From Gerhard Richter's note from 1966...
I pursue no objectives, no system, no tendency;
I have no programme, no style, no direction.
I have no time for specialised concerns,
working themes, or variations that lead to mastery.
I steer clear of definitions. I don’t know what I want.
I am inconsistent, non-committal, passive;
I like the indefinite, the boundless; I like continual uncertainty.

this goes against all art school sensibility doesnt it....the things we dont know
