Political Leadership in Modern Europe: Reason of State and Prudence

Abstract

This study examines political leadership in modern Europe through the relationship between reason of state and prudence. Reason of state prioritizes the state’s survival and strength, but separated from moral responsibility it can degenerate into the unrestrained pursuit of power. Prudence is defined here as a leader’s capacity for practical judgment that directs the interests of the state toward morality and political legitimacy. Its core lies in self-restraint: limiting one’s own convictions, emotions, and desire for power for the sake of the community’s long-term interest. Reason of state guided by such prudence is conceptualized as “good reason of state,” identified by three criteria: long-term survival of the political community, service to public rather than personal interest, and restraint in the costs imposed on others. Three cases illustrate this. Henry IV subordinated his religious convictions to the kingdom’s preservation through his conversion and the Edict of Nantes. Elizabeth I turned the vulnerabilities of an unmarried female monarch into political resources through symbolic politics and marriage diplomacy. Bismarck, defining Germany as a “satiated state” after unification, restrained the expansionism that victory had generated. Together they show that political prudence consists not only in determining what must be done but also in discerning what must not be done. Reason of state need not operate solely as a ruthless technique of power; guided by self-restraint, it can be realized as “good reason of state.”
