One of the most noted essays of the twentieth century is Quine’s 1951 “Two Dogmas of Empiricism,” which argues the distinction between analytic and synthetic truths, so dear in logical empiricism, is untenable. Necessary truths we have in logic and mathematics cannot receive their necessity of being true merely in virtue of meaning, which is to say, by being analytic truths. Furthermore, for analytic there is no noncircular and enduring rule establishing its extension. A logical truth such as A is identically A, in Quine’s view, need not get its truth only by our say-so meaning of is identically, but could as well get its truth by its capture of the way the world is (Quine 1954, 113).
In his 2016, Greg Salmieri notes that it is curious that Peikoff 1967 does not mention Quine’s “Two Dogmas.” Salmeiri points out some ways the Rand-Peikoff diagnoses of and remedies for the errors in analytic-versus-synthetic doctrines differ from Quine’s. Salmieri understands the later challenge of AvS from Kripke and Putnam to have more in common with the Objectivist challenge, though Putnam differs importantly from Rand on definitions and essences, which looms large in the Objectivist challenge (2016, 304n34, 311n87). Salmieri points to the book-review article, in JARS in 2005, by Roderick Long for thoughts on some relations between Randian theory of meaning and those of Kripke and Putnam.
Long’s 2005 review of Greg Browne’s book Necessary Factual Truth was followed a year later by a substantial reply from Browne and rejoinder by Long (JARS V7N1). From May to September of 2007, Prof. Browne engaged in a very generous exchange (his own words coming to about 19,000) in a thread at Objectivist Living defending the rejection by Peikoff of AvS and defending his own kindred rejection of AvS. Browne had in his arsenal the Kripke-Putnam developments that had been savaging AvS in the years since Peikoff 1967. Browne vigorously countered, in that thread, devotees of Logical Empiricism (and of Popper) who criticized (and poorly understood the revolution afoot, such as in) Peikoff 1967.
Late in that thread, Robert Campbell entered it only to ask Browne if he had any thoughts on why Peikoff had not addressed the famous Quine paper in his Peikoff’s dissertation, which Campbell had lately acquired. Browne had not seen the dissertation and had not much to conjecture on that peculiarity. (Peikoff 1964 is not written as a champion of Ayn Rand’s philosophic views, but, in an even-handed way, by an author acknowledging his background preference for some rehabilitated sort of logical ontologism and pointing near the end of the dissertation to some of that rehabilitation, such as fresh thinking on the nature of definitions and essence; distance between Quine’s views on logic and on AvS and Randian Peikoff views would not be the reason for no Quine in Peikoff 1964.) I should suggest that Quine, Carnap, Russell, and Wittgenstein raise such a briar patch of technicalities that it was better (and enough for deserving a Ph.D.) to stick with the more accessible and manageable Ayer, Nagel, Dewey, and Lewis to get the dissertation (already more than an armful in history assimilated) finally completed.
