Just here emerges another phase of his amenability to law. It operates as an impulse to plead. It drives him to the rostrum, and makes of him one of the foremost masters of public address our civic life and history have produced. As Lincoln voices this address he is speaking not merely to himself, nor for himself, nor to ease and unburden his mind, nor yet to open and indicate his view. As he spoke those words his eye was fixed upon a mighty multitude of his fellowmen. As he unfolded his thought before their attentive, waiting minds, it was as though a banner were being unfurled to symbolize and signify to a Nation's multitudes the sovereign duty of all true patriots. In that transaction he became undeniably prophet and lawgiver to the Nation. The obligations that supremely bind his life he urges and attests as binding with equal and evident urgency upon the millions upon millions of the members in the same free and solemn political league. When his speech is done, he would have all who hear conjoined indefeasibly with him in loyalty to his law. Every sentence of the address bears evidence of this design. He is aiming to bring the Nation's conscience and will to embody and obey the identical mandates that govern him. But his appeal is vestured in ideal deference. He deals with law. But he does not command. Throughout his solemn exposition there is no note or hint of dictatorship of any sort. Not a breath in any accent suggests any undertaking to coerce. He simply strives, as a man with his friend, to persuade. And yet as he sets forth his speech, within the comely apparel of its courteous words gleams the regal form of duty, imperial offspring of inflexible law. Those words were no empty phrasings of indifferent platitudes, disposed and pronounced to dignify a passing pageant in the formal rounds of our civic life. They trembled with anxiety. He spoke of nothing less than the Nation's life and death, the Nation's duty, and the Nation's doom. The honor of the Republic was being sternly tried, to see if it was sound or rotten in its very heart. Lincoln was dealing with things that all men owned to be above all price. He was striving, as for life, to achieve agreement as to duties that should transcend all possible denial. He was trying to fasten upon every American conscience constraints that no American conscience could possibly escape.
