Good titles for posts are prone to pop up in several places, and the same title was used over at Shoutin' Across the Pacific. One thing I would to add to those comments is that once you get into Capitalized Isms, I tend to get somewhat nervous. Too many Capitalized Isms have had pernicious influences throughout history, and that makes hesitant to nail my colors to any Capitalized Mast. Furthermore, the Acolytes of Capitalized Isms in their action define the Ism itself more powerfully than the philosophical underpinnings they may have. The empirical evidence of what the Acolytes actually do is the best indicator of the practical implications and worth of the Ism in question. And that's my problem with Objectivists: looking at how they're behaving makes me unwilling to join them, although in many ways I am sympathetic to the philosophy.
