“I developed The Great Teacher theory late in my freshman year. It was a cornerstone of the theory that great teachers had great personalities and that the greatest teachers had outrageous personalities. I did not like decorum or rectitude in a classroom; I preferred a highly oxygenated atmosphere, a climate of intemperance, rhetoric, and feverish melodrama. And I wanted my teachers to make me smart. A great teacher is my adversary, my conqueror, commissioned to chastise me. He leaves me tame and grateful for the new language he has purloined from other kings whose granaries are filled and whose libraries are famous. He tells me that teaching is the art of theft; knowing what to steal and from whom. Bad teachers do not touch me; the great ones never leave me. They ride with me during all my days, and I pass on to others what they have imparted to me. I exchange their handy gifts with strangers on trains, and I pretend the gifts are mine. I steal from the great teachers. And the truly wonderful thing about them is that they would applaud my theft, laugh at the thought of it, realizing that they had taught me their larcenous skills well.”

Context: I remember the morning that I first asked the meaning of the word, "love." This was before I knew many words. I had found a few early violets in the garden and brought them to my teacher. She tried to kiss me: but at that time I did not like to have any one kiss me except my mother. Miss Sullivan put her arm gently round me and spelled into my hand, "I love Helen."
"What is love?" I asked.
She drew me closer to her and said, "It is here," pointing to my heart, whose beats I was conscious of for the first time. Her words puzzled me very much because I did not then understand anything unless I touched it.
I smelt the violets in her hand and asked, half in words, half in signs, a question which meant, "Is love the sweetness of flowers?"
"No," said my teacher.
Again I thought. The warm sun was shining on us.
"Is this not love?" I asked, pointing in the direction from which the heat came. "Is this not love?"
It seemed to me that there could be nothing more beautiful than the sun, whose warmth makes all things grow. But Miss Sullivan shook her head, and I was greatly puzzled and disappointed. I thought it strange that my teacher could not show me love.
