***"They mistake for happiness the mere absence of pain"** We have had several threads lately relevant to the argument as to whether reason or the emotions take precedence in Epicurean philosophy. If you're not familiar with it, and if you continue to be surprised at the Epicurean answer, be sure to check out Thomas Jefferson's famous HEAD AND HEART letter which I will submit to you follows Jefferson's Epicurean understandings. He's not criticizing Epicurus in the passage I quote - he's SUPPORTING Epicurus. The full letter is too long to post here in this thread but be sure to read far enough to see which gets the upper hand. Here is an excerpt from the conclusion but please read the whole letter:
Heart. "... Let the gloomy Monk, sequestered from the world, seek unsocial pleasures in the bottom of his cell! Let the sublimated philosopher grasp visionary happiness while pursuing phantoms dressed in the garb of truth! Their supreme wisdom is supreme folly: and they mistake for happiness the mere absence of pain. Had they ever felt the solid pleasure of one generous spasm of the heart, they would exchange for it all the frigid speculations of their lives, which you have been vaunting in such elevated terms."
