Moreover, each new set of effects becomes the cause of still other effects. Thus, in our universe, as we conceive it to be constituted, increasing complexity would seem to be the great resultant law of the operation of universal forces. This is the great law of nature, to which every living thing must conform, if it is to be in harmony with all other things. In a universe controlled by intelligence, it is only natural to find everything within the universe moving along towards one increasing purpose. As new light has come to man, the certainty of this law as a controlling one, has become more and more emphatic. **Man and the Great Law.** The law of increasing complexity is fundamental. Since man is constantly being acted upon and acting upon matter and energy, he must himself be brought under the subjection of the great law. That is, under normal conditions, he will increase in complexity. As man observes phenomena and reasons upon them and applies them he grows in knowledge. Where he formerly had one fact to use, he now has many. This is the essence of his complexity. A carpenter with one tool does less and poorer work than does one with a full kit of modern tools. Likewise, man, as he gathers experience, becomes more powerful in using the forces of nature in the accomplishment of his purposes. With this thought in mind the great law becomes a law of increasing power, of progressive mastery over the universe. For that reason, the law expressing the resultant of the activities of universal forces is often called the law of progression. The degree of man's growth or progression will depend upon the degree his will is exercised, intelligently, upon the things about him. It is even conceivable that by the misuse of will, man may lose some of his acquired powers. In any case, the operation of the will, under normal conditions, adds power to man; and by the use of the intelligent will in a world of matter and energy, the increasingly complex man grows in power and strength towards perfection, in an increasingly interesting world. Those who do not conform to the law of progression are abnormal and do not exert their powers, to the requisite degree, in the right direction. Nature is inexhaustible in the possible number of inter-relations among matter, energy and intelligence. It follows, therefore, that man will forever be able to add knowledge unto knowledge, power unto power, or progress unto progress. This law of progression is the great law of the universe, without beginning and without end, to which all other laws contribute. By adherence to this law the willing, intelligent beings have risen to their present splendid state of manhood, and by further compliance with this law they will advance to a future Godlike state of perfection. The supreme intelligence and perfected will of the universe, God, has attained His position by an obedient recognition of the conditions of the law of progression.
