We must admit, however, that neither wild beasts nor any other creature except man is subject to anger: for, whilst anger is the foe of reason, it nevertheless does not arise in any place where reason cannot dwell. Wild beasts have impulses, fury, cruelty, combativeness: they have not anger any more than they have luxury: yet they indulge in some pleasures with less self-control than human beings.
