            "To entertain these fair well-spoken days," + 
            "I am determined to prove a villain" + 
            "And hate the idle pleasures of these days." + 
            "Plots have I laid, inductions dangerous," + 
            "By drunken prophecies, libels and dreams," +

            "About a prophecy, which says that 'G'" + 
            "Of Edward's heirs the murderer shall be." + 
            "Dive, thoughts, down to my soul: here" + 
            "Clarence comes.",
            
            "To bait fish withal: if it will feed nothing else," + 
            "it will feed my revenge. He hath disgraced me, and" + 
            "hindered me half a million; laughed at my losses," + 
            "mocked at my gains, scorned my nation, thwarted my" + 
            "bargains, cooled my friends, heated mine" + 
            "enemies; and what's his reason? I am a Jew. Hath" + 
            "not a Jew eyes? hath not a Jew hands, organs," + 
            "dimensions, senses, affections, passions? fed with" + 
            "the same food, hurt with the same weapons, subject" + 
            "to the same diseases, healed by the same means," + 
            "warmed and cooled by the same winter and summer, as" + 
            "a Christian is? If you prick us, do we not bleed?" + 
            "if you tickle us, do we not laugh? if you poison" + 
            "us, do we not die? and if you wrong us, shall we not" + 
            "revenge? If we are like you in the rest, we will" + 
            "resemble you in that. If a Jew wrong a Christian," + 
            "what is his humility? Revenge. If a Christian" + 
            "wrong a Jew, what should his sufferance be by" + 
            "Christian example? Why, revenge. The villany you" + 
            "teach me, I will execute, and it shall go hard but I" + 
            "will better the instruction.",
            
            "Virtue! a fig! 'tis in ourselves that we are thus" + 
            "or thus. Our bodies are our gardens, to the which" + 
            "our wills are gardeners: so that if we will plant" + 
            "nettles, or sow lettuce, set hyssop and weed up" + 
            "thyme, supply it with one gender of herbs, or" + 
            "distract it with many, either to have it sterile" + 
            "with idleness, or manured with industry, why, the" + 
            "power and corrigible authority of this lies in our" + 
            "wills. If the balance of our lives had not one" + 
            "scale of reason to poise another of sensuality, the" + 
            "blood and baseness of our natures would conduct us" + 
            "to most preposterous conclusions: but we have" + 
            "reason to cool our raging motions, our carnal" + 
            "stings, our unbitted lusts, whereof I take this that" + 
            "you call love to be a sect or scion.",

            "Blow, winds, and crack your cheeks! rage! blow!" + 
            "You cataracts and hurricanoes, spout" + 
            "Till you have drench'd our steeples, drown'd the cocks!" + 
            "You sulphurous and thought-executing fires," + 
            "Vaunt-couriers to oak-cleaving thunderbolts," + 
            "Singe my white head! And thou, all-shaking thunder," + 
            "Smite flat the thick rotundity o' the world!" + 
            "Crack nature's moulds, an germens spill at once," + 
            "That make ingrateful man!"
