This article investigates the educational philosophy of the 16th-century Korean Neo-Confucian scholar Yi Yulgok (1536-1584), evaluates its contemporary relevance through an analysis of his seminal text, Gyeongmong yogyeol (The Secret to Banishing Ignorance), and concludes with an autoethnographic reflection by the author. This argument is grounded in a methodology that combines textual analysis of Yulgok’s primary writings with biographical-historical contextualization, complemented by autoethnographic reflection on fifteen years of teaching this philosophy to a global student body. The analysis traces this holistic perspective to the foundational influence of Yulgok’s mother, Sin Saimdang, whose progressive pedagogical methods—emphasizing empirical observation and self-directed inquiry—cultivated the pragmatic, interdisciplinary mindset that allowed him to integrate Confucian principles of benevolence (in 仁) and virtue (deok 德) with the practical challenges of statecraft and social ethics. Ultimately, Yulgok's holistic educational model, which inextricably links internal moral cultivation with external public service, offers a potent corrective to the compartmentalization prevalent in modern higher education, advocating for the cultivation of an ethically integrated public intellectual.
