The rapid changes in our social and industrial life which have attended this rapid growth have made it necessary that, in applying to concrete cases the great rule of right laid down in our Constitution, there should be a full understanding and appreciation of the new conditions to which the rules are to be applied. What would have been an infringement upon liberty half a century ago may be the necessary safeguard of liberty to-day.

Every judicial decision involves two terms—one, as interpretation of the law; the other, the understanding of the facts to which it is to be applied. The great mass of our judicial officers are, I believe, alive to those changes of conditions which so materially affect the performance of their judicial duties. Our judicial system is sound and effective at core, and it remains, and must ever be maintained, as the safeguard of those principles of liberty and justice which stand at the foundation of American institutions; for, as Burke finely said, when liberty and justice are separated, neither is safe.
