The book purports to be an introduction to "cybernetic medicine" for "those who feel attracted to a really scientific medicine which they so need" (p XIII). There ought to be a better way to introduce the subject. The reader learns little from this book except that there must be a lot of interesting material to be found in the references listed in the bibliography. Not in the text, however ! That is written in the style of a journal article, but in the most extreme sense, so that it is condensed to the utmost, makes only superficial mention of ideas, and leaves the reader to look up the original material in the bibliography.
