now prevailing in the world, is due to the fact that men are told that they are commanded to believe, as if they were to be passive recipients of what is asserted, and because so little is addressed to their understandings. I do not wish to be understood as maintaining that there is no place for authority in matters of what is called religious belief. I am quite sensible that there may be such a thing as authority even in regard to our beliefs; that it is quite within the range of possibilities that there should be such a relation between the human soul and an infinite Creator as to require the creature to accept by faith whatever a proved revelation requires that intelligent creature to believe. But, in view of the fact that what is specially called revealed religion is addressed to an intelligent creature, to whom the revelation itself must be proved by some evidence that will satisfy the mind, there is an evident necessity for treating the rationality of a belief in God as an independent question. In some way, by some process, we must reach a belief in the existence of a being before we can consider the claims of a message which that being is supposed to have sent to us. What we have to work with, before we can approach the teaching of what is called revealed religion, is the mind of man and the material universe. Do these furnish us with the rational basis for a belief in God? And here I shall be expected to say what I mean by a belief in God. I have neither so little reverence for what I myself believe in, nor so little respect for my readers, as to offer them anything but the common conception of God. All that is necessary for me to do, in order to put my own mind in contact with that of the reader, is to express my conception of God just as it would be expressed by any one who is accustomed to think of the being called God by the Christian, the Jew, the Mohammedan, or by some other branches of the human race. These different divisions of mankind may differ in regard to some of the attributes of the Deity, or his dealings with men, or the history or course of his government of the world. But what is common to them all is a belief in God as the Supreme Being, who is self-existing and eternal, by whose will all things and all other beings were created, who is infinite in power and wisdom and in goodness and benevolence. As an intellectual conception, this idea of a Supreme Being, one only God, who never had a beginning and can have no end, and who is the creator of all other beings, excludes, of course, the polytheism of the ancient civilized nations, or that of the present barbarous tribes; and it especially excludes the idea of what the Greeks called Destiny, which was a power that governed the gods as well as the human race, and was anterior and superior to Jove himself. The simple conception of the one God held by the Christian, the Jew, or the Mohammedan, as the First Cause of the universe and all that it embraces, creating all things
