Why has the present renaissance of the poetry-lover not brought with it a renaissance of the American poet? Almost every reason but the true one has been given. The true reason is that our poets are tired. They became exhausted a couple of generations ago; and we have kept them in this condition ever since. In the previous chapter we saw how city life began abruptly to be speeded up in the seventies. At that time the poet--like almost every one else in the city--was unable to readjust his body at once to the new pace. He was like a six-day bicycle racer who should be lapped in a sudden and continued sprint. That sprint is still going on. Never again has the American poet felt the abounding energy with which he began. And never has he overtaken the leaders. The reason why the poet is tired is that he lives in the over-paced city. The reason why he lives in the city is that he is chained to it by the nature of his hack-work. And the reason for the hack-work is that the poet is the only one of all the artists whose art almost never offers him a living. He alone is forced to earn in other ways the luxury of performing his appointed task in the world. For, as Goethe once observed, "people are so used to regarding poetic talent as a free gift of the gods that they think the poet should be as free-handed with the public as the gods have been with him." The poet is tired. Great art, however, is not the product of exhaustion, but of exuberance. It will have none of the skimmed milk of mere existence. Nothing less than the thick, pure cream of abounding vitality will do. The exhausted artist has but three courses open to him: either to stimulate himself into a counterfeit, and suicidally brief, exuberance; or to relapse into mediocrity; or to gain a healthy fullness of life. In the previous chapter it was shown why poetry demands more imperatively than any other art, that the appreciator shall bring to it a margin of vitality. For a like reason poetry makes this same inordinate demand upon its maker. It insists that he shall keep himself even more keenly alive than the maker of music or sculpture, painting or architecture. This is the reason why, in the present era of overstrain, the poet's art has been so swift to succumb and so slow to recuperate.
