This profound book by Youssef Achlhi delves into the intricate relationship between the 'Self' and the 'System' within the philosophical framework of G.W.F. Hegel. It undertakes a critical examination of the fundamental structures that underpin the concept of rationality in Hegel's extensive body of work. Achlhi meticulously questions the foundational elements that grant rationality its specific status and role in Hegelian thought. The work offers a deep intellectual inquiry, pushing readers to reconsider established interpretations and fostering a profound understanding of the complex dialectics at play in Hegel's idealism.
