“Oh, if in this man, whose eyes can flash Heaven's lightning, and make all Calibans into a cramp, there dwelt not, as the essence of his very being, a God's justice, human Nobleness, Veracity and Mercy,—I should tremble for the world. But his strength, let us rejoice to understand, is even this: The quantity of Justice, of Valour and Pity that is in him. To hypocrites and tailored quacks in high places, his eyes are lightning; but they melt in dewy pity softer than a mother's to the downpressed, maltreated; in his heart, in his great thought, is a sanctuary for all the wretched.”

1840s, Past and Present (1843)
Context: Thou, O World, how wilt thou secure thyself against this man? Thou canst not hire him by thy guineas; nor by thy gibbets and law-penalties restrain him. He eludes thee like a Spirit. Thou canst not forward him, thou canst not hinder him. Thy penalties, thy poverties, neglects, contumelies: behold, all these are good for him. Come to him as an enemy; turn from him as an unfriend; only do not this one thing,—infect him not with thy own delusion: the benign Genius, were it by very death, shall guard him against this!—What wilt thou do with him? He is above thee, like a god. Thou, in thy stupendous three-inch pattens, art under him. He is thy born king, thy conqueror and supreme lawgiver: not all the guineas and cannons, and leather and prunella, under the sky can save thee from him. Hardest thickskinned Mammon-world, ruggedest Caliban shall obey him, or become not Caliban but a cramp. Oh, if in this man, whose eyes can flash Heaven's lightning, and make all Calibans into a cramp, there dwelt not, as the essence of his very being, a God's justice, human Nobleness, Veracity and Mercy,—I should tremble for the world. But his strength, let us rejoice to understand, is even this: The quantity of Justice, of Valour and Pity that is in him. To hypocrites and tailored quacks in high places, his eyes are lightning; but they melt in dewy pity softer than a mother's to the downpressed, maltreated; in his heart, in his great thought, is a sanctuary for all the wretched.
