317. ( iii) _All that a man is persuaded of and confirms remains with him as his own._ Many believe that no truth can be seen by man without confirmations of it, but this is false. In civic and economic matters in a kingdom or republic what is useful and good can be seen only with some knowledge of its numerous statutes and ordinances; in judicial matters only with knowledge of the law; and in natural subjects, like physics, chemistry, anatomy, mechanics and others, only on acquaintance with those sciences. But in purely rational, moral and spiritual matters, truths appear in light of their own, if man has become somewhat rational, moral and spiritual through a suitable education. This is because everyone as to his spirit, which is what thinks, is in the spiritual world and is one among those there, consequently is in spiritual light, which enlightens the interiors of his understanding and, as it were, dictates. For spiritual light in essence is the divine truth of the Lord's divine wisdom. Thence it is that man can think analytically, form conclusions about what is just and right in matters of judgment, see what is honorable in moral life and good in spiritual life, and see many truths, which are darkened only by the confirmation of falsities. Man sees them almost as readily as he sees another's disposition from his face or perceives his affections from the sound of his voice, with no further knowledge than is implanted in one. Why should not man in some measure see from influx the interiors of his life, which are spiritual and moral, when there is no animal that does not know by influx all things necessary to it, which are natural? A bird knows how to build its nest, lay its eggs, hatch its young and recognize its food, besides other wonders which are named instinct. 318. How this state is changed, however, by confirmations and consequent persuasions will be told now in this order: 1. There is nothing that cannot be confirmed, and falsity is confirmed more readily than truth. 2. Truth does not appear when falsity has been confirmed, but falsity is apparent from confirmed truth. 3. The ability to confirm whatever one pleases is not intelligence but only ingenuity, to be found in the worst of men. 4. Confirmation may be mental and not at the same time volitional, but all volitional confirmation is also mental. 5. Confirmation of evil both volitional and intellectual causes man to believe that one's own prudence is everything and divine providence nothing, but not confirmation solely intellectual. 6. Everything confirmed by the will and at the same time by the understanding, remains to eternity, but not what has been confirmed only by the understanding.
