"If any error have been committed, or any thing hath been spoken more freely, pardon my youth, for I wrote this being scarce a young man, that I may excuse myself, and say, whilst I was a child I spake as a child, and I understood as a child, but being become a man, I retracted those things which I did being a boy, and in my book of the vanity and uncertainty of Sciences I did, for the most part, retract this book But here, haply, you may blame me again, saying, "Behold, thou, being a youth, didst write, and now, being old, hast retracted it; what, therefore, hast thou set forth? " I confess, whilst I was very young, I set upon the writing- of these books, but, hoping that I should set them forth with corrections and enlargements— and for that cause I gave them to Trithemius, a Neapolitanian Abbot... a man very industrious after secret things. But it happened afterwards that, the work being intercepted, before I finished it, it was carried about imperfect and impolished, and did fly abroad in Italy, in France, in Germany, through many men's hands; and some men, whether more impatiently or imprudently I know not, would have put it thus imperfect to the press, with which mischief, I, being affected, determined to set it forth myself, thinking that there might be less danger if these books came out of my hands with some amendments than to come forth, torn and in fragments, out of other men's hands."
