Indifference to the fine arts comes close to barbarism.
As quoted in Nineteenth and Twentieth Century Architecture, Vol. 11 (1976) by Garland Publishing, p. 94; also in The Dictionary of Art, Vol. 28 (1996) by Jane Turner
Schinkel's aesthetic was not a crudely materialistic "truth to material" affair… but rather an attempt to inform iron and other industrial materials with an appropriate beauty through the direct collaboration of the artist in the manufacturing process.Karl Friedrich Schinkel
Schinkel was not arbitrary in his use of historical modes but rather eclectic in the best sense of the word. He could search the past for its conspicuous successes using them both freely and discursively as the basis for a contemporary architecture.Karl Friedrich Schinkel
