This issue highlights the limits of political knowledge, showing why markets better process information than regulators and why calls for government “correction” routinely backfire. Contributors revisit global-warming alarmism, the roots of Arab-Israeli tension, and the implications of restoring constitutional constraints on federal commerce power. Additional articles explore privacy, decentralism, sexual-harassment policy excesses, property-rights parables, historical campaigns for peace and freedom, and the moral framework needed to sustain a free society.
