1. We have attempted to show that if the discoveries made by the Telescope should excite in any one's mind, difficulties respecting those doctrines of Natural Religion,--the adequacy of the Creator to the support and guardianship of all the animal life which may exist in the universe,--the discoveries of the Microscope may remove such difficulties; but we have remarked also, that the train of thought which leads men to dwell upon such difficulties does not seem to be common. But what will be the train of thought to which we shall be led, if we suppose that there are, on other planets, and in other systems, not animals only, living things, which, however different from the animals of this earth, are yet in some way analogous to them, according to the difference of circumstances; but also creatures analogous to man;--intellectual creatures, living, we must suppose, under a moral law, responsible for transgression, the subjects of a Providential Government? If we suppose that, in the other planets of our solar systems, and of other systems, there are creatures of such a kind, and under such conditions as these, how far will the religious opinions which we had previously entertained be disturbed or modified? Will any new difficulty be introduced into our views of the government of the world by such a supposition? 2. I have spoken of man as an Intellectual Creature; meaning thereby that he has a Mind;--powers of thought, by which he can contemplate the relations and properties of things in a general and abstract form; and among other relations, moral relations, the distinction of _right_ and _wrong_ in his actions. Those powers of thought lead him to think of a Creator and Ordainer of all things; and his perception of right and wrong leads him to regard this Creator as also the Governor and Judge of his creatures. The operation of his mind directs him to believe in a Supreme Mind: his moral nature directs him to believe that the course of human affairs, and the condition of men, both as individuals and as bodies, is determined by the providential government of God.
