The Objectivist movement has helped many people apply Objectivist principles to their personal lives; it has contributed to the broad-based political movement for liberty; and it has sponsored research on the philosophy of Objectivism itself. Yet people and groups within the movement differ on a number of issues. This panel, concluding the Atlas Summit conference, will discuss what is closed and what is subject to change in the philosophy, and what kind of intellectual culture is required to help a distinctively Objectivist school of thought to grow and thrive without betraying its core principles. Participants include David Harriman, David Kelley, and TAS chairman Jay Lapeyre.
