Ryan Holiday, bestselling author and Stoicism expert, joins General James Mattis, former Secretary of Defense and four-star Marine general, for their first public meeting on PBS's Firing Line. The conversation explores how ancient Stoic philosophy applies to modern leadership and American democracy.

General Mattis, known as the 'warrior monk' for his extensive library and philosophical approach to military leadership, has carried Meditations by Marcus Aurelius throughout his 40-year career. Holiday, author of Courage is Calling, views Mattis as a modern embodiment of the warrior-philosopher archetype.

Their discussion examines how Stoic virtues of courage, discipline, justice, and wisdom guided historical figures like George Washington and Abraham Lincoln, and why these ancient principles remain essential for contemporary civic engagement and democratic leadership.

Philosophy as Practical Tool for Crisis Leadership

General Mattis explains that military leaders 'careen from one crisis to another' where affected people are not in control, requiring leaders to 'fall back on something' - in his case, Stoic values that keep him calm enough for purposeful action.

Holiday emphasizes studying philosophy to avoid learning 'by trial and error,' which is 'both arrogant and reckless,' since the cost is 'largely paid by people other than you.'

The origin story of Stoicism involves Zeno asking the Oracle at Apollo's temple for the secret to good life, learning it means 'having conversations with the dead' through reading and studying ancient wisdom.

Washington's Stoic Self-Mastery and Revolutionary Leadership

Washington had a 'volcanic temper' but learned Stoic self-control, with one sculptor noting 'fiery passions' beneath the surface - his 'first victory was over himself' before governing others.

Despite facing 'a hundred quantifiable reasons why we failed in our Revolutionary War,' Washington kept his army alive against the world's finest military force through consistent leadership patterns.

Washington's method was always the same: 'He listens with a willingness to be persuaded, quiets himself down, tones down his temper, and learns' - even hearing 'what's not being said.'

Thomas Paine wrote that adversity 'unlocks a cabinet of fortitude' in Washington, embodying the Stoic principle of getting stronger through obstacles rather than withering under pressure.

Lincoln's Unique Embodiment of All Four Stoic Virtues

Lincoln is 'perhaps the only president to simultaneously embody all four Stoic virtues' - courage, discipline, justice, and wisdom - according to Holiday.

Unlike other towering historical figures like Napoleon or Caesar, Lincoln 'uses his ambition, his power, to bind a nation together, to heal, to put it back together.'

Lincoln wrote that 'every man has their peculiar ambition' but chose to become great 'by freeing slaves' rather than 'making slaves of men.'

Lincoln combined being 'an incredibly crafty and pragmatic politician' with having 'flat-ass rules, some things he would not do' - lines more important than political success.

Founding Fathers and Ancient Philosophical Foundations

First Principles by Tom Ricks shows how founders drew from the Enlightenment, 'which is all based on ancient Greek and Roman philosophers,' creating documents with 'skepticism about human nature, yet belief in the people.'

Mattis emphasizes falling back on First Principles during crises: 'Declaration of Independence, the Constitution, the Bill of Rights' - documents grounded in ancient wisdom.

The founders faced their own dark times, with Mattis noting 'the founding fathers were mostly still alive when we nearly made Aaron Burr our president' - proving current challenges aren't unprecedented.

Civic Duty and Democratic Participation in Modern America

Mattis declares 'democracy is not a spectator sport' and 'we are all custodians of our democracy' with the obligation to be 'protectors of our Constitution.'

The concept of 'usufruct' from Thomas Jefferson means citizens hold the nation like inheriting a farm - 'obligated to turn it over to your son or daughter in as good condition or better than you got it.'

Holiday distinguishes Stoics from Epicureans: Epicureans 'got involved in politics only if they had to' while 'Stoics got involved unless something prevented them.'

With '50% of adults don't vote,' Holiday asks who philosophically-inclined people are 'ceding the fields to' if they don't participate in the democratic process.
