How do we judge viewpoints — political movements, ideologies, philosophies — that seem to contain mixtures of good and bad ideas? How do we determine whether any specific element of a broader framework is good or bad? This talk discusses a range of viewpoints, from environmentalism to religion to Black Lives Matter, and examines the means by which their concrete positions should be assessed. It explains how to identify the fundamental of any systematic viewpoint, and how that must shape our judgment of those concrete positions. Recorded live on July 7, 2022 as part of the Objectivist Summer Conference.
