Helmut, List: According to Peirce, within the specific context of retroduction, a conjecture or hypothesis is *plausible *whenever an inquirer is led to regard it with favor; and "this acceptance ranges, in different cases,--and reasonably so,--from a mere expression of it in the interrogative mood, as a question meriting attention and reply, up through all appraisals of Plausibility, to uncontrollable inclination to believe" (CP 6.469, EP 2:441, 1908). Rather than Ockham's razor, he connects it with Galileo's *il lume naturale*, according to which "of two hypotheses, the *simpler *is to be preferred"--not "the *logically* simpler" in Ockham's sense, "the one that adds the least to what has been observed," but "the simpler hypothesis in the sense of the more facile and natural, the one that instinct suggests" (CP 6.477, EP 2:444, 1908).
