These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Finnegan's Wake
Dancing Bear: Ask a person what he or she knows about Finnegans Wake: the first thing to come to mind is most likely the style of the book, rather than the actual content. Though to be fair, the former makes the latter rather hard to discern.
True Art Is Incomprehensible: Quite possibly the purest form of true art, made by the distillation of multiple layers of mutual meta-incomprehensibility. Joyce said it would take about three centuries for anyone to figure out what was really going on in the book. One suspects he'd be disappointed if Wikipedia really has the explanation of what he was saying.
Vindicated by History: Most of Joyce's contemporaries and even his own family thought the book was stupid or a joke. It initially had negative reviewers, although one reviewer held off on judging the work, predicting that in the future, "with sufficient study and with the aid of the commentary that will doubtless arise, one might be ready for an attempt to appraise it." He was right.
