Here's a more interesting question: if a political philosopher from the 1860s time-traveled to 2014, how would they view the present? Would they be more shocked by the devastation of the past century or our advanced technology? Would they think that we are closer to the cosmopolitanism envisioned by Kant or the collapse of capitalism predicted by Marx?
I pulled this one from my "Stupid Essay Assignments for an AP European History class" folder.
The paradox is that Karl Marx did not fully discuss the end of the capitalist order until Kapital, which he wrote toward the end of his life in the 1880s.
