All of us are faced countless times with the challenge of persuading others, whether we're trying to win a trivial argument with a friend or convince our coworkers about an important decision. Instead of relying on untrained instinct - and often failing as a result - we'd win more arguments if we learned the timeless art of verbal persuasion, or rhetoric.

In his essay On Anger, the Roman Stoic thinker Seneca argues that anger is the most destructive passion. This splendid new translation of essential selections from On Anger, presented with an enlightening introduction, offers listeners a timeless guide to avoiding and managing anger. Drawing on his great arsenal of rhetoric, including historical examples, anecdotes, quips, and soaring flights of eloquence, Seneca builds his case against anger with mounting intensity.

"It takes an entire lifetime to learn how to die", wrote the Roman Stoic philosopher Seneca (c. 4 BC-65 AD). He counseled readers to "study death always", and took his own advice, returning to the subject again and again in all his writings, yet he never treated it in a complete work. How to Die gathers in one volume, for the first time, Seneca's remarkable meditations on death and dying. Edited and translated by James S. Romm, How to Die reveals a provocative thinker who speaks with a startling frankness about the need to accept death or even, under certain conditions, to seek it out.

Born a slave, the Roman Stoic philosopher Epictetus (c. 55-135 AD) taught that mental freedom is supreme, since it can liberate one anywhere, even in a prison. In How to Be Free, A. A. Long - one of the world's leading authorities on Stoicism and a pioneer in its remarkable contemporary revival - provides a superb new edition of Epictetus's celebrated guide to the Stoic philosophy of life (the Encheiridion) along with a selection of related reflections in his Discourses.

The ancient biographer and essayist Plutarch thought deeply about the leadership qualities of the eminent Greeks and Romans he profiled in his famous - and massive - Lives, including politicians and generals such as Pericles, Alexander the Great, Julius Caesar, and Mark Antony. Luckily for us, Plutarch distilled what he learned about wise leadership in a handful of essays, which are filled with essential lessons for experienced and aspiring leaders in any field today.
