Welcome The Friendly Critic

If any man is able to convince me and show me that I do not think or act right, I will gladly change; for I seek the truth, by which no man was ever injured. But he is injured who abides in his error and ignorance.

Marcus Aurelius wrote this to himself during his years on campaign along the Danube frontier, in the private notebook now known as Meditations. He is arguing against his own resistance to being corrected: if someone can show him he is wrong, he will change gladly, because seeking truth never harms anyone, while clinging to error does. This is the emperor's version of daily self-examination, staying open to what a clear-eyed friend or critic might see in his conduct that he cannot see in himself. Stoics practiced this kind of audit regularly, reviewing their actions honestly, naming what was done well, what fell short, and what was left undone. The aim was never guilt but calibration, so character formed on purpose rather than by drift.
