Lewis's warnings about the way that science and good intentions have a way of being perverted by the government to become justifications for tyranny and genocide -Hitler's scientific basis for the Holocaust and Stalin's scientific atheism being prime examples - such that horrendous evils can be done with a clear conscience and in the name of the greater good by those in power, the true nature of all governments as de facto oligarchies, the rising threat of technocracy to the liberty and humanity of mankind, the threat to privacy that exists from state authorities, the tendency of people to sell themselves into slavery for the promise of having our physical needs taken care of materially, and the willingness of those in power to promise us anything and everything in order to obtain such surrender and devotion from us, whether they can actually deliver or not are all observations and warnings that don't seem simply prescient to the modern eye, but down right prophetic.
