This dictionary provides detailed analysis of over half a million lives, including relevant personality traits, as well as quotes from documents alluding to the protagonists, the most important events in their careers and on several occasions, a moral assessment of their acts. By going deeper into the lives of people who lived through such difficult times, there is an inevitable extraction of the true essence of virtue and vice, good and bad. There is no relativism. In this way, and without this work aiming to be a tract of moral philosophy, it can be of use to us in concluding that there are some undoubtably good actions and others that are undeniably bad. Not everything is relative. The best way to fight tyranny in a dialectical fashion is to understand it. To learn from those who bravely opposed Nazism even by giving up their own lives is also a way of defending their dignity.
