The Discourses — Why Machiavelli Preferred Republics
"The people are wiser and more constant than a prince… a people bound by laws will surpass a prince." — Machiavelli, Discourses on Livy
Military and Political Context
Most people have read only The Prince, while the book Machiavelli invested far more in — and wrote at far greater length — is another one entirely.
The Discourses on the First Ten Books of Titus Livy runs roughly three times the length of The Prince, took years to write, and is his actual work of political science. Its central conclusion is nearly the opposite of The Prince.
1. The Two Books in Opposition
| The Prince | Discourses | |
|---|---|---|
| Subject | How an individual seizes and holds power | How a state sustains liberty and strength over time |
| Ideal form | A strong prince | A republic |
| Source of durability | The ruler's skill and cunning | Institutions, laws, and civic participation |
| Nature of the work | A short piece dedicated to a ruler | A long treatise from years of study |
The Discourses argues explicitly that republics are more durable, better at self-correction, and better at expansion than principalities.
2. His Reasons
Machiavelli's argument is functional rather than moral — which matters.
He held republics superior not because liberty is noble but because they operate more robustly in practice:
- Self-correction: nobody can correct a prince's errors, while a republic's institutions permit replacement and revision
- Independence from individual quality: a principality's fate rests on whether one man is capable, which cannot be guaranteed
- Participants have a stake: citizens fighting for their own state are far more reliable than mercenaries
- Conflict can be constructive: he even argues the open conflict between Roman plebeians and patricians strengthened the state, because it produced law
The second is the core: institutions are valuable because they make outcomes independent of any single person's qualities.

3. This Is Exactly the Structure-Versus-Skill Argument in Investing
Machiavelli's two books map onto two paths in investing.
The Prince style: relying on individual judgment, timing, and discipline. It can succeed, but success depends on that person sustaining their form — exactly as a principality depends on the prince being capable.
Discourses style: relying on institutions and rules. Automatic contributions, automatic rebalancing, a written investment policy, a target-date fund. It requires nobody to perform well, only that the system keeps running.
And Machiavelli, on longer reflection, chose the second.
4. Why Institutions Win Over Time
His four arguments for republics each translate directly:
| Republican advantage | Investing counterpart |
|---|---|
| Self-correction | Rebalancing corrects allocation drift without judgment |
| Independence from individual quality | The plan runs while you are unwell, distracted, or old |
| Participants have a stake | Rules you wrote yourself are easier to follow than outside advice |
| Constructive conflict | The clash between written rules and present emotion IS the protection |
The second matters enormously for retirees and is rarely discussed: your plan must keep working when you are eighty-five, cognitively slower, or in poor health.
A plan depending on you continuing to make sound judgments is least reliable exactly when you most need it to be reliable.
5. It Is Also a Question of Succession
Machiavelli identifies a structural weakness in principalities: succession. An outstanding prince is usually followed by a mediocre one, and the state's fortunes turn with it.
The investing counterpart is inheritance and spouses: if your portfolio is complex enough that only you can manage it, then after your death or incapacity it passes to someone who does not understand it.
This is a rarely mentioned value of simplicity: a portfolio of three or four index funds can be held by a spouse or child without you. One built from twenty individual stocks, option hedges, and active strategies cannot.
Actionable Trading Rules
- Build a plan independent of your personal state: ask whether it still functions if you do not look at it for six months.
- Design for comprehensibility by a successor: your portfolio should be inheritable by a family member who knows nothing about investing.
- Treat rule-versus-emotion conflict as protection, not obstruction: pre-written rules are useful precisely because they conflict with what you currently want.
Relevance to a Retirement Portfolio
This chapter is the genuine endpoint of the Wave 4 military series, because it gives the series' central conclusion its oldest formulation.
Nine military classics spanning twenty-five centuries point in one direction: structure beats individual quality. Sun Tzu's making yourself unconquerable first, Sima Rangju executing the king's favourite, Clausewitz on defence being stronger, Kahneman and Thaler on environmental design — all are one claim stated differently.
Machiavelli's version in the Discourses may be the most direct: a state depending on a wise prince decays as princes change; a state depending on good institutions endures for centuries.
Your retirement portfolio faces the same choice. It can depend on you sustaining judgment, discipline, and attention — or on a structure that runs while you are not participating.
Machiavelli studied four hundred years of Roman history and chose the second. For a plan that must survive thirty years of retirement, the choice is equally clear.
