 A cathedral is not as such more beautiful than an airplane, … a hymn than a mathematical equation. … A well-made sword is not less beautiful than a well-made scalpel, though one is used to slay, the other to heal. Works of art are only good or bad, beautiful or ugly in themselves, to the extent that they are or are not well and truly made, that is, do or do not express, or do or do not serve their purpose. (Coomaraswamy 1977, 75)
