Looking for evidence

The practice of writing history is an area plagued with errors and difficulties.

There is a well known saying:

History is written by the victors

This indicates the general assumption behind many, if not most, written histories. In hard sciences, theories and hypotheses have to be confirmed by the evidence.

Opposed to this is the common exercise of writing history where theories and grand narratives are first formed. This is followed by collecting all sorts of evidence to match these ‘theories’.

This being the case, in practice, most history books do not stand the test of time. Every few decades, many history books written in the recent past keep needing to be thrown out with only a few exceptions. So one needs to exercise caution.
