Humanism is an expansive tradition of thought that places shared humanity, cultural vibrancy, and moral responsibility at the center of our lives. For centuries, this worldview has inspired people to make their choices by principles of freethinking, intellectual inquiry, fellow feeling, and optimism. In this sweeping new history, Sarah Bakewell, herself a lifelong humanist, illuminates the very personal, individual, and, well, human matter of humanism and takes listeners on a grand intellectual adventure.

There is a cause, or a reason, behind everything that happens. This is the fundamental view behind the classical proposition the Principle of Sufficient Reason, which, in 1813, Schopenhauer chose as his subject for further examination in his doctoral dissertation On the Fourfold Root of the Principle of Sufficient Reason....

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were - and still are. The Structure of Scientific Revolutions is that kind of book.

The modern world can be a complicated, frenzied, and noisy place, filled with too many options, products, ideas and opinions. That explains why what many of us long for is simplicity: a life that can be more pared down, peaceful, and focused on the essentials. But finding simplicity is not always easy; it isn’t just a case of emptying out our closets or trimming back commitments in our diaries. True simplicity requires that we understand the roots of our distractions – and develop a canny respect for the stubborn reasons why things can grow complex and overwhelming.

Conjectures and Refutations is one of Karl Popper’s most wide-ranging and popular works, notable not only for its acute insights into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge but our aims and our standards grow through an unending process of trial and error.

In a field known for startling ideas, the Many-Worlds Interpretation (MWI) of quantum mechanics may take the prize. It holds that parallel to our own world are a large number of other universes, almost identical to ours but with small variations. Copies of each of us inhabit a myriad of these worlds. But they are not us exactly; they share our past history, but they are different people who have unique futures. Although these realms are invisible and can’t communicate with each other, prominent physicists are convinced they must exist.

The Enchiridion is the famous manual of ethical advice given in the second century by the Stoic philosopher Epictetus. Born to a Greek slave, Epictetus grew up in the environment of the Roman Empire and, having been released from bonds of slavery, became a stoic in the tradition of its originators, Zeno (third Century BCE) and Seneca (first century CE).

Eric Weiner combines his twin passions for philosophy and travel in a globe-trotting pil­grimage that uncovers surprising life lessons from great thinkers around the world, from Rousseau to Nietzsche, Confucius to Simone Weil. Traveling by train (the most thoughtful mode of transport), he journeys thousands of miles, making stops in Athens, Delhi, Wyoming, Coney Island, Frankfurt, and points in between to recon­nect with philosophy’s original purpose: teaching us how to lead wiser, more meaningful lives.

As a botanist and professor of plant ecology, Robin Wall Kimmerer has spent a career learning how to ask questions of nature using the tools of science. As a Potawatomi woman, she learned from elders, family, and history that the Potawatomi, as well as a majority of other cultures indigenous to this land, consider plants and animals to be our oldest teachers.

You might think laziness, lack of willpower, and/or low motivation are to blame for the fact that you aren't achieving your goals. But fascinating research in the field of psychoneuroimmunology has revealed another, far more likely possibility. One with the potential to transform your life in a dramatic way.

The 13 chapters of The Art of War, each devoted to one aspect of warfare, were compiled by the high-ranking Chinese military general, strategist, and philosopher Sun-Tzu. In spite of its battlefield specificity, The Art of War has found new life in the modern age, with leaders in fields as wide and far-reaching as world politics, human psychology, and corporate strategy finding valuable insight in its timeworn words.

My Big TOE: Awakening, written by a nuclear physicist in the language of contemporary culture, unifies science and philosophy, physics and metaphysics, mind and matter, purpose and meaning, the normal and the paranormal. The entirety of human experience (mind, body, and spirit) including both our objective and subjective worlds is brought together under one seamless scientific understanding.

The ancient Toltecs believed that life, as we perceive it, is a dream. We each live in our own personal dream, and these come together to form the dream of the planet, or the world in which we live. Problems arise when our perception of the dream becomes clouded with negativity, drama, and judgment (of ourselves and others), because it's in these moments of suffering that we have forgotten that we are the architects of our own reality and we have the power to change our dream if we choose.

Why have history's greatest minds - from George Washington to Frederick the Great to Ralph Waldo Emerson along with today's top performers, from Super Bowl-winning football coaches to CEOs and celebrities - embraced the wisdom of the ancient Stoics? Because they realize that the most valuable wisdom is timeless and that philosophy is for living a better life, not a classroom exercise. The Daily Stoic offers a daily devotional of Stoic insights and exercises, featuring all-new translations.
