O, who can hold a fire in his hand

By thinking on the frosty Caucasus?

Or cloy the hungry edge of appetite

By bare imagination of a feast?

Or wallow naked in December snow

By thinking on fantastic summer's heat?

O, no! the apprehension of the good

Gives but the greater feeling to the worse.

William Shakespeare (1564-1616): King Richard II. Act i. Sc. 3.

No, 't is slander,

Whose edge is sharper than the sword, whose tongue

Outvenoms all the worms of Nile, whose breath

Rides on the posting winds, and doth belie

All corners of the world.

William Shakespeare (1564-1616): Cymbeline. Act iii. Sc. 4.

O, who can hold a fire in his hand

By thinking on the frosty Caucasus?

Or cloy the hungry edge of appetite

By bare imagination of a feast?

Or wallow naked in December snow

By thinking on fantastic summer's heat?

O, no! the apprehension of the good

Gives but the greater feeling to the worse.

William Shakespeare (1564-1616): King Richard II. Act i. Sc. 3.

Heard so oft

In worst extremes, and on the perilous edge

Of battle.

John Milton (1608-1674): Paradise Lost. Book i. Line 275.

Neither a borrower nor a lender be;

For loan oft loses both itself and friend,

And borrowing dulls the edge of husbandry.

This above all: to thine own self be true,

And it must follow, as the night the day,

Thou canst not then be false to any man.

William Shakespeare (1564-1616): Hamlet. Act i. Sc. 3.

There is no jesting with edge tools.

Beaumont And Fletcher: The Little French Lawyer. Act iv. Sc. 7.
