Why are people so dumb?
They arent, it's just that when you grow up with a highly abstract language, that can express extremely difficult concepts, like for example the philosophical language used to explain the trinity, then you kinda lose the ability to see allegory or double meanings, you are used to taking both the concrete and the abstract literal.
Let me quote Aquinas to show you abstract thinking:
All the efforts of the human mind cannot exhaust the essence of a single fly.
Justice is a certain rectitude of mind whereby a man does what he ought to do in the circumstances confronting him.
Law is nothing other than a certain ordinance of reason for the common good, promulgated by the person who has the care of the community.
You take what he writes perfectly literal, now let me quote the Orphic Hymns:
Only-Begotten, noble race of Jove, blessed and fierce, who joy'st in caves to rove:
O, warlike Pallas, whose illustrious kind, ineffable and effable we find:
Magnanimous and fam'd, the rocky height, and groves, and shady mountains thee delight:
In arms rejoicing, who with Furies dire and wild, the souls of mortals dost inspire.
Gymnastic virgin of terrific mind, dire Gorgons bane, unmarried, blessed, kind:
Mother of arts, imperious; understood, rage to the wicked., wisdom to the good:
Female and male, the arts of war are thine, fanatic, much-form'd dragoness [Drakaina], divine:
O'er the Phlegrean giants rous'd to ire, thy coursers driving, with destruction dire.
Sprung from the head of Jove [Tritogeneia], of splendid mien, purger of evils, all-victorious queen.
Hear me, O Goddess, when to thee I pray, with supplicating voice both night and day,
And in my latest hour, peace and health, propitious times, and necessary wealth,
And, ever present, be thy vot'ries aid, O, much implor'd, art's parent, blue eyed maid.
Is this abstract, no, not unless the translator made a mistake, the descriptions are of the concrete, but you do not take them literal, it's an allegory, a mystical state of mind, that you see after you have gone over them countless times, it's not capable to understand these with the logical, abstract, literal reading of modern mind.
We have become to smart to see poetry and mysticism, so you get wackadoodles reading the Bible like some political manual or textbook.
