To say that the future will be different from the present and past may be hopelessly self-evident. I must observe regretfully, however, that in politics it can be heresy. It can be denounced as radicalism or branded as subversion. There are people in every time and every land who want to stop history in its tracks. They fear the future, mistrust the present and invoke the security of a comfortable past which, in fact, never existed. It hardly seems necessary to point out in the United States, of all places, that change, although it involves risks, is the law of life.
