 Though Goodman thinks justification of our reasoning practices depends on what inferences we accept when we reason inductively and deductively, he is not simply seeking to systematize whatever inferences we happen to find people sometimes—unreflectively—make. Instead, he insists that practice can and should be corrected as we work back and forth from tentative principles to practice, revising where appropriate, presumably eliminating the sorts of inconsistencies that some psychological studies, and our everyday experiences, reveal. But, some critics ask (Siegel 1992), if practice should be revised, why should we view “fit” with practice as at all justificatory?
