Alexander von Humboldt (1769-1859) was an intrepid explorer and the most famous scientist of his age. His restless life was packed with adventure and discovery, whether climbing the highest volcanoes in the world or racing through anthrax-infested Siberia. He came up with a radical vision of nature, that it was a complex and interconnected global force and did not exist for man's use alone. Ironically, his ideas have become so accepted and widespread that he has been nearly forgotten.

Ralph Waldo Emerson is one of the most important figures in the history of American thought, religion, and literature. The vitality of his writings and the unsettling power of his example continue to influence us more than a hundred years after his death. Now Robert D. Richardson Jr. brings to life an Emerson very different from the old stereotype of the passionless Sage of Concord.

The best-selling author of Truman and John Adams, David McCullough has written profiles of exceptional men and women past and present who have not only shaped the course of history or changed how we see the world but whose stories express much that is timeless about the human condition. Here are Alexander von Humboldt, whose epic explorations of South America surpassed the Lewis and Clark expedition; Harriet Beecher Stowe, "the little woman who made the big war”....

Over the course of his distinguished career, David McCullough has spoken before Congress, colleges and universities, historical societies, and other esteemed institutions. Now, at a time of self-reflection in America following a bitter election campaign that has left the country divided, McCullough has collected some of his most important speeches in a brief volume designed to identify important principles and characteristics that are particularly American.

The most thorough statement of one of Emerson's recurrent themes, the need for each individual to avoid conformity and false consistency, and follow his or her own instincts and ideas. It is the source of one of Emerson's most famous quotations, "A foolish consistency is the hobgoblin of little minds." This essay is a considered a watershed moment in which transcendentalism became a major cultural movement. An American classic.

On May 15, 2003, David McCullough presented "The Course of Human Events" as The 2003 Jefferson Lecture in the Humanities in Washington, DC. The Jefferson Lecture is a tribute to McCullough's lifetime investigation of history.

"I am hopelessly and forever a mountaineer," John Muir wrote. "Civilization and fever and all the morbidness that has been hooted at me has not dimmed my glacial eye, and I care to live only to entice people to look at Nature's loveliness. My own special self is nothing". In Donald Worster's magisterial biography, John Muir's "special self" is fully explored as is his extraordinary ability, then and now, to get others to see the sacred beauty of the natural world.

Writing was the central passion of Emerson's life. While his thoughts on the craft are well developed in "The Poet", "The American Scholar", Nature, "Goethe", and "Persian Poetry", less well known are the many pages in his private journals devoted to the relationship between writing and reading. Here, for the first time, is the Concord Sage's energetic, exuberant, and unconventional advice on the idea of writing, focused and distilled by the preeminent Emerson biographer at work today.

The compelling story of the effect of Charles Darwin's book On the Origin of Species on a diverse group of American writers, abolitionists, and social reformers, including Henry David Thoreau and Bronson Alcott, in 1860.

Thomas Jefferson was an avid book-collector, a voracious reader, and a gifted writer - a man who prided himself on his knowledge of classical and modern languages and whose marginal annotations include quotations from Euripides, Herodotus, and Milton. And yet there has never been a literary life of our most literary president.

When facing a moral dilemma, Isabel Dalhousie--Edinburgh philosopher, amateur detective, and title character of a series of novels by best-selling author Alexander McCall Smith - often refers to the great twentieth-century poet W. H. Auden. This is no accident: McCall Smith has long been fascinated by Auden. Indeed, the novelist, best known for his No. 1 Ladies Detective Agency series, calls the poet not only the greatest literary discovery of his life but also the best of guides on how to live.

Henry David Thoreau has long been an intellectual icon and folk hero. In this strikingly original profile, Michael Sims reveals how the bookish, quirky young man evolved into the patron saint of environmentalism and nonviolent activism. Working from 19th-century letters and diaries, Sims charts Henry’s course from his time at Harvard through the years he spent living in a cabin beside Walden Pond. Sims uncovers a previously hidden Thoreau - the rowdy boy reminiscent of Tom Sawyer, the sarcastic college iconoclast, the devoted son who kept imitating his beloved older brother’s choices in life.

C. S. Lewis is the 20th century's most widely read Christian writer and J. R. R. Tolkien its most beloved mythmaker. For three decades they and their closest associates formed a literary club known as the Inklings, which met weekly in Lewis' Oxford rooms and a nearby pub. They read aloud from works in progress, argued about anything that caught their fancy, and gave one another invaluable companionship, inspiration, and criticism.

A Life Observed tells the inspiring story of Lewis' spiritual journey from cynical atheist to joyous Christian. Drawing on Lewis' autobiographical works, books by those who knew him personally, and his apologetic and fictional writing, this spiritual biography brings the beloved author’s story to life while shedding light on his best-known works.
