That summary is to include his mental and physical state, and the physical and mental characteristics of his environment. (I here use the word "mental" to include everything that is not physical; that is, to include the moral, the spiritual, every influence that does not come under physics or chemistry.) When the investigation of a patient is divided between doctor and social worker, the doctor studies his physique; the social worker studies the rest. I believe that there is nothing that we can want to know about any human being, rich or poor, that is not suggested in that schedule. Suppose, reader, that a friend of yours was engaged to be married. Suppose you wanted to know something about the fiancé. You would certainly want to know about his health and his heredity; then what sort of a person he was, his mentality, whether he had any money--what are the obvious physical facts about his environment. To what influences has he been subjected, and what mental supports, such as education and recreation, family, friends, and religion, can he count upon? You would not want to know any more and you ought not to want to know any less. So in summing up a social diagnosis I think it is convenient to use the four main heads that I have put down here. I think these headings will remind us of everything that we want to put down, and of everything that we may have forgotten to look up. That is one function of such a schedule--to remind us of the things which we have forgotten.
