to clouds which come between [the earth and] the sun.  They were led into this idea concerning the sciences by the conduct of some who had come from our Earth, who boasted in their presence that they were wise by reason of the sciences.  The spirits from our Earth, who thus boasted, were such as placed wisdom in such things as are matters of the memory only, as in languages, especially the Hebrew, Greek, and Latin, in the noteworthy publications of the learned world, in criticism, in bare experimental facts, and in terms, especially philosophical ones, and other similar things, not using them as means for becoming wise, but making wisdom to consist in those very things.  Such persons, in consequence of not having cultivated their rational faculty by the sciences as means, in the other life have little perception, for they see only in terms and from terms, and, for those who see in this way, those things are as little formless masses, and as clouds before the intellectual sight (see above, no. 38); and those who have been conceited of their learning from this source perceive still less.  But those who have used the sciences as means of invalidating and annihilating the things that belong to the church and to faith, have entirely destroyed their Intellectual, and see in the dark like owls, seeing falsity for truth and evil for good.  The spirits of Jupiter, from intercourse with such persons, concluded that the sciences occasion shade and blindness; it was told them, however, that on this Earth the sciences are means of opening the intellectual sight, which is in the light of heaven; but because of the dominion of such things as belong to merely natural and sensual life, the sciences, to those [who are such], are means of becoming insane, that is to say, of confirming themselves in favour of Nature against the Divine, and in favour of the world against heaven.  The sciences, they were further informed, are in themselves spiritual riches, and those who possess them are like those who possess worldly riches, which likewise are means of performing uses to oneself, one’s neighbour, and one’s country, and are also means of doing evil to them.  They are, moreover, like dress, which serves for use and adornment and also for gratifying pride, as with those who would be held in honour for that alone.  The spirits of the earth Jupiter understood this perfectly; but they were surprised that, being men, they should stand still in the means, and prefer to wisdom itself such things as only lead to it; and that they did not see, that to immerse the mind in these, and not raise it above them, is to becloud and blind it.
