Man tries to make for himself in the fashion that suits him best a simplified and intelligible picture of the world; he then tries to some extent to substitute this cosmos of his for the world of experience, and thus to overcome it. This is what the painter, the poet, the speculative philosopher, and the natural scientist do, each in his own fashion. Each makes this cosmos and its construction the pivot of his emotional life, in order to find in this way the peace and security which he cannot find in the narrow whirlpool of personal experience.

God has a way of standing before the nations with justice and it seems I can hear God saying to America "you are too arrogant, and if you don't change your ways, I will rise up and break the backbone of your power, and I will place it in the hands of a nation that doesn't even know my name. Be still and know that I'm God. Men will beat their swords into plowshafts and their spears into pruning hooks, and nations shall not rise up against nations, neither shall they study war anymore." I don't know about you, I ain't going to study war anymore.
