How are we to know our life's purpose? Can anybody tell us? No; no one can tell us, for life in its very nature is self-revealing, and it is our own fault if we are not open to that revelation which life offers to us; it is not the fault of life. Man is the offspring of nature, therefore his purpose belongs to nature. But the artificiality of life brings obscurity, and this prevents him from receiving that knowledge which is the revelation of his own soul.
