274. As it is wisdom that makes the angels perfect and constitutes their life, and as heaven with its goods flows into everyone in accordance with his wisdom, so all in heaven desire and hunger for wisdom much as a hungry man hungers for food. So, too, knowledge, intelligence, and wisdom are spiritual nutriment, as food is natural nutriment; and the one corresponds to the other. 275. The angels in the same heaven, or in the same society of heaven, are not all in like wisdom; their wisdom differs. Those at the center are in the greatest wisdom, and those round about even to the borders are in less wisdom. The decrease of wisdom in accord with the distance from the center is like the decrease of light verging to shade (see n. 43 and 128). Their light is in the same degree as their wisdom, since the light of heaven is the Divine wisdom, and everyone is in light in the measure of his reception of wisdom. Respecting the light of heaven and the varying kinds of reception of it see above (n. 126-132). 276. XXXI. THE STATE OF INNOCENCE OF ANGELS IN HEAVEN. What innocence is and its nature few in the world know, and those who are in evil know nothing about it. It is, indeed, visible to the eyes, as seen in the face, speech and movements, particularly of children; and yet what innocence is, and especially that it is that in which heaven is stored up in man is unknown. In making this known let us proceed in order, and consider first the innocence of childhood, then the innocence of wisdom, and lastly the state of heaven in regard to innocence.
