Among us, on the other hand, 'the righteous man lives by faith.' Now, if you take away positive affirmation, you take away faith, for without positive affirmation nothing is believed. And there are truths about things unseen, and unless they are believed, we cannot attain to the happy life, which is nothing less than life eternal. It is a question whether we ought to argue with those who profess themselves ignorant not only about the eternity yet to come but also about their present existence, for they [the Academics] even argue that they do not know what they cannot help knowing. For no one can 'not know' that he himself is alive. If he is not alive, he cannot 'not know' about it or anything else at all, because either to know or to 'not know' implies a living subject. But, in such a case, by not positively affirming that they are alive, the skeptics ward off the appearance of error in themselves, yet they do not make errors simply by showing themselves alive; one cannot err who is not alive. That we live is therefore not only true, but it is altogether certain as well. And there are many things that are thus true and certain concerning which, if we withhold positive assent, this ought not to be regarded as a higher wisdom but actually a sort of dementia.Augustine Of Hippo

In this universe, even what is called evil, when it is rightly ordered and kept in its place, commends the good more eminently, since good things yield greater pleasure and praise when compared to the bad things. For the Omnipotent God, whom even the heathen acknowledge as the Supreme Power over all, would not allow any evil in his works, unless in his omnipotence and goodness, as the Supreme Good, he is able to bring forth good out of evil. What, after all, is anything we call evil except the privation of good? In animal bodies, for instance, sickness and wounds are nothing but the privation of health. When a cure is effected, the evils which were present (i.e., the sickness and the wounds) do not retreat and go elsewhere. Rather, they simply do not exist any more. For such evil is not a substance; the wound or the disease is a defect of the bodily substance which, as a substance, is good. Evil, then, is an accident, i.e., a privation of that good which is called health. Thus, whatever defects there are in a soul are privations of a natural good. When a cure takes place, they are not transferred elsewhere but, since they are no longer present in the state of health, they no longer exist at all.Augustine Of Hippo

This, then, is true liberty: the joy that comes in doing what is right. At the same time, it is also devoted service in obedience to righteous precept.Augustine Of Hippo
