HENRY: God almighty,
There is some soul of goodness in things evil,
Would men observingly distill it out.
For our bad neighbor makes us early stirrers,
Which is both healthful and good husbandry.
Besides, they are our outward consciences
And preachers to us all, admonishing
That we should dress us fairly for our end.
Thus may we gather honey from the weed
And make a moral of the devil himself.

William Shakespeare (1564-1616) English dramatist and poet

Henry V, Act 4, sc. 1, l. 3ff (4.1.3-12) (1599)
