Something very strange has happened in the United States very recently. Traditional attitudes and values that have prevailed and come down from generation to generation in all but unbroken succession since the founding of the republic have suddenly been overturned or are in the process of being overturned. Traditional American ways of looking at things—including the traditional way of looking at our own past—have suddenly been reversed. A startling discontinuity, as stark as a geologic fault, has occurred in our cultural history since 1964.
It is a temptation, and one constantly yielded to by social commentators, to look upon these things (like the geologic fault) as having simply happened—as having occurred without human volition or control. The environment has changed, it is said; no wonder people and their attitudes change. The process is made to appear as inexorable as changes in the phase of the moon.
