Abstract

Note: This is an article I wrote in 1953. In recent years there have been new developments in the "debate between man and machines." Machines can "understand" what man says and do things according to human commands, facts that I did not know possible at the time. However, I believe that the ideas contained in this article concerning the views that only physical or material forces can effect changes in the state of matter and that there are two kinds of matter do not need to be revised because of these developments. — Author
