Blockheads

"No one shows himself as he is, but wears his mask and plays his part. Indeed, the whole of our social arrangements may be likened to a perpetual comedy; and this is why a man who is worth anything finds society so insipid, while a blockhead is quite at home in it. "

Arthur Schopenhauer (1788-1860) "Studies in Pessimism: Further Psychological Observations"
