QuoteDo you mean Lucian's view as elsewhere stated? Because I was taking the thrust of his position as you stated to be applicable to Epicurus' school as well as other ones.
I was primarily thinking of this other letter, which is the most relevant and accessible of Lucian's works that I've read. His expressed admiration for Epicurus in this letter may be a courtesy to his Epicurean correspondent, but I personally think Lucian found Epicureanism less exasperating than some of the other schools.
Letter to Celsus, Alexander the Oracle-Monger:
Alexander, the Oracle-Monger, the False Prophet | Alexander [The Lucian of Samosata Project]
That one is a fun read, I definitely recommend it!
