Abstract

When I perceive a physical object I am directly aware of something. This something may be called a sense?datum, leaving the question open whether it is indeed the physical object itself. Still, this question must be asked. It seems impossible that the sense?datum can be identical with the physical object for we do not always say we have different physical objects when we say we have different sense?data. On the other hand, the plain man does not think of the physical object as something other than the sense?datum. It is suggested that the plain man regards the sense?datum as in a sense identical with the physical object he is perceiving. But it is a peculiar sense of ?identity? which is in question, one which does not conform to the rules logicians lay down for this word
