The Four Cardinal Virtues
This week you are going to learn about the Four Cardinal Virtues: wisdom, courage, justice, and temperance. "Cardinal" comes from the Latin cardo, meaning hinge. These four are the hinges on which a good life swings. The Stoics inherited them from Plato and Socrates, then sharpened them into something practical: not ideals to admire from a distance, but habits of mind and action you can exercise every single day. By Saturday, you will not just know what they are; you will have a feel for how they work together as one way of living.
Passage
Bravery is a scorner of things which inspire fear; it looks down upon, challenges, and crushes the powers of terror and all that would drive our freedom under the yoke. But do “liberal studies” strengthen this virtue? Loyalty is the holiest good in the human heart; it is forced into betrayal by no constraint, and it is bribed by no rewards. Loyalty cries: “Burn me, slay me, kill me! I shall not betray my trust; and the more urgently torture shall seek to find my secret, the deeper in my heart will I bury it!” Can the “liberal arts” produce such a spirit within us? Temperance controls our desires; some it hates and routs, others it regulates and restores to a healthy measure, nor does it ever approach our desires for their own sake. Temperance knows that the best measure of the appetites is not what you want to take, but what you ought to take.
— Seneca, Letters 88.29
Reflection
Seneca focuses today on two of the four virtues: courage (which he calls a scorner of fear) and temperance (which he calls the regulator of desire). Notice how he defines them. Courage is not the absence of fear; it is the capacity to look fear in the face and refuse to let it make your decisions. Temperance is not deprivation; it is knowing the difference between what you want to take and what you ought to take. Both definitions point at the same underlying skill: your reason governs your impulses, not the other way around. This is what the Stoics meant when they called virtue a kind of knowledge. Each virtue is a trained, reliable way of perceiving and responding to the world.
Go deeper
Where in your life right now is fear or appetite quietly making decisions for you that you have not consciously handed over to them?
Practice
Name the Driver
Sit quietly for five minutes. Bring to mind one decision you are currently avoiding or one habit you keep repeating despite knowing better. Ask yourself plainly: what is driving this, fear or appetite? Name it specifically (fear of embarrassment, appetite for comfort, craving for distraction). You do not need to fix it today; just identify it accurately. Seneca would say that naming the thing is the first act of courage or temperance, depending on which you need.
