THE GREATNESS OF JUSTICE THOMAS: If you read nothing else this week, this month, this year, sit down in a quiet place and focus your mind on the words delivered April 20 at the University of Texas by Supreme Court Justice Clarence Thomas. Don’t skim it, don’t skip long paragraphs, read it carefully, slowly and fully focused. It may well be the most vital and energetic explanation of the American founding since Madison, Hamilton and Jay collaborated on The Federalist Papers.
