Because the past is complicated and difficult to understand in many cases, I make the history of reconstruction a rewarding work. When trying to group the past, historians may primarily encounter many problems with respect to resources - information that historians use to gain the past. Among these problems, the most prominent include reliability, bias, and lack of source information. These problems only complicate the process of accurately reconstructing the past.
Of course, historians are interested in the credibility of the historical story, that is, the past "objectivity". Historical conscience will rebuild the past based on evidence and try to interpret historical data exactly. Mead's view is that all these reconstructions and interpretations of the past are based on the open reality of the future, the temporal conditions and interests of historical thinking are purely "objective" historical Making it impossible to build records. Historical consciousness is "subjective", which is intended to explain the past with human significance in the present and foreseeable future. Therefore, for Mead, historical exploration is an imaginative but sincere, intelligent and understandable human past reconstruction and interpretation based on all existing related evidence.
Another problem hinders accurate understanding of the past. An attempt to understand history is a unique effort of mankind. The interpretation of the past differs from culture to culture and changes with time in a specific society. In the present Western historical tradition, the interpretation of the past has changed due to changes in social view. Generation values and attitudes are not necessarily shared with others. Despite these differences in the context of interpretation, their efforts to rebuild and understand the past provide historians with current values. By analyzing and interpreting evidence through academic networks, sharing and criticizing each other, historians can better understand the past, as well as better understand the relationship between today and the past.
