In 1377, during an intellectual retreat from the turmoil of political life in a very critical and precarious moment in history, Ibn Khaldun -- Tunisian protosociologist and historian -- wrote the massive seven-volume history called Kitab al'ibar (book of lessons from history). This paper stresses that an important function of Ibn Khaldun's revolutionary work -- setting the history of civilizations within the frame of rational schemes where it is subject to regular laws akin to those of physics-- must have been a legal and political one: to prod the rulers of his time to be more responsibly aware in their political and legal action, tilting such action in favour of the preservation of social cohesion, understood as key to the very survival of a given civilization.
