Sweet are the uses of adversity,

Which like the toad, ugly and venomous,

Wears yet a precious jewel in his head;

And this our life, exempt from public haunt,

Finds tongues in trees, books in the running brooks,

Sermons in stones, and good in every thing.

William Shakespeare (1564-1616): As You Like It. Act ii. Sc. 1.

O, I have passed a miserable night,

So full of ugly sights, of ghastly dreams,

That, as I am a Christian faithful man,

I would not spend another such a night,

Though 't were to buy a world of happy days.

William Shakespeare (1564-1616): King Richard III. Act i. Sc. 4.
