We know the heads of Marxism are usually Marx, Engels and Lenin, often plus Stalin and Mao.
But who would be the five heads of revolutionary liberalism (before it became a totally bankrupt, anti-emancipatory, status quo project)?
My suggestion: John Locke, Thomas Paine, Robespierre, Toussaint, & Simon Bolivar
Also considered: Oliver Cromwell and Garibaldi
I think Friedman is in the moribund period of liberalism, after liberalism has exhausted it’s revolutionary potential and become largely a force of status quo reaction
