“In The Atlantic’s very first issue, in 1857, the magazine’s founders — an illustrious group that included Ralph Waldo Emerson, Oliver Wendell Holmes, Henry Wadsworth Longfellow, and James Russell Lowell — declared that they would dedicate their new publication to monitoring the development, and advancing the cause, of what they called ‘the American idea.’ And for the last century and a half, the magazine has been preoccupied with the fundamental subjects of the American experience: war and peace, science and religion, the conundrum of race, the role of women, the plight of the cities, the struggle to preserve the environment, the strengths and failings of our politics, and especially, America’s proper place in the world.” To commemorate the magazine’s 150th anniversary, The Atlantic Monthly publishes The American Idea, an anthology of articles which includes republished writings by TR, W.E.B. DuBois, Albert Einstein, John Muir, Helen Keller, and Vannevar Bush. (Alas, only ten of the included articles are online.)
