Lewis makes a point that he believes in democracy because he believes in original sin. He takes this to imply that no men are fit to be masters. However, Lewis’s delusion is that democracy has no masters. This is manifestly false because democracy has always and everywhere produced masters that drove the masses in a particular direction. We can no more eliminate master than we can eliminate sin.
In fact, Lewis’s faith in democracy is entirely contrary to original sin. If we believe in original sin, why would we give even the worst and most repugnant of men equal footing with better men? Since all men tend toward evil as per original sin, why would we entrust government to all men?
This is Lewis’s utopian perspective analogous to Marx though watered down and with a conservative framework. The problem of evil men possessing authority and abusing isn’t cured by democracy. Evil men in authority is no more curable by social structures than sin itself. The mod will and has abused their power and by Lewis’s logic they too have lost their power. We are all born slaves and now not even having the chance of a marginally good master.
