All through his early poems runs the thread of a fine morality, the perception of the highest obligations of religion and philanthropy, the subtle distinction of the purest Christianity, the defense of the weak and oppressed, the succor of the poor; in fine, the creed of a practical religion which required its adherent to go into the slums and out on the highways to carry out his convictions in acts. In the warfare he waged on slavery when the anti-slavery cause was very unpopular, and, in the case of Garrison and others, brought on its advocates continual danger and occasional violence, Lowell was unsparing in the denunciation of the national sin; but whether because the anti-abolition public which ruled Boston thought denunciation in form of verse had no practical value, or because the personal fascination the man always exercised on all around him was such as to disarm hostility, it happened that he was never made the object of aggression. "Men called him but a shiftless youth, In whom no good they saw; And yet, unwittingly, in truth, They made his careless word their law. "Men granted that his speech was wise, But, when a glance they caught Of his slim grace and woman's eyes, They laughed and called him good-for-naught." There was a gracious indolence in him, an imperturbable serenity, which made proclamation in advance of a truce to all forms of brute collision. No doubt if they had hunted him out for a victim of the political animosity which led to so many tragedies in the early days of our anti-slavery agitation, he would have stood up to the stake as gayly as one of the martyrs of old; but the man's nature was repugnant to discords, and shrank from combats ruder than those of the printing-press. All through his career, the religion of humanity is put forward with point and persistence, and the finest of distinctions in morality are maintained,--the so constantly ignored vital difference between the deed and its motive, as in "Sir Launfal:"-- "The Holy Supper is kept, indeed, In whatso we share with another's need; Not what we give, but what we share,-- For the gift without the giver is bare; Who gives himself with his alms feeds three,-- Himself, his hungering neighbor, and Me;"
