In Search of the Center of European Party Systems

Duverger's famous dictum that “the center does not exist in politics†is the starting point of an inquiry into the possible meanings of the concept of a center, and of center parties, in European party systems. This article consists of six sections; the first five sections deal with the center as a pivot in voting, the center in traditional left-right distributions, the notion of a center in multidimensional party spaces, the center in terms of mechanics, applying rather different metaphors of scales-in-balance and of centripetal versus centrifugal forces, and the center analyzed in terms of social cleavages. Following this search for conceptual meaning, in which the writings of Duverger and Sartori receive particular attention, the record of European party systems is examined to see whether the presence or absence of center parties in party systems can contribute to a realistic classification of European party systems.
