Some years ago a book entitled The Development of Accounting Thought by Harvey Deinzer was published. It served for us as a textbook, first as students and later as teachers. It was not an entirely satisfactory book especially in that it included in its title, "development", yet seemed more directed to (the then) contemporary accounting thought. We felt another text was needed. One which would utilize a Deinzer-type structure yet be more directed to the actual temporal features process of accounting thought. This aspect, we believe, is important, even crucial, to an understanding of accounting theory (see last Chapter). It was an important element in our accounting theory courses.
