Yep, like the gold nuggets of human wisdom in Shakespeare.Many of the so called classics are overrated, but they do have ideas that can educate a person.
'Candide', by Voltaire, missed the list.
I like reading, but Philosophy classes in school stunk. Kissing the instructor's hind-quarter and agreeing with their interpretation of what a dead author meant. Same with Literature and Humanities and Ethnic Studies classes.
One that is underrated in human insight in my opinion these days is the Bible. Not in a preachy religious way.
