Naturally, the original spirit, possessing, with all other attributes of intelligence, the power of will, exercised that will upon the contents of the universe. The exercise of the will upon the matter and energy within reach, enabled the intelligent beings, little by little, to acquire power. By the use of his will upon the contents of the universe, man must have become what he now is. **Value of the Will.** The above doctrine involves the idea of self-effort. It is only when the will is exercised in a certain direction that the support of other forces may be invited so that progress in that direction may be accelerated. From the beginning, the deliberate use of the will has moved personal beings onward; and in this latest day of our existence, it is the will that moves men into greater lives. Undoubtedly, the will of man will determine the completion of the structure built through all ages into a perfected man. The Gospel, resting upon eternal, indestructible principles, maintains the living supremacy of the will of man. The culture, training and use of the will, for good or for evil, determine primarily the direction of an individual life. CHAPTER 5. THE GREAT LAW. The innumerable interactions of the matter, energy and intelligences of the universe, must be held together by some great law. This universal law to which all lesser laws contribute, must be of real concern to the man who seeks a true philosophy of life. **Increasing Complexity of the Universe.** It has already been said that a universe controlled by intelligence and under the reign of the law of cause and effect cannot be conceived to be in confusion. Man is absolutely certain, if his knowledge is rational, that, whether it be yesterday, today or tomorrow, the same act, under the same conditions, will produce the same result. Under a set of given conditions, a ray of sunshine passed through a glass prism will always be broken into the same spectrum, or a straight stick standing in water will always appear crooked. Whether in the physical, mental or moral world, the law of cause and effect reigns supreme. Quiescence in the universe can not be conceived, for then there would be no universe. Constant action or movement characterizes the universe. The multiplicity of actions upon each other, of the various forms of matter, energy and intelligence, composing the universe, must cause an equal multiplicity of effects. Moreover, increasing intelligent wills, acting upon matter and energy, must and do produce an increasing series of reactions among the forces of the universe.
