This study presents a compelling reflection on the historian's task. Based on his extensive teaching and research experience as well as his rigorous analysis of historical scholarship, Professor Bernardo Ares's study of history sets historical knowledge against the general framework of scientific knowledge. Supported by a thorough definition of the concept of history, Historiology, Research and Didactics focuses on the basic epistemological and methodological questions involved in the study of history, and provides a unique analysis of the didactics of history. Stressing the importance of historic information and formation for the transformation of the individual, as well as society, toward genuine humanism, Professor Bernardo Ares's insights into the theory of history will be of great interest to both historians and educators.
