There is no talent so useful toward rising in the world, or which puts men more out of the reach of fortune, than that quality generally possessed by the dullest sort of men, and in common speech called discretion; a species of lower prudence, by the assistance of which, people of the meanest intellectuals, without any other qualification, pass through the world in great tranquillity, and with universal good treatment, neither giving nor taking offence.
Jonathan Swift
