: The study of perfection, progress and evolution is a central theme in the history of ideas. This thesis explores this theme seen and understood as part of a discourse in the new fields of anthropology, sociology and psychology in the nineteenth century. A particular focus is on the stance taken by philosophers, scientists and writers in the discussion of theories of human physical and mental evolution, as well as on their views concerning the nature of social progress and historical (...) change. The wisdom and feasibility of improving the human species is discussed alongside an analysis of new methods of investigating and measuring physical and mental attributes of the human organism.The instruments used to assess the development of mind, body and society are described, and are viewed as part of an increased emphasis on the use of technology as an integral part of modern life, and as a means toward the ordered gathering of information in social-scientific practice. An international perspective is taken by observing the way in which ideas about the physical and mental development of humankind was discussed in light and consequence of English and European scientific exploration in the Southern Hemisphere. Further, an evaluation is made of the manner of the spread of new thought in the social sciences from the intellectual and cultural 'centre' of England and Europe to the Anglo-European community located at the 'periphery' in Australia in the late nineteenth century. In particular the educative role played by the non-professional enthusiast as a pivotal conduit for the dissemination of these ideas is highlighted and linked back to a significant tradition of amateur scholarship as a central phenomenon in the study of the history of ideas.

Human genetics research appears to be approaching a period of re-examination due to the decades-long failure of molecular genetic research to uncover the genes presumed to underlie psychiatric disorders, psychological traits, and some common medical conditions. As currently dominant theories of genetic causation come more into question, we will see a renewed interest in reassessing the potential roles of genes and environment in these areas. To illustrate the potentially harmful and diversionary impact of emphasizing genetics over the environment, the author (...) tells a story in the form of a parable. In this parable, the citizens of a medium-size city are confronted with the task of dealing with a group of arsonists who are systematically burning down several houses each week. The Mayor argues that the best way to prevent arson is to analyze the types of wood used to build the city’s houses, with an accompanying lack of interest in arresting the arsonists. Her opponents argue that regardless of the type of wood used, the city and its citizens should prevent arson attacks by focusing attention on identifying and arresting the arsonists. The Mayor’s position prevails, and the arson attacks continue for years to come at the same time as researchers continue to study and analyze the wood used to construct the houses. Informed readers will recognize the analogous ideas, research strategies, interest groups, publications, and historical controversies related to “nature–nurture” issues, which encompass every aspect of the parable.
