Why does Marcus Aurelius say a man must stand erect and not be kept erect by others?

The line comes at the end of a passage where Marcus is describing the kind of person he wants to be: someone who works without complaint, without empty ornament in his thoughts, and without needing anyone else's approval. He pictures a soldier who has taken his post like a man waiting for the signal that calls him from life, ready to go, needing neither oath nor any man's testimony (Meditations 3.5). The sentence right before the one about standing erect makes the target explicit: be cheerful also, and seek not external help nor the tranquility which others give (Meditations 3.5).

So when Marcus writes that a man must stand erect, not be kept erect by others, he is not talking about posture. He is talking about where your steadiness comes from. A person who is kept erect by others needs something outside himself to hold him up: praise, company, reassurance, someone else's calm rubbing off on him. Take that support away and he sways or falls. A person who stands erect supplies his own uprightness. It comes from his own judgments, his own sense of what matters, not from what other people supply him.

The common misreading is to hear this as a call to toughness or isolation, the stiff-upper-lip Stoic who does not need anyone. That is not what the passage says. Marcus is still describing a man engaged in matter political, a Roman, a ruler, someone embedded in public life and its obligations (Meditations 3.5). The line is not against relationships or cooperation. It is against depending on others for your inner stability. You can work alongside people, serve them, even need their help for practical things, while still being the one source of your own composure. The dependence Marcus rejects is specifically the tranquility others give, not the company they provide.

This connects to a claim Marcus makes elsewhere about what actually makes a life better or worse. He argues that death, life, honor, dishonor, pain, and pleasure happen equally to good people and bad people, and so cannot themselves be good or evil, because nothing that leaves your character untouched can make your life better or worse (Meditations 2.11). If that is true, then other people's opinions of you, their comfort, their approval, belong to the same category. They are not up to you, and they cannot make you a better or worse person. Building your uprightness on them is building on the wrong material.

What changes for someone who takes this seriously is where they look when they feel unsteady. The instinct, when anxious or discouraged, is to seek reassurance: a friend's encouragement, a boss's approval, a crowd's agreement. Marcus is not saying refuse these things if they are offered. He is saying do not need them. Ask instead what your own judgment says about the situation, and let that be what holds you up. If a decision still looks right to you when no one is around to confirm it, you are standing on your own. If it only feels right after someone else validates it, you were being kept erect.

The practical version of this is small and repeatable. Before you ask for reassurance about something you already believe, pause and check what you actually think, independent of what anyone else will say. That check is the whole practice. A man then must stand erect, not be kept erect by others (Meditations 3.5).
