Explore the dynamics of open and closed systems in government, media, and society through this thought-provoking lecture by Anne-Marie Slaughter, Princeton University's Bert G. Kerstetter '66 University Professor of Politics and International Affairs. Delve into the 21st-century divide between open and closed governments, challenging the traditional democracy vs. non-democracy paradigm. Examine the role of accountability, reader access, and emerging media platforms like Al Jazeera Stream in shaping information dissemination. Investigate the connections between open government, open society, and the open-source movement, and consider how these concepts relate to equality and democracy. Engage with discussions on polarization, politics, and the potential of cyberspace to address societal issues, while also exploring the evolving role of traditional media in an increasingly open world.
