Thyself and thy belongings
Are not thine own so proper as to waste
Thyself upon thy virtues, they on thee.
Heaven doth with us as we with torches do,
Not light them for themselves; for if our virtues
Did not go forth of us, 't were all alike
As if we had them not. Spirits are not finely touch'd
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,
Both thanks and use.
-- William Shakespeare (1564-1616), Measure for Measure
-- Act i, Sc. 1
