It has been observed here this morning that we are called fanatics. Bless me! That is nothing. Who has not been called a fanatic who has discovered anything new in philosophy or science? We have all read of Galileo the astronomer, who, contrary to the system of astronomy that had been received for ages before his day, taught that the sun, and not the earth, was the center of our planetary system? For this the learned astronomer was called "fanatic," and subjected to persecution and imprisonment of the most rigorous character. So it has been with others who have discovered and explained new truths in science and philosophy which have been in opposition to long-established theories; and the opposition they have encountered has endured until the truth of their discoveries has been demonstrated by time. The term "fanatic" is not applied to professors of religion only. How was it with Dr. Morse, when shut up in the attic of an old building in Baltimore for more {401} than a year, with a little wire stretched round the room, experimenting upon it with his battery, he told a friend that by means of that he could sit there and talk to Congress in Washington? Was he not considered a fanatic, and wild, and crazy? Certainly he was; and so it was with Robert Fulton, when he was conducting his experiments with steam and endeavoring to apply it so as to propel a vessel through the water. And all great discoverers in art, science, or mechanism have been denounced as fanatics and crazy; and it has been declared by their contemporaries that they did not know what they were saying, and they were thought to be almost as wild and incoherent as the generality of the people now think George Francis Train to be. 13:270. How difficult it is to teach the natural man, who comprehends nothing more than that which he sees with the natural eye! How hard it is for him to believe! How difficult would be the task to make the philosopher, who, for many years, has argued himself into the belief that his spirit is no more after his body sleeps in the grave, believe that his intelligence came from eternity, and is as eternal, in its nature, as the elements, or as the Gods. Such doctrine by him would be considered vanity and foolishness, it would be entirely beyond his comprehension. It is difficult, indeed, to remove an opinion or belief into which he has argued himself from the mind of the natural man. Talk to him about angels, heavens, God, immortality, and eternal lives, and it is like sounding brass, or a tinkling cymbal to his ears; it has no music to him; there is nothing in it that charms his senses, soothes his feelings, attracts his attention, or engages his affections, in the least; to him it is all vanity. 1:2. {402} True principles will abide, while all false principles will fall with those who choose and cleave to them. 7:65.
