I have in this declaration insensibly overstepped the limits which I had determined not to pass: let me be forgiven; for it is hope which hath carried me forward. In such a mixed assemblage as our age presents, with its genuine merit and its large overbalance of alloy, I may boldly ask into what errors, either with respect to person or thing, could a young man fall, who had sincerely entered upon the course of moral discipline which has been recommended, and to which the condition of youth, it has been proved, is favourable?

Studied in the history of society, and versed in the secret laws of thought, he can pass regularly through all the gradations, can pierce infallibly all the windings, which false taste through ages has pursued, from the very time
