180:. From a subjective experience of perceiving something, it is theoretically impossible to distinguish perceiving something which exists independently of oneself from an hallucination or mirage. Thus, we do not have any direct access to the outside world that would allow us to reliably distinguish it from an illusion that caused identical experiences. Since (the argument claims) we must have direct access to some specific experiential entity in order to have the percepts that we do, and since this entity is not identical to the real object itself, there must be some sort of internal mental entity somehow correlated to the real world, about which we afterwards have perceptions, make judgments, etc. This entity is a sense-datum.

Thus the criticism that sense data cannot really be red is made from a position of presupposition inconsistent with a theory of sense dataâso it is bound to seem to make the theory seem wrong. More recent opposition to the existence of sense data appears to be simply regression to
300:. Much of the early criticism may arise from a claim about sense data that was held by philosophers such as A. J. Ayer. This was that sense data really do have the properties they appear to have. Thus, in this account of sense data, the sense data that are responsible for the experience of a red tomato really "are red".

This may seem implausible, since there is nothing red in a brain to act as a sense datum. However, it is perfectly consistentâin the sense that the data "are red" when experienced directly, even though the physical processes of perception may not appear red if they were experienced in a contrived and

Sense data are often placed in a time and/or causality series, such that they occur after the potential unreliability of our perceptual systems yet before the possibility of error during higher-level conceptual analysis and are thus incorrigible.

On some theories, the tomato itself is not red except in the eyes of a red-seeing being. Thus when one says that a neural state is or is not 'red' without referring the judgement of redness to the owner of the neurons concerned, there is an assumption that things can have innate appearances without

Abstract sense data is sense data without human judgement, sense data without human conception and yet evident to the senses, found in sense experience. As opposed to; imaginary sense data which is more like a quasi substance and does not really exist; Imaginary sense data is abstract sense data as

When we twist a coin it 'appears' to us as elliptical. This elliptical 'appearance' cannot be identical with the coin (for the coin is perfectly round), and is therefore a sense datum, which somehow represents the round coin to us.
