=2. Importance of Belief in God.=--"The existence of a Supreme Being is, without doubt, the sublimest conception that can enter the human mind, and, even as a scientific question, can have no equal, for it assumes to furnish the cause of causes, the great ultimate fact in philosophy, the last and sublimest generalization of scientific truth. Yet this is the lowest demand it presents for our study; for it lies at the very foundation of morality, virtue, and religion; it supports the social fabric, and gives cohesion to all its parts; it involves the momentous question of man's immortality and responsibility to supreme authority, and is inseparably connected with his brightest hopes and highest enjoyments. It is, indeed, not only a fundamental truth, but the grand central truth of all other truths. All other truths in science, ethics, and religion radiate from this. It is the source from which they all flow, the center to which they all converge, and the one sublime proposition to which they all bear witness. It has, therefore, no parallel in its solemn grandeur and momentous issues."--_The same._ =3. Belief in God, Natural and Necessary.=--Dr. Joseph Le Conte, Professor of Geology and Natural History in the University of California, and a scientist of world-wide renown, has spoken as follows:--"_Theism_, or a belief in God or in gods, or in a supernatural agency of some kind, controlling the phenomena around us, is the fundamental basis and condition of all religion, and is therefore universal, necessary, and intuitive. I will not, therefore, attempt to bring forward any proof of that which lies back of all proof, and is already more certain than anything can be made by any process of reasoning. The ground of this belief lies in the very nature of man; it is the very foundation and groundwork of reason. It is this and this only which gives significance to Nature; without it, neither religion nor science, nor indeed human life, would be possible. For, observe what is the characteristic of man in his relation to external Nature. To the brute, the phenomena of Nature are nothing but sensuous phenomena; but man, just in proportion as he uses his human faculties, instinctively ascends from the phenomena to their cause. This is inevitable by a law of our nature, but the process of ascent is different for the cultured and uncultured races. The uncultured man, when a phenomenon occurs, the cause of which is not immediately perceived, passes by one step from the sensuous phenomenon to the first cause; while the cultured, and especially the scientific man, passes from the sensuous phenomena through a chain of secondary causes to the first cause. The region of second causes, and this only, is the domain of science.
