But commonsense is often confined to the manner in which the world is known by the senses, and is blind to the deeper implications of experience. It is imperative that a knowledge of diversity should be rooted in some kind of unity of perception. Plurality is impossible unless there is a witnessing consciousness, different from the pluralistic entities, and connecting them all in a relation of coherence. An extra-cosmic God cannot have any relation to the world, and cannot even fashion it, not even be aware of it. A conscious subject, absolutely independent of its objects, cannot know them, for no relation is possible between differing self-existent principles.
All questions ultimately hinge upon the problems of knowledge.
The structure of consciousness is the crux of philosophical enquiries. With its understanding, all problems get solved, naturally. A thorough-going pluralist cannot defend himself against the charge that even he could not be aware of a plurality of ultimate entities without the aid of a unitary consciousness comprehending them all. His reality hangs loosely in some indeterminable emptiness, call it space or any other thing. The pluralist tries to dovetail artificially several realities into his system, forgetting, however, that in the act of bringing them together to form a consistent whole, he has unconsciously introduced into it a universal synthesising principle made manifest in his own mind.
