This book is simple and effective, with clear explanations and methodical organization. Irvine argues that, unlike the ancient Greeks and Romans, modern people tend to lack a philosophy for living, and that people can benefit from incorporating philosophical principles into their daily life. He makes the case for Stoicism in particular as a philosophy with special utility in helping people manage negative emotions and attain a greater sense of tranquility.

Throughout the book he introduces the major figures in Stoic history, their teachings, and advises how to apply them to modern life. Dealing with insults, aging, insults, and grief are all topics covered in the book. While Stoicism today is somewhat obscure and misunderstood, many readers will see familiar parallels in Buddhism (which also understands that desire and attachments are a source of frustration and misery) and the literature about mindfulness.

While I discovered and adopted Stoicism on my own two decades ago (I'm what the author terms a "congenital Stoic"), I appreciated the history lesson and the systematic presentation of the philosophy's tenets and their application. While an interest in history is a plus, I'd recommend this book wholeheartedly to anyone seeking more equanimity in their daily life, especially if they're skeptical of religion.
