 More than a century after Duhem argued for his non-falsifiability thesis, the set of issues connected with it are still elaborated upon, criticized, and defended in the large literature on the philosophy of science. Given holism, non-falsifiability follows logically and thus, when an experiment goes wrong, there is no set way to determine which hypothesis among many hypotheses is defective. Duhem proposed bon sens as a resolution to the problem, but that solution seemed unsatisfactory to many: it looked more psychological than epistemological and it sounded too vague. Thus scholars attempted to articulate further what Duhem might have meant as bon sens (see Ivanova 2010, Kidd 2011, Ivanova 2011, and Ivanova and Pasternote 2013). Others proposed their own resolutions to the problem, attempting to isolate defective hypotheses by extra-logical means, whether by inference to the best explanation, Bayesian devices, error-statistical methods, or though elaborate experimental practices; for an analysis of such solutions, see Dietrich and Honenberger 2020 or Ivanova 2021).
