Charles Brockden Brown is widely considered one of early America's foremost writers, despite dying before the age of 40. His works were hailed as the predecessor of works such as James Fenimore Cooper's.
Here's an excerpt from the beginning:
"The following Work is delivered to the world as the first of a series of performances, which the favorable reception of this will induce the Writer to publish. His purpose is neither selfish nor temporary, but aims at the illustration of some important branches of the moral constitution of man. Whether this tale will be classed with the ordinary or frivolous sources of amusement, or be ranked with the few productions whose usefulness secures to them a lasting reputation, the reader must be permitted to decide.
The incidents related are extraordinary and rare. Some of them, perhaps, approach as nearly to the nature of miracles as can be done by that which is not truly miraculous. It is hoped that intelligent readers will not disapprove of the manner in which appearances are solved, but that the solution will be found to correspond with the known principles of human nature. The power which the principal person is said to possess can scarcely be denied to be real. It must be acknowledged to be extremely rare; but no fact, equally uncommon, is supported by the same strength of historical evidence.
Some readers may think the conduct of the younger Wieland impossible. In support of its possibility the Writer must appeal to Physicians and to men conversant with the latent springs and occasional perversions of the human mind. It will not be objected that the instances of similar delusion are rare, because it is the business of moral painters to exhibit their subject in its most instructive and memorable forms. If history furnishes one parallel fact, it is a sufficient vindication of the Writer; but most readers will probably recollect an authentic case, remarkably similar to that of Wieland.
It will be necessary to add, that this narrative is addressed, in an epistolary form, by the Lady whose story it contains, to a small number of friends, whose curiosity, with regard to it, had been greatly awakened. It may likewise be mentioned, that these events took place between the conclusion of the French and the beginning of the revolutionary war. The memoirs of Carwin, alluded to at the conclusion of the work, will be published or suppressed according to the reception which is given to the present attempt."
