There are two worlds of knowledge—outward and inward. Knowledge of the outward world comes to us through the senses, by observation; knowledge of the inward world comes to us through the consciousness, by insight or inspiration. Every man’s knowledge has come to him by both of these methods. The soul has a perceptive power with which it can look either way. It looks outward through the senses, and perceives an external world; it looks inward through the consciousness, and perceives an internal world. It looks outward, and perceives forms, hears sounds, becomes acquainted with external nature. It looks inward, and becomes acquainted with justice, holiness, love, freedom, duty, sin, immortality, the infinite, the eternal, God. But just as it depends on various conditions as to what a man shall see through the senses in time and space, so it depends on other conditions as to what a man shall see beyond time and space in the spiritual world. The conditions in the first instance are, good perceptive organs, a genius for observation, educated powers for observation, knowledge of what to observe, and finally opportunities for observation, or being able to go where the things are which are to be seen. A blind man standing in front of the Parthenon would be no authority to us as to its architecture; neither would the most sharp-sighted person who should happen in be in America, instead of Greece. So an Indian, with the finest perceptive faculty, and standing directly in front of this majestic temple, would give a very poor account of it, from want of previous knowledge. He, only, would be an authority to us in regard to such a building, who should combine with good perceptive organs, and some knowledge of the subject, an opportunity for looking at it. When we speak of inspiration, we mean, in regard to the inward world, exactly the same thing. We mean that a man has his spiritual organs in a healthy condition, that he has some knowledge of spiritual things, and that he has been placed by divine Providence where he is able to see them. Some men are lifted into a world of spiritual perception, when they see things not seen by other men. They become prophets, apostles, lawgivers to the human race. They are invested with authority. Men believe what they say, and do what they command, and put their souls into their hands, just as they trust their bodies to the guide of the pilot. These are the inspired men—the men to whom revelations have been made. They have authority, because they have been where we have not been, and seen what we have not seen. But they have not infallibility, because, as the apostle says, they have this treasure in earthen vessels. This divine knowledge is contained in a finite, and therefore fallible mind. But we see by means of our former illustrations that to grant their fallibility does not detract at all from their authority.
