[15] These and countless other activities are secret operations of the soul in the body. Man has no sense of them, and unless he is acquainted with the science of anatomy, knows nothing of them. Yet similar activities take place in the interiors of the human mind. Nothing can take place in the body except from the mind, for man's mind is his spirit, and his spirit is equally man; the sole difference being that what is done in the body is done naturally, while what is done in the mind is done spiritually; there is all similarity. Plainly, then, divine providence operates with every man in a thousand hidden ways, and its incessant care is to cleanse him, since its purpose is to save him. Plainly, too, nothing more is incumbent on man than to remove evils in the outward man; the Lord sees to the rest, when He is implored. 297. (iii) _The evil cannot be fully withdrawn from evil and led in good by the Lord so long as they believe their own intelligence to be everything and divine providence nothing._ It would seem that man could withdraw himself from evil provided he thought that this or that was contrary to the common good, or to what is useful, or to national or international law, and this an evil as well as a good man can do if by birth or through practice he is such that he can think clearly within himself, analysing and reasoning. But even then he is not capable of withdrawing himself from evil. The faculty of understanding and of perceiving, even abstractly, has indeed been given everyone by the Lord, to the evil as well as to the good, as has been shown above in many places, and yet man cannot deliver himself from evil by means of this faculty. For evil comes of the will, and the understanding influences the will only with light, enlightening and instructing. If the heat of the will, that is, man's love, is hot with the lust of evil, it is cold towards the affection of good, therefore does not receive the light but either repels or extinguishes it, or by some fabricated falsity turns it into evil. The light is then like winter light, which is as clear as the light in summer and remains as clear even when it flows into frozen trees. But this can be seen better in the following order: 1. When the will is in evil, one's own intelligence sees only falsity, and neither desires to see, nor can see, anything else. 2. If then one's own intelligence is confronted with truth, it either turns away from it or falsifies it. 3. Divine providence continually causes man to see truth, and also gives him affection for perceiving and receiving it. 4. Through this means man is withdrawn from evil, not by himself, but by the Lord. 298. For these things to be made apparent to the rational man, whether he is evil or good, thus whether he is in the light of winter or in the light of summer (for colors appear the same in them), they are to be explained in due order.
