From Judge Richard Posner:

I see absolutely no value to a judge of spending decades, years, months, weeks, day, hours, minutes, or seconds studying the Constitution, the history of its enactment, its amendments, and its implementation (across the centuries—well, just a little more than two centuries, and of course less for many of the amendments). Eighteenth-century guys, however smart, could not foresee the culture, technology, etc., of the 21^stcentury. Which means that the original Constitution, the Bill of Rights, and the post–Civil War amendments (including the 14^th), do not speak to today.
