Selection from Arcana Coelestia ~ Emanuel Swedenborg
There are two states from which comes celestial light. The first is that into which man is introduced from infancy; for it is known that infants are in innocence and in the goods of love, which are the celestial things into which they are at first introduced by the Lord, and which are stored up in the child for use in later life, and for his use when he comes into the other life; these are what are called the first remains, spoken of in several places before.
The other state is, that man is introduced into spiritual and celestial things by means of knowledges, which must be implanted in the celestial things given from infancy.
(from Arcana Coelestia 1548)
Few, if any, know how man is brought to true wisdom. Intelligence is not wisdom, but leads to wisdom — for to understand what is true and good is not to be true and good, but to be wise is to be so.
Wisdom is predicated only of the life - that the man is such. A man is introduced to wisdom or to life by means of knowing [scire et nosse], that is, by means of knowledges [scientiae et cognitiones].
In every man there are two parts, the will and the understanding — the will is the primary part, the understanding is the secondary one. Man's life after death is according to his will part, not according to his intellectual part. The will is being formed in man by the Lord from infancy to childhood, which is effected by means of the innocence that is insinuated, and by means of charity toward parents, nurses, and little children of a like age; and by means of many other things that man knows nothing of, and which are celestial. Unless these celestial things were first insinuated into a man while an infant and a child, he could by no means become a man. Thus is formed the first plane.
But as a man is not a man unless he is endowed also with understanding, will alone does not make the man, but understanding together with will; and understanding cannot be acquired except by means of knowledges [scientiae et cognitiones] and therefore he must, from his childhood, be gradually imbued with these. Thus is formed the second plane.
When the intellectual part has been instructed in knowledges [scientiae et cognitiones], especially in the knowledges of truth and good, then first can the man be regenerated; and, when he is being regenerated, truths and goods are implanted by the Lord by means of knowledges in the celestial things with which he had been endowed by the Lord from infancy, so that his intellectual things make a one with his celestial things; and when the Lord has thus conjoined these, the man is endowed with charity, from which he begins to act, this charity being of conscience. In this way he for the first time receives new life, and this by degrees. The light of this life is called wisdom, which then takes the first place, and is set over the intelligence. Thus is formed the third plane.
When a man has become like this during his bodily life, he is then in the other life being continually perfected. These considerations show what is the light of intelligence, and what the light of wisdom.
