beldaraan, I tore my husband away from his paper this morning to read the quote, because he speaks a little French. He said this as a line from a poem by Charles Baudelaire and went on to say that Baudelaire was famed for trundling off to Africa with his lover to consume vast amounts of drugs and write poems about it. (I am paraphrasing
). Sure enough, it's from a poem called "Au Lecteur" (To the Reader), which is one of a number of poems from a group collectively called "Les Fleurs du mal" ("The Flowers of Evil").
I looked up a translation for your line on the net, and found this:
—You know him, reader,—hypocrite,—my twin!
It looks like the poem is a dig at the French public who tut-tutted Baudelaire's poems? Maybe what he's saying in that line is:
--Hey, you're all busy condemning what I write, but you actually read it, so in the end you're all hypocrites--
