" 'Nonsense! A good artist is always prepared to learn', said the Dean. 'Interesting thing, these fellows never seem to get the idea of perspective--'
The Bursar thought, or recieved the thought: that's because perspective is a lie. If I know a pond is round then why should I draw it oval? I will draw it round because round is true. Why should my brush lie to you just because my eye lies to me?
It sounded like quite and angry thougt. "
