A new ‘political philosophy’ is indispensable to the ‘post-Corona world,’ and this paper tries to analyze the future of ‘liberal democracy’ in it. It shows that ‘liberal democracy’ faces a ‘global crisis’ that has begun before, but the ‘novel Coronavirus pandemic,’ as a setback for it, strongly encourages that crisis. ‘Liberalism’ and ‘democracy,’ which had long been assumed by ‘political philosophers’ to go together, are now becoming decoupled, and the ‘liberal values’ of ‘democracy’ are eroding. To find why and how, this paper analyzes ‘authoritarianism,’ ‘totalitarianism,’ and the evils and propensities of ‘democracy’ that bring about further erosions of ‘liberal values.’ There may be difficult trade-offs to be made between ‘liberal’ and ‘authoritarian’ ‘values’ - and, after the experience of ‘Coronavirus,’ this paper shows the ‘illiberal or authoritarian democracy’ may become stronger.
