Some fifty years ago, Douglas Ainslie wrote of Benedetto Croce: “I can lay no claim to having discovered an America, but I do claim to have discovered a Columbus.” Eric Voegelin, today at the height of his career as a political philosopher, scarcely needs to be discovered; he is regarded as a Columbus in the realms of the spirit by many concerned with the the oretical analysis of politics. But in the political science profession he has been more often ignored or systematically misunderstood than read for what he has to teach. Among those according an indifferent or hostile reception to Voegelin are many who, bewailing the recent “decline” of political theory, might have been expected to welcome the appearance of a thinker meticulously pointing the way to the recovery of political theory as a tradition of inquiry. The basic reasons for this curious reception will be alluded to in the course of this essay. The major objective, however, is to isolate the key elements in Voegelin's political theory and to give some indication of his general position in contemporary political science. Hopefully, the result will be to further the understanding of his work and the appreciation of his achievement.
