Abstract

That Jean Gayon never paid attention to Darwin’sDarwin, CharlespangenesisPangenesis might seem like an oddity given that natural selectionSelection and biological heredity were his primary focuses for decades. This lack of interest reveals Gayon’s specific methodological orientation: he aimed at producing rational reconstructionsRational reconstruction of the way a scientific hypothesisHypothesis entered experimentation and subsequently evolved within a specific theoretical pattern. Gayon’s most important achievements, Darwinism’sDarwinismStruggle for Survival (1998) in the first place, were all based on this “structuralist approachStructuralist approach (to history of science)”, where philosophy of science provides a strong problematization and even shapes the historical narrative. I argue that LakatosLakatos, Imreand DuhemDuhem, Pierre were Gayon’s main inspirations, and that his work is thereby substantially different from both philosophy of biology andHistorical epistemology French historical epistemologyGayon, JeanOn historical epistemology.
