Fifty or a hundred years ago, if any one had told the people of the East Indies that water could be congealed, and form ice so thick and hard that you could walk on and drive teams over it, they would probably have said, "We do not believe a word of it." Why? Because they did not know anything about it. A proper reply for all mankind to make under similar circumstances would be, "We do not know anything about what you say, and do not know whether we should have faith in it or not. Perhaps we should, but we have no evidence at present on which to found such a belief." You go down south here among some of our native Indian tribes, where some of the very best of blankets are made, and you will find them twisting their yarn with their fingers and little sticks, and their loom attached to the limbs of trees for weaving purposes. Show them a loom such as white people use, and it would be a perfect mystery to them. Sixty or seventy years ago a loom worked by water power would have been a mystery to an American, but there is no mystery in that today, because the process is understood. So it is with the East Indians and ice, for the chemist now, by a chemical process, will congeal the water and make ice of it before their eyes, and it is in this way, by testimony, evidence, and demonstration that ignorance and prejudice are removed, faith implanted and knowledge acquired. It is so with regard to all the facts in existence that we do not understand. 14:115.

There is no ingenious mind that has ever invented anything beneficial to the human family but what he obtained it from the one Source, whether he knows or believes it or not. There is only one Source whence men obtain wisdom, and that is God, the Fountain of all wisdom; and though men may claim to make their discoveries by their own wisdom, by meditation and reflection, they are indebted to our Father in Heaven for all. 13:148.

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 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.

True principles will abide, while all false principles will fall with those who choose and cleave to them. 7:65.

We should seek substantial information, and trust little to that kind of so-called learning that is based upon theory. We should pluck fruit from the tree of knowledge, and taste, then shall our eyes be open to see, our ears to hear and our hearts to understand. I would recommend the same course to those who have not embraced and tasted the sweets of "Mormonism." We should get wisdom by reading and by study. We should introduce the best books into our schools for the education and improvement of our children. Let our school teachers seek constantly to fasten upon the young mind useful information, and banish from their schools, every study that only tends to perplex the student and waste his valuable time. 9:369.

The Body and the Mind—Some think too much, and should labor more, others labor too much and should think more, and thus maintain an equilibrium between the mental and physical members of the individual; then you will enjoy health and vigor, will be active, and ready to discern truly, and judge quickly. Men who do much thinking, philosophers for instance, should apply their bodies to more manual labor in order to make their bodies more healthy and their minds more vigorous and active. 3:248.

Studies in Sunday Schools—We wish in our Sunday and day schools, that they who are inclined to any particular branch of study may have the privilege to study it. 13:61.

Wisdom—The person that applies his heart to wisdom, and seeks diligently for understanding, will grow to be mighty in Israel. 3:363.

Let wisdom be sown in your hearts, and let it bring forth a bountiful harvest. It is more profitable to you than all the gold and silver and other riches of earth. Let wisdom spring up in your hearts, and cultivate it. 8:140.
