I believe the question here is, at what point and under what circumstances can a person legitimately make the claim that they are Objectivists.
As Melchior noted, it’s a closed philosophy. In order for some statement or argument to be considered Objectivism, it would have to be demonstrably in accord with something Ayn Rand posited herself as part of Objectivism, or was posited by someone else and approved by her. But the question at issue here is not whether an idea is Objectivist, but whether an individual is an Objectivst.
I see the following possibilities:
- A person precisely agrees with Ayn Rand and hasn’t in any way, shape or form considered topics beyond what she has considered. This is a null set of people, at least since 1982, and I suspect Rand considered some things and never wrote about them, so even there I suspect she wouldn’t be part of this group were she still alive.
2a) Someone agrees with some parts of it, and hasn’t thought at all about other parts, but has no actual disagreements so far. This person is a potential Objectivist.
2b) Someone agrees with some parts, and actively disagrees with others. This ranges from NO to HELL NO. And that NO, if it’s truly a side issue the person disagrees with, may even be a maybe (e.g., if someone disagrees about the particular nature of “instinct” and “volition” but still agrees that man is the rational animal and must use his rational faculty to survive, he will still arrive at the Objectivst ethics). But Kelley and Branden are definitely HELL NO grade 2b cases.
3a) Someone agrees with Objectivism, and has added on to it–considered issues that Ayn Rand has not considered. Ayn Rand herself, I believe, expected that this would happen. Assuming the add-on doesn’t contradict, I would call this person an Objectivist, provided of course that they do not insist on regarding their extension as being part of, rather than a consequence of, Objectivism.
3b) Covers the case of an invalid (contradictory) extension of Objectivism. This will reduce to either 3a or 2b once the person resolves the contradiction–and in many cases the person *has* implicitly resolved the contradiction, in favor of their extension and they are already in group 2b.
[…and yes for the curious I chose my example about instinct and volition because it is the biggest issue I am aware of that I must resolve. Though I am probably weak in epistemology as well. Conversationally I will tend to casually group myself in with Objectivists, since no outsider would ever notice the difference, but when being very careful, leave a little distance.]
