Stoic ideas
Premeditatio malorum

The meaning
The phrase translates roughly as the premeditation of evils. You think through the difficulties a day or a season may bring before they arrive. Many modern writers call it negative visualization.
Marcus Aurelius and the morning
The second book of the Meditations opens with a rehearsal.
“Begin the morning by saying to thyself, I shall meet with the busybody, the ungrateful, arrogant, deceitful, envious, unsocial. All these things happen to them by reason of their ignorance of what is good and evil.”
The difficulty is named while the day is still ahead, and the reason for it comes with the name. By the time the busybody or the ungrateful person appears, you have already met them once.
Seneca on being ready
Seneca writes about the same readiness in his consolations and essays.
“Our mind ought always to be on the alert, and while it ought never to fear what is certain to happen, it ought always to be ready for what may happen at any time.”
“Know then that every station of life is transitory, and that what has ever happened to anybody may happen to you also.”
Both passages ask for an honest picture of what can happen to a person. Neither asks you to dwell on it. The mind is kept ready, which leaves it free for the day.
Ready for what is sudden
“The art of life is more like the wrestler's art than the dancer's, in respect of this, that it should stand ready and firm to meet onsets which are sudden and unexpected.”
The wrestler's art is to stand ready for what cannot be foreseen. A morning rehearsal does the same: you cannot foresee the day, and you can decide how you will stand.
How it differs from worry
Worry repeats and has no plan attached. The rehearsal happens once, in the morning. It names one specific thing and ends with how you will meet it. When the page is closed, the day begins.
How to practice it
- Before the day starts, look at what is on it: meetings, conversations, travel, errands.
- Pick one or two things that could realistically go wrong.
- Write each in a sentence, followed by how you will meet it.
- Close the page and begin.
For example: "The 3 o'clock conversation may turn sharp. I will speak slowly and say what I need in one sentence." That is the whole entry.
Keep it small. A rehearsal that fills a page starts to look like worry. If nothing on the day stands out, write that it looks ordinary and how you want to meet whatever comes. The entry can be different every morning.
How Doctrine helps
On Today, Doctrine shows a card headed "Before the day" with one question: "What could go wrong today, and how will you meet it?" You write a line and tap "Keep it". If you turn on reminders, the morning one is titled "Before the day: what could go wrong?" at the time you choose.
The line stays with that day, and you can open the day again later to read it. When something does go wrong, the dichotomy of control helps you sort what is yours to act on. The guide to practicing Stoicism every day shows where the morning line sits in the rest of the day, and life in weeks shows the weeks that the days add up to. Your writing stays on your phone, with no account and no AI.
Questions
What does premeditatio malorum mean?
Roughly, the premeditation of evils: thinking ahead about what could go wrong. In Stoicism it means rehearsing difficulties in advance so that you can meet them with a plan.
Did the Stoics use the Latin term?
The Latin label comes from later writers. Marcus Aurelius, Seneca and Epictetus describe the habit in their own words.
Is it the same as negative visualization?
Negative visualization is the term many modern writers use for this habit. The Stoic version ends with how you will meet what you imagined.
How is it different from worrying?
Worry repeats and carries no plan. The rehearsal happens once, in the morning, names a specific thing and ends with an answer to it.
How long does it take?
About a minute. One or two sentences are enough.
Keep the practice, one week at a time.
Doctrine gives you a line each morning, Seneca's three questions each evening and a name for every week, on a grid of your whole life. For iPhone, seven days free.
