"We must laugh and philosophize at the same time, and do our household duties, and employ our other faculties, and never cease proclaiming the sayings of the true philosophy." Epicurus VS41 (Bailey)
The proclaim part comes from the Ancient Greek: ...καὶ μηδαμῇ λήγειν τὰς ἐκ τῆς ὀρθῆς φιλοσοφίας φωνὰς ἀφιέντας: literally, "and in no way cease letting loose the cries of the correct philosophy" or paraphrased "and don't stop whooping it up about Epicurean Philosophy!" Ones of the definitions of φωνὰς is "usually of the human voice: voice, cry, yell"
This excerpt is especially important: With this Saying Epicurus disavows any allegiance to ascetic, monastic ideals. A philosophically enlightened person is not at all like the stereotype of the dour hermit, less yet the reclusive misanthrope. Such a person feels free to laugh out loud, and practices philosophy daily, naturally. Such a person lives a normal life, minding his/her business, managing his/her household, handling all the daily, familiar affairs of domestic life.
