This lecture previews a forthcoming volume of Ayn Rand's journals, edited by Mr. Harriman. Miss Rand wrote the journals to herself for the purpose of clarifying her literary and philosophic ideas. The journals begin in 1927, when she was writing scenarios for Hollywood, and extend through the 1960s; they include lengthy notes on The Fountainhead and Atlas Shrugged, as well as notes on four books that she planned but never wrote. This lecture will discuss some highlights from the journals, with a focus on Ayn Rand's method of "chewing" ideas, on her ability to see the widest philosophic abstractions in everyday concretes, and on aspects of the chronological development of the ideas in her novels and philosophy.
