Lives of the Stoics, by Ryan Holiday and Stephen Hanselman
Lives of the Stoics is a collection of short biographies. Like other books about Stoicism written by the authors, Lives of the Stoics does not pretend to dive deeply into the philosophy of the Stoics nor be an historical treaty, but to provide inspiration for life through its insights and stories.
From Zeno to Marcus Aurelius, the authors give a good introduction to the lives and context of each stoic, distilling the essentials of their character, their historical background, their struggles with the powers that be, and other highlights of their lives. Courage, Justice, Temperance, and Wisdom. Self-rule is the greatest empire, character is fate.
