that they themselves concede that the unreasoning element is something different from judgement, in that they allow that by it passion becomes greater and more violent, and while they quarrel about the name and word they give up the thing itself to those who maintain that the emotional and unreasoning part of the soul is distinct from the reasoning and judging element. And in his treatise on Anomaly,[242] Chrysippus, after telling us that anger is blind, and frequently does not let one see what is obvious, frequently also obscures what we do get a sight of, goes on to say, "The encroachment of the passions blots out reason, and makes things look different to what they should look, violently forcing people on unreasonable acts." And he quotes as witness Menander, who says, "Alas! poor me, wherever were my brains in my body at the time when I chose that line of conduct, and not this?" And Chrysippus proceeds, "Though every living creature endowed with reason is naturally inclined to use reason and to be governed by it on every occasion, yet often do we reject it, being borne away by a more violent impulse;" thus admitting what results from the difference between passion and reason. For otherwise it is ridiculous, as Plato says, to argue that a man is sometimes better than himself, sometimes worse, sometimes master of himself, sometimes not master of himself. Sec. XI. For how is it possible that the same person can be both better and worse than himself, both master of himself and not master, unless everyone is in some way twofold, having in himself both a better and worse self? For so he that makes the baser element subject to the better has self-control and is a superior man, whereas he who allows the nobler element of the soul to follow and be subservient to the incorrigible and unreasoning element, is inferior to what he might be, and is called incontinent, and is in an unnatural condition. For by nature it appertains to reason, which is divine, to rule and govern the unreasoning element, which has its origin from the body, which it also naturally resembles and participates in its passions, being placed in it and mixed up with it, as is proved by the impulses to bodily delights, which are always fierce or languid according to the changes of the body. And so it is that young men are keen and vehement in their desires, being red hot and raging from their fulness of blood and animal heat, whereas with old men the liver, which is the seat of desire, is dried up and weak and feeble, and reason has more power with them than passion which decays with the body. This principle also no doubt characterizes the nature of animals as regards the sexual appetite. For it is not of course from any fitness or unfitness of opinions, that some animals are so bold and resolute in the presence of danger, while others are helpless and full of fear and trembling; but this difference of emotion is produced by the workings of the blood and spirit and body, the
