The 250th anniversary of the Declaration of Independence offers an opportunity to reflect not only on America’s founding, but on the ideas that made independence intelligible and self-government sustainable. Liberty Fund is marking the occasion with essays, conversations, and resources that examine the Declaration as a statement of principles, one concerned with moral authority, lawful resistance, and the careful balance between liberty and order. This week’s selections explore how those ideas continue to shape the character, institutions, and responsibilities of a free society two and a half centuries on.
