Now, is it not obvious that while the external results of wisdom are great and marked, this inward result, which is the spring of them all, is more blessed than any? The laws which govern the universe are the laws of God. The Stoic philosophy demanded a life according to Nature. That is not enough, for by Nature is meant God's will for the inanimate or non-moral creation. Where there is freedom of the will, existence must not be "according to Nature," but according to God; that is to say, life must be lived in obedience to God's laws for human life. The inorganic world moves in ordered response to God's will. We, as men, have to choose; we have to discover; we have to interpret. Woe to us if we choose amiss, for then we are undone. Woe to us if we do not understand, but in a brutish way follow the ordinances of death instead of the way of life! Now, the supreme bliss of the heavenly wisdom is that it leads us into this detailed obedience to the law which is our life; it sets us under the immediate and unbroken control of God. Well may it be said, "Happy is the man that findeth wisdom, and the man that getteth understanding. For the merchandise of it is better than the merchandise of silver, and the gain thereof than fine gold. She is more precious than rubies."[46] And yet rubies are very precious. I learn that the valley in Burmah where the most perfect rubies in the world are found is situated four thousand five hundred feet above the sea level, in a range of mountainous spurs about eighty miles due north of Mandalay; but owing to the difficult nature of the intervening ground, the valley can only be reached by a circuitous journey of some two hundred miles, which winds through malarious jungles and over arduous mountain passes. An eminent jewellers' firm is about to explore the Valley of Rubies, though it is quite uncertain whether the stones may not be exhausted. Wisdom is "more precious than _rubies_, and none of the things thou canst desire are to be compared unto her."
