To animals not only human virtues but even human vices are forbidden: their whole constitution, mental and bodily, is unlike that of human beings...they possess intellect, the greatest attribute of all, but in a rough and inexact condition. It is, consequently, able to grasp those visions and semblances which rouse it to action, but only in a cloudy and indistinct fashion. Their impulses and outbreaks are violent, and that they do not feel fear, anxieties, grief, or anger, but some semblances of these feelings: wherefore they quickly drop them and adopt the converse of them: they graze after showing the most vehement rage and terror, and after frantic bellowing and plunging they straightaway sink into quiet sleep.

To no creature besides man has been given wisdom, foresight, industry, and reflection.

Dumb creatures have not human feelings, but have certain impulses which resemble them: for if it were not so, if they could feel love and hate, they would likewise be capable of friendship and enmity, of disagreement and agreement. Some traces of these qualities exist even in them, though properly all of them, whether good or bad, belong to the human breast alone.

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.

Thus they are deceived by the likeness of blows, and are appeased by the pretended tears of those who deprecate their wrath, and thus an unreal grief is healed by an unreal revenge.

Everything of this sort is not anger, but the semblance of anger, like that of boys who want to beat the ground when they have fallen upon it, and who often do not even know why they are angry, but are merely angry without any reason or having received any injury, yet not without some semblance of injury received, or without some wish to exact a penalty for it.

What, if you were to pass from the consideration of those single men against whom anger has broken out to view whole assemblies cut down by the sword, the people butchered by the soldiery let loose upon it, and whole nations condemned to death in one common ruin... as though by men who either freed themselves from our charge or despised our authority?

See the foundations of the most celebrated cities hardly now to be discerned; they were ruined by anger. See deserts extending for many miles without an inhabitant: they have been desolated by anger.

Next, if you choose to view its results and the mischief that it does, no plague has cost the human race more dear

Other vices can be concealed and cherished in secret; anger shows itself openly and appears in the countenance, and the greater it is, the more plainly it boils forth. Do you not see how in all animals certain signs appear before they proceed to mischief, and how their entire bodies put off their usual quiet appearance and stir up their ferocity? Boars foam at the mouth and sharpen their teeth by rubbing them against trees, bulls toss their horns in the air and scatter the sand with blows of their feet
