 Cicero does not tell us which, if any, of the ethical theories that he discusses we should adopt. Matters are left explicitly unresolved at the close of On Ends (5.95–6). Cicero, however, not only offers us tools to think through the issues for ourselves, but in so doing, utilises the series of expositions and critiques that he lays out to raise pertinent questions, befitting the sceptical stance, about the status of ethical theory itself.
