The idea still remains here and there among professional historians. Meanwhile, this part of the discipline became rather dominant in the last decades, fostered by the so-called "memory boom", which gave a new role to historians and other social scientists. Their act ivity isn?t any more the sole research for a better knowledge of the past. They are asked to be stakeholders in the global process of healing or repairing the wrongdoings of history.
