Aristotle’s sense of the movement out of dynamis (potential, capacity) and into energia (actuality) was itself ethically neutral, designed to account for a wide range of types of becoming. Yet it also provided a way of conceptualizing the translation of interior states of being into embodied action. Aristotle’s dynamis-energia continuum, along with his taxonomy of voluntary and involuntary behavior, provided the foundational ethical terms by which early moderns negotiated legal cases, theological disputes, and, just as crucially, the regular dilemmas presented by daily social life. Within this context, the Shakespearean stage became a signal space for working out the era’s complicated ways of understanding the move from dynamis to energia as it pertains to intentional ethical action. This chapter focuses on Julius Caesar and Richard II, two plays that take as their central concern the uncertain intentions of potentially rogue agents and the fashioning of multiple forms of community that occurs in response to such ambiguous interior states. By attending closely to the shifts from dynamis to energia within communities as well as individuals – and to variant resonances of these concepts largely lost to modern audiences – Shakespearean drama freshly reimagines classical ethical ideals as a means for fostering communal tranquility within post-Reformation English culture.
