[10] Knowledge [scientifica] with the evil are falsities, because they are adapted to evils, but with the good the same knowledges are truths, because applied to what is good (n. 6917).

     True knowledges [scientifica] with the evil are not true,
     however much they may appear to be true when uttered,
     because there is evil within them (n. 10331).

[11] An example of the desire to know [sciendi], which spirits have (n. 1974).  Angels have an illimitable longing to know [sciendi] and to become wise, since learning [scientia], intelligence, and wisdom are spiritual food (n. 3114, 4459, 4792, 4976, 5147, 5293, 5340, 5342, 5410, 5426, 5576, 5582, 5588, 5655, 6277, 8562, 9003).

The knowledge [scientia] of the ancients was the knowledge [scientia] of correspondences and representations, by which they gained entrance into the knowledge [cognitionem] of spiritual things; but that knowledge [scientia] at this day is wholly lost (n. 4749, 4844, 4964, 4965).

[12] For spiritual truths to be comprehended the following universals must be known [scientur]. (i) All things in the universe have relation to good and truth and to their conjunction that they may be anything, thus to love and faith and their conjunction. (ii) Man has understanding and will; and the understanding is the receptacle of truth and the will of good; and all things in man have relation to these two and to their conjunction, as all things have relation to truth and good and their conjunction. (iii) There is an internal man and an external man, which are as distinct from each other as heaven and the world are, and yet for a man to be truly a man, these must make one. (iv) The internal man is in the light of heaven, and the external man is in the light of the world; and the light of heaven is Divine truth itself, from which is all intelligence. (v) Between the things in the internal man and those in the external there is a correspondence, therefore the different aspect they present is such that they can be distinguished only by means of a knowledge [scientiam] of correspondences.  Unless these and many other things are known [scientur], nothing but incongruous ideas of spiritual and heavenly truths can be conceived and formed; therefore without these universals the knowledges [scientifica et cognitiones] of the natural man can be of but little service to the rational man for understanding and growth.  This makes clear how necessary knowledges [scientifica] are.
