Keep your own secret, and get out other people's. Keep your own temper, and artfully warm other people's. Counterwork your rivalswith diligence and dexterity, but at the same time with the utmost personal civility to them: and be firm without heat.
Lord Philip Dormer Stanhope Chesterfield, Philip Dormer Stanhope Earl of Chesterfield (1855). “The Works of Lord Chesterfield: Including His Letters to His Son, Etc : to which is Prefixed, an Original Life of the Author”, p.483
