Famous quotes containing the words drilling and/or mud:
“Don’t spend your time in drilling soldiers, who may turn out hirelings after all, but give to undrilled peasantry a country to fight for.”
—Henry David Thoreau (1817–1862)
“Earthly minds, like mud walls, resist the strongest batteries: and though, perhaps, sometimes the force of a clear argument may make some impression, yet they nevertheless stand firm, and keep out the enemy, truth, that would captivate or disturb them. Tell a man passionately in love, that he is jilted; bring a score of witnesses of the falsehood of his mistress, it is ten to one but three kind words of hers shall invalidate all their testimonies.”
—John Locke (1632–1704)
