That knowledge began its corrupting influence at once; it accumulated force as time went on. The irresistible pull of that knowledge has brought me to the point where I know not whether it is heredity, or the knowledge of it, which presses upon me—which has driven me like a slave. At times I feel certain that the last message of Judge Colfax, rather than the danger of which it intended to warn me, has been my menace.
At first I recalled the fact of my birth and inheritance with resentment and courage.
“I am myself,” I have exclaimed. “I alone am responsible for my life, my thoughts, my actions. They shall be according to my will to make them.”
Then the haunting doubt would oppose itself to my claim. It spoke to me like a person.
“No,” it said. “You are not yourself. You are the victim of fixed laws. The zebra is striped rather than spotted because its forebears wore stripes. So with you. You are half murderess and half gutter-snipe. You are woven according to the pattern. You are moulded according to the mould. You are a prisoner of heredity. Deceive yourself if you will for a time, but sooner or later you, like those from whom you came and of whom you are a part, will be the plaything of self-indulgence and weakness and passion. Fate has made your image that you see in the mirror, refined and comely so that you may see the better the work of heredity when it asserts itself.”
This voice was ever at my ear. It became a personal voice. I thought at first that it was the voice of some other being. At last I came by slow changes to the belief that it was not a voice outside of me. It was my Self that spoke. It was the heritage of evil within me. The thing that whispered to me with its condemning voice, frightening away my courage and sapping my strength of will, was my own blood!
I began to watch for the outcropping of evil in my conduct—for the moment when the force of heredity within me would make itself known to you and to the world. No morning dawned that I did not ask myself if night would fall without some opening of the gates of my character behind which so much that was evil, I believed, was clamoring to escape. I lived in two lives. In one I was your wife and the girl you had known, who now existed like an automaton, going senselessly through the acts of day to day existence. In the other I was a condemned victim, waiting in apprehension for the call of terrible and evil authority.
It was an accident which, at last, made real my fancies.
You remember that I was thrown from a horse. You remember that for days a torn nerve in my elbow gave me excruciating pain. You remember that, having regained my senses after the setting of the bone, I would not allow the doctor to give me any narcotic. You remember my protests against that form of relief.
I was afraid. I trembled not only with pain. I trembled with terror.
