Each card is printed on both sides with a single word selected by Hendricks "in accordance with no fixed laws. Some are likes, others are antitheses. often the pairs are reversible, sometimes not." The author suggests playing with the cards like building blocks to make whatever individual creation is desired. "Language Box is an invitation to the reader to involve himself in this process of creative synthesis. It is an attempt to break out of, not to break down, traditional habits and inhibitions in order to arrive at a richer, fresher sense of language and the world." -- Source of annotation: Marvin or Ruth Sackner.
