Exit from Our Age of Disorder with Lessons from Ibn Khaldun

Rate this book
From the celebrated author and politician Bruno Maçães, Exit explores the breakdown of the existing global order. Starting from the insights of historian and philosopher Ibn Khaldun, Exit explores how that breakdown is expressed in growing conflict, destruction and intellectual confusion. It offers a guide into how to approach the transition to a new kind of order, and the hard task of building it from the ruins of the present.

Exit also serves as one of first works of the newly founded Ibn Khaldun Institute. Ibn Khaldun, (Abu Zayd Abd ar-Rahman ibn Muhammad ibn Khaldun), was one of the most prominent historian, philosopher, and scholar of the Middle Ages. He was born in May 1332, in Tunis, and passed away in March 1406, in Cairo.

Ibn Khaldun is best known for his ground-breaking work, "Muqaddimah" (also known as "The Introduction" or "Prolegomena"). With a multidisciplinary approach to the study of societies, Ibn Khaldun developed his ‘new science’ (umrān) – a positive rather than a normative study of state and society as they are, rather than as they should be. This methodology allowed him to identify and characterise sociological and economic phenomena centuries before these ideas were developed in the West. He developed the concept of ʿasabiyyah – the importance of social cohesion in avoiding civilisational decline. Above all, his elegant contributions to economics included some of the earliest known descriptions of the multiplier effect, human capital, the effect of technological improvements on growth, supply side-economics and the Laffer Curve.

Ibn Khaldun Institute is committed to preserving, promoting, and perpetuating the legacy of Ibn Khaldun, transforming his ideas into a powerful force for positive change and a source of inspiration for generations to come. Together, we strive to create a global community that values the wisdom and vision of this exceptional scholar, characterized by free trade, property rights and the rule of law.

The book - or rather the short essay - is a relatively disappointing and rather incoherent mish-mash of Mr Macaes X feed. Evoking Ibn Khaldun is thought-provoking and I agree with Mr Macaes that his insights remain relevant today.
But the book has an excessive Western animus and fails to build on its central sections. Its final 'fundamental principles of world order' are remarkably shallow. I don't think this essay will have a long shelf life.
