" After a lapse of 205 years since the first publication in 1647, of Lilly's Introduction to Astrology, there would be no necessity for an apology for its re-appearance, were it not for the prevailing fashion of the day, which is to rail at and vituperate that science, and all who dare to say a word, not in its favor, but in favor of examining into its merits, with a view to ascertain what were the grounds on which our honest ancestors believed, and strictly followed, that which we conceive only fit for ridicule. As I have long outlived the days when I, like many others, thought myself at liberty to laugh at, and condemn, what I did not understand; the world will forgive me if I be bold enough to advise those who value truth, to spend a few days (and but a few days will be necessary) in examining the principles laid down in this work, and applying them to their own individual cases, before they join the herd of learned and unlearned in pledging their words to a false assertion, viz. that Astrology is an unfounded science. If any man will take the trouble to examine for himself, and should find that the prejudices of his education against the science of foreseeing the future, and many other matters which it teaches, are in reality well-founded, and that it has no claims to truth, then will he have the proud satisfaction of knowing, that his opinions on a matter of some consequence are based on experiment, and are the result of his own conviction, not of another person's assertion. On the other hand, if he find truth flash with lightning force upon his mind, and convince him that Astrology, notwithstanding prejudice and abuse, is founded in nature, and is indeed a noble science, given by a benevolent Creator to enlighten man in his wanderings, and enable him to shun the vice and folly which his passions throw in his path; then will he, if a spark of piety exist within his breast, offer thanks to that Creator for the blessing he has discovered. In either case, he must admit that I do him a service in putting forth this plain and simply means of discovering the truth..."
