Emerson tried to make men feel that the beauty of the universe is the property of every individual, but that the many divest themselves of their heritage. When he undertook to tell Americans how to secure a warranty deed to the beauties of nature, he specially emphasized the moral element in the process. The student who fails to perceive that Emerson is one of the great moral teachers has studied him to little purpose. To him all the processes of nature "hint or thunder to man the laws of right and wrong, and echo the Ten Commandments." In _Nature_, he says:-- "All things with which we deal, preach to us. What is a farm but a mute gospel? The chaff and the wheat, weeds and plants, blight, rain, insects, sun,--it is a sacred emblem from the first furrow of spring to the last stack which the snow of winter overtakes in the fields." In _Nature_, Emerson sets forth his idealistic philosophy. "Idealism sees the world in God" is with him an axiom. This philosophy seems to him to free human beings from the tyranny of materialism, to enable them to use matter as a mere symbol in the solution of the soul's problems, and to make the world conformable to thought. His famous sentence in this connection is, "The sensual man conforms thoughts to things; the poet conforms things to his thoughts." In _The American Scholar_, an address delivered at Cambridge in 1837, Emerson announced what Oliver Wendell Holmes calls "our intellectual Declaration of Independence." Tocqueville, a gifted Frenchman who visited America in 1831, wrote: "I know no country in which there is so little independence of opinion and freedom of discussion as in America.... If great writers have not existed in America, the reason is very simply given in the fact that there can be no literary genius without freedom of opinion, and freedom of opinion does not exist in America." Harriet Martineau, an English woman, who came to America in 1830, thought that the subservience to opinion in and around Boston amounted to a sort of mania. We have already seen how Cooper in his early days deferred to English taste (p. 127), and how Andrew Jackson in his rough way proved something of a corrective (p. 148). Emerson proceeded to deal such subserviency a staggering blow. He denounced this "timid, imitative, tame spirit," emphasized the new importance given to the single person, and asked, "Is it not the chief disgrace in the world not to be a unit;--not to be reckoned one character;--not to yield that peculiar fruit which each man was created to bear; but to be reckoned in the gross, in the hundred, or the thousand, of the party, the section, to which we belong, and our opinion predicted geographically, as the North, or the South?" Then followed his famous declaration to Americans, "We will walk on our own feet; we will work with our own hands; we will speak our own minds."
