'To success? Oh! impossible!'
'To them who dare nothing is impossible. Rely upon me, and you may yet be happy. The time is come, Ambrosio, when regard for your comfort and tranquillity compels me to reveal a part of my History, with which you are still unacquainted. Listen, and do not interrupt me: Should my confession disgust you, remember that in making it my sole aim is to satisfy your wishes, and restore that peace to your heart which at present has abandoned it. I formerly mentioned that my Guardian was a Man of uncommon knowledge: He took pains to instil that knowledge into my infant mind. Among the various sciences which curiosity had induced him to explore, He neglected not that which by most is esteemed impious, and by many chimerical. I speak of those arts which relate to the world of Spirits. His deep researches into causes and effects, his unwearied application to the study of natural philosophy, his profound and unlimited knowledge of the properties and virtues of every gem which enriches the deep, of every herb which the earth produces, at length procured him the distinction which He had sought so long, so earnestly. His curiosity was fully slaked, his ambition amply gratified. He gave laws to the elements; He could reverse the order of nature; His eye read the mandates of futurity, and the infernal Spirits were submissive to his commands. Why shrink you from me? I understand that enquiring look. Your suspicions are right, though your terrors are unfounded. My Guardian concealed not from me his most precious acquisition. Yet had I never seen YOU, I should never have exerted my power. Like you I shuddered at the thoughts of Magic: Like you I had formed a terrible idea of the consequences of raising a daemon. To preserve that life which your love had taught me to prize, I had recourse to means which I trembled at employing. You remember that night which I past in St. Clare's Sepulchre? Then was it that, surrounded by mouldering bodies, I dared to perform those mystic rites which summoned to my aid a fallen Angel. Judge what must have been my joy at discovering that my terrors were imaginary: I saw the Daemon obedient to my orders, I saw him trembling at my frown, and found that, instead of selling my soul to a Master, my courage had purchased for myself a Slave.'
'Rash Matilda! What have you done? You have doomed yourself to endless perdition; You have bartered for momentary power eternal happiness! If on witchcraft depends the fruition of my desires, I renounce your aid most absolutely. The consequences are too horrible: I doat upon Antonia, but am not so blinded by lust as to sacrifice for her enjoyment my existence both in this world and the next.'
