Usually, even a non-Christian knows something about the earth, the heavens and the other elements of the world, the motion and orbit[s]… and this knowledge he holds to as being certain from reason and experience. Now, it is a disgraceful and dangerous thing for an infidel to hear a Christian, presumably giving the meaning of Holy Scripture, talking nonsense on these topics; and we should take all means to prevent such and embarrassing situation, in which people show up vast ignorance in a Christian and laugh it to scorn.
