To my mind the Old Masters are not art; their value is in their scarcity.
The people who make art their business are mostly imposters.

Half the work that is done in this world is to make things appear what they are not.
You are only what you are when no one is looking.
The world is governed more by appearances than by realities, so that it is fully as necessary to seem to know something as to know it.
Apathy is a sort of living oblivion.
Borrow trouble for yourself, if that is your nature, but don't lend it to your neighbors.
