This article explores how gender and race infused meanings of the key concepts of virtue and passion in the writings of Simón Bolívar (1783Bolívar ( -1830. Even when coding dangerous passions as feminine, Bolívar was chiefly concerned with masculinity. Influenced by European moral philosophy, he believed that the passions of vengeance, jealousy, and ambition, which held sway over weak civilian politicians and ambitious men of colour, gave rise to political factions that threatened national order. His solution was to inculcate republican morality in the citizenry through institutions such as a hereditary senate, a moral power, or a chamber of censors. Such political ideas and models of masculinity, rooted in classical republicanism, differed from liberalism's faith that if men were free to pursue their economic interests, the passions would neutralize each other. Although Bolívar's most radical proposals were not enacted, his moralizing goals were widely shared and shaped Spanish American political traditions.Usurpations by the rich, robbery by the poor, and the unbridled passions of both, suppressed the cries of natural compassion and the still feeble voice of justice, and filled men with avarice, ambition, and vice. (Rousseau 1973: 87) In all very numerous assemblies, of whatever characters composed, passion never fails to wrest the sceptre from reason. (The Federalist No. 55, in Hamilton, Madison & Jay 2003: 270) Cuando los sucesos no están asegurados, cuando el Estado es débil, y cuando las empresas son remotas, todos los hombres vacilan; las opiniones dividen, las pasiones las agitan, y los enemigos las animan para triunfar por este fácil medio. (La carta de Jamaica, Bolívar 1984, I: 174)
