Taste, when once obtained, may be said to be no acquiring faculty, and must remain stationary; but knowledge is of perpetual growth and has infinite demands. Taste, like an artificial canal, winds through a beautiful country, but its borders are confined and its term is limited. Knowledge navigates the ocean, and is perpetually on voyages of discovery.
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.
