Quote: Oscar Wilde

The moment you think you understand a great work of art, it's dead for you.

- Oscar Wilde

I beg to differ... I think that when you think you understand a work of art you appreciate it more. You feel like you have a bond with the artist, an inside joke.
Understanding it does take the fun away from pondering the meaning of art, but there so much art to ponder!! Better to have inside jokes...
