 In 1863 Julia Ward Howe wrote the popular hymn the Battle Hymn of the Republic to the tune of "John Brown's body", which included a line "As He died to make men holy, let us die to make men free", analogizing Brown's sacrifice to that of Jesus Christ.Writers continue to vigorously debate Brown's personality, sanity, motivations, morality, and relation to abolitionism.In his posthumous "The Impending Crisis, 1848–1861" (1976), David Potter argued that the emotional effect of Brown's raid exceeded the philosophical effect of the Lincoln–Douglas debates, and reaffirmed a deep division between North and South.
