Three authors comment upon each other's views as expressed in previous articles on the paragraph. Francis Christensen discusses the "sentence-based" theory and compares it to other descriptions of the paragraph. A.L. Becker compares Christensen's and Paul Rodgers' views and discusses their major differences in (1) identity and variation in paragraph recognition, (2) formal markers of paragraphs, and (3) formal correspondence of sentence and paragraph structure. Paul Rodgers, who contends that Christensen's and Becker's theories are limited to certain types of paragraphs, defends his new category, "stadium of discourse," which is designed to cover all possible paragraph variations. In addition to the discussions of these three authors, two other essays are included. David Karrfalt discusses "organic" essays with structure in two dimensions and concludes that Christensen's approach accounts for only one structural dimension--the vertical. In a general discussion of the purpose of discursive prose, Josephine Miles provides a background to the discussion of Christensen, Rodgers, and Becker. (BN)
