Berkeley is, in fact, inconsistently combining two conflicting lines of thought. He argues, on the one hand, that since there must be some reason for the order in which presentations succeed one another in my mental life, that reason is to be found in a source independent of myself. This source he identifies with God, but, as far as the argument goes, it might equally well have been found, as by Locke, in the original constitution of matter; all that the argument requires is that it shall be placed in something outside the succession of presentations themselves. On the other hand, he also argues that since the existence of the physical world means simply the fact of its being presented to consciousness, when its contents cease to be present to my consciousness they must be present to that of God. And here again the objection might be suggested, that if presence to my own experience, while it lasts, is an adequate account of the _esse_ of a thing, it does not appear why I should recognise the reality of any other experience. If I am to hold that disappearance from my experience does not destroy the reality of anything, I must logically also hold that its being, while I perceive it, is not exhausted by _my_ awareness of it. Its _esse_ cannot be merely _percipi_. The complete solution of Berkeley’s difficulty would be premature at this point of our discussion. But we may at once point out its principal source. It arises from his failure to take adequate account of the purposive aspect of experience. Experience, as we have seen, is not mere awareness of a succession of presented objects, it is awareness of a succession determined by a controlling interest or purpose. The order of my experiences is not something simply given me from without, it is controlled and determined by subjective interest from within. Berkeley, in fact, omits selective attention from his psychological estimate of the contents of the human mind. He forgets that it is the interests for which I take note of facts that in the main determine which facts I shall take note of, an oversight which is the more remarkable, since he expressly lays stress on “activity” as the distinguishing property of “spirits.”[41] When we make good the omission by emphasising the teleological aspect of experience, we see at once that the radical disparity between the relation of the supreme and the subordinate mind to the world of facts disappears. I do not simply receive my presented facts passively in an order determined for me from without by the supreme mind; in virtue of my power of selective attention, on a limited scale, and very imperfectly, I recreate the order of their succession for myself.
