Unconsciousness is no bar to livingness. Our conscious actions are a drop in the sea as compared with our unconscious ones. Could we know all the life that is in us by way of circulation, nutrition, breathing, waste and repair, we should learn what an infinitesimally small part consciousness plays in our present existence; yet our unconscious life is as truly life as our conscious life, and though it is unconscious to itself it emerges into an indirect and vicarious consciousness in our other and conscious self, which exists but in virtue of our unconscious self. So we have also a vicarious consciousness in others. The unconscious life of those that have gone before us has in great part moulded us into such men and women as we are, and our own unconscious lives will in like manner have a vicarious consciousness in others, though we be dead enough to it in ourselves.
Samuel Butler, in 'How to Make the Best of Life'
