Our cultural baggage will tend to make us see things differently. An historian from the early 20th century will see things differently from a contemporary historian. A woman will see things differently from a man. This is referred to as the time-bound elements embodied in the historian. We can not help it.
History springs from a live concern, deals with life, serves life.
The way that I examine history to obtain an objective knowledge of the ast can only be attained through the subjective experiences which I have encountered in my life. I can not extinguish the self. As long as we understand what it is we are doing. I tell my students that what I am doing is giving them my interpretation of history, and if they believe everything that I tell them, then they are stupid. In fact if they believe everything that they read they are stupid.
