Positive arguments on behalf of passion are scarce in liberal political theory. Rather, liberal theorists tend to push passion to the margins of their theories of politics, either by ignoring it or by explicitly arguing that passion poses a danger to politics and is best kept out of the public realm. The purpose of this essay is to criticize these marginalizations and to illustrate their roots in impoverished conceptions of passion. Using a richer conception of passion as the desire for (...) an envisioned good, I argue that it is neither possible nor desirable to eliminate passion from politics. Passion should therefore be established as a central category of analysis in political theory alongside other key concerns. Key Words: passion • reason • politics • liberalism • eros. (shrink)
