Dan is right on the money, on both counts.
It is a legitimate question to ask: Which of Rand’s writings ought properly to be considered part of Objectivism, and which are her personal opinions or applications of her own philosophy that she would not consider formally to be a part of it?.. A line can be drawn here – where, precisely, is a legitimate topic for discussion.
Dr Peikoff is on record, in the Understanding Objectivism lectures, as agreeing both with the principle and some of the concretes Dan mentions. He has expressly said that matters such as Miss Rand’s position on a woman president are definitely outside the philosophy of Objectivism, along with other particulars such as preference for musicians, ‘sexual style,’ or concrete reactions to the sight of the New York skyline. It’s official - there is a line such as Dan asks about. Some of what Miss Rand wrote definitely is Objectivism, and some is not. Of course, that doesn’t stop Objectivism from being a closed system, as the issue here is only one of sorting out where the boundary actually is.
It doesn’t make any sense for a proper name to refer to a set of ideas that is constantly changing. That would defeat the purpose of giving it a name – the name would serve to dis-integrate the ideas to which it refers, instead of integrating them.
Indeed… which then raises an issue I would be very surprised if it hasn’t been dealt with somewhere else head on: how do we refer to new sets ideas based on Objectivism yet are not within Objectivism itself? Consider the DIM Hypothesis. As far as I know it is Dr Peikoff’s own discovery, so as it is not the work of Ayn Rand it is not part of Objectivism. What is it part of? What are the new ideas formulated by Professor Smith in her book “Viable Values” part of? Dr Buechner is working on his book on economics, based expressly on Miss Rand’s work on value - what of that? Is any integrated system of economic understanding that Dr Buechner may come up with to be known as “The Objectivist School”? If not, then what should it be called - “The Buechnerian School”? (*) And so on…
.. and therein lies what I think half the problem is for honest people who make the error Dan speaks of. To be a conceptual being - especially one who actually thinks conceptually as all Objectivists aspire to do - is to be an integrative being. Those who think and create, especially we Objectivists, will greatly tend to be inclined to integrate their work under a single conceptual reference. People are coming up with new ideas and are presently unable to put a nice tag on their own creations to refer to them with, are then improperly saying it is part of Objectivism, and subsequently getting defensive when rightly told not to do so. In their failure both to understand why and to create their own conceptual references, yet still recognising the need for integration and having such references, they start to think Objectivism being a closed system is to be taken to mean you’re not allowed to think of anything new at all, which any person even partly versed in Objectivist teachings would know is certainly not the case. In response, some reject the fact of the closed system and fall for Kelley’s nonsense, while others accept the fact of Objectivism being a closed-system but then consider Objectivism to be a mindless dogmatic creed. Either way, good people with good minds but used improperly stop being properly Objectivist, and that I hold to be a tragedy. Sometimes they come back to Objectivism, such as Diana, but the core problem is still unaddressed. Therefore, Dan is right - we must address this issue.
The essence of the solution is as simple as I have already indicated. Use Objectivist epistemology to properly integrate your system and put your own label on it to refer to it. By all means, advertise your adherence to Objectivism and your inspiration from Objectivism loudly and proudly, but avoid the temptation to call it part of Objectivism. Reject both the honest error of ignoring the fact of the closed system and the dishonesty of misappropriating Objectivism’s reputation in order to increase your audience.
(* Dr Buechner has actually raised this issue, although only as a particular. In his six-part Objective Value lectures he said that in reference to an idea in economics he presented to his students “Objectivist really means Buechner,” correcting himself in making attributions of origins of the idea he was presenting)
