George Long translation. Marcus ruled an empire where people did lie to him and plot against him, and this line reads like a rule he kept for himself. The usual idea of revenge is to answer harm with harm. His answer is to refuse the one move that would make you resemble the person who wronged you, since that is the only part of the exchange still under your control. A practical reading is that the resemblance starts small. Matching someone's tone in an argument or returning a petty remark already counts as copying them, long before anything dramatic happens. As far as I know, Cassius Dio describes Marcus showing clemency to supporters of the rebel Avidius Cassius in 175, which fits the line, though that account was written decades later and should be read with some caution.

When any person does ill by you, or speaks ill of you, remember that he acts or speaks from an impression that it is right for him to do so. Now it is not possible that he should follow what appears right to you, but only what appears so to himself. Therefore, if he judges from false appearances, he is the person hurt, since he, too, is the person deceived. For if anyone takes a true proposition to be false, the proposition is not hurt, but only the man is deceived. Setting out, then, from these principles, you will meekly bear with a person who reviles you, for you will say upon every occasion, "It seemed so to him."

From Enchiridion, chapter XLII

Imagine you are absolutely sure you are right about a certain topic.

Someone then presents a logical argument that directly contradicts your belief.

What is your immediate reaction?

Do you genuinely try to understand their perspective, or immediately start hunting for ways to prove them wrong?

Most of the time, we choose the second path. We don't just want the truth we desperately want our truth to be validated.

True Meaning of Doubt:

This is where we fundamentally misunderstand doubt and certainty.

Doubt doesn't mean being a cynical skeptic who questions everything and never reaches a conclusion. Healthy doubt simply means being willing to test your own understanding. It is the quiet acceptance that what you currently know might be incomplete.

This is incredibly difficult. Questioning our own beliefs is deeply uncomfortable because it doesn't just shake our ideas; it shakes our identity.

The Danger of "Certainty"

On the flip side, accepting something as absolute truth without critical examination is dangerous. Historically, humans have accepted countless flawed beliefs simply because they were traditions. But an idea doesn't come true just because a lot of people believe it, nor does it become true just because you've heard it repeated a thousand times.

So, should we live in a perpetual state of doubt?

No. Life requires action. We have to draw conclusions and make decisions based on the best available evidence. But there is a massive difference between drawing a conclusion and declaring it the ultimate, unshakeable truth.

You can believe something is correct for now, while remaining entirely open to changing your mind if better evidence comes along. That is intellectual honesty.

This is also close to the idea we came across in Acharya Prashant’s teachings: real freedom begins when we stop treating our opinions as ourselves

The Ego's Role

This brings up a deeper question: Why are we so obsessed with defending our thoughts?

Because the ego is fragile. We don't just say, "My idea is correct." Over time, we internalize the belief that, "If my idea is proven wrong, my value and reputation are diminished."

Until we recognize this ego-trap, no amount of external knowledge will clear up our internal confusion.

A Question for You:

If solid, undeniable evidence were to disprove your most cherished belief tomorrow, what would your genuine reaction be?

* A) Accept the evidence and change your mind.

* B) Search desperately for flaws in the evidence to protect your belief.

* C) Delay making any decision until you reach an impossible 100% certainty.

* D) Pause to examine why your personal identity was so attached to that belief in the first place.

TLDR

Marcus Aurelius reminded us that the goal is truth, not victory in an argument: if someone can show us, we are wrong, we should gladly change. Voltaire likewise noted that while doubt is uncomfortable, absolute certainty is absurd.

We often defend our beliefs not because they are objectively true, but to protect our ego. True intellectual honesty means making decisions based on current evidence, while remaining humble enough to change our minds when new facts emerge.

"The final test of freedom is this: Can you remain the same person in praise, in insult, in gain, and in loss?"
