But perhaps Dostoevsky?

“You who so plod amid serious things that you feel it shame to give yourself up even for a few short moments to mirth and joyousness in the land of Fancy; you who think that life hath not to do with innocent laughter that can harm no one; these pages are not for you.” 

**The Merry Adventures of Robin Hood

Some worse than Others

“A professor is someone who talks in someone else’s sleep.”

**W. H. Auden
