William C. Spears is a US Navy Submarine Warfare Officer with over 25 years of service and author of Stoicism as a Warrior Philosophy. It is one of the best modern interpretations of Stoicism I have read.
As a husband, father, and military leader, Will has grown to use virtue — excellence of character grounded in reason — as a core standard for all actions within each role of life.
In this conversation, we discussed the history, principles, and practical insights from Stoicism in extreme environments and everyday life. We also cover teaching virtue, cosmopolitanism vs. military duty, moral clarity, eclecticism, attitude, and much more.
This was one of the best conversations I’ve had on philosophy. Will has a unique ability to make concepts actionable based on his understanding of philosophers throughout history.
If you enjoy Stoicism, I strongly recommend getting his book. Military or civilian, Will’s writing makes Stoic principles relevant to all roles in life: Stoicism as a Warrior Philosophy
Will just began writing on Substack. His first on James Stockdale, who we also discuss in this episode, is well worth your time. Get more from Will on Substack at: Officium: Stoicism and Military Service
You can also find him on LinkedIn.
