“Everything We Hear Is an Opinion, Not a Fact”: Not Marcus Aurelius
By "Everything we hear is an opinion, not a fact. Everything we see is a perspective, not the truth."
It is one of the most shared Marcus Aurelius quotes online, and it is not in the Meditations. Not in any translation. When PolitiFact checked it in 2019, the philosopher Dirk Baltzly of the University of Tasmania put it bluntly: "The emperor was a stoic—not a skeptic." And: "I’d call BS on that quote."
What makes it worth a page is not just that it is fake. It is that the fake says close to the opposite of what Marcus believed, while borrowing words that really are in the book.
The two lines it seems to grow from
Nobody has traced who first wrote the modern version. But two short passages in the Meditations are the obvious ancestors, and both have been pointed to by people who looked.
The first is Book II, section 15, which Thomas Colligan identified in a 2018 piece for Modern Stoicism. Here it is in George Long’s 1862 translation:
Remember that all is opinion. For what was said by the Cynic Monimus is manifest: and manifest too is the use of what was said, if a man receives what may be got out of it as far as it is true.Meditations II.15, trans. George Long
The second is the end of Book IV, section 3, which PolitiFact’s fact-check cited:
The universe is transformation: life is opinion.Meditations IV.3, trans. George Long
So "opinion" really is there, twice, and so is a short line about everything being what you make of it. You can see how someone compressing those into a quote card might arrive at the viral wording.
What the lines actually say
Look at II.15 again. Marcus is quoting someone else, Monimus, a Cynic philosopher, and he immediately adds a condition: the saying is useful "as far as it is true." He is not endorsing it outright. He is telling himself to take the part of it that holds.
And the part that holds, for a Stoic, is about judgment. IV.3 makes it plain just before the line about opinion: "our perturbations come only from the opinion which is within." The world does what it does. What upsets you is the verdict you add to it. That verdict is yours, which means you can examine it and change it.
That is a claim about what you control. It is not a claim that nothing is true.
Why the rewrite gets Stoicism backwards
The viral version says that what you see is "a perspective, not the truth." The Stoics held almost exactly the reverse. Their theory of knowledge rested on the idea that some impressions are clear enough to grasp reality as it is, and that a careful mind can learn to tell those from the ones it should not trust. That confidence in reason is why Stoicism is a practice at all: if every perception were mere perspective, there would be nothing to correct your judgments against.
Colligan made the same point in 2018: Marcus meant that we control our judgments about external things, not that all perspectives are equally valid, because the Stoics believed reason gives an objective standard for whether a judgment is right.
So the quote is not a loose paraphrase of Marcus. It is a different philosophy, closer to skepticism or modern relativism, wearing his name.
What to quote instead
If you want the idea Marcus actually held, IV.3 is the one: "our perturbations come only from the opinion which is within." It is checkable, it is his, and it is more useful, because it points at something you can do about it.
For the same idea from Epictetus, see what he actually said about reactions. The full list of Stoic quotes that are not Stoic has the rest, and our quote checker will tell you whether a line is in our library before you share it.
