"I have no way, and therefore want no eyes;
I stumbled when I saw. Full oft ’tis seen,
Our means secure us and our mere defects
Prove our commodities. O dear son Edgar,
The food of thy abusèd father’s wrath,
Might I but live to see thee in my touch,
I’d say I had eyes again!"
Shakespeare's King Lear
"Ideas won't keep; something must be done about them."
