Very limited sales for this definition of the aesthetic, which is expanded into a discussion of medium and form in art. Man's motive impulse toward ""the imaginative unification of reality"" provides him with aesthetic experience; great art emerges only when the artist's relationship to form and medium are unified; a master artist, driven by a strong aesthetic impulse, can provide propaganda art of value. There is a nice imagery and an effective prose style which somewhat offset the difficulty of the subject and the seriousness of the treatment. Demands strict concentration.
