Ayn Rand wrote many non-fiction books and essays, as well, but no comprehensive theoretical presentation of her philosophy. The definitive treatment of her thought is Leonard Peikoff’s Objectivism: the Philosophy of Ayn Rand (OPAR). Dr. Peikoff, Ayn Rand’s leading student and long-time associate, wrote an in-depth work in philosophy that is ideal for advanced students; but it was never intended as an introduction to Objectivism. Consequently, a bridge is needed, an introductory text for the millions of readers who love Ayn Rand’s novels and who want to take the next step in understanding her philosophy that will culminate with their study of OPAR.
Objectivism in One Lesson is that text.
...this book seeks to show that Ayn Rand’s philosophy, on every question, topic, and issue, from its commitment to logic to its advocacy of selfishness to its championing of laissez-faire capitalism, to every other, is integrated around one unifying theme: man’s rational mind is his sole means of gaining knowledge, survival, and happiness.It is good to have a third introduction to the philosophy of Objectivism (the other two are Allan Gotthelf's On Ayn Rand and Craig Biddle's Loving Life). I find that a fresh presentation of the philosophy with original examples provides important reinforcement and clarification of the underlying ideas. If the content is as good as Bernstein's previous book, The Capitalist Manifesto, then it promises to be another excellent resource for beginners and experts alike.
