified also by sight, and (b) whether the integration of spatial locations into an idea of shape persists through changes of modality. Posed this way, Molyneux’s Question (...) goes substantially beyond question (a), about spatial locations, alone; for a positive answer to (a) leaves open whether a perceiver might cross-identify locations, but not be able to identify the shapes that collections of locations comprise. We further emphasize that MQ targets general ideas so as to distinguish it from corresponding questions about experiences of shape and about the property of tangible (vs. visual) shape. After proposing a generalized formulation of MQ, we extend earlier work (“Many Molyneux Questions,” Australasian Journal of Philosophy 2020) by showing that MQ does not admit a single answer across the board. Some integrative data-processes transfer across modalities; others do not. Seeing where and how such transfer succeeds and fails in individual cases has much to offer to our understanding of perception and its modalities. (shrink)

Many contemporary philosophers contend that a positive answer to Molyneux’s Question -- the question of whether a “man born blind and made to see” would be able to identify spatial figures, without touching them, on first viewing -- requires that there be a *rational connection* between the representations of those figures afforded by vision and by touch. This paper explores the question of what this could mean if the representations are non-discursive, or “pure recognitional” concepts, and argues that the (...) most plausible answer to this question can be invoked to resolve analogous questions about the individuation of phenomenal concepts.

Might the once-blind recognize shapes familiar to the touch by sight alone? “Not”, replied both Locke and the question’s designer, William Molyneux. Leibniz, by contrast, replied, “yes” to Molyneux’s Question. However, Leibniz’s reason for his affirmative answer has yet to be discussed directly with any depth, a lacuna this paper seeks to address. The main contention of this paper is that Leibniz cannot think that sensory representations based on the sight and touch of shape sufficient for this task, (...) as several commentators have suggested. Rather, I argue that Leibniz’s answer is based on the ability of the once-blind to unconsciously employ “common sensibles,” representations of shape that are independent of sight and touch. (shrink)

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)

Molyneux’s question asks whether someone born blind, who could distinguish cubes from spheres using his tactile sensation, could recognize those objects if he received his sight. Locke says no: the newly sighted person would fail to point to the cube and call it a cube. Locke never provided a complete explanation for his negative response, and there are concerns of inconsistency with other important aspects of his theory of ideas. These charges of inconsistency rest upon an unrecognized and unfounded (...) assumption that seeing entails recognition. Locke’s negative answer to Molyneux’s question is consistent with his other philosophical commitments. (shrink)

Ordinary common sense suggests that we have just one set of shape concepts that we apply indifferently on the bases of sight and touch. Yet we understand the shape concepts, we know what shape properties are, only because we have experience of shapes. And phenomenal experience of shape in vision and phenomenal experience of shape in touch seem to be quite different. So how can the shape concepts we grasp and use on the basis of vision be the same as (...) the shape concepts we grasp and use on the basis of touch? I think this is the intuitive puzzle that underlies the question sent by the Dublin lawyer Molyneux to John Locke. This concerns a man born blind, who learns by the use of his touch to discriminate cubes from spheres. Suppose him now to gain the use of his sight. And suppose him to be presented with a cube and a sphere, of nighly the same bigness. Quaere, will he be able to tell, by the use of his vision alone, which is the sphere, and which the cube?
