view the wonderful Fabrick of the World, and the Beauty of the Stars, yet what would otherwiſe be Rapture and Extaſie, would be but a melancholy Amazement if he had not a Friend to communicate it to. I could wiſh indeed that all the World might not be my Judges, but that I might chuſe my Readers, Men like you, not ignorant in Aſtronomy and true Philoſophy; for with ſuch I might promiſe my ſelf a favourable hearing, and not need to make an Apology for daring to vent any thing new to the World. But becauſe I am aware what weak Hands it’s likely to fall into, and what a ſevere Sentence I may expect from thoſe whoſe Ignorance or Zeal is too great; it may be worth the while to guard my ſelf beforehand againſt the Aſſaults of thoſe ſort of People. [The Objections of ignorant Cavillers prevented.] There’s one ſort who knowing nothing of Geometry or Mathematicks, will laugh at it as a whimſical and ridiculous Undertaking. It’s an incredible Thing to them to talk of meaſuring the Diſtance and Magnitude of the Stars: And for the Motion of the Earth, they count it, if not a falſe, at leaſt a precarious Opinion; and no wonder then if they take what’s built upon ſuch a ſlippery Foundation for the Dreams of a fanciful Head and a diſtemper’d Brain. What ſhould we anſwer to theſe Men, but that their Ignorance is the Cauſe of their Diſlike, and that if they had ſtudied theſe things more, and viewed the Works of Nature nicely, they would have fewer Scruples? But few People having had an opportunity of proſecuting theſe Studies, either for want of Parts, Learning or Leiſure, we cannot blame their Ignorance; and if they reſolve to find fault with us for ſpending time in ſuch Matters, becauſe they do not underſtand the Uſe of them, we muſt appeal to properer Judges. [Theſe Conjectures do not contradict the holy Scriptures.]
