" Knowledge does not abolish faith but gives it a more inward meaning. He who "knows" theoretically does indeed enjoy metaphysical certainty, but such certainty does not yet penetrate his whole being; it is as if, instead of believing a description, one saw the object described but without the sight of it implying either a detailed knowledge or a possession of the object, for a single visual perspective does not of course teach us the whole nature of the thing seen; thus there is certainty regarding the object as such in this case, but uncertainty regarding its integral nature. To "know" an object perfectly means to "possess" it, "become" it, "be" it; if the sight of an object is very much more than an abstract belief in its existence, the realization of the object will likewise be infinitely more than the sight of it; metaphysical certainty thus stands in a sense between belief--"faith" in the ordinary sense of the word--and the realization of union. As long as a man is not delivered from the chains of existence, there is always an element of "faith" in his "knowledge"; otherwise there would be nothing separating him from the Reality "known" or "to be known".
