A prolific writer, bestselling novelist, and world-renowned philosopher, <b>Ayn Rand</b> defined a full system of thought--from epistemology to aesthetics. Her writing is so extensive and the range of issues she covers so enormous that those interested in finding her discussions of a given topic may have to search through many sources to locate the relevant passage. <b>The Ayn Rand Lexicon</b> brings together all the key ideas of her philosophy of Objectivism. Begun under Rand's supervision, this unique volume is an invaluable guide to her philosophy or reason, self-interest and laissez-faire capitalism--the philosophy so brilliantly dramatized in her novels The Fountainhead, We the Living, and Anthem.
