From Marcus Aurelius (121–180 AD), Roman emperor from 161 to 180, Meditations (170-180):
When another blames you or hates you, or people voice similar criticisms, go to their souls, penetrate inside and see what sort of people they are. You will realize that there is no need to be racked with anxiety that they should hold any particular opinion about you
From Marcus Aurelius (121-180), Stoic philosopher and Roman Emperor, Meditations (161-180):
How much time he gains who does not look to see what his neighbor says or does or thinks, but only at what he does himself, to make it just and holy.
From Marcus Aurelius (121-180),Emperor of Rome from 161 to 180, practitioner of Stoicism, Meditations:
If someone is able to show me that what I think or do is not right, I will happily change, for I seek the truth, by which no one was ever truly harmed. It is the person who continues in his self-deception and ignorance who is harmed.
Excellent advice from Marcus Aurelius (121-180), Stoic philosopher, and Roman Emperor from 161 to his death in 180, Meditations:
