The people in that book, they exist.
It's not so much that they really do live as the book presents them, because genuine daily life is unruly and I'm not so sure that people can get by being so completely an expression of principle as they do, but those guys are real. There's some tendentious near-science to prove it. Oh, I know, this sounds silly, but bear with me. Check out
the Meyer-Briggs Type Indicator. By that account, we have...
Howard Roark: INTJ
Dominique Francon: INTJ
Gail Wynand: ENTJ
Elsworth Toohey: ENFJ
Now, there're different calculations of how many such people exist per population, but generally it appears, they're rare.
One table has it that in one hundred people, you'll find just two or three of each. So there's not a lot of those guys running around, but they're there.
Peter Keating is different. I guess he's ESFP. Per hundred people, and assuming everyone had horrible childhoods and a biographer like Ayn Rand, then there'll be eight or nine like him.
So, how about that? Howard and Dominique are the purest of the bunch, and no one in real life can touch them for rigid splendor, but there are people who, quite naturally, believe as those caricatures do and who attempt to live as they would. It'll take them a beat or two to recognise themselves in print because Ayn Rand hasn't rendered their thinking in very accessible language, but it's there. Gail might be much more easily recognisable. Elsworth is probably a surprise. ENFJ gone bad, or just ENFJ? Not sure.
So... how about that?
To make this China-relevant... in my brief, perhaps sophomoric burst of interest in the MBTI, I think I can fairly say its terms are cross-cultural. Various Chinese I know who've taken a look at their supposed type have discovered things they recognise. So... they're out there. I've met recognisable, and self-tested, INTJs, ENTJs, ENFPs, ENFJs, INFJs, ESTJs; and a bunch of other common folk too.
So... whatcha think? The freakish ideas and lives in that book aren't just anti-socialist polemic. How about that?
Moi? INTJ. Mwahahahah!
