True, but has it not always been the case that writers have tended to view the past through a lens shaped by their contemporary mores? When I studied history (we used Books -- it was that long ago) I was taught that the development of arguments about a historical thing was part and parcel of the knowledge of that thing (rather like the article suggests). The critical evaluation of historiography must take into account the prevailing attitudes of the time as well as any other political biases. Reading around helps to elucidate these, so crucially one never relies on a single source.
