Hello, Ecopsy,
thank you for this philosophical and neatly formulated question. In fact, no conclusive answers can be given to it, but, personally, I am convinced that civilization and democracy are dissimilar ways of assessing the nature of mankind - civilization is the stage of human social development and organization, while democracy is a system of government, alongside autoritarianism, oligarchy, or technocracy. Roughly, the history of mankind can be divided into the period of barbarism and civilization. The latter is not ultimately positive - the ideologists of the fascist regime, for instance, claimed that Nazism was the highest level to which civilization could be elevated, but we all know that this is blatantly untrue. I would compare a civilization to a large house, in which different families co-exist - some of them are peaceful and democratic, others - aggressive and totalitarian. 'It has been said that democracy is the worst form of government except all the others that have been tried', as Churchill had it. Democracy is not flawless, too, but, as I see it, the concept is more concrete than that of civilization.
Respectfully, Gleb Chebrikoff
