Loss usually means something is gone. A person, a job, a version of your life you assumed would keep going. The word has a one-way feeling to it, as if the world got smaller and stayed that way.
Marcus Aurelius, it seems, wanted to swap that definition for a different one, and the swap is the whole point of the line: call it change instead of loss, and the door stops feeling permanently shut.
A note before going further: we’re not clinicians, psychologists, or grief counsellors, and this is a piece of reading and reflection on an old idea and some recent research, not advice. The studies mentioned describe patterns across groups of people, and a pattern across a population is never a prescription for what any one reader should do with their own grief.
Loss as change
The line opens section 35 of Book 9 of the Meditations, in the classic George Long translation. In full, the Stoic emperor wrote: “Loss is nothing else than change. But the universal nature delights in change, and in obedience to her all things are now done well.”
The Meditations were not a book written for readers but private notes to himself, a philosopher talking himself through the day. This isn’t a settled fact about grief. It’s one man’s Stoic view, and he’s arguing a case, mostly to himself.
The case goes like this: nothing you have ever held was permanent to begin with. The thing you call loss is the same process that grew the thing in the first place. In the Stoic picture, nature isn’t indifferent to change, it’s fond of it, and reshuffling is just what it does. Frame the event that way and the sense of a one-way door closing starts to soften.
It doesn’t pretend the loss isn’t real. Marcus isn’t saying nothing happened. He’s saying we’ve filed it under the wrong heading. Call it change instead of loss and you’ve moved a fixed ending back inside a process that never stopped.
What modern psychology calls the same skill
Strip the poetry out of the line and you’re left with something psychologists study directly: the ability to accept a hard experience rather than fight it.
In one form of therapy, called Acceptance and Commitment Therapy, that willingness has a specific meaning. Researchers led by Nikolaus Willi describe acceptance as “a willingness to contact inner experiences with a more welcoming stance instead of fighting or avoiding them.” That’s close to what Marcus is doing on the page: letting the change be a change instead of bracing against it.
Psychologists have a name for the broader idea, too. They call it psychological flexibility, which roughly means the capacity to cope with, accept, and adjust to hard situations. In the broader psychological-flexibility literature, greater flexibility is associated with better mental-health outcomes, including lower anxiety and depression, while rigidity and avoidance track the other way — though these are associations, not causal findings. Our read of that is support, not proof. These are patterns across groups, and adjusting well to a hard season is not a switch anyone flips at will.
Applying it when a real loss lands
When something is taken away, the first Stoic move is to remember that change itself is not an interruption of life. It is what life has been doing all along.
A job ends. A relationship changes shape. Children grow up and leave home. A body that once did something easily begins to slow down. A house is sold, a friendship drifts, a familiar place disappears. None of these feel identical, and some hurt far more than others, but Marcus’s point is that they belong to the same larger process. Things come together, stay for a while, and then become something else.
We usually notice this most clearly when the change is harmless. Summer becomes autumn. A child becomes an adult. A field is cut and grows back. In those cases, change looks ordinary. It is only when the thing changing is something we wanted to keep that we tend to call the same process loss.
That is what makes the line more interesting than a simple instruction to “think positively.” Marcus is asking us to place the painful event back inside nature rather than treat it as an exception to nature. The relationship ending, the career changing, growing old: these are not departures from the rule. They are the rule.
That does not make every change welcome. Natural does not mean painless, fair, or good. But the Stoic move is to notice that permanence was never really on offer. The thing we loved was always changing while we had it, and so were we.
Acceptance, in that sense, is less about convincing yourself that a loss does not matter and more about giving up the demand that life should have remained as it was. Something changed because everything does. The work is not to pretend otherwise, but to learn how to live inside the new shape of things.
If a loss has landed on you and the grief feels stuck rather than slowly loosening, a qualified counsellor or therapist is worth talking to.
