It is the author?s intention to explore the realist theory in International
Relations in the context of Imre Lakatos?s Methodology of Scientific Research
Programs. To this end, after defining the notion of realism in IR and
exposing the foundations of Lakatos?s analytical pattern, relevant findings
of several authors who took part in the debate on this issue from the area of
philosophy of science (John Vasquez, Kenneth Waltz, Stephen Walt, Thomas
Christensen and Jack Snyder, Colin Elman and Miriam Fendius Elman, Randall
Schweller, William Wohlforth) will be presented and critically analyzed. In
that sense, there are two key lines of dispute: about whether Lakatos?s
methodology is properly utilized in evaluating realist theory, and whether it
represents an adequate tool for such a metatheoretical endeavor in the first
place. In the concluding part of the article, author?s findings which point
toward tenability of the realist research program, along with a limited scope
of applicability of Lakatos?s methodology in the field of International
Relations.
