Another point had an early settlement, clearing the ground greatly. I saw, from the time my enterprise and questionings positively shaped themselves (how best can I express my own distinctive era and surroundings, America, Democracy?) that the trunk and centre whence the answer was to radiate, and to which all should return from straying however far a distance, must be an identical body and soul, a personality—which personality, after many considerations and ponderings I deliberately settled should be myself—indeed could not be any other. I also felt strongly (whether I have shown it or not) that to the true and full estimate of the Present both the Past and the Future are main considerations.
These, however, and much more might have gone on and come to naught (almost positively would have come to naught,) if a sudden, vast, terrible, direct and indirect stimulus for new and national declamatory expression had not been given to me. It is certain, I say, that, although I had made a start before, only from the occurrence of the Secession War, and what it show’d me as by flashes of lightning, with the emotional depths it sounded and arous’d (of course, I don’t mean in my own heart only, I saw it just as plainly in others, in millions)—that only from the strong flare and provocation of that war’s sights and scenes the final reasons-for-being of an autochthonic and passionate song definitely came forth.
I went down to the war fields in Virginia (end of 1862), lived thenceforward in camp—saw great battles and the days and nights afterward—partook of all the fluctuations, gloom, despair, hopes again arous’d, courage evoked—death readily risk’d— the cause , too—along and filling those agonistic and lurid following years, 1863–’64–’65—the real parturition years (more than 1776–’83) of this henceforth homogeneous Union. Without those three or four years and the experiences they gave, Leaves of Grass would not now be existing.
