Books like Reason in History

The "greatness" of a nation and the individuals who illustrate this greatness, which, according to Hegel, has only one time and corresponds to a phase of expansion that can not last forever: it is the genius of a nation or people that captures that and brings the human, artistic, cultural, economic, social, legal and "military" qualities of that nation and people to the highest at some point of history, until the time of another people comes, in other geographical areas. Because nothing lasts, and the nation or the people that shone yesterday or who is leading today, tomorrow leave its place to another power, right momentum.Is it a Law of History and a Law of Nature?This is not the place to say whether Hegel is right or wrong, but it must be admitted that the point is interesting.Remember that this theme was the subject of a lecture and the reflection of those who received it could very well feed the thought of the philosopher.
