Only in communist society, when the resistance of the capitalists have disappeared, when there are no classes (i.e., when there is no distinction between the members of society as regards their relation to the social means of production), only then "the state... ceases to exist", and "it becomes possible to speak of freedom". Only then will a truly complete democracy become possible and be realized, a democracy without any exceptions whatever. And only then will democracy begin to wither away, owing to the simple fact that, freed from capitalist slavery, from the untold horrors, savagery, absurdities, and infamies of capitalist exploitation, people will gradually become accustomed to observing the elementary rules of social intercourse that have been known for centuries and repeated for thousands of years in all copy-book maxims. They will become accustomed to observing them without force, without coercion, without subordination, without the special apparatus for coercion called the state.
