The power which resides in him is new in nature, and none but he knows what that is which he can do, nor does he know until he has tried.

Yet things are knowable! They are knowable, because, being from one, things correspond. There is a scale: and the correspondence of heaven to earth, of matter to mind, of the part to the whole, is our guide.
