mind is like soil which is such as it is made by cultivation. {Footnote 1} Most beautiful colors are seen in heaven (n. 1053, 1624). Colors in heaven are from the light there, and are modifications or variegations of that light (n. 1042, 1043, 1053, 1624, 3993, 4530, 4742, 4922). Thus they are manifestations of truth from good, and they signify such things as pertain to intelligence and wisdom (n. 4530, 4677, 4922, 9466). EXTRACTS FROM THE ARCANA COELESTIA RESPECTING KNOWLEDGES. [In these extracts scientia, scientificum and cognitio are alike rendered knowledge, because any distinction between them intended by the author is not sufficiently obvious to be uniformly indicated in English. -- Tr.] Man ought to be fully instructed in knowledges [scientiis et cognitionibus], since by means of them he learns to think [cogitare], afterwards to understand what is true and good, and finally to be wise (n. 129, 1450, 1451, 1453, 1548, 1802). Knowledges [scientifica] are the first things on which the life of man, civil, moral, and spiritual, is built and founded, and they are to be learned for the sake of use as an end (n. 1489, 3310). Knowledges [cognitiones] open the way to the internal man, and afterwards conjoin that man with the external in accordance with uses (n. 1563, 1616). The rational faculty has its birth by means of knowledges [scientias et cognitiones] (n. 1895, 1900, 3086). But not by means of knowledges [cognitiones] themselves, but by means of affection for the uses derived from them (n. 1895). [2] There are knowledges [scientifica] that give entrance to Divine truths, and knowledges [scientifica] that do not (n. 5213). Empty knowledges [scientifica] are to be destroyed (n. 1489, 1492, 1499, 1581). Empty knowledges [scientifica] are such as have the loves of self and of the world as an end, and sustain those loves, and withdraw from love to God and love towards the neighbor, because such knowledges close up the internal man, even to the extent that man becomes unable to receive any thing from heaven (n. 1563, 1600). Knowledges [scientifica] are means to becoming wise and means to becoming insane and by them the internal man is either opened or closed, and thus the rational is either enriched or destroyed (n. 4156, 8628, 9922). [3] The internal man is opened and gradually perfected by means of knowledges [scientifica] if man has good use as an end, especially use that looks to external life (n. 3086). Then knowledges [scientificis], which are in the natural man, are met by spiritual and heavenly things from the spiritual man, and these adopt such of them as are suitable (n. 1495).
