Courts sit to hear controversies between parties over facts and law. Rules of procedure are for the purpose of reducing the issues of fact and law in such controversies to a form as narrow and concrete as possible. Men who are able to present a clear statement of the evidence and who are learned in the principles of the law and their application to the facts as they are developed are in a position to assist the judge to a quick and thorough understanding of the exact question which he is to decide. The real enthusiasm of advocacy which is necessarily developed by the relation of attorney and client would doubtless have a tendency to mislead the court if exerted in behalf of one side only, but where both sides are represented, where the same earnestness in the proceeding of each side is present, it is the best method within human ken to reach a sound conclusion both as to the facts and as to the law. No one who has had experience on the Bench in reaching judicial conclusions and who has thereafter been obliged in an executive position to reach important, and it may be final, conclusions upon questions involving both fact and law, can fail to recognize and acknowledge the powerful influence for justice that honorable and learned members of the law exert in the causes which they present to a court. The counsel who argues the losing side of a case contributes quite as much to the assistance of the court as the successful advocate. The friction of counsel's argument against counsel's argument develops every phase of possible error in a conclusion and thereby enables a just, intelligent, acute and experienced court to see clearly what is the right which should be embodied in its judgment.
