Thus Nature gives us (let it check our pride)
The Virtue nearest to our Vice ally'd;
Reason the Byas turns to Good from Ill,
And Nero reigns a Titus, if he will.
The fiery soul abhorr'd in Catiline
In Decius charms, in Curtius is divine.
The same Ambition can destroy or save,
And makes a Patriot, as it makes a Knave.
