Reading "On Revolution" by Hannah Arendt.
There's something charming about a footnote taking up almost the whole page 206. 🙂
That footnote is about the source of authority when a new form of government is formed.
Old: "authority comes from god".
New: authority comes from mutual agreement between groups of people.
That assumption about the source of authority is a key part in the US Declaration of Independence, but existed earlier.
Anyway, I warmly recommend this book.
