​In recent years, Analytical Eclecticism has emerged as a promising theoretical trend and has attracted great attention from researchers and practitioners of international relations theory. Analytical Eclecticism is based on the following three pillars: the call for theoretical diversity and pluralism by adopting Eclectic methodology; challenging the dominance of classical paradigms (realism, neoliberalism, constructivism) over international relations theory; and to advocate for the replacement of Grand Theory with middle range theories following its decline. The article presents a critical review of these pillars to demonstrate that the rationale upon which analytical Eclecticism is based is tainted by some contradictions; its criticisms of Grand Theory are built on an incomplete understanding of what it and its function are. Moreover, analytical eclecticism is not a new subject in the discipline of international relations, and the decline of Grand Theory does not necessarily signify its disappearance.
