The publication Descartes never published and that came out first after his death was called Le Monde or The World. It contained his physico-mathematical world view and featured the heliocentric theory. Galileo was in trouble at the time for this and Descartes decided not to publish. That happens to be the same name as Gideon Rachman used when he recently changed the name of his blog on FT.com. Maybe he also has things that he cannot say until posthumously? The problem of world politics might be in the same developmental level as science was in the 17th century?
