Knowledge is food for the mind and nourishes and strengthens it as aliment does the body. Our youth learn to read the books which they are favoured with in consequence of the discovery of the art of printing, and they obtain great advantages by means of those books, while they remain entirely ignorant, many of them, of the art by which such a favour is put into their hands. But still it is healthy to the youthful mind, to receive the knowledge of this and other arts, and even to know that an art so extensively useful was not known in the world four hundred years ago. A person on being informed of the first discovery of this art, and of its being practiced, in the first place, with separate wooden types, might be disposed to doubt the ignorance of men in those times. He might think it incredible that any thing so easy, that even children can perform was unknown to the learned world in those times when learning flourished in ancient Greece and Rome. And I am of opinion that many now, who are disposed to doubt the circumstances which attended the first promulgation of the gospel, and even call themselves unbelievers, do in reality, owe even their existence and of course every blessing they enjoy to those facts of which they now doubt. Yes, sir, the light of reason, and the knowledge of moral principles, on which you feel disposed to place so much consequence, I am inclined to believe are reflections of that light which was the delightful theme of the evangelical Isaiah, chapters 6, 7, 8. "I the Lord hath called thee in righteousness, and will hold thine hand, and will keep thee, and give thee for a covenant of the people, for a light of the Gentiles; to open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house. I am the Lord; that is my name: and my glory will I not give to another, nor my praise to graven images." Am I deceived, sir, or is it evident, that the glorious LIGHT which illuminates our moral hemisphere, and distinguishes our country from barbarism and savage ignorance, is the gospel? The name of Jesus, his doctrine, the reformation, seceding from the Church of England and persecution for conscience sake, rank as causes of the settlement of New England by our forefathers, and of the existence of the men who are carrying on this correspondence. This is mentioned with a view to direct your mind to the consideration of that course of causes and effects by which we are enabled to reason on what wo call moral and physical principles. And a hope is entertained that due regard will be paid to this self-evident fact, that nothing ever took place without an adequate cause to produce it.
