“Even a fool,” it is said, “when he asks questions,” is counted wise. Prov. xvii. 28, lxx.  But when a wise man asks questions, he makes even a fool wise.  And this, thank God, is my case, as often as I receive a letter from your industrious self.  For we become more learned and wiser than we were before, merely by asking questions, because we are taught many things which we did not know; and our anxiety to answer them acts as a teacher to us.  Assuredly at the present time, though I have never before paid attention to the points you raise, I have been forced to make accurate enquiry, and to turn over in my mind both whatever I have heard from the elders, and all that I have been taught in conformity with their lessons.
