A snippet from The Great Liberal Death Wish by Malcolm Muggeridge:
Previous civilizations have been overthrown from without by the incursion of barbarian hordes; ours has dreamed up its own dissolution in the minds of own intellectual elite. It has carefully nurtured its own barbarians—all reared on the best Dr. Spock lines, sent to progressive schools and colleges, fitted with contraceptives or fed birth pills at puberty; mixing D.H. Lawrence with their Coca-Cola, and imbibing the headier stuff (Marcuse, Chairman Mao, Malcolm X) in evening libations of hot chocolate. Not Bolshevism, which Stalin liquidated along with all the old Bolsheviks; not Nazism, which perished along with Hitler in his Berlin bunker; not Fascism, which was left hanging upside down, along with Mussolini and his mistress, from a lamp-post—none of these, history will record, was responsible for bringing down the darkness on our civilization, but liberalism. A solvent rather than a precipitate, a sedative rather than a stimulant, a slough rather than a precipice; blurring the edges of truth, the definition of virtue, the shape of beauty; a cracked bell, a mist, a death wish.
People aren’t all that smart of themselves, though they like to think they are.
