Δαφνη Ευτυχια Αρθουρος

[I'm in the mood to go all over-analytical. Bear with me; it's more using your comment as a jumping off place for a language-riff than really arguing with you.]

Well, in the author's (or at least the character's) defense, I'll point out the conditional. Just as the original is oft' misquoted (it's not "Ignorance is bliss" -- it's "Where ignorance is bliss, 'tis folly to be wise" (which I'd misremembered as "If ignorance is bliss, then 'tis folly to be wise" -- closer to the original than I usually hear but still not exact -- until I looked it up just now), Florence's exasperated utterance begins with the important 'if'. And also, since Sam Starfall, the source of her exasperation, is, like her, a cartoon character, the danger-to-himself of his own ignorance is mitigated considerably compared to how it works for us three-dimensional folks. (With apologies to Messrs. Davies et al (http://www.lyricsfreak.com/k/kinks/celluloid+heroes_20079243.html): Cartoon heroes never feel any pain / And cartoon heroes never really die. Though they do get their hearts broken.)

This would, of course, be a lot less likely to spark so much disagreement if it had been phrased either, "If ignorance were bliss ..." or "If ignorance was bliss ..." (with a "would be" in the second half). Then again, most people still misremember, or at least mis-speak, the famous "For the love of money is the root of every evil ...", and that one (at least in the translations I'm used to seeing) is completely straightforward tense-wise.

So I think the main objection here isn't so much that the statement is incorrect, as that the condition it describes only occurs as a special case and thus may not be considered germane to most everyday circumstances.
