Sense-perception is a hackneyed topic, and I must therefore begin by craving your indulgence. I was moved to make it the subject of this evening's lecture by the fact that I have lately been reading the book in which the most important of the late Professor Prichard's scattered writings on Sense-perception have been collected by Sir W. D. Ross. Like everything that Prichard wrote, these essays are extremely acute, transparently honest, and admirably thorough. I shall not (...) attempt here either to expound or to criticize Prichard, but he may be taken to be hovering, perhaps somewhat disapprovingly, in the background during the lecture. (shrink)

'Sense perception in current process thought' was the topic of a workshop organized by the 'Whitehead Psychology Nexus' (for more information see below) at Fontareches in spring 2003. This and earlier Fontareches meetings can be characterized by just a few elements: non-dogmatism, interdisciplinarity and overlapping approaches. Although the convergence point is Whitehead's philosophy, this is intended in the sense of an 'eschaton' rather than a 'telos'. The vivid discussions, occurring in a very thoughtful, yet relaxed, atmosphere in (...) the small village of Fontareches in Southern France, have amply testified for the promising paths and synergies that can emerge in such an environment. This year, the core intention was to examine relations between Whitehead's theory of perception and contemporary psychology. The individual contributions can be sorted into the three areas of philosophy, cognitive science, and mental health/psychoanalysis. Unsurprisingly, the question of temporality was addressed -- explicitly or implicitly -- in most of the papers. (shrink)

This chapter considers an element of Plato’s account of sense perception. In particular, it poses the question of how widely Plato construes the content of the perceptual capacity. It argues that, based on what Plato says in the Theaetetus and the Timaeus there is good reason to think that sense perception is limited to just those simple sense qualities that are made available to the soul by the individual sensory powers, i.e., colors by sight, sounds (...) by hearing, etc. This, however, raises the question of how, according to Plato, the soul becomes aware of features that are often thought to be perceptible through more than one sensory power: features like shape, motion, rest, number, etc. The chapter addresses this issue by arguing that the awareness of these features requires the co-operation of sense perception with additional capacities of the soul, in particular the capacity for reflective thought; for recognizing these features requires the deployment of basic concepts like sameness and difference. An upshot of the position defended in this chapter is that, if correct, it indicates that, for Plato, rational capacities may be more widely distributed than is often thought. (shrink)

Chapter INTRODUCTION i. The Problem Why suppose that sense perception is, by and large, an accurate source of information about the physical environment? ...

This chapter compares rationalist theories of sense perception to previously held theories of perception (especially of vision) and examines rationalist accounts of sensory qualities and sensory representation, of the role of the sense-based passions in guiding behavior, of the epistemological benefits and dangers of sense perception, and of mind–body relations. Each section begins with Descartes, the first major rationalist of the seventeenth century. The other major rationalists, Malebranche, Spinoza, and Leibniz, and also lesser known (...) figures such as Pierre Regis, Jacques Rohault, and Antoine Le Grand, were well acquainted with Descartes' work. Indeed, the first three were each deeply influenced by Descartes in their early years before developing their own philosophical systems, and the latter three were all advocates of Descartes' philosophy (perhaps with slight revision). Each of the major rationalists, while sharing some positions in common, developed a distinctive metaphysics of perception and of the mind–body relation. Earlier sections chart these differences and a final section sums up common features and touches on the continuing significance of their views. (shrink)

This paper discusses the role of innate concepts derived from Intellect in Plotinus’ account of cognition of the sensible realm. Several passages have been claimed as evidence for such innateness, but an analysis of them shows that they do not support this claim. It is tentatively suggested that, nevertheless, some very general concepts such as difference, sameness and being are integral to the faculty of sense and play a crucial role in concept formation. It is further argued that reasoning (...) about the sensible realm takes place to a large extent without the involvement of the higher realms of Plotinus’ hierarchy of being. Clearly, however, for value concepts such as those of goodness, justice and beauty human beings are dependent upon an illumination from Intellect. (shrink)

