Bray - To pound wheat in a mortar with a pestle, in order to free the wheat from its husks and impurities, is to go through a far more elaborate process than threshing. But the folly of the fool is not thus to be got rid of. It sticks to him to the last; all discipline, teaching, experience seem to be wasted on him.
