It recounts events with careful attention to their importance, their mutual relations, their causes and consequences, selecting and grouping events on the ground of their interest or importance. It can be seen from this that history acknowledges the existence of events and facts and seeks to understand how they came about, what they resulted in, how they are interconnected and what they mean. The distinctions need to be made among facts, analysis and interpretation. Facts are demonstrably empirical events whose occurrence can be proven using evidentiary methods. Analysis is the method of determining or describing the nature of a thing by resolving it into its parts.
Interpretation is the attempt to give the meaning of something.
It follows that facts lead to analysis which leads to interpretation. And it follows that each step in the process is more subjective than the preceding step. In this context, history is inductive in its methodology, in that it accumulates the facts, tries to determine their nature and their connectivities and then attempts to weave them into an understandable and meaningful mosaic. On its basic level, revisionism is nothing more than than the advocacy of revision, which in itself is the act of revising, or modifying something that already exists. Applied to history, it means that historians challenge the accepted version of the causes or consequences of historical events.
