Plutarch, De defectu oraculorum
Goodwin, Ed.

Thus then spake Cleombrotus: I could, says he, relate several such stories as these; but it is sufficient that what has been said as yet does not contradict the opinion of any one here. And we all know, the Stoics believe the same as we do concerning the Daemons, and that amongst [p. 25] the great company of Gods which are commonly believed, there is but one who is eternal and immortal; all the rest, having been born in time, shall end by death. As to the flouts and scoffing of the Epicureans, they are not to be regarded, seeing they have the boldness to treat divine providence with as little reverence, calling it by no better a name than a mere whimsy and old wives' fable. Whereas we, on the contrary, assert that their Infinity is fabulous and ridiculous, seeing among such endless numbers of worlds there is not one governed by reason or divine providence, they having been all made and upheld by chance. If we cannot forbear drolling even in matters of philosophy, they are most to be ridiculed who bring into their disputes of natural questions certain blind, dumb, and lifeless images, which appear they know not where nor when, which, they say, proceed from bodies, some of which are still living, and others long since dead and rotten. Now, such people's opinions as these must needs be exploded and derided by all rational men; yet these very people shall be offended and angry at a man's saying there be Daemons, and that they subsist both by reason and by Nature, and continue a long time.
