Indeed for Rousseau, we are free, sovereign, and self-legislating only when we join with others to set the terms by which we live together. Those who remain slaves to instinct or to individual interest forsake both freedom and humanness as they surrender this sovereignty over themselves. For Rousseau, humans are the only creatures capable of generating complex orders of domination from their needs, of enslaving themselves by giving free rein to homo oeconomicus, by letting it overtake their personalities, social relations, and politics: this is the essence of Rousseau's critique of emerging liberalism. Thus, for Rousseau the deliberate and fierce cultivation of homo politicus (and it is most definitely not homo juridicus or homo legalis) is the only antidote to this peril. Homo politicus—understood as self-sovereign through collective sovereignty — must literally subdue the creature of self-interest and self-absorption. Otherwise, we not only fall into egoism, narcissism, and superficiality, but are dominated by the social relations and regimes generated by unbridled interest.
