But we can at present only hint at this. In respect to the reasonings of these scientific discoverers (as they claim to be), we may say that their fallacies get currency from this very cause, namely, the general want of discrimination in respect to the true bounds of fundamental ideas, and that abuse of language which is the necessary result. If the consequences were not so serious, nothing could be more amusing than their pretensions, or their method. They would have us believe that they are the martyrs--Galileos--Bacons--Harveys, all of them. Each one is a suffering Servetus, while all the bigotry of the theological world, with all its inquisitorial priests and furious Calvins, is ever ready to crush their new science, and give the crown of martyrdom to its devoted teachers. They have, too, the sagacity to perceive that audiences, in general, love to be addressed in the technics of a scientific style, whether rightly used or not. The vender of quack medicines has discovered the same secret; and hence he, too, has his array of causes and effects, and fluids, and mediums, and counteracting forces, and grand systems of circulation, and positive and negative states. To be thus addressed raises the hearer or reader at once in his own estimation, and thus prepares him, sometimes, for the reception of almost any kind of nonsense. He acquires, too, an interest in these high matters; and if not himself an actual martyr to science, becomes at least a sympathizer with those who are doomed to all this infamous persecution. The usual course has now become so stereotyped, that one who has attended a number of lectures of this kind, will be able to predict the general method of remark quite as well as Davis is said to have foretold that of Dr. Bushnell. He will be certain of the very places where the peculiar and most original cant of the school will be sure to come in. He will know just when and where to look out for Galileo and the priests, and the Puritans and the Quakers, and Fulton and the steam-engine. He anticipates precisely the spot where the lecturer will tell us how Bacon "used up" the Stagyrite, and how wonderfully knowledge has grown since that remarkable event, and how all previous progress was preparatory to this new science, which it has been reserved for our bold martyr not only to discover in its elements, but to present full formed and full grown to his astonished hearers,--and which, moreover, he generously offers to teach to private classes (the ladies to be by themselves) at the exceedingly reasonable rate of ten dollars per course.
