AN INTELLECTUAL ODYSSEY

[L]egislative strategy, which most writers have treated as a mystical art … , may on examination by this [social choice] theory turn out to be a science with quite coherent rules.W. Riker, ‘Voting and the Summation of Preferences: An Interpretive Bibliographical Review of Selected Developments During the Last Decade’, American Political Science Review, 55 (1961), 900–11, quoted at p. 911.

At the most general level there are the things people talk about as possible subjects for group decision. Call this the feasible set. From this misty swamp, politicians – by constitutional restrictions and direction and by rhetorical and heresthetical maneuvers – form the set of considered issues.William H. Riker, Agenda Formation (Ann Arbor: University of Michigan Press, 1993), p. 2.
