This is spectacular! The Ayn Rand Institute just announced that the Ayn Rand Lexicon is now available online, appropriately enough at AynRandLexicon.com. You can search by key words or explore the alphabetical listing. So, if you ever wanted to know what Rand thought about something, this may well give you the answer.
Just for fun, I clicked on a topic at random. I came up with “Isolationism.” Rand describes one “view of foreign policy which is wrecking the United States to this day: the suicidal view that our foreign policy must be guided, not by considerations of national self-interest, but by concern for the interests and welfare of the world, that is, of all countries except our own.” Her description continues to hold for the foreign policy of the United States.
