Famous quotes containing the word led:

    People are lucky and unlucky not according to what they get absolutely, but according to the ratio between what they get and what they have been led to expect.
    Samuel Butler (1835–1902)

    The greatest horrors in the history of mankind are not due to the ambition of the Napoleons or the vengeance of the Agamemnons, but to the doctrinaire philosophers. The theories of the sentimentalist Rousseau inspired the integrity of the passionless Robespierre. The cold-blooded calculations of Karl Marx led to the judicial and business-like operations of the Cheka.
    Aleister Crowley (1875–1947)

    In enterprise of martial kind,
    When there was any fighting,
    He led his regiment from behind—
    He found it less exciting.
    Sir William Schwenck Gilbert (1836–1911)
