Ayn Rand’s novels The Fountainhead and Atlas Shrugged gave birth to a movement based on her philosophy of objectivism. In The Contested Legacy of Ayn Rand, philosopher David Kelley explains why he broke ranks with orthodox objectivists and created an independent branch of the movement. Originally published in 1990 as a manifesto, the work was revised in 2018 as an analysis of the principles of the intellectual collaboration, toleration, and responsibility. It is an engaging introduction to the objectivist movement, its core ideas, and its central fissures. At the same time, it offers a case study in the sociology of intellectual movements and a frank discussion of the issues that arise whenever thinkers leave their studies to promote their ideas in the public realm.
