Max Bill's dual career as both architect and artist resulted in a body of sculptural work that balanced between the intellectual and the intuitive. He believed that sculpture should take clear, concrete forms, and develop symmetrically from a core. Bill stated: "Concrete Art is autonomous in its specificity. It is the expression of the human spirit, destined for the human spirit, and should possess that clarity and that perfection which one expects from works of the human spirit" (quoted in "Concrete Art," Max Bill, exh. cat., Albright-Knox Art Gallery, 1974).
