The Internet hosts many critiques of Objectivism, the philosophy of Ayn Rand, most of which are useless or worse. Michael Huemer’s Why I Am Not an Objectivist (WIANO hereafter) is an exception. It has the great virtue that any Objectivist who engages its arguments can either realize a better understanding of philosophy by overcoming them, or else realize the inadequacy of his understanding by failing to do so.
What follows is a rejoinder to WIANO’s first section, “MEANING.” This is the first revision of a version published earlier here.
Huemer Against Rand on Meaning
Objectivism rejects the analytic-synthetic dichotomy. Michael Huemer accepts it. He correctly recognizes that the basis for Objectivism’s rejection of this dichotomy lies in its identification of the meaning of concepts. Leonard Peikoff writes, in “The Analytic-Synthetic Dichotomy,” “[A] concept means the existents which it integrates. … [It] subsumes and includes all the characteristics of its referents, known and not yet known.” (Introduction to Objectivist Epistemology, Second Edition, p. 99. Emphasis in original. Hereafter cited as ITOE.) Huemer also notes that Objectivists consider concepts to be open-ended, or as he would have them put it, “[T]he meaning of a concept is all of the concretes it subsumes, past, present, and future, including ones that we will never know about.” (WIANO, §1)
Huemer prepares his attack on the Objectivist rejection of the analytic-synthetic dichotomy by reference to the story of Oedipus, who famously — and unwittingly — married his own mother, Jocaste. Huemer wants to show that the Objectivist theory entails that Oedipus could not have married his own mother unwittingly, since he knew that he was marrying Jocaste, and since “Jocaste” and “Oedipus’ mother” have the same referent. It is absurd to think that Oedipus knew he was marrying “Oedipus’ mother” just because he knew he was marrying “Jocaste,” so if Objectivism does entail this, Objectivism is absurd.
