For the 25th anniversary issue of "English Teaching Forum," published in 1987, the author wrote about the diversification of the language teaching field. Her point then was that during the preceding years from 1962 to 1987, the language teaching field had diversified: Where earlier there had been a unified approach to language teaching, by 1987, many options existed. Today, as she writes on the occasion of the 50th anniversary of "Forum," the author perceives a different pattern. She sees diversity "within" unity, not as an alternative to it. She begins this article by briefly summarizing the main theme of her 1987 article. Next, she turns to the triangle that she used then to depict the language teaching field. In each of the three angles of the triangle, she placed the major categories of language/culture, language learners/learning, and language teachers/teaching. In this article, the author revisits each of the angles, making observations that support her contention that today there is diversity within unity. She concludes by stepping back from this analysis of the field and by stating why she feels that the theme that she has chosen for her article in this 50th anniversary issue is important to everybody.
