Shakespeare, 25th January

Heaven doth with us, as we with torches do;

Not light them for themselves: for if our virtues

Did not go forth of us, 'twere all alike

As if we had them not. Spirits are not finely touched

But to fine issues; nor Nature never lends

The smallest scruple of her excellence,

But, like a thrifty goddess, she determines

Herself the glory of a creditor.

               Measure for Measure, Act i., Sc. 1.
