The idea which...shuts out the Second Coming from our minds, the idea of the world slowly ripening to perfection, is a myth, not a generalization from experience.
C. S. LewisOne of the most dangerous errors is that civilization is automatically bound to increase and spread. The lesson of history is the opposite; civilization is a rarity, attained with difficulty and easily lost. The normal state of humanity is barbarism, just as the normal surface of the planet is salt water. Land looms large in our imagination and civilization in history books, only because sea and savagery are to us less interesting.
