But may not an adequate knowledge of God be obtained _by the exercise of the faculties of the human mind upon external nature_, _or in some other way_? The Apostle St. Paul says something which rather favours this view, when he declares that “the invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made, even His eternal power and Godhead; so that they are without excuse” (Rom. i. 20): and we believe that a considerable insight into the nature of God, and the probable character of His dealings with us may be obtained in the manner to which we have referred. Still we have only to look at the ever varying and degrading notions which have, at all times, prevailed in many parts of the world respecting the Divine Being, to perceive that a more clear method of obtaining knowledge about Him would, to say the least of it, be a most valuable boon. The method under consideration has not practically issued as we might have hoped that it would; and therefore there is reason to expect, that God might make use of some more direct way of communicating to us a knowledge of Himself.
Another possible mode of communicating a knowledge of God would be, _by implanting in the mind of man_, _an idea corresponding_, _so far as might be needful_, _to the nature of God_. But a belief in the existence of anything of this kind is open to several objections. If such an idea existed, it must, to answer the required end, be sufficiently clear and well defined to give at least a tolerably accurate notion of the Deity, and must also bring with it a well-grounded conviction of its correspondence to the reality. But the variety of opinions which have been entertained on the subject forbid us to believe that any such idea as this exists. Search as far as we can into our own minds, we are unable to discover anything approaching to such a notion of the Divinity. It appears too, that, notwithstanding some speculations as to time and space, which, in the opinion of some, bear a slightly exceptional character, there is no good reason to believe that we acquire other kinds of knowledge in the manner under consideration; and, if this be so, there is a strong presumption against a knowledge of the Deity being obtained in this way.
