Surrealist: Many artists mistakenly think that models need be taken only from outside the psyche. Although human sensibility can confer beauty upon even the most vulgar external objects, using the power of artistic representation solely to preserve and reinforce objects that would exist even without artists is an ironic waste. Which one of the following most accurately expresses the conclusion of the surrealist's argument? ['Artistic representation is used solely to preserve and reinforce objects.', "An artist's work should not merely represent objects from outside the psyche.", 'Artists should not base all their work on mere representation.', 'Great art can confer beauty even upon very vulgar external objects.']
