The sentence says: "So the virtuous man will not take what is said by others, or if he does he will nonetheless reprove them." What is the definition of take here? On Lexico, I find 4.9 might be appropriate: regard or view in a specified way; On MW, I find 18a might be appropriate: deal with.
My own understanding is "take what others[dishonorable] said seriously". Did I understand it correctly? Thank!
