With one eye you are looking at the outside world, while with the other you are looking within yourself.
Quoted at History of Painters
Every great work of art should be considered like any work of nature. First of all from the point of view of its aesthetic reality and then not just from its development and the mastery of its creation but from the standpoint of what has moved and agitated its creator.Amedeo Modigliani
The function of art is to struggle against obligation.Amedeo Modigliani
