Of the Manichaeans

Is matter, in respect of alteration, an evil cause? It is thus proved that it is not more evil than good. For let the beginning of the, change be from evil. Thus the change is from this to good through that which is indifferent. But let the alteration be from good. Again the beginning goes on through that which is indifferent. Whether the motion be to one extreme or to the other, the method is the same, and this is abundantly set Forth. All motion has to do with quantity; but quality is the guide in virtue and vice. Now we know that these two are enerically distinguished. But are God and matter alone principles, or floes there remain anything else which is the mean between these two? For it there is nothing, these things remain unintermingled one with another. And it is well said that if the extremes are intermingled, there is a necessity for some thing intermediate to connect them.
