XXII. (2.150) But, come now, this hunger is lighter evil than thirst, inasmuch as it has love and desire for its comforters; but when, through the desire of drinking, it is necessary to satisfy one’s self with that other fountain, the water of which is dirty and unwholesome, then it is indispensable for the drinkers, being filled with a bitter-sweet pleasure, to live an unenviable life, betaking themselves to pernicious things as though they were advantageous, from ignorance of what is really desirable. (2.151) But the impetuous course of these evils is most grievous when the irrational powers of the soul attack the powers of the reason and get the better of them; (2.152) for as long as the herds of oxen obey their drivers, and the flocks obey their shepherds, and the goats obey the goatherds, the herds and all belonging to them go on well; but when the herdsmen who are appointed to look after the cattle become weaker than the beasts committed to their care, then everything goes wrong, and instead of regularity there arises irregularity, and disorder in the place of order, and confusion instead of steadiness, and disturbance in the place of good arrangement, since there is no longer any lawful superintending power properly established; for if there had been such a thing, it would have been destroyed before this time. (2.153) What then? Do we not think that even in ourselves there is a herd of irrational cattle, inasmuch as the irrational multitude of the soul is deprived of reason, and that the shepherd is the governing mind? But as long as that is vigorous and competent to act as the manager of the herd, everything goes on in a just, and prosperous, and advantageous manner; (2.154) but when any weakness or want of power supervenes to the king, then it follows of necessity that the subjects also labour with a like infirmity; and when they most completely seem to be in enjoyment of liberty, then they are a prize, lying most entirely ready for any one who pleases to contend for it to seize; for the natural course is for anarchy to be treacherous, and for government to be salutary, especially in a state where law and justice are honoured. And this is such a state as is consistent with reason.
