A poem from the 19th century about idiots that I think is an example of the charity-tragedy model of disability

"
A mental blindness seals his eye
To this fair earth of ours;
He sees no brightness in the sun
No beauty in the flowers.

Sweet sounds that gladden other hearts
He seemeth not to hear,
The melodies of singing birds
Touch not his untuned ear.

Yet not upon him may we gaze
With cold despairing eye,
'Tis not decreed the idiot born
Must a poor idiot die.

Yes, 'tis a blessed charity
The fetters to unbind,
That hold the dull imprison'd soul,
The dark and hidden mind.

And God will surely give to those
His blessing and His love,
Who rightly use their better gifts
Affliction to remove.
"

It's in the last line where there's the tragedy. There's a model of
disability where blindness isn't something that should be taken away. In
that model society is made for blind people because blind people are
part of society and the diversity of the human race in an advanced
civilisation. If electronic engineers ever invent a replacement eyeball
it wouldn't be used. If genetics means no babies will be born who are
blind that science is never used. Society is adapted to the blind
instead, as it should be.
