Raise High the Roof Beam, Carpenters and Seymour: an Introduction is about the inherent difficulty of expressing truth in plain language. Confusion and miscommunication dominate "Roof Beam," and the frustration of communicating through written work is at the heart of "Seymour." Arguably, the only effective communication in the first half of the book is non-verbal. As evidenced by the Zen koan, certain truths can only be understood emotionally or spiritually, not in a way that could be expressed verbally. On top of it all, the alienating force of the peculiar Glass family language acts as an additional barrier for narrator Buddy Glass in communicating to other characters and to the reader.
Words are not an effective means of communication in "Raise High the Room Beam, Carpenters" and "Seymour: an Introduction."
Raise High the Roof Beam, Carpenters and Seymour: an Introduction argues that communication must take place on a spiritual level.
