 The contingent a priori has not been as widely discussed as the necessary a posteriori. The introduction of the contingent a priori is perhaps less surprising than the introduction of the necessary a posteriori, in view of the plausible contingency of a priori statements that philosophers all along recognized, like the plausible contingency of the statement, as uttered in a context, ‘I exist’. Further, Kripke’s examples of the contingent a priori are perhaps more controversial than his examples of the necessary a posteriori. Many dispute that the examples really are examples of the contingent a priori (Donnellan 1977; Hughes 2004, pp. 84–107; Plantinga 1974, pp. 8–9n.; Salmon 1987–1988; cf. Kripke 2019, Other Internet Resources for a defense; Oppy 1994; Salmon 2020 distinguishes an interesting notion related to the contingent a priori that Kripke has allegedly identified). And even if they are contingent and a priori, many feel they lack much significance. They are not “scary,” as Donnellan puts it (also Fitch 2004, p. 121).  On the other hand, confusions are like loose threads: they sometimes work their way to apparently remote material. Confusion about the contingent a priori can and arguably does lead to confusion and apparent paradox in unsuspected areas of philosophy (an alleged example is discussed in LaPorte 2003). Kripke (1980, pp. 14–15) recalls that considerations about the contingent a priori led in his mind to a number of clarifications concerning designation, which again is hardly surprising given the interconnectedness of different issues in a fabric.
