The Universal Constant in Living was Alexander’s fourth and last book. It contains his most mature and consummate thoughts on what is now known as the Alexander Technique. Alexander shares with the reader knowledge accumulated in the course of more than 45 years of practical teaching experience. Having fully developed the concepts of his technique, he presents a clear exposition of the fundamental principles: prevention (inhibition), the primary control of use, and the unity (wholeness) of the human organism, among others.

This is 'White Edition'. The white paperback books contain the essential texts: they are almost identical to the last editions Alexander was responsible for in 1945–46: the complete text of the books with the forewords and introductions published at the time (for example containing Dewey’s or Coghill’s introductions, and Alexander’s forewords and Alexander’s new forewords.)

The difference between the ‘cream’ and ‘white’ editions of Alexander’s books is that the white paperbacks do NOT contain:
Walter Carrington’s and editor’s forewords; notes on the text; endnotes; appendices or any photographs added since 1945–46 editions; index. For these please consult the ‘cream’ editions.
