The latest Enemy of Objectivism is, like most Enemies of Objectivism, a former close associate and orthodox ARIan Diana Hsieh. In fact, the site seems to be really all about this latest schism; the entries on standard villains like the Brandens are meagre and have a pro-forma feel. Hsieh's an odd figure. She was first a Kelleyan Objectivist, then in a dramatic conversion flipped to the Ayn Rand Institute, issuing the required endless blistering denunciations of her former friends and colleagues in the process. Her orthodox enthusiasm later led her to a similarly overwrought denunciation of her former friend and colleague, Ayn Rand scholar Chris Sciabarra. Now the wheel has turned, and it is she who is getting the anathema treatment. As usual, the intellectual content of the charges is close to nil; Hsieh's offending discussions are often breathtakingly inane, like whether it's ethical to eat severely retarded children should the situation require it (FYI, she thinks it is. The correct answer is, of course, let me know when this is actually a pressing problem mankind faces, then we'll discuss it.). The real issue is not anything discernibly to do with philosophy, but instead the fact that she disagreed with, and even worse said Bad Things (such as accusing him of being "horribly ignorant" and "armchair philosophising") about the aging emperor of the ARI.
Of course, almost everyone bar the slavish have immediately twigged that this is simply a shallow, limply conceived hit site. Hsieh has responded at length here, naturally failing to observe the irony that she has been the source of plenty of similar excommunications in the past. But the notable series of schisms over the past few years I would speculate is really just a sign of palace politics, of frantic jockeying for position as Peikoff's frail health and grip on the organisation - and reality - continues to deteriorate. After all, there is some money to be had, some future roles to be played, and some prestige to be garnered, even if it is only within the hermetic world of the Objectivist subculture. And judging by her track record, Hsieh has never needed a weatherman to know which way the wind blows.
