Literary critics have not shared his high estimate of the composition. In general they have esteemed it a rather mediocre piece. But its rhythm is accurate, and its rhyme is good, and its plaintive sentiment accorded with the melancholy of Lincoln and of his social environment. It is not the only poem of no great literary merit which became popular in that period; and it would have been forgotten with the rest but for the association of its lines with the name of Abraham Lincoln. He gave to it and its author their chief claim to immortality. During his Presidency, Lincoln said: There is a poem which has been a great favorite with me for years, which was first shown me when a young man, by a friend, and which I afterwards saw and cut from a newspaper and learned by heart. I would give a good deal to know who wrote it, but I have never been able to ascertain. The author of the poem, "Oh, why should the spirit of mortal be proud?" was William Knox, who was born at Firth, in the parish of Lilliesleaf, in the county of Roxburghshire, in Scotland, on the 17th of August, 1789, and who died at the age of thirty-six. From his early childhood he wrote verses, and he attained sufficient prominence to win the attention of Walter Scott, who encouraged him and loaned him money. What he might have done had he lived, we do not know; but this is the only poem of his that has any claim to distinction, and that not for its own outstanding merit, but for its association with Abraham Lincoln. Knox's earliest volume, "The Harp of Zion," was published in 1825, and does not contain this poem. What appears to have been an inclusive volume of the poems of Knox was published in London and Edinburgh in 1847, and bore the title "The Lonely Hearth, The Songs of Israel, Harp of Zion, and Other Poems." This includes the poem which bears the title "Mortality." It is interesting to recall that it has sometimes been printed with the title "Immortality." To that title, however, it can bear no claim. It will be of interest to compare the poem in its entirety with the stanzas which Lincoln quoted on the occasion of his oration in memory of the deceased President, General Zachary Taylor. MORTALITY BY WILLIAM KNOX Oh, why should the spirit of mortal be proud? Like a swift flying meteor, a fast flying cloud, A flash of the lightning, a break of the wave, Man passeth from life to his rest in the grave. The leaves of the oak and the willow shall fade, Be scattered around and together be laid; And the young and the old, and the low and the high, Shall moulder to dust and together shall lie. The infant a mother attended and loved; The mother that infant's affection who proved; The husband that mother and infant who blessed, Each, all, are away to their dwellings of rest.
