  Nowadays the view that Bacon “made little first-hand contribution to science” (Hesse 1964, 152) no longer coincides with the opinion that we have to assume an underestimation of the “place of hypothesis and mathematics” in his work (Urban 1987; Sessions 1999, 139; Rees 1986). But there were few doubts in the past that Bacon “encouraged detailed and methodical experimentation” (Hesse 1964, 152); and he did this on account of his new inductive method, which implied the need for negative instances and refuting experiments. Bacon saw that confirming instances could not suffice to analyze the structure of scientific laws, since this task presupposed a hypothetical-deductive system, which, according to Lisa Jardine, is closely connected to “the logical and linguistic backgrounds from which Bacon's New Logic proceeds …” (Sessions 1999, 140; Jardine 1974, 69ff.).
