Not the jester always: The common sense of a person is found in his seriousness, for wisdom ranks higher than wit. One who is always the buffoon is really never the man. He classes himself with the liar, in that neither is believed: not the latter, because his word is doubted, and not the former, because of his scoffing. For it is never known if what was said was weighed in the mind, which in no instance can hive been much. There is nothing more banal than continuous banter. Thus some get the reputation of being witty, but they endanger thereby their reputation of being wise. The humorous may be allowed its moment, but for all the rest, the serious.
~ Baltasar Gracian, The Art of Worldly Wisdom (1647)
