How economic methodology became a separate science

Ever since the formation of the field of economic methodology in the 1990s, doubts have been raised about its discursive closure from both inside and outside the field. Rather than embarking on a programmatic discussion, I present a historical narrative regarding the conditions of the formation of the field, which may have necessitated this closure. These conditions are found in the role methodological reflections played in the formalist revolution of the 1950s and in its critique in the 1970s. Both episodes gave occasion to, but did not require the import of philosophy of science in the mid-1970s. Since the 1980s, when the field became separately established through post-Popperian methodology, it remains an open question whether this imposition still holds.
