In the Summa Theologiae, Medieval theologian Thomas Aquinas said Anger is “the name of a passion. A passion of the sensitive appetite is good in so far as it is regulated by reason, whereas it is evil if it set the order of reason aside.” (2, 158, ad 2)
In The Canterbury Tales, Geoffrey Chaucer called Anger “the fervent blood of Man yquyked in his herte, thurgh which he wole harm to hym that he hateth./ For certes, the herte of man, by eschawfynge and moevynge of his blood, wexeth so trouble that he is out of alle juggement of resoun.” (The Parson’s Tale)
