specialities. In the very beginning the difficulty was how a mind can apprehend matter which is non-mental. The sensum theory solves the difficulty by postulating an entity which is not matter. But the sensum, being still different form the mind, the difficulty does not seem to disappear. If mind can apprehend the sensum directly in spite of all the differences of the latter from the former, then it can also be held to be apprehending matter equally directly. By calling the sense data psychocerebral the problem of the unity of the psychic and the physical is not solved but is presented in a different way. On the other hand we do not have any evidence to prove the independent existence of the sensum except the pseudonecessity created by the sensum theory. By holding that the sense data are different for each individual an indirect attempt is made to make them mental, for only the mental can be said to belong singularly to the mind in the true sense of the term. On the other hand-G.E. Moore questions the independence of the sense datum from the objects. He says: “If what was seen were merely coloure sensation and what was touched were only a tactual sensation and both were merely mental or physiological states, the one could not be identified with the other. The sense data are, therefore, somehow, connected with the physical òbject."1 Thus the identity of the sense datum is required to be reduced to mind on one hand and to the objects on the other. The theory does not successfully lead to an independent identity of the sensa. A right implicaton of the sensum theory may be that the precess of knowledge is bipolar. It admits of contributions made by the subject and the object both. In the absence of either of them knowledge will not be possible.
