This podcast is an excerpt from Timothy Snyder's book "On Freedom," which explores the concept of freedom in a contemporary world. Snyder argues that freedom is not merely the absence of barriers (negative freedom), but a positive pursuit of values and action, requiring sovereignty, unpredictability, mobility, factuality, and solidarity. He uses historical examples, including his own experiences in the Soviet Union, and the American Civil Rights movement to illustrate his ideas. He also challenges prevailing ideologies, like libertarianism, and emphasizes the importance of institutions, like local journalism, to safeguard freedom.
