And so I became a surgeon.

Thirty years later, I am not known for speed, or daring, or technical genius. Call me steady, call me plodding; say I adopt the style and technique that suits the patient and the particular situation and I'll consider that high praise. I take heart from my fellow physicians who come to me when they themselves must suffer the knife. They know that Marion Stone will be as involved after the surgery as before and during. They know I have no use for surgical aphorisms such as “When in doubt, cut it out” or “Why wait when you can operate” other than for how reliably they reveal the shallowest intellects in our field. My father, for whose skills as a surgeon I have the deepest respect, says, “The operation with the best outcome is the one you decide not to do.” Knowing when not to operate, knowing when I am in over my head, knowing when to call for the assistance of a surgeon of my father's caliber—that kind of talent, that kind of “brilliance,” goes unheralded.

On one occasion with a patient in grave peril, I begged my father to operate. He stood silent at the bedside, his fingers lingering on the patient's pulse long after he had registered the heart rate, as if he needed the touch of skin, the thready signal in the radial artery to catalyze his decision. In his taut expression I saw complete concentration. I imagined I could see the cogs turning in his head; I imagined I saw the shimmer of tears in his eyes. With utmost care he weighed one option against another. At last, he shook his head, and turned away.

I followed. “Dr. Stone,” I said, using his title though I longed to cry out, Father! “An operation is his only chance,” I said. In my heart I knew the chance was infinitesimally small, and the first whiff of anesthesia might end it all. My father put his hand on my shoulder. He spoke to me gently, as if to a junior colleague rather than his son. “Marion, remember the Eleventh Commandment,” he said. “Thou shall not operate on the day of a patient's death.”
