What are the cardinal virtues?
The short answer
The cardinal virtues are four foundational strengths of character on which a good moral life turns: prudence, justice, fortitude, and temperance. They are called "cardinal" from the Latin word for a hinge, because the whole door of human goodness swings on them.
Full explanation
Out of the many good habits a person can have, four stand out as load-bearing — the ones the rest depend on. Picture a sturdy table: it needs four solid legs, and if any one is missing the whole thing wobbles. The cardinal virtues are those four legs of a well-lived life.
Prudence comes first, and it is not the timid, play-it-safe quality the modern word suggests. It is practical wisdom: the skill of seeing a situation clearly and choosing the right thing to actually do about it. Prudence is the steering wheel for all the other virtues — without it, even good intentions crash, because courage without wisdom becomes recklessness and kindness without wisdom becomes a doormat. It asks the question, given everything that is true here, what is the right move?
Justice is the steady will to give each person what they are genuinely owed — to God the honour due to him, to other people their rights, their dignity, their fair share. A just person is reliable in a deep way: you can trust that they will not cheat you, will keep their word, and will not look away when someone weaker is being wronged. Justice turns goodness outward, toward the rights of others.
Fortitude is courage that lasts. It is not the absence of fear but the strength to do the right thing in spite of fear — to hold the line under pressure, to keep going when the cost is high, to endure suffering for the sake of what is good. And temperance is the inner discipline that keeps our appetites in their proper place: it does not despise good things like food, drink, or pleasure, but it keeps them from running the show. Temperance is the rudder that stops desire from steering us onto the rocks.
These four are human virtues, built by practice over time — though grace heals and strengthens them well beyond what raw willpower could reach. Notice how they balance one another: prudence to see, justice to act rightly toward others, fortitude to stand firm, temperance to stay free. A life with all four is steady, fair, brave, and free — and that is no accident, because these are the hinges every other virtue hangs on.
Why this matters
Most of our moral failures are really a shortage of one of these four. We knew the right thing but did not have the courage (fortitude); we wanted the good of others but were swamped by our own cravings (temperance); we meant well but chose badly (prudence); we were tempted to take what wasn't ours (justice). Naming the four gives you a kind of diagnostic: when you keep stumbling in the same place, you can ask which leg of the table is short and train it directly.
Myth Common misunderstanding
People sometimes treat these as four separate compartments — as if you could be a master of courage while being completely unjust, or perfectly self-controlled while having no wisdom. But the tradition insists they grow together and lean on one another. Courage without prudence is just rashness; self-control without justice can become mere selfishness, a disciplined life lived only for oneself. Real virtue is the four working as a team.

Reflect
Of the four — wisdom to choose well, fairness toward others, courage under pressure, self-control with your appetites — which is the shortest leg of your table right now, and what is one way you could begin to strengthen it this week?
