His heart and hand both open and both free;

For what he has he gives, what thinks he shows;

Yet gives he not till judgment guide his bounty.

He hath a tear for pity, and a hand

Open as day for melting charity.

And smale foules maken melodie,

That slepen alle night with open eye,

So priketh hem nature in hir corages;

Than longen folk to gon on pilgrimages.

By the pricking of my thumbs,

Something wicked this way comes.

Open, locks,

Whoever knocks!

Together let us beat this ample field,

Try what the open, what the covert yield.

Alexander Pope (1688-1744): Essay on Man. Epistle i. Line 9.