In this essay I explore the controversial issue of sense perception in the Zhuangzi 莊子. Although scholars have not explicitly addressed this aspect of the Chinese text, a common assumption is that the Zhuangzi proposes a mysticism that undermines sense perception in favour of a transcendent self. After an overview of this interpretation, and after analysing some key passages of the text that deal with heart fasting (xinzhai 心齋), sitting and forgetting (zuowang 坐忘) and skill mastery, (...) I demonstrate that some interpreters of the Zhuangzi read the text as if it has a metaphysical bent, recommending that sense perception be transcended as a prerequisite to perfection. In contrast, my thesis is that the text does not propose a withdrawal from the senses and from the world, but rather warns about the danger of abiding to doctrinal knowledge, which has the consequence of a person losing their responsive awareness. Indeed, in the Zhuangzi, sense perception is not an impediment on the way to a supersensible reality, but an integral part of one’s own being in the world. Through my analysis, I object to the idea that the Zhuangzi proposes a mystical union with something not immediately available, which moreover needs to be achieved by transcending the lived world that is encountered through sense perception. My view is that such a move not only postulates union with a transcendent entity, it also forces a dualism between a person’s capacities. This is problematic because the Zhuangzi does not point to another world – in a two worlds theory – where one must ideally attain the condition of a transcendent self. On the contrary, in rejecting a univocal ethos, the text suggests one should keep responding to changing circumstances without turning one’s perceptual awareness into entrenched habits. Thus, the Zhuangzi shows how sense perception should be seen, not as a “problem” but as an ethical possibility through which the univocity of doctrinal knowledge can be undermined. (shrink)

Originally published in 1964. In four essays, Professor Mandelbaum challenges some of the most common assumptions of contemporary epistemology. Through historical analyses and critical argument, he attempts to show that one cannot successfully sever the connections between philosophic and scientific accounts of sense perception. While each essay is independent of the others, and the argument of each must therefore be judged on its own merits, one theme is common to all: that critical realism, as Mandelbaum calls it, is (...) a viable epistemological position, even though some schools of thought hold it in low esteem.

Several studies have approached sense perception in the encyclopaedias of Thomas of Cantimpré, Bartholomew the Englishman, and Vincent of Beauvais. A comparative analysis of these encyclopaedias shows that all of them arrange sense perception in accordance with the expositions on the soul and with human and animal anatomy. Yet there are significant differences in how they treat the objects of sensation: Thomas does not refer to them at all, Bartholomew considers them to be “accidents,” and Vincent (...) deals with them separately when discussing the features of the sensible world. These differences, I argue, respond to two different readings of Aristotle. (shrink)

Several studies have approached sense perception in the encyclopaedias of Thomas of Cantimpré, Bartholomew the Englishman and Vincent of Beauvais. Yet a systematic overview and comparison of the arrangement of sense perception in these encyclopaedias is still lacking. The overview offered here shows that all encyclopaedias place sense perception beside expositions on psychology and anatomy. There are, however, significant differences in how they treat the objects of sensation. In the case of Bartholomew and Vincent, (...) I argue, these differences reflect two different readings of Aristotle. (shrink)

RésuméDans cet article, je soutiendrai que divers philosophes du kalām s'accordent à dire que la perception sensorielle dépasse les processus physiques dans les organes sensoriels. Il peut se passer quelque chose dans nos yeux lorsque nous voyons une pomme rouge, mais voir une pomme rouge ne s'y réduit pas. Nous verrons que certains philosophes du kalām soutiennent que la perception sensorielle est semblable à une prise de conscience ou à une conscience de l'objet de la perception, et (...) qu'elle est, par conséquent, distincte du processus physique dans les organes sensoriels. Un groupe ira jusqu’à accepter que la perception sensorielle ne dépend même d'aucun processus physique dans le corps. Un autre groupe acceptera que la perception sensorielle présuppose diverses conditions physiques, mais il considérera néanmoins la perception sensorielle comme quelque chose de distinct de l'occurrence de ces conditions. Je suggère que ces théories non réductionnistes de la perception sensorielle sont la raison pour laquelle les philosophes arabo-islamiques, à partir du XIe siècle, rejettent systématiquement la théorie aristotélico-avicennienne de la perception sensorielle.

There is more evidence for Empedocles than for any early Greek philosopher before Democritus, yet the details of his philosophy remain controversial and often hopelessly obscure. Jaeger called Empedocles a ‘philosophical centaur’, which aptly sums up the seeming disparity between the and the There is no agreement about the famous simile to illustrate respiration, generally known as the Clepsydra, and the stages and nature of the cosmic cycle continue to be disputed. Perhaps we can never be certain about these aspects (...) of Empedocles' thought, for the evidence fails at every crucial point and the imaginative reconstructions which have to serve are unlikely to win universal acceptance. It may then appear hazardous to discuss the fragments concerned with thinking and sense-perception, for these too are riddled with problems. I do so prompted partly by the timely reprint of J. I. Beare's book, Greek Theories of Elementary Cognition, and also because this feature of Empedocles has been touched on by modern scholars but not studied in any detail. At the same time the significance of the is greatly affected by how we interpret the theory of sense-perception and thinking. (shrink)

This book is a philosophical analysis of Plotinus' views on sense-perception. It aims to show how his thoughts were both original and a development of the ideas of his predecessors, in particular those of Plato, Aristotle and the Peripatetics. Special attention is paid to Plotinus' dualism with respect to soul and body and its implications for his views on the senses. The author combines a historical approach to his subject, setting Plotinus' thought in the context of thinkers who (...) preceded and succeeded him, with a proper analysis of his ideas and, where appropriate, of those from which they derived.

