Thus a second motive for introducing sense-data appeals to the alleged distinction between experiences and the physical objects we perceive. Many of the major subsequent developments in the philosophical treatment of perceptual experience can be seen as attempts to grapple with the tensions in the original notions of sense-data.

Sense-datum theories of perception 33 Adverbial theories of perception `38 Adverbial and sense-datum theories of sensory experience 41 Phenomenalism 43 Perception and the senses 47 2 Memory 55 Other writers put forward the related theory of phenomenalism, a view which was first developed in detail by John Stuart Mill, although it was in fact briefly canvassed by Berkeley (1710, sec 3). All the objections above trace back to deeper tensions arising from three central claims that form part of the original conception of sense-data. When we reflect upon perceptual experience from an external point of view, and think about what is going on when another person is perceiving, then it is natural to conceive of the process of perception as involving a series of distinct, causally related events. In the absence of a positive account, the simple perceiving relation remains obscure, and the grounds for introducing it are unclear (Coates, 1998 and 2007). ... 'The bootstrapping problem is a circularity problem for epistemology. Since I could have a given type of experience – say, of seeming to see a red ball – while hallucinating when no such physical object is present in my surroundings, the common factor cannot include an external physical object. epistemology meaning: 1. the part of philosophy that is about the study of how we know things 2. the part of philosophy…. It is not clear that the parallel between perceptual experience and thought has been successfully made out on the intentionalist view (compare also Martin 2002). Other examples are the image one sees with one’s eyes closed after staring at a Epistemological idealism is a philosophical position, a subcategory of subjectivism, holding that what you know about an object exists only in your mind. Epistemology and Data Science 20th July 2018 in Blog. Naturalized Sense Data. Different lines of thought have been developed, according to which particular problem has been considered most pressing. This core conception of a sense-datum is the idea of an object having real existence, which is related to the subject’s consciousness. 2 Philosophy: Epistemology. Knowledge of sense-data has often been taken to be the foundation upon which all other knowledge of the world is based. In most of these cases we are not usually deceived as to how things really are. We require an account of the difference between the way that perceptual content represents and mere thought represents. Reflection upon common sense, and, in particular, upon scientific extensions of common-sense knowledge, raises complex issues concerning the relation between our experiences and the objective world we perceive. Sellars’ own view was originally formulated in the context of a complex overall account of the nature of language and the way in which we come to refer to mental states such as thought and sensing, and underwent important developments in later work. To say that there is an apple unperceived in the fridge is to say something like: “If I were to open the door of the fridge and if my eyes were open, etc, I would have sense-data of a reddish, apple-like shape, and so forth.” The idea is that any statement that on the surface appears to be about a physical object can, by analogous methods, be translated into a set of statements which refer only to actual and possible sense-data, and do not refer to physical objects. My own view is that something like sense data are necessary to provide a grounding for physics that one might call a metaphysics or in a slightly different context an epistemology for physics. : * What constitutes knowledge? Thus in seeing the apple, I am in fact immediately aware of a visual sense-datum of a certain roughly round shape and red color, which may or may not be identical with some entity in the surrounding world. In double vision, an object appears to be situated in more than one location relative to the subject. Experimental (Positivist), with a more realist ontology (i.e. Provided suitable adjustments were made elsewhere in one’s system, any theory of perception could be adopted. According to this view, acceptance of the sense-data theory amounts to a decision to employ a certain terminology, without deep consequences for metaphysics and epistemology. In order to know anything at all about the table, we must know truths connecting it with things with which we have acquaintance: we must know that 'such-and-such sense-data are caused by a physical object'.
