Academia and practical law

Judge Richard Posner of the 7th Circuit was quoted as saying:
“And on another note about academia and practical law, 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 21st century. Which means that the original Constitution, the Bill of Rights, and the post–Civil War amendments (including the 14th), do not speak to today.”
