In aesthetics, Rand defined art as a "selective re-creation of reality according to an artist's metaphysical value-judgments". According to her, art allows philosophical concepts to be presented in a concrete form that can be easily grasped, thereby fulfilling a need of human consciousness. As a writer, the art form Rand focused on most closely was literature, where she considered romanticism to be the approach that most accurately reflected the existence of human free will. She described her own approach to literature as "romantic realism".
