“For the want of a nail the shoe was lost,
For the want of a shoe the horse was lost,
For the want of a horse the rider was lost,
For the want of a rider the battle was lost,
For the want of a battle the kingdom was lost,
And all for the want of a horseshoe-nail.”
― Benjamin Franklin

― Alfred Korzybski, Manhood of Humanity: The Science and Art of Human Engineering

“And thus I clothe my naked villainy
With odd old ends stol'n out of holy writ;
And seem a saint, when most I play the devil.”
― William Shakespeare, Richard III

“Everything has its limit - iron ore cannot be educated into gold.”
― Mark Twain
