Moreover, though our reason may be to some extent unfit to judge of such matters, the vast importance of the subject seems to demand our coming to some conclusion one way or the other. This is especially the case because important results affecting a man's daily life follow from his deciding that there is a God, and to leave the question undecided is practically the same as deciding that there is not a God. In the same way, if a ship were in danger of sinking, and a steamer also in distress offered to take off the passengers, for one of them to say that he did not know whether it was safer to go in the steamer or not, and would therefore do nothing and stay where he was, would be practically the same as deciding not to go in the steamer. So in the case before us. To refuse to decide the question because of the supposed inadequacy of human reason is practically the same as to deny the existence of God. Still, it may be urged, granting that our reason must decide the question one way or the other, and granting that our reason seems to force us to conclude in the existence of God, are there not great difficulties in honestly believing this conclusion? No doubt there are, and no thoughtful man would think of ignoring them. But after all it is only a choice of difficulties; and, as we have shown, there is _less_ difficulty in believing what we have here maintained than the contrary. It is less difficult, for instance, to believe that the universe had an origin, than to believe that it had not. Similarly as to the existence of God; the theory is not free from difficulties, but, with all its difficulties, it is still by far the most probable theory to explain the origin and present state of the universe. We therefore decide, judging by reason alone (which is the line adopted in this Essay), that the existence of God is _extremely probable_. (_D._) SUMMARY OF ARGUMENT. In conclusion, we will repeat very briefly, the main line of argument thus far. To begin with, in the present universe we observe a succession of changes. If these changes are not recurring, which seems incredible, they must have had a commencement; and this is supported by the theories of Evolution and the Degradation of Energy. Therefore, as this commencement cannot have been a necessity, it must have been due to some _Free Force_. And a Free Force must be a _Supernatural_ Force, since natural forces are not free, but always act according to some fixed law, while the unity of nature points to its being a _Single_ Supernatural Force, which we called the Creator. Next, it follows that the Creator must have foreknown the consequences of His acts, judging by the marks of design which they present. And this conclusion was shown to be not inconsistent with either the process of evolution, or the existence of free will in man or other beings. Hence He must have been a _Personal Being_, possessing both Wisdom to design, and Power to accomplish.
