Hallucinatory pictures are yet to be found picture-like artifacts that induce a hallucination of their content that cannot be intuitively explained by a look at the structure of the pictorial vehicle. Different accounts of depiction make different predictions about the possibility that such artifacts be considered as pictures. Some cases are presented that point towards the intuitive acceptability of hallucinatory pictures.

Agnes Arber (1879-1960) was a British botanist who was a leading plant morphologist during the first half of the 20th century. She also wrote on the history and philosophy of botany. I argue in this article that her philosophical work on form and on how the work of the mind and the eye relate to each other in morphological research are relevant to the science of today. Arber's unusual blend of interests - in botany, history, philosophy, and art - put (...) her in a unique position to examine issues of form. Even her unorthodox ideas on evolution can now be seen as fitting in well with discussions of natural selection as the predominant engine of evolutionary change. Arber's views also throw light on present work dealing with developmental plant genetics and with the study of protein form. I will further argue that her marginal position relative to institutional science, while it may have left her vulnerable to criticism, also made possible her deep philosophical reflections on morphology.

A distinctive feature of Merleau-Ponty’s thought is the central role he assigns style in generally characterizing embodied agents’ perceptual and cognitive functioning. Despite this, he says little to explain how he conceives style itself. This article therefore aims to clarify Merleau-Ponty’s notion of style and its significance within and beyond his work. It begins by surveying his broad application of the term and using his discussions of painting to reconstruct his conception of style, identifying two major roles Merleau-Ponty attributes it (...) in unifying intentional structures and founding conceptual meaning. His view is related to several competing philosophical conceptions of style to highlight its distinctiveness and some conceptual difficulties in adequately defining style. I then argue that Merleau-Ponty succeeds in coherently distinguishing style from rules by recognizing that style conceives pattern formation, especially the relation of general and particular, in a way contrasting with the identity-based thinking inherent in the functioning of rules. With this distinction I conclude that, although Merleau-Ponty overgeneralizes its role, his conception of style has broader philosophical significance in accurately capturing the nonmechanical cohesion of certain embodied intelligent activities (such as painting) and enabling better understanding of the variety of forms such activities can take.

This thesis begins with a succinct survey of theories of depiction and then turns to two highly influential contemporary philosophical accounts, namely, the aspect-recognition theory proposed by Dominic McIver Lopes, and Robert Hopkins’s experienced resemblance theory. The latter two theories of pictorial representation are presented in detail before objections to both accounts are presented and assessed. One of the central contentions of the thesis is that the aspect-recognition theory succumbs to a number of serious objections. First of all, this account (...) rests upon a philosophically problematic notion of semantic information and consequently fails to account adequately for the possibility of misrepresentation. Arguably the theory entails that all pictures are misrepresentational. It is also argued that Lopes’s claim that all pictures are belief-independent is unsound. Criticisms of Hopkins’s account of depiction developed in the thesis focus on problems raised by photographic depiction as well as ways in which the ambiguity of the notion of ‘experienced resemblance’ blurs the distinction between misrepresentation and indeterminacy of outline shape. It is also contended that a notion that is fundamental to Hopkins’s account--experienced resemblance in outline shape—leads to problems that are at least as serious as those it would appear to solve. The thesis concludes with a brief assessment of the state of the art of philosophical accounts of depiction. While progress has been made, especially with regard to the clarification of key questions, we still do not have anything like a comprehensive final theory of depiction. (shrink)

Sociologists, philosophers and historians of science are gradually recognizing the importance of visual representation. This is part of a more general movement away from a theory-centric view of science and towards an interest in practical aspects of observation and experimentation. Rather than treating science as a matter of demonstrating the logical connection between theoretical and empirical statements, an increasing number of investigations are examining how scientists compose and use diagrams, graphs, photographs, micrographs, maps, charts, and related visual displays. This paper (...) focuses on diagrams in biology, and tries to demonstrate how diagrams are an integral part of the production of scientific knowledge. In order to disclose some of the distinctive practical and analytical uses of diagrams, the paper contrasts the way diagrams and photographs are used in biological texts. Both diagrams and photographs are shown to be “constructions” that separately and together mediate the investigation of scientific phenoman. (shrink)

ABSTRACT:Are face-to-face perception and picture perception different perceptual phenomena? The question is controversial. On the one hand, philosophers have offered several solid arguments showing that, despite some resemblances, they are quite different perceptual phenomena and that pictures are special objects of perception. On the other hand, neuroscientists routinely use pictures in experimental settings as substitutes for normal objects, and this practice is successful in explaining how the human visual system works. But this seems to imply that face-to-face perception and picture (...) perception are very similar, if not actually the same. How can we decide between these two opposite intuitions? Here I offer a regimentation of the notion of picture perception that can reconcile these two apparently conflicting ideas about pictures. It follows that philosophers and neuroscientists can maintain their respective stances without any theoretical conflict. (shrink)

