Dr Taylor (1926 - 2008) was a New Zealand medical practitioner who grew tired of anesthetics being routinely used at childbirth. He developed a program which resulted in all those participating having smooth, drug free natural births.
His theories on birth developed into a theory of mind and a philosophy which he then successfully applied to ordinary arithmetic showing that the theory "added up" literally. The arithmetic is called Circlemaths and opens the door to understanding philosophy, the mind, and funnily enough, birth. He has written many books on all of these subjects.
He is also well known for his 40 day fast against the Vietnam war in the 1970's held in Albert Park.
This book describes how Circlemaths originated, and is replete with philosophy, which runs far deeper than mere calculation. Not a "how to calculate" book, but a book relating philosophy to number. Arithmetic and philosophy become inextricably intertwined in this approach to number.
Doctor Taylor's book on natural birth is not primarily focused on new physical positions or breathing techniques. These are not the problem. Birth is matched by a highly intricate and very delicate psychological mechanism which modern medicine overlooks to its detriment. Understanding that mechanism is the key to correcting it. This includes the theory and practice for obtaining a natural birth.
