Henry at Work invites listeners to rethink how we work today by exploring an aspect of Henry David Thoreau that has often been overlooked: Thoreau the worker. John Kaag and Jonathan van Belle overturn the popular misconception of Thoreau as a navel-gazing recluse who was scornful of work and other mundanities. In fact, Thoreau worked hard—surveying land, running his family's pencil-making business, writing, lecturing, and building his cabin at Walden Pond—and thought intensely about work in its many dimensions.

Hiking with Nietzsche is a tale of two philosophical journeys - one made by John Kaag as an introspective young man of 19, the other 17 years later and in quite different circumstances: as a husband and father. Both journeys are made in search of the wisdom at the core of Nietzsche's philosophy, but they deliver him to radically different interpretations and, more crucially, revelations about the human condition.

In American Philosophy, John Kaag - a disillusioned philosopher at sea in his marriage and career - stumbles upon a treasure trove of rare books on an old estate in the hinterlands of New Hampshire that once belonged to the Harvard philosopher William Ernest Hocking. The library includes notes from Whitman, inscriptions from Frost, and first editions of Hobbes, Descartes, and Kant. As he begins to catalog and preserve these priceless books, Kaag rediscovers the very tenets of American philosophy.

The Bloods were one of America’s first and most expansive pioneer families. They explored and laid claim to the frontiers―geographic, political, intellectual, and spiritual―that would become the very core of the United States. John Kaag’s American Bloods is the account of a remarkable American family, of its participation in the making of a nation, and of how its members embodied the elusive ideals enshrined in the Declaration of Independence.

Harry Haller is a sad and lonely figure, a reclusive intellectual for whom life holds no joy. He struggles to reconcile the wild primeval wolf and the rational man within himself without surrendering to the bourgeois values he despises. His life changes dramatically when he meets a woman who is his opposite, the carefree and elusive Hermine.
