We might also suitably call it Presentationism, if the name were not already appropriated in a different sense as distinctive of certain psychological theories. The English reader will find a confused but typical exposition of Subjectivism in the opening chapters of Prof. Karl Pearson’s _Grammar of Science_. Subjectivist writers usually call themselves “idealists,” and regard themselves as disciples of Berkeley and Hume. Berkeley was, however, a subjectivist, if at all, only in respect to the physical world, while Hume’s conclusions are purely sceptical. The reader of Prof. Pearson must carefully observe that the “descriptive” theory of physical science has no special connection with Subjectivism, and is, in fact, held by philosophers like Profs. Ward and Royce, who are not subjectivists. Footnote 50: On the existence of my fellow-men as the one real proof of the objective existence of the physical world, see Royce, _Studies in Good and Evil_, essay on “Nature, Consciousness, and Self-Consciousness,” and “Mind and Nature,” by the present writer, in _International Journal of Ethics_ for October 1902. In the latter essay I have, I think, sufficiently exposed the flimsy reasoning by which subjectivists attempt to justify belief in the existence of other human beings from the subjectivist point of view. Footnote 51: The self-knowledge which is a fact in real life, as distinguished from the fictitious self-consciousness of some psychologists, is quite a different thing and involves two distinct acts of cognition: (1) the awareness of certain objects of cognition, and (2) the recognition of those objects as in some way qualifying my “self.” And the “self” which I recognise as thus qualified is again no immediate datum of experience, but a largely hypothetical intellectual construction, as we shall have opportunity to see later on. This is perhaps the place to add the further remark, that if we would be rigidly accurate in psychological terminology, we ought to banish the very expression “consciousness” or “state of consciousness” from our language. What are really given in experience are attentive processes with a certain common character. We abstract this character and give it the name of “consciousness,” and then fall into the blunder of calling the concrete processes “states” or “modifications” of this abstraction, just as in dealing with physical things we first make abstraction of their common properties, under the name of “matter,” and then talk as if the things themselves were “forms” of “matter”. _Properly speaking, there are physical things and there are minds, but there are no such things in the actual world as “matter” and “consciousness,”_ and we do well to avoid using the words where we can help it.
