I was tempted to include that on my list of unreadables. Ironically, the first paragraphs of that book provide a parable most appropriate for this thread, I paraphrase:
A rube goes in to town one day to shop. And in a stall he sees beautifully colored fruits that are new to him, and so he purchases a pound of them. On his way home he stops for lunch and begins to eat his newly bought fruit. The more he eats the hotter his mouth becomes until he is literally crying from the pain.
However, being an ignorant rube, and seeing that this is the only food he purchased while in town, he continues to eat until, of course, he dies.
Said Beezelbub to his grandson, "if you don't like the fruit; stop eating."
I took the sage's advice and set the book aside.
Any book is good mental exercise, and that one was a marathon.
