 Christián Carman worked extensively on the problem of realism in science. He offered a detailed elucidation of the term “scientific realism” (2005a), and he considered the theoretical-observational distinction in light of the problem of realism (2005b). Carman also critically analyzed Harré’s inductive argument for scientific realism (2005c). Moreover, he reformulated the no-miracle argument in order to apply it to simultaneous predictions (2010b), in particular in the context of Ptolemy’s planetary theory (Carman and Díez 2015).
