The purpose of a book by Paolo Riccardi on Anthropology and Pedagogy is to 

 show wbat aid anthropology can bring to the science of education. The school, 

 according to his view, should not be regarded as an assemblage of children of 

 every class, connected with one another only by the four walls of a common in- 

 closure ; but as a social organism, a little society in which the child is to be taught 

 to live, and prepared for the future life in the larger society of adults. He asks 

 anthropology to make this preparation. The teacher's first effort should be to 

 determine the relative strength of his pupils, and the possible relations between 

 superior and inferior vigor and intelligence, between the moral and the organic 

 condition of each.
