Read this passage from "the american dream."through our scientific genius we have made of this world a neighborhood; now through our moral and spiritual development we must make of it a brotherhood. in a real sense, we must all learn to live together as brothers, or we will all perish together as fools. we must come to see that no individual can live alone: no nation can live alone. we must all live together; we must all be concerned about each other. which phrase best summarizes the speaker’s claim that americans must come together as equals?
