{Footnote 1} Of the correspondence of the ear and of hearing (n. 4652-4660).  The ear corresponds to and therefore signifies perception and obedience (n. 2542, 3869, 4653, 5017, 7216, 8361, 9311, 9397, 10061).  The ear signifies the reception of truths (n. 5471, 5475, 9926).  The correspondence of the eye and its sight (n. 4403-4421, 4523-4534); from which the sight of the eye signifies the intelligence that belongs to faith, and also faith (n. 2701, 4410, 4526, 6923 9051, 10569).

272.  There is a still further reason, and this is in heaven the primary reason, why the angels are able to receive so great wisdom, namely, that they are without the love of self; for to the extent that any one is without the love of self he can become wise in Divine things.  It is that love that closes up the interiors against the Lord and heaven, and opens the exteriors and turns them toward itself; and in consequence all in whom that love rules are in thick darkness in respect to the things of heaven, however much light they may have in worldly matters.  The angels, on the other hand, are in the light of wisdom because they are without the love of self, for the heavenly loves in which they are, which are love to the Lord and love towards the neighbor, open the interiors, because these loves are from the Lord and the Lord Himself is in them. (That these loves constitute heaven in general, and form heaven in each one in particular, may be seen above, n. 13-19).  As heavenly loves open the interiors to the Lord so all angels turn their faces towards the Lord (n. 142); because in the spiritual world the love turns the interiors of everyone to itself, and whichever way it turns the interiors it also turns the face, since the face there makes one with the interiors, for it is their outward form.  Because the love turns the interiors and the face to itself, it also conjoins itself to them (love being spiritual conjunction), and shares its own with them.  From that turning and consequent conjunction and sharing the angels have their wisdom.  That all conjunction and all turning in the spiritual world are in accord may be seen above (n. 255).

273.  Although the angels are continually perfected in wisdom,{1} their wisdom, even to eternity, cannot become so perfect that there can be any ratio between it and the Lord’s Divine wisdom; for the Lord’s Divine wisdom is infinite and the wisdom of angels finite; and between what is Infinite and what is finite no ratio is possible.

  {Footnote 1} Angels are perfected to eternity (n. 4803, 6648).

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.
