From the previews of the forthcoming bio by Anne Heller, "Ayn Rand And The World She Made" the basic thesis seems to be that Rand gradually invented her own reality; that she came to live in a kind of solipsistic world of her own.
If this is the case, I would agree. This solipsism is a natural consequence of her theories combining egoism and introspection, despite the lipservice Objectivism pays to attending to reality. What's interesting is tracking down some of the mechanisms by which she gradually erodes the real world and replaces it with one of her own making, as this replacement of reality with a novelised fantasy as a superior reality is one of what I've dubbed the "cultic incitements" in her work.
Here's one very subtle, but very telling example, from her second interview with Phil Donahue. At about 1:58 in the clip above he quizzes her about what she means by a "sacrifice" and here's what she says:
Rand: What I mean by "sacrifice"... and what is generally meant (DB emphasis)...is to give up some value that is important to you for something else that is a lesser value...or a non-value...Now, ARCHNblog readers may be familiar with our Understanding Objectivist Jargon series, where we explain the odd and often highly twisted meanings that Rand attached to many common terms. In fact, Rand's version of "sacrifice" is the exact opposite of the general meaning of "sacrifice", which is giving up some lesser value for a greater value.
Yet in the version of reality Rand lived in her own, invented meaning was the one that was "generally meant".
Like her crucial falsification of the dictionary definition of "selfishness" in her introduction to "The Virtue of Selfishness", Rand seems to be not so much dishonest as semi-delusional. Like a kind of postmodernist, the words make up her world.
