Evolutionary Purpose and Necessity---Machiavelli's Place At the Table. Abstract. While often dismissed as irrational, disingenuous, unethical or “Machiavellian,” game playing strategies and devices are a natural and necessary part of the negotiation and mediation of difficult issues and controversies. If acknowledged and monitored thoughtfully, gaming behavior allows participants a measure of self-protection and provides a lubricant for the constructive, creative and ethical management of complex issues.
