The study of the past. 'History' is often used to mean 'historical knowledge' when in reality 'history' is the process of researching the past using the available evidence, cross referencing and establishing 'historical knowledge'.
Historians argue about whose interpretation is most valid. These debates often last decades and are only
resolved when either one
side's research is shown to be of poor quality, or when new evidence comes to light proving one interpretation more valid.
Postmodernists argue that history is rubbish because they reckon that it impossible to understand al the motivations of the creator of the
surce material which 'history' uses to
forge historical knowledge. They're wrong.
History: Hey, guys, i went though
the archives and cross reference the kings accounts with his requests for money from
Parliament.
Hitorical Knowledge: Hitler intended for WW2 to start, but not in
1939. His foriegn policy was ideologically driven.