The Buridanian view of the concrete cognition as the general characteristics of sense perception was adopted by Jodocus Trutfetter and Bartholomaeus Arnoldi of Usingen. This theory was not accepted merely on the basis of authority, but it was argued against the competing view, which appeared as legitimate inside the late medieval school of via moderna.

Metaphysical and epistemological commitments seem to determine the course of research in the field of logic as well as its theoretical interpretation. What we take the objects of logical investigation to be determines our views on how they are to be known, and our view of the possible types of knowledge in turn places restrictions on what kinds of things those objects could be. Perhaps it is true that logical studies can be pursued to great lengths without indulging in general (...) declarations about the nature of reality or of human knowledge. But to say this is very far from admitting the possibility of “logic without ontology.” The thoughtful beginning student in logic quickly wants to know what it is he or she is really studying and what, precisely, it has to do with the real worlds. The slightest philosophical stimulation will lead him or her, further, to ask about the evidence supporting the various sorts of claims made as the course progresses, and about the methodology of logic from a scientific point of view. Rarely is any answer given to such questions, much less a reasonable and well elaborated one. Questions of this type are usually discouraged and avoided by text books and instructors, and there may even be some suggestion that to ask them evidences confusion and stupidity. But when they are pressed it turns out that logic as a field of knowledge and inquiry remains in chaos at its philosophical foundations. I mean by this that the leading investigators cannot agree—indeed, they disagree in dimensions categorial—concerning what the subject of logical knowledge is, and concerning the modes of logical knowledge.

There can be little disagreement about whether ideas of sense perception are, for Spinoza, to be classed as passions or actions—the former is obviously the correct answer. All this, however, does not mean that sense perception would be, for Spinoza, completely passive. In this essay I argue argues that there is in the Ethics an elaborate—and to my knowledge previously unacknowledged—line of reasoning according to which sense perception of finite things never fails to contain (...) a definite active component. This argument for activity in sense perception consists of two main parts: first, that ideas we form through sense perception have something adequate in them; second, that the adequate component is actively brought about. Discerning this line of thought connects to—and sheds some new light on—Spinoza’s general way of understanding ideas as entities involving activity. (shrink)

In the debate over the existence of composite objects, it is sometimes suggested that perceptual evidence justifies belief in composite objects. But it is almost never suggested that we are perceptually justified in believing in composite objects on the basis of the fact that the phenomenology of our perceptual experiences enables us to discriminate between situations where there are composite objects and situations where there are merely simples arranged composite object-wise. But while the thought that the phenomenology of our perceptual (...) experiences cannot enable us to discriminate between situations where there are composite objects and situations where there are merely simples arranged composite object-wise is commonly taken for granted, it requires some defence, both in light of its importance in shaping the debate and in light of its recently coming under attack by a prominent philosopher of perception. In this paper, I offer such a defence. (shrink)

What are phenomenal qualities, the qualities of conscious experiences? Are phenomenal qualities subjective, belonging to inner mental episodes of some kind, or should they be seen as objective, belonging in some way to the physical things in the world around us? Are they physical properties at all? And to what extent do experiences represent the things around us, or the states of our own bodies? Fourteen original papers, written by a team of distinguished philosophers and psychologists, explore the ways in (...) which phenomenal qualities fit in with our understanding of mind and reality. This volume offers an indispensable resource for anyone wishing to understand the nature of conscious experience. (shrink)

This article discusses the theories of perception of Robert Kilwardby and Peter of John Olivi. Our aim is to show how in challenging certain assumptions of medieval Aristotelian theories of perception they drew on Augustine and argued for the active nature of the soul in sense perception. For both Kilwardby and Olivi, the soul is not passive with respect to perceived objects; rather, it causes its own cognitive acts with respect to external objects and thus allows (...) the subject to perceive them. We also show that Kilwardby and Olivi differ substantially regarding where the activity of the soul is directed to and the role of the sensible species in the process, and we demonstrate that there are similarities between their ideas of intentionality and the attention of the soul towards the corporeal world.
