Informative and enlightening, in Cicero's New Leadership Evan R.W. Dutmer explores an important ancient predecessor to mainstream leadership studies research. Using Marcus Tullius Cicero's On the Republic as a point of departure, Dutmer connects its vision for leadership with contemporary parallels, examining key virtues beneficial to both individuals and societies.Dutmer introduces the term 'proto-transformational' to categorize Cicero's leadership theory, addressing the ancient biases present in his idealized leadership portraits. The book outlines how Cicero's ideal leaders are both ethical and effective: they act as authentic transformational leaders, selflessly serving the common good while demonstrating virtuous integrity in their words and actions. Dutmer also highlights how Cicero's model, which centers on the practice of the Cardinal Virtues, aligns with current character-focused leadership development frameworks. Chapters address the emerging developments in two crucial movements in modern leadership studies: transformational leadership and Leadership for Flourishing.This book is an essential read for scholars and students of leadership theory, ethics, political science and political philosophy. By establishing Cicero as a significant leadership thinker, it will also appeal to those interested in applying such concepts to debates and areas of practical importance within law, religion and constitutions.
