Stoic virtues, wisdom, and leading yourself when leaders fail

Executive overview

Most people apply moral standards outward — judging others' choices and behaviour. Stoicism inverts this: hold yourself to a strict standard, and leave others to their own path. The four Stoic virtues — courage, temperance, justice, and wisdom — are not innate traits but habits built through repeated action.

Wisdom isn't passively accumulated with age. It requires deliberate practice and the right models to measure yourself against.

Be strict with yourself, tolerant with others — and choose your models carefully.

The four Stoic virtues

• Courage, temperance (self-mastery), justice, and wisdom are the four core virtues
• Zeno called them distinct yet inseparable — each informs and shapes the others
• Courage without justice is directionless; wisdom tells us what is just
• Decency toward others falls under justice; self-restraint falls under temperance
• Every situation is an opportunity to practise some or all of the virtues

Tolerant with others, strict with yourself

• Stoicism is a personal philosophy — not a tool for policing others
• Others' lifestyle choices are outside your control; your reactions are not
• The Stoic position on others' behaviour: libertarian — "you do you"
• Justice is where intervention becomes appropriate; basic lifestyle is not your business
• America's founders, heavily influenced by the Stoics, built personal liberty into law — then expected personal virtue to fill the gaps

The need for historical models

• In the absence of trustworthy leaders, look backwards to historical figures
• Seneca: "Without a ruler, you can't make crooked straight" — you need a model to measure against
• Washington modelled himself on Cato and Cincinnatus; resigning power was a deliberate Stoic act
• General Mattis is cited as a modern example: carried Marcus Aurelius for 40 years of deployments, resigned on principle, never leaked or disparaged in public
• The risk today: history is taught by tearing down figures without replacing them with new models

Wisdom takes work

• Aristotle held that all virtues are verbs — actions and habits, not possessions
• Wisdom is a byproduct of deliberate choices, not of intelligence or age alone
• Age helps because it provides more experiences and, crucially, longer perspective
• Perspective is the essential ingredient — a 20-year span vs. a 60-year span changes what you can see
• Biases and bad habits can work against the natural accumulation of wisdom regardless of age
