In recent columns I've argued that a free society depends ultimately on people having a proper sense of just conduct. This means more than the words they recite or put on paper. Most crucial is how they act and expect others to act. For this reason it is futile to put undue emphasis on written constitutions as the key to liberty. The real constitution is within -- each of us. If the freedom philosophy is not inscribed in the actions of people, no constitution will help.
