NATURAL HISTORY OF ENTHUSIASM. by ISAAC TAYLOR ... δύο ἐστὶ, τὸ μὲν ἀρετὴ φυσικὴ, τὸ δ' ἡ κυρία. From the Ninth London Edition. New York: Robert Carter & Brothers No. 530 Broadway 1859. ADVERTISEMENT. The belief that a bright era of renovation, union, and extension, presently awaits the Christian Church, seems to be very generally entertained. The writer of this volume participates in the cheering hope; and it has impelled him to undertake the difficult task of describing, under its various forms, that FICTITIOUS PIETY which hitherto has never failed to appear in times of unusual religious excitement, and which may be anticipated as the probable attendant of a new development of the powers of Christianity. But while it has been the writer's principal aim to present to the Christian reader, in as distinct a manner as possible, the characters of that specious illusion which too often supplants genuine piety, he has also endeavored so to fix the sense of the term Enthusiasm as to wrest it from those who misuse it to their own infinite damage. The author would say a word in explanation of his choice of a term in this instance; and of the extent of meaning he has assigned to it. The best that can be done, when matters of mind are under discussion, is to select, from the stores of familiar language, a word which, in its usual sense, approximates more nearly than any other to the abstraction spoken of. To require from an ethical writer more than this, would be to demand that, before he enters upon his subject, he should both renovate the science of mind, and reform his mother tongue: for when things not yet scientifically defined are to be spoken of, it must needs happen that, in proportion to the accuracy with which they are described, there will be apparent occasion for taking exception against the sense imputed to the term employed.
