The question of whether conscious experience has any functional purpose depends on a more fundamental issue concerning the nature of conscious experience. In particular, whether the world of experience is the external world itself, as suggested by direct realism, or whether it is merely a virtual- reality replica of that world in an internal representation, as in indirect realism, or representationalism. There is an epistemological problem with the notion of direct realism, for we cannot be consciously aware of objects beyond the sensory surface. Therefore the world of experience can only be an internal replica of the external world. This in turn validates a phenomenological approach to studying the nature of the perceptual representation in the brain. Phenomenology reveals that the representational strategy employed in the brain is an analogical one, in which objects are represented in the brain by constructing full spatial replicas of those objects in an internal representation.

James Mensch, 1970 No philosophical activity is immune from the question of its grounds, its origin, its arche. Philosophizing is not carried out in a vacuum. The philosopher in any inclusive view cannot be seen to be a being set apart from the world about which he philosophizes. He is distinct neither from the world nor its history considered in its totality. A truth so obvious requires only a brief meditative reflection: A philosopher sits writing at his desk. Without even raising his head, he directs his glance about him. What is the reality that appears? The most immediate objects of his perception, the pen, the paper, the desk, the printed book which lies open before him, even the words which he writes, all have a historical character. Paper, pen, desk and book, these objects are all the products of a historically defined type of work. They are the creations, the phenomenal manifestations of modern technological work.1 Even the words which he writes presuppose a history, a personal history insofar as these words are not empty signs but rather consist in meaningfully arranged characters, which he has learned to write and which someone has, therefore,. taught him to write. The meaning of words has to be won through a continuing encounter with reality, an encounter both personal and historically transcendent of the individual person, an encounter which is never the same, never repeated in an identical fashion. What is the reality that is present to him now, what is the totality of all that is now confronting us as beginning philosophers? As the above observations point out, the briefest of reflections leads us to the questions of the history and genesis of the things that confront us. But what is the condition of this confrontation, this encounter between the philosophizing subject and the world which he wishes to comprehend? Aristotle noted that all men naturally desire to know. Why? Our question is actually, “How does Being come to know itself?” This, of course, can be....

To adopt a first-person perspective on consciousness is typically understood as a matter of inwardly engaging one's awareness in such a way as to make one's conscious states and their properties into objects of awareness. When awareness is thus inwardly engaged, experience functions as both act and object of awareness. As objects of awareness, an experience-token and its various properties are items of which a subject is aware. As an act of awareness, an experience-token is that in virtue of which items - in this case, other experience-tokens and their properties - can appear, to a subject, as objects of awareness. The precise nature of the relation between experience functioning as act and as object is a matter of dispute. However, two broad possibilities can be distinguished: (1) as acts of awareness, experiences reveal other experiences to subjects by way of a form of direct, unmediated, acquaintance, (2) as acts of awareness experiences reveal other experiences to subjects by way of modes of presentation of those experiences. I shall argue against (1). Possibility (2), I shall argue, entails a form of representationalism about experiences: experiences are defined by their representational role. However, (2) also yields a crucial but largely neglected consequence of representationalism: necessarily, in any given experience, there is an aspect of this experience that must be understood in terms of its representational role but cannot be understood in terms of its representational content. I shall call this the ineliminable intentional core of the experience. The ineliminable intentional core of the experience is, necessarily, not an object of inwardly engaged awareness. This entails a significant revision in the way we think about the concept of the first-person perspective, and of what it is to study consciousness from the inside.

The historically most central epistemological issue concerning perception, to which this article will be almost entirely devoted, is whether and how beliefs about physical objects and about the physical world generally can be justified or warranted on the basis of sensory or perceptual experience—where it is internalist justification, roughly having a reason to think that the belief in question is true, that is mainly in question (see the entry justification, epistemic: internalist vs. externalist conceptions of). This issue, commonly referred to as “the problem of the external world,” divides into two closely related sub-issues, which correspond to the first two main sections below. The first of these issues has to do with the nature of sensory experience and its relation to the physical world; it is typically (though as we shall see not altogether perspicuously) formulated as the question of what are the immediate objects of awareness in sensory experience or, in a variant but essentially equivalent terminology, of what is given in such experience. Perhaps the most historically standard, though not currently the most popular answer to this question has been that it is sense-data (private, non-physical entities that actually have the immediately experienced sensory qualities) that are the immediate objects of awareness or that are given. The second issue has to do with the way in which beliefs about the physical world are justified on the basis of such sensory experience. If it is concluded that physical objects are not themselves given, the two main answers to this question are representationalism or indirect realism (the view that the immediate objects of experience represent or depict physical objects in a way that allows one to infer justifiably from such experience to the existence of the corresponding “external” objects) and phenomenalism (the view..

