notice even of Pythagoras, as we infer from his zeal for music, which he introduced to calm and soothe the soul, as knowing that it was not altogether amenable to precept and instruction, or redeemable from vice only by reason, but that it needed some other persuasion and moulding and softening influence to co-operate with reason, unless it were to be altogether intractable and refractory to philosophy. And Plato saw very plainly and confidently and decidedly that the soul of this universe is not simple or uncomposite or uniform, but is made up of forces that work uniformly and differently, in the one case it is ever marshalled in the same order and moves about in one fixed orbit, in the other case it is divided into motions and orbits contrary to each other and changing about, and thus generates differences in things. So, too, the soul of man, being a part or portion of the soul of the universe, and compounded upon similar principles and proportions, is not simple or entirely uniform, but has one part intelligent and reasoning, which is intended by nature to rule and dominate in man, and another part unreasoning, and subject to passion and caprice, and disorderly, and in need of direction. And this last again is divided into two parts, one of which, being most closely connected with the body, is called desire, and the other, sometimes taking part with the body, sometimes with reason, lending its influence against the body, is called anger. And the difference between reason and sense on the one hand, and anger and desire on the other, is shown by their antipathy to one another, so that they are often at variance with one another as to what is best.² These were at first³ the views of Aristotle, as is clear from his writings, though afterwards he joined anger to desire, as if anger were nothing but a desire and passion for revenge. However, he always considered the emotional and unreasoning part of the soul as distinct from the reasoning, not that it is altogether unreasoning as the perceptive, or nutritive, or vegetative portions of the soul, for these are always deaf and disobedient to reason, and in a certain sense are off-shoots from the flesh, and altogether attached to the body; but the emotional, though it is destitute of any reason of its own, yet is naturally
