“O me, what eyes hath Love put in my head,Which have no correspondence with true sight!...Or, if they have, where is my judgment fled,That censures falsely what they see aright?If that be fair whereon my false eyes dote,What means the world to say it is not so?If it be not, then love doth well denoteLove's eye is not so true as all men's 'No.'How can it? O, how can Love's eye be true,That is so vex'd with watching and with tears? No marvel then, though I mistake my view;The sun itself sees not till heaven clears.O cunning Love! with tears thou keep'st me blind,Lest eyes well-seeing thy foul faults should find. - Shakespeare's Sonnet 148”

“And Caesar's spirit, raging for revenge,With Ate by his side come hot from hell,Shall in these confines with a monarch's voice Cry "Havoc!" and let slip the dogs of war,That this foul deed shall smell above the earthWith carrion men, groaning for burial.”

“Foul words is but foul wind, and foul wind is but foul breath, and foul breath is noisome; therefore I will depart unkissed.”

“If one good deed in all my life I did, I do repent it from my very soul.”
