This essay argues for a method of public engagement grounded in the criteria of ecological validity. Motivated by what Hammersly called the responsibility that comes with intellectual authority: "to seek, as far as possible, to ensure the validity of their conclusions and to participate in rational debate about those conclusions" (1993: 29), organic public engagement follows the empirical turn in citizenship theory and in rhetorical studies of actually existing publics. Rather than shaping citizens into either the compliant subjects of the cynical view or the deliberatively disciplined subjects of the idealist view, organic public engagement instead takes Asen’s advice that "we should ask: how do people enact citizenship?" (2004: 191). In short, organic engagement methods engage publics in the places where they already exist and through those discourses and social practices by which they enact their status as publics. Such engagements can generate practical middle-range theories that facilitate future actions and decisions that are attentive to the local ecologies of diverse publics.
