1 Corinthians 8:2
And if any man think that he knows any thing, he knows nothing yet as he ought to know.
The wisest men feel that they know nothing compared with what they are capable of knowing. I was struck with a remark that a man once made to me on this subject. To my mind he was a marvel of learning. He seemed thoroughly educated in every direction. As now there is not a tree in the forest which, if you tap it, will not run sap, so there was not a side on which you could touch him where his knowledge did not seem complete. I said to him one day, "If I knew a tithe of what you know, I should think myself very fortunate." Said he, "Henry, I seem to myself like a basket in which are being carried away the fragments of a hotel — a bit of this, the fag-end of that, and all sorts of things jumbled up together. I do not know anything except little fragmentary parts of this, that, and the other."
(H. W. Beecher.)
