A Memo on My Idea of America
Everyone past the age of reason carries an internal model of the nation where they live. The model describes, with varying complexity and correspondence to reality, the landscape, climate, cultures, history, vibes, and human possibilities and dangers, including what that person believes they can be in relation to their country, and their expectations for treatment by the government and fellow citizens. If enough people talk about their overlapping models, you might get political parties, widespread patriotism, rebellion, nationalism, or talk of a zeitgeist.
