I repeat... that all power is a trust; that we are accountable for its exercise; that from the people and for the people all springs, and all must exist.
Benjamin DisraeliNo government can be long secure without a formidable opposition. It reduces their supporters to that tractable number which can be managed by the joint influences of fruition and hope. It offers vengeance to the discontented, and distinction to the ambitious; and employs the energies of aspiring spirits, who otherwise may prove traitors in a division or assassins in a debate.
