‘Dear Albert’ had one of the great spirits to go along with that incredible mind of his! This quote seems to be a corollary to another quote of his: “Not everything that can be counted counts, and not everything that counts can be counted”. That is, those that give very little real thought to their opinions are the very ones who are the most vocal, i.e. countable. They seem to operate on the principle that if I force you to hear this then it is so!! As my father-in-law used to say, they keep talking long after they’ve run out of something to say!
