XXV. (91) Let this then be enough to say concisely about the essence of the soul. And now proceeding in regular order, we will explain the expression, that “the voice of his blood cries out,” in this manner, –of our soul, one part is dumb, and one part is endowed with utterance. All that part which is devoid of reason is likewise destitute of voice, but all that part which is rational is capable of speech, and that part alone has formed any conception of God; for, by the other parts of us, we are not able to comprehend God, or any other object of the intellect. (92) Of our vivifying power, therefore, of which the blood is, as it were, the essence, one portion has particular honour, namely, that of speech and reason; I do not mean the stream which flows through the mouth and tongue, but I speak of the fountain itself, from which the channels of utterance are, in the course of nature, filled. And this fountain is the mind; by means of which, all our conversations with and cries to the living God take place, at one time being voluntary, and at another involuntary. (93) But he, as a good and merciful God, does not reject his suppliants, and most especially he does not, when they, groaning at the Egyptian deeds and passions, cry to him in sincerity and truth. For at such a time Moses says that, “their words go up to God,”{30}{#ex 2:21.} and that he listens to them, and delivers them from the evils that surround them. (94) But that all these things should happen when the king of Egypt dies, should be a most strange thing; for it would be natural that when the tyrant died, all those who have been tyrannised over by him should rejoice and exult; but at that time they are said to groan. “For after many days the king of Egypt died, and the children of Israel Groaned.”{31}{#ex 2:25.} (95) Now here, if we look merely at the words, the expression does not appear to be reasonable; but if we have regard to the faculties in the soul, then its consistency is discovered. For as long as he who scatters abroad and dissipates the opinions about good things, namely, Pharaoh, is vigorous in us, and appears in a sound and healthy state, if indeed we can say that any wicked man is in such a condition, we receive pleasure, driving temperance away from our borders. But when he loses his strength, and in a manner dies, he who has been the cause of men’s living in a filthy and lascivious manner, then we, fixing our eyes on modesty of life, bewail and groan over ourselves on account of our former way of living; because the, honouring pleasure before virtue, we joined a mortal life to an immortal one; and the law taking pity on our continued lamentation, gently receives our suppliant souls, and easily drives away the Egyptian calamities which are brought upon them by the passions.

XXVI. (96) But on him who is incapable of receiving repentance on account of the enormity of the pollution which he has incurred by the murder of his brother, namely, on Cain, he lays well-deserved and fitting curses; for in the first place he says to him, “And now, cursed art thou upon the Earth:”{32}{#ge 4:11.} showing first of all that he is polluted and accursed, not now for the first time when he has committed the murder, but that he was so before, the moment that he conceived the idea of it, the intention being of equal importance with the perfected action; (97) for as long as we only conceive wicked things in the bad imagination of our minds, still, during that time, we are guilty of thoughts only, for the mind is capable of being changed even against its will; but when performance is added to the intention that has been conceived, then our deliberate purpose becomes also guilty; for this is the chief distinction between voluntary and involuntary sin. (98) But the scripture here pronounces that the mind shall be accursed, not from anything else, but from the earth; for of all the most grievous calamities which can happen to it, the earthly portion which exists in each of us is found to be the cause. At all events, when the body is afflicted with disease, it adds the miseries which are derived from itself, and so fills the mind with grief and despondency; or, on the other hand, if it has grown fat immoderately through enjoyment of pleasures, it makes all the faculties of the mind duller for the comprehension of nobler objects. (99) For, indeed, each of the outward senses is capable of receiving injury; for either a man beholding beauty is wounded by the darts of love, which is a terrible passion; or else, perhaps, if he hears of the death of any one related to him by birth, he is bowed down by sorrow: very often, too, taste gets the mastery of a man, when it is either tortured by disagreeable flavours, or weighed down by the multitude of delicacies. And why need I speak of the impetuous passions, which tend to the connexion of the two sexes? These have destroyed whole cities, and countries, and mighty nations of the earth; to which fact nearly the whole multitude, both of poets and of historians, bears abundant testimony.
