Forgiveness restores peace
Certainly true!
In fact, if Plutarch is correct, Epicureans were even known to say, “Let even this have forgiveness” more literally it means "Let even this have a mutual understanding" which is a certainly a helpful mantra to have in mind for working well with others.
"ἐχέτω δὲ συγγνώμην καὶ τοῦτο" – ὡς λέγουσι!
“Let even this have pardon" – as they say!
Plutarch, Against Colotes, 1118D
