You know, all is development. The principle is perpetually going on. First, there was nothing, then there was something; then-I forget the next-I think there were shells, then fishes; then we came-let me see-did we come next? Never mind that; we came at last. And at the next change there will be something very superior to us-something with wings. Ah! That's it: we were fishes, and I believe we shall be crows.
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.
