Two thousand years before anyone told you to count to ten, a Roman philosopher wrote a whole book about anger. Seneca's On Anger (De Ira) was written in the first century AD and addressed to his brother Novatus. It's one of the most practical things the Stoics left behind: less theory, more "here's what to do when you're about to lose it".
What Seneca actually wrote
The line most people know is this:
"The greatest remedy for anger is delay."
On Anger, Book II, ch. 29: "maximum remedium irae mora est."
Unlike many quotes credited to Stoics online, this one is genuinely his. His reasoning is simple: anger is strongest in its first rush. Give it time and that first heat fades, and you can judge what actually happened instead of reacting to how it felt.
Anger as a "brief madness"
Seneca opens the book by noting that some wise men have called anger a brief madness (brevis insania). His point isn't that angry people are bad. It's that while anger lasts, you aren't really in charge of your own decisions. That's why he treats it as something to manage before it starts, not something to vent once it's here.
Three Stoic habits from On Anger
- Wait before you answer. Delay is the whole strategy. Don't send the message, don't make the decision, don't reply in the meeting. Let the first wave pass.
- Ask whether you've actually been wronged. Seneca argues that much of our anger comes from misreading situations: assuming intent, taking things personally, expecting the world to go our way.
- Review your day at night. In Book III he describes a habit he took from the philosopher Sextius: each evening, go over the day and ask where you lost your temper and how you could have handled it better. It's a journaling practice two thousand years old.

Why Seneca thought anger never helps
In his day, many people defended anger as useful. It made soldiers braver, judges stricter and speakers more persuasive. Seneca disagreed with every one of those claims. His argument is simple: anything anger can do, reason can do better, without the damage. A judge can punish without rage. A soldier can fight with skill rather than fury. And a person who needs anger to act is relying on something that disappears the moment it cools down.
Anger and other people's faults
One of the most modern ideas in On Anger is how Seneca deals with other people's mistakes. If we got angry at every fault we saw, he says, we would never stop being angry, because everyone makes mistakes, including us. So instead of judging each person, forgive the whole human race in advance. It sounds lofty, but it's practical: expecting people to be imperfect is the fastest way to stop being surprised, and offended, when they are.
How to use this today
- Before sending an angry email, save it as a draft and read it again tomorrow. That's Seneca's "delay" in one step.
- When someone lets you down, ask: did they mean it, or is this ordinary human error? Quote #7 above is about exactly this.
- At the end of the day, try Sextius's two questions. They take a minute, and they work better than any journaling app.
