Final answer:
Hegel's popularity can be attributed to his innovative ideas, the role of university teachings, the development of his work by subsequent philosophers, and the expertise developed by scholars through repeated study of his complex texts.
Step-by-step explanation:
Despite Hegel's complex writing style, he became popular for several reasons. Firstly, his ideas were innovative and had a deep impact on the philosophy of history, the nature of reality, and political theory.
Hegel's concept of dialectic, the process of thesis-antithesis-synthesis, was particularly influential in understanding historical progress and intellectual development.
Moreover, Hegel's philosophy was extensively taught in universities, which played a crucial role in disseminating his work despite its difficulty.
Additionally, his ideas were engaged with and developed further by subsequent philosophers, ensuring his presence in academic discussions. Lastly, experts who become accustomed to reading challenging texts often do so through repeated reading, which helps deepen their understanding and contribute to the field as notable experts.
