My dear lady, you have put my whole case against romance into a few sentences. That is just why I turned my back on the romantic man with the artist nature, as he called his infatuation. I thanked him for teaching me to use my eyes and ears; but I told him that his beauty worshipping and happiness hunting and woman idealizing was not worth a dump as a philosophy of life; so he called me Philistine and went his way. (ANA: It seems that Woman taught you something, too, with all her defects.) She did more: she interpreted all the other teaching for me. Ah, my friends, when the barriers were down for the first time, what an astounding illumination! I had been prepared for infatuation, for intoxication, for all the illusions of love's young dream; and lo! never was my perception clearer, nor my criticism more ruthless. The most jealous rival of my mistress never saw every blemish in her more keenly than I. I was not duped: I took her without chloroform. (ANA: But you did take her.) That was the revelation. Up to that moment I had never lost the sense of being my own master; never consciously taken a single step until my reason had examined and approved it. I had come to believe that I was a purely rational creature: a thinker! I said, with the foolish philosopher, "I think; therefore I am." It was Woman who taught me to say "I am; therefore I think." And also "I would think more; therefore I must be more."
