So may the outward shows be least themselves: The world is still deceived with ornament. In law, what plea so tainted and corrupt, But, being seasoned with a gracious voice, Obscures the show of evil?

For he has proved that for his part he will do anything for anybody with a view to virtue and improvement, than which there can be nothing nobler.
