There are only two kinds of people who are really fascinating – people who know absolutely everything, and people who know absolutely nothing.
– Oscar Wilde
The Picture of Dorian Gray, Chapter 7. This example of paradoxical and seemingly contradictory witticism by Lord Henry is what helped make Oscar Wilde into a 19th century celebrity, one of the funniest men that has ever lived, and one of the most quoted authors in the world. Henry imparts this wisdom to Dorian, who is upset because Sibyl has performed badly in her play, and basically tells him to look on the bright side of life.
