"Seek not to know"
di John Dryden (1631-1700)

God of dreams:
Seek not to know what must not be reveal'd,
Joys only flow when hate is most conceal'd.
Too busy man would find his sorrows more
If future fortunes he should know before;
For by that knowledge of his destiny
He would not live at all but always die.
Enquire not then who shall from bonds be freed,
Who'tis shall wear a crown and who shall bleed.
All must submit to their appointed doom,
Fate and misfortune will too quickly come.
Let me no more with powerful charms be press'd
I am forbid by fate to tell the rest.
