8.10.23   For if there he so many contrary natures as there be conflicting wills, there shall now be not two only, but many. If a man deliberate whether he should go to their conventicle or to the theatre, these Manichees cry out, Behold, here are two natures: one good, draws this way; another bad, draws back that way. For whence else is this hesitation between conflicting wills? But I say that both be bad: that which draws to them, as that which draws back to the theatre. But they believe not that will to be other than good, which draws to them. What then if one of us should deliberate, and amid the strife of his two wills be in a strait, whether he should go to the theatre or to our church? would not these Manichees also be in a strait what to answer? For either they must confess (which they fain would not) that the will which leads to our church is good, as well as theirs, who have received and are held by the mysteries of theirs: or they must suppose two evil natures, and two evil souls conflicting in one man, and it will not be true, which they say, that there is one good and another bad; or they must be converted to the truth, and no more deny that where one deliberates, one soul fluctuates between contrary wills.
