Theorem II. Any feel which feeling has not informed me of, is unknown — Alexander Bryan Johnson

"All that the book contains is the elucidation of but one precept: namely, to interpret language by nature. We [generally and incorrectly] reverse the rule and interpret nature by language."

"Man exists in a world of his own creation. He cannot step, but on ground transformed by culture; nor look, but on objects produced by art. The animals which constitute his food are unknown to nature, while trees, fruits, and herbs, are the trophies of his labour. In himself nearly every natural impulse is suppressed as vicious, and every mortification solicited as a virtue. His language, actions, sentiments, and desires are nearly all factitious. Stupendous in achievement, he is boundless in attempt. Having subdued the earths surface, he would explore its centre; having vanquished diseases, he would subdue death. Unsatisfied with recording the past, he would anticipate the future. Uncontented with subjugating the ocean, he would traverse the air. Success but sharpens his avidity, and facility but augments his impatience."

"As theories are the means by which we attempt to discourse of external existences that our senses cannot discover; and as the desire for such discourse originates a large portion of our theories; I will teach you the capacity of language for such an employment, and thereby enable you to judge more understandingly than you can at present, the utility of most theories, and the signification of all."

"Man soon finds what he wants to find. If he cannot find it otherwise, he creates it for his special enjoyment: for instance, if a man wants to see a ghost, he need only promulge his wish some night around a decaying fire, with a few alarmed and shocked listeners. Then let him ascend in the dark to a remote chamber, carefully looking over his shoulder every few moments; and if he will not see a ghost, he will feel as if he saw one, and that will be tantamount thereto."

"War and fights, like courtship and kisses, are seldom interesting except to the actors and their connexions; hence I will not burden my readers with the military operations of these remote regions."

"In every particular in which a picture constitutes a sight that is not identical with the sight represented, the picture will fail to communicate the represented object."
