The renowned scientist, Sir Arthur Eddington, says that our true personality and consciousness are not parts of observed phenomena but belong to the background of phenomena. According to him, our deeper feelings are not of ourselves alone, but are glimpses of a reality transcending the narrow limits of one particular consciousness. The stuff of the world, to him, is finally a limitless mind or consciousness. We know a particular world because it is that alone with which the consciousness interacts. He gives matter, in the end, the character of knowability, and regards it as grafted on a spiritual substratum.
Reality is fundamentally spiritual, is general consciousness .
And he further makes the discovery that, where science has progressed the farthest, the mind has but regained from Nature that which the mind has put into Nature. Here, Eddington obviously rises from physics and enters the realm of philosophy and mysticism. This is what all men of deep reflective thinking are in the end obliged to do. Whitehead would receive nothing into the physical scheme that is not discoverable as an element in subjective experience. He feels that the poets are entirely mistaken and that they should address their lyrics to themselves and congratulate themselves on the excellency of the human mind.
