“The business of art is to enlarge and correct the heart and to lift our ideals out of the ugly and the mean through love of the ideal…The business of art is to appeal to the soul.”

Art Psalms (2008), Seven Statements on Mystic Art

La politique, quand elle est un art et un service, non point une exploitation, c'est une action pour un idéal à travers des réalités.

Homère est un des génies qui résolvent ce beau problème de l’art, le plus beau de tous peut-être, la peinture vraie de l’humanité obtenue par le grandissement de l’homme, c’est-à-dire la génération du réel dans l’idéal.

Context: Business art is the step that comes after Art. I started as a commercial artist, and I want to finish as a business artist. After I did the thing called 'art' or whatever it's called, I went into business art. I wanted to be an Art Businessman or a Business Artist. Being good in business is the most fascinating kind of art. During the hippies era people put down the idea of business – they'd say 'Money is bad', and 'Working is bad', but making money is art and working is art and good business is the best art.

Context: Art must must carry man's craving for the ideal, must be an expression of his reaching out towards it; that art must give man hope and faith. And the more hopeless the world in the artist's version, the more clearly perhaps must we see the ideal that stands in opposition — otherwise life becomes impossible! Art symbolises the meaning of our existence.
