It is a challenging invitation to participate in Berkeley's Centenary Lectures dealing with the nature of the rule of law. My perspective is that of the judge. So when I venture to offer some thoughts about the rule of law, I focus on law as it is pronounced by judges. The matter I will explore is the age-old inquiry as to what it is that a judge is doing when he or she endeavors to a case, especially a close case presenting a choice between two plausible, indeed, respectable, contentions of law. In considering this topic already pondered by so many, the most I can expect is to illuminate some small aspect of the matter. It would be presumptuous to claim to be doing more. So, despite the breadth of the topic, my concern will be rather narrow-a modest effort to suggest some of the considerations that I believe judges have in mind when they decide issues of law, especially nonconstitutional issues. To confine my focus primarily to nonconstitutional issues is admittedly to withdraw from the great debates that have raged concerning the nature of the adjudication process as practiced by the Justices of the Supreme Court. I think my narrower focus is justified by several considerations. First, the body of decisional law that constrains all judges other than Supreme Court Justices is dominated in important respects by the authoritative pronouncements of the Court. For the Justices, their own rulings are precedents available for refinement, reconsideration, and, on occasion, rejection. For the rest of us, they are precedents to be followed. Second, adjudication of constitutional issues, especially by the Supreme Court, involves consideration of a range of values of constitutional dimension, far broader in scope than the concerns that bear on most of the nonconstitutional questions adjudicated in the federal courts of appeals, the federal district courts, and the state courts. Finally, the day-to-day activity of judges serving on these courts is largely devoted to nonconstitutional business; it is therefore worth considering what influences these decisions, even if such inquiry sheds
