A second point concerns machines which have the capacity to reproduce themselves. It is our commonly held belief that God made man in his own image. The propagation of the race may also be interpreted as a function in which one living being makes another in its own image. But the author demonstrates that man has made machines which are "very well able to make other machines in their own image," and these machine images are not merely pictorial representations but operative images. Can we then say: God is to Golem as man is to Machines? in Jewish legend, golem is an embryo Adam, shapeless and not fully created, hence a monster, an automation.The third point considered is that of the relation between man and machine. The concern here is ethical. "render unto man the things which are man's and unto the computer the things which are the computer's," warns the author. In this section of the book, Dr. Wiener considers systems involving elements of man and machine. The book is written for the intellectually alert public and does not involve any highly technical knowledge. It is based on lectures given at Yale, at the Société Philosophique de Royaumont, and elsewhere.
