      What I am describing here is a paradigm shift. It is caused by areaction to new information being introduced into an environment. When thishappens, the effect (depending upon the magnitude of the new information)can be tremulous and dramatic. In each of our lives, we have experiencedparadigm shifts that, for lack of more eloquent terminology, "rock ourworld." Whether it was a death in the family, a divorce, or a winninglottery ticket, the effect of the introduction of such new information hasa powerful, paradigm-shifting effect. Our previous vision of the futureevaporates before our eyes. In most cases, it takes some time for the dustto settle. When it does, a new vision of the future appears, and theprocess of the paradigm shift is complete.
