Great men are more distinguished by range and extent, than by originality. If we require the originality which consists in weaving, like a spider, their web from their own bowels; in finding clay, and making bricks, and building the house; no great men are original. Nor does valuable originality consist in unlikeness to other men. The hero is in the press of knights, and the thick of events; and, seeing what men want, and sharing their desire, he adds the needful length of sight and of arm, to come at the desired point. The greatest genius is the most indebted man. A poet is no rattlebrain, saying what comes uppermost, and, because he says every thing, saying, at last, something good; but a heart in unison with his time and country. There is nothing whimsical and fantastic in his production, but sweet and sad earnest, freighted with the weightiest convictions, and pointed with the most determined aim which any man or class knows of in his times.
Ralph Waldo Emerson, Representative Men
