The Soul Wanderers

Today I'd like to share a passage from Marcus Aurelius's Meditations that is particularly insightful (Marcus Aurelius was a Roman Emperor and Stoic philosopher). I'm not going to explain it or talk about it because it's self-explanatory, though certainly very useful:

From Meditations, Book Nine, 42:
"When you run up against someone else's shamelessness, ask yourself this: Is a world without shameless people possible?
No.
Then don't ask the impossible. There have to be shameless people in the world. This is one of them.
The same for someone vicious or untrustworthy, or with any other defect. Remembering that the whole class has to exist will make you more tolerant of its members.
Another useful point to bear in mind: What qualities has nature given us to counter that defect? As an antidote to unkindness it gave us kindness. And other qualities to balance other flaws.
And when others stray off course, you can always try to set them straight, because every wrongdoer is doing something wrong--doing something the wrong way.
And how does it injure you anyway? You'll find that none of the people you're upset about has done anything that could do damage to your mind. But that's all that "harm" or "injury" could mean. Yes, boorish people do boorish things. What's so strange or unheard-of about that? Isn't it yourself you should reproach--for not anticipating that they'd act this way? The logos gave you the means to see it--that a given person would act a given way--but you paid no attention. And now you're astonished that he's gone and done it. So when you call someone 'untrustworthy' or 'ungrateful,' turn the reproach on yourself. It was you who did wrong. By assuming that someone with those traits deserved your trust. Or by doing them a favor and expecting something in return, instead of looking to the action itself for your reward. What else did you expect from helping someone out? Isn't it enough that you've done what your nature demands? You want a salary for it too? As if your eyes expected a reward for seeing, or your feet for walking. That's what they were made for. By doing what they were designed to do, they're performing their function. Whereas humans were made to help others. And when we do help others--or help them to do something--we're doing what we were designed for. We perform our function."
