In this article, the authors attempt to provide background for this sp
ecial issue in honor of Harry Eckstein and his work. A brief sketch of
Eckstein's personal life is offered, focusing on his formative experi
ences in Hitler's Germany. The article then turns to an in-depth analy
sis of three of Eckstein's writings: his splendid essay titled ''Polit
ical Science and Public Policy''; his unrivaled overview of the field
of comparative politics in ''A Perspective on Comparative Politics, Pa
st and Present''; and his attempt to redirect the discipline of politi
cal science in ''Authority Patterns: A Structural Basis for Political
Inquiry.'' Eckstein's work holds up well, less in the sense that it ha
s triumphed in the discipline as a whole (both Eckstein and his critic
s agree that it has not) and more in the sense that it serves as a con
stant reference point for an ongoing dialogue about questions that wil
l never be settled.
