"So it is a philosophical dispute. Daniel, I am an old man. I’ve not been in London since 1677. What are the chances I shall ever return? And Newton—who has never set foot outside of England—will not come to me . I shall not have another opportunity to meet with him. I will remain in London incognito —no one need never know I was here—and find some way to engage Newton in Philosophick discourse and help him out of the labyrinth in which he has wandered for so many years. It is a labyrinth without a roof, affording a clear view of the stars and the moon, which he understands better than any man; but behold, when Newton lowers his gaze to what is near to hand, he finds himself trapped and a-mazed in dark serpentine ways."