This dissertation defends the reliability of first-person methods for studying consciousness, and applies first-person experiments to two philosophical problems: the experience of size and of the self. In chapter 1, I discuss the motivations for taking a first-person approach to consciousness, the background assumptions of the dissertation and some methodological preliminaries. In chapter 2, I address the claim that phenomenal judgements are far less reliable than perceptual judgements (Schwitzgebel, 2011). I argue that the main errors and limitations in making phenomenal (...) judgements are due to domain-general factors, which are shared in the formation of perceptual judgements. Phenomenal judgements may still be statistically less reliable than perceptual judgements, though I provide reasons for thinking that Schwitzgebel (2011) overstates the case for statistical unreliability. I also provide criteria for distinguishing between reliable and unreliable phenomenal judgements, hence defending phenomenal judgements against general introspective scepticism. Having identified the main errors in making phenomenal judgements, in chapter 3, I discuss how first-person experiments can be used to control for these errors. I provide examples, and discuss how they overcome attentional and conceptual errors, minimise biases, and exhibit high intersubjective reliability. In chapter 4, I investigate size experience. I use first-person experiments and empirical findings to argue that distant things looking smaller cannot be explained as an awareness of instantiated objective properties (visual angle or retinal image size). I also discuss how an awareness of uninstantiated objective properties cannot adequately account for the phenomenal character of size experience. This provides support for a subjectivist account of variance in size experience. In chapter 5, I investigate the sense of self. I distinguish between a weak sense of self (for-me-ness) and a strong sense of self in which there is a polarity between subject and object. I use first-person experiments from Douglas Harding to demonstrate an explicit strong sense of self, specifically when I point at where others see my face. I also argue that this sense of self is not explained by inference, thoughts, feelings, imagination nor the viewpoint. Rather, it is part of the structure of experience that I seem to be looking from here. Even if there is a sense of self, there may be no self. The question of chapter 6 is whether there can be a direct experience of the self. I argue that to function as a bearer of experience the subject must be single and lack sensory qualities in itself. I use Harding’s first-person experiments to investigate the visual gap where I cannot see my head. I argue that it conforms to the above criteria, and hence is a candidate for being the subject. This finding, in conjunction with the fact that I seem to be looking from the same location, provides prima facie evidence for the reality of the subject. I hold then that contrary to Hume and most philosophers since, that there can be a direct self-experience, if one knows which direction to attend. (shrink)

We discuss how the psycho-historical framework can be profitably applied to artistic production, facilitating a synthesis of perception-based and knowledge-based perspectives on realistic observational drawing. We note that artists' technical knowledge itself constitutes a major component of an artwork's historical context, and that links between artistic practice and psychological theory may yet yield conclusions in line with universalist perspectives.

Philosophers ... always demand that we should think of an eye that is completely unthinkable, an eye turned in no particular direction, in which the active and interpreting forces, through which alone seeing becomes seeing something, are supposed to be lacking; they always demand of the eye an absurdity and a nonsense.

J’argumente que les Quiniens qui sont sceptiques par rapport à la distinction analytique/synthétique devraient aussi être sceptiques quant à la distinction entre conflits verbaux et factuels. Je développe une objection à la distinction entre conflits verbaux et factuels, dérivée des objections à la distinction analytique/synthétique. J’explique ensuite de quoi se compose le scepticisme qui en résulte. En définitive, ces sceptiques devraient reconnaître la différence entre conflits verbaux et factuels, mais pensent que certaines tâches philosophiques ne peuvent être performées.

A commentary on a target article by Alison Gopnik (1993) How we know our minds: the illusion of first-person knowledge of intentionality. Focusing on evidence of how children acquire a theory of mind, this commentary argues that there are internal inconsistencies in theories that both argue for the functional role of conscious experiences and the irreducibility of those experiences to third-person viewable information processing.

This article argues that paintings have a nonconceptual content unlike that of mechanically produced images. The first part of the article outlines an information-theory approach modelled on the camera and based on the idea that pictures convey information about what they depict. Picture structure is conceived of as contentful by virtue of a supposed causal link with what is depicted and as nonconceptual because it is independent of observers’ understanding. The second part introduces an embodied depiction approach based on Merleau-Ponty’s (...) view of style and the act of painting. It is argued that because of bodily mediation the nonconceptual content of paintings cannot be assimilated to the information-theory approach; painted configurations are contentful by virtue of being the product of intelligent activity, but are nonconceptual because they differ from concepts in their representational function.

This article provides a strategic history of the role assigned by modern historians to visual representation in early modern science, an aspect of historiography that is largely ignored in the scholarly literature. Despite the current undervaluation of images and visual reasoning, historians in the 1940s and 1950s who established the 20th century concept of the Scientific Revolution, also assigned a conspicuous role to images, claiming 15th century art as a chapter in the history of science and identifying the first modern (...) scientists in artists such as Brunelleschi and Leonardo. My analysis of the writings that shaped the discourse on visual representation---by giants such as George Sarton, Herbert Butterfield, and Alexandre Koyré---shows that the handful of concepts introduced in these early discussions formed the foundations of the subsequent scholarly approach to early modern scientific images. However, close scrutiny during the 1970s defined these concepts as interesting but not as key elements for the emergence of modern science proposed earlier. The wave of social studies of science in the 1980s further diminished the importance of images, to the point that recent surveys of early modern science neither consider the role of visual representation nor include figures in their narratives. Several recent publications with suggestive titles such as The Power of Images in Early Modern Science promise to recover a significant role for images in the Scientific Revolution. The present inquiry into the earlier discourse seeks to clarify the historiographic framework into which these new efforts fit. (shrink)

It is argued that instrumentalizing the value of art does an injustice to artistic appreciation and provides a hostage to fortune. Whilst aestheticism offers an intellectual bulwark against such an approach, it focuses on what is distinctive of art at the expense of broader artistic values. It is argued that artistic appreciation and creativity involve not just skills but excellences of character. The nature of particular artistic or appreciative virtues and vices are briefly explored, such as snobbery, aestheticism and creativity, (...) in order to motivate a virtue theoretic approach. Artistic virtues are intrinsically valuable excellences of character that enable us to create or appreciate all sorts of things from everyday recipes to the finest achievements of humankind. Such an approach offers a new way to resist the age old temptation to instrumentalize the values of art. (shrink)
