With John Brown, as with every other man fit to die for a cause, the hour of his physical weakness was the hour of his moral strength--the hour of his defeat was the hour of his triumph--the moment of his capture was the crowning victory of his life. With the Alleghany mountains for his pulpit, the country for his church and the whole civilized world for his audience, he was a thousand times more effective as a preacher than as a warrior, and the consciousness of this fact was the secret of his amazing complacency. Mighty with the sword of steel, he was mightier with the sword of the truth, and with this sword he literally swept the horizon. He was more than a match for all the Wises, Masons, Vallandinghams and Washingtons, who could rise against him. They could kill him, but they could not answer him. In studying the character and works of a great man, it is always desirable to learn in what he is distinguished from others, and what have been the causes of this difference. Such men as he whom we are now considering, come on to the theater of life only at long intervals. It is not always easy to explain the exact and logical causes that produce them, or the subtle influences which sustain them, at the immense heights where we sometimes find them; but we know that the hour and the man are seldom far apart, and that here, as elsewhere, the demand may in some mysterious way, regulate the supply. A great iniquity, hoary with age, proud and defiant, tainting the whole moral atmosphere of the country, subjecting both church and state to its control, demanded the startling shock which John Brown seemed especially inspired to give it.
