Rand had a Jewish moral and ethical sense. Which is no surprise, since she was brought up Jewish. In her mature years she was no longer observant of Jewish ritual and custom but her grasp of ethics was Jewish down to the "sub-atomic level". One of these days I will write an essay on just how thorough Jewish ideological and ethical conditioning is, even for Jews (like myself) become atheists in their mature years. The ethical "take" that Jewish cultural upbringing produces in virtually indelible. Even today if someone asks me "what are you?" I respond , Jewish, without hesitation or embarrassment, because I am, and I am Jewish because of how I was brought up. Jewish in the cultural, ethical and philosophical sense. So it was with Rand and the most of the first generation Objectivists. Check out her earliest followers. Most of them were brought of Jewish and later in life ceased to be observant.
