Another of the ideas that master Whitman and rule him is the idea of identity,--that you are you and I am I, and that we are henceforth secure whatever comes or goes. He revels in this idea; it is fruitful with him; it begets in him the ego-enthusiasm, and is at the bottom of his unshakable faith in immortality. It leavens all his work. It cannot be too often said that the book is not merely a collection of pretty poems, themes elaborated and followed out at long removes from the personality of the poet, but a series of _sorties_ into the world of materials, the American world, piercing through the ostensible shows of things to the interior meanings, and illustrating in a free and large way the genesis and growth of a man, his free use of the world about him, appropriating it to himself, seeking his spiritual identity through its various objects and experiences, and giving in many direct and indirect ways the meaning and satisfaction of life. There is much in it that is not poetical in the popular sense, much that is neutral and negative, and yet is an integral part of the whole, as is the case in the world we inhabit. If it offends, it is in a wholesome way, like objects in the open air. III Whitman rarely celebrates exceptional characters. He loves the common humanity, and finds his ideals among the masses. It is not difficult to reconcile his attraction toward the average man, towards workingmen and "powerful, uneducated persons," with the ideal of a high excellence, because he finally rests only upon the most elevated and heroic personal qualities,--elevated but well grounded in the common and universal. The types upon which he dwells the most fondly are of the common people. "I knew a man, He was a common farmer--he was the father of five sons, And in them were the fathers of sons--and in them were the fathers of sons.
