A first cause, we have already seen, must be a free cause. It cannot have been itself caused. It is absurd to look for it among effects. But we never get out of the sphere of effects until we enter that of free agency; until we emerge from the natural into the spiritual; until we leave matter and reach mind. The first cause must, indeed, be in--all through--the universe; but it must also be out of the universe, anterior to, and above the universe. The idea of cause is a delusion--the search for causes an inexplicable folly--if there be no first cause, and if that first cause be not a free cause, a Will, a Spirit, a Person. Those who object to the causation argument, that it does not take us beyond the world--does not lead us up to a personal cause of the world--have failed to apprehend what causation signifies. Secondary causes may not be true causes, and yet reason be trustworthy, for there is that behind them on which it can fall back; but if there be no first cause, or if the first cause be not free, reason is throughout a lie. Reason, if honest and consistent, cannot in its pursuit of causes stop short of a rational will. That alone answers to and satisfies its idea of a cause. The most rapid glance at the universe powerfully confirms the conclusion that its first cause can only be a Mind, a Reason. The universe is a universe; that is to say, it is a whole, a unity, a system. The first cause of it, therefore, in creating and sustaining it, must comprehend, act on, and guide it as a systematic whole; must have created all things with reference to each other; and must continually direct them towards a preconceived goal. The complex and harmonious constitution of the universe is the expression of a Divine Idea, of a Creative Reason. This thought brings me to my next argument and next lecture.[20] [20] See Appendix XII. LECTURE V. THE ARGUMENT FROM ORDER. I.
