This article examines the often-overlooked role played by classical dialectics in managerial discourse, highlighting its enduring relevance in business communication instruction. Through comparative analysis, the article shows how Peter F. Drucker’s management theories draw on classical dialectics and how an applied liberal arts approach can inform interpersonal workplace dialogue and strengthen managerial effectiveness. The analysis suggests that, through the Druckerian lens, classical dialectic effectively bridges practical wisdom ( phronesis ) and action ( praxis ) in management. The article concludes that incorporating classical dialectics into business communication curricula and training can enhance modern management education.
