“There is grass on the earth, we see it—from the moon we would not see it—and on the grass are leaves, and in these leaves are small animals; but after that no more.—O presumptuous man!—The compounds are composed of elements, and the elements not.—O presumptuous man! Here is a fine reflection.—We must not say that there is anything which we do not see.—We must then talk like others, but not think like them.
267 The last proceeding of reason is to recognise that there is an infinity of things which are beyond it. It is but feeble if it does not see so far as to know this. But if natural things are beyond it, what will be said of supernatural?
268 Submission.—We must know where to doubt, where to feel certain, where to submit.” source