Consider the following well-worn example, first put forward by Fred Dretske. You’re at the zoo, and in the pen in front of you is a striped horse-like animal. The sign on the pen says “Zebra.” Assuming that animal really is a zebra, it would seem that your evidence is perfectly adequate to enable you to know that it’s a zebra. So you know.

It is argued that the disciplinary identity of anatomy and physiology before 1800 are unknown to us due to the subsequent creation, success and historiographical dominance of a different discipline-experimental physiology. The first of these two papers deals with the identity of physiology from its revival in the 1530s, and demonstrates that it was a theoretical, not an experimental, discipline, achieved with the mind and the pen, not the hand and the knife. The physiological work of Jean Fernel, Albrecht von Haller and others is explored to prove this point. In conclusion this old physiological tradition is compared to the new experimental physiology, as practised by Francois Magendie and Pierre Flourens.

We perceive things in the external world as spatially located both with respect to each other and to ourselves, such that they are in principle accessible from where we seem to be. I hear the door bang behind me; I feel the pen on the desk over to my right; and I see you walking beneath the line of pictures, from left to right in front of me. By displaying these spatial relations between its objects and us, the perceivers, perception places us in the perceived world: our world and the world we perceive are one. Clearly this is not achieved by our continually perceiving ourselves along with the things around us, and thus recovering our position with respect to them. Indeed I shall argue that there are serious difficulties with the suggestion that this might be the basic mechanism for perceptual self- location. Furthermore, I shall argue that our existence as an element of the objective order cannot be inferred from the raw given in sense perception. Hence it cannot even be on the right lines as an answer to the question 'What is it for perception to represent its objects as environmental to the subject?', that it should present these objects, along with the perceiving subject himself, or along with something from which his existence in the perceived world could be deduced, in the very same frame so to speak. Nevertheless it yields him an awareness of himself as there in the wings of that scene, genuinely located with respect to the action, yet somehow not normally quite getting onto the stage. And I shall argue here, that perceptual contents succeed in being self-locating in this way in..

I argue that transcendental idealism can be understood as a coherent and plausible account of experience. I begin by proposing an interpretation of the claim that we know only appearances that does not imply that the objects of experience are anything other than independently real objects. As I understand it, the claim here is abouthow objects appear to us, and not aboutwhat objects appear to us. After this, I offer a version of a correspondence account of veridical experience, in virtue of which these independent entities can satisfy the contents of our experiences. Specifically, I claim that veridical experience can be construed as a kind of map of reality in itself, and that these independent entities satisfy the contents of our experiences when they are, given the proper method of projection, the objects mapped by those experiences.

To what extent is the external world the way that it appears to us in perceptual experience? This perennial question in philosophy is no doubt ambiguous in many ways. For example, it might be taken as equivalent to the question of whether or not the external world is the way that it appears to be? This is a question about the epistemology of perception: Are our perceptual experiences by and large veridical representations of the external world? Alternatively, the question might be taken as asking whether or not the external world is like its ways of appearing to us, where the expression “ways of appearing” is intended to pick out aspects of our perceptual experiences themselves. This is a metaphysical version of the question of the relationship between appearance and reality: What is the relationship between the phenomenal features that characterize perceptual experience, on the one hand, and the mind-independent features of the external objects of perception, on the other? There are some philosophers who might resist distinguishing between these two questions. For them, “ways of appearing” in the phenomenal sense just are the ways that things appear to be (let’s call the latter the “intentional sense” of “ways of appearing”).1 That is, the phenomenal character of an experience is nothing over and above its representational content. Phenomenal properties are represented properties—the properties that an experience attributes to the external objects of perception. The question of whether or not phenomenal properties can be identified with the represented properties of an experience mirrors traditional questions in the philosophy of perception. If they can be identified with each other, then in veridical perception we might be said to “directly grasp” features of the external world through perception. The properties that are present to the mind are the very same properties that belong to the external objects of perception. Such a view affords....
