I think the belief that ignorance poses the greatest threat to society (and to individuals as members of society) is at the back of it.
Remember that famous scene in Stave III of Dickens’ A Christmas Carol, when the Ghost of Christmas Present shows Scrooge two wretched children crouching beneath his robe?
=====[EXCERPT BEGINS]
From the foldings of its robe, it brought two children; wretched, abject, frightful, hideous, miserable. They knelt down at its feet, and clung upon the outside of its garment.
“Oh, Man! look here. Look, look, down here!” exclaimed the Ghost.
They were a boy and girl. Yellow, meagre, ragged, scowling, wolfish; but prostrate, too, in their humility. Where graceful youth should have filled their features out, and touched them with its freshest tints, a stale and shrivelled hand, like that of age, had pinched, and twisted them, and pulled them into shreds. Where angels might have sat enthroned, devils lurked, and glared out menacing. No change, no degradation, no perversion of humanity, in any grade, through all the mysteries of wonderful creation, has monsters half so horrible and dread.
Scrooge started back, appalled. Having them shown to him in this way, he tried to say they were fine children, but the words choked themselves, rather than be parties to a lie of such enormous magnitude.
“Spirit! are they yours?” Scrooge could say no more.
“They are Man’s,” said the Spirit, looking down upon them. “And they cling to me, appealing from their fathers. This boy is Ignorance. This girl is Want. Beware them both, and all of their degree, but most of all beware this boy, for on his brow I see that written which is Doom, unless the writing be erased. Deny it!”
=====[EXCERPT ENDS]
The message that ignorance and want (poverty) are the greatest dangers, and ignorance the greater of the two, is emphatically clear.
Unfortunately at some point the goal of public education went from remedying ignorance to grinding out good little citizens to feed the machinery of the workplace. There is, as well, a cultural component that is not altogether benign.
I still believe firmly in public education, but, I’m afraid, more as an ideal than as an observed practice. Part of my slightly cynical view stems, no doubt, from awareness of the very ignorant rejection of education by certain segments of society. Contrast this with the hunger for education that we see in cultures where it is not provided or is offered to only a few.
The glorification of ignorance is an obscenity.
