Man Made

A story that comes to grips with an age-old question—what is soul? and where?—and postulates an age-new answer.
If I listed every trouble I've accumulated in a mere two hundred odd years you might be inclined to laugh. When a tale of woe piles up too many details it looks ridiculous, unreal. So here, at the outset, I want to say my life has not been a tragic one—whose life is in this day of advanced techniques and universal good will?—but that, on the contrary, I have enjoyed this Earth and Solar System and all the abundant interests that it has offered me. If, lying here beneath these great lights, I could only be as sure of joy in the future....
My name is Treb Hawley. As far back as I can remember in my childhood, I was always interested in astronautics. From the age of ten I specialized in that subject, never for a moment regretting the choice. When I was still a child of twenty-four I took part in the Ninth Jupiter Expedition and after that there were many more. I had a precocious marriage at thirty and my boys, Robert and Neil, were born within a few years after Marla and I wed. It was fortunate that I fought for government permission that early; after the accident, despite my high rating, I would have been denied the rare privilege of parenthood.
That accident, the first one, took place when I was fifty. On Planet 12 of the Centauri System I was attacked by a six-limbed primate and was badly mangled on the left side before breaking loose to destroy it. Surgical Corps operated within an hour. Although they did an excellent prosthetic job after removing my left leg and arm, the substituted limbs had their limitations. While they permitted me to do all my jobs, phantom pain was a constant problem. There were new methods of prosthesis to eliminate this weird effect but these were only available back on the home planets.
I had to wait one year for this release. Meanwhile I had plenty of time to contemplate my mysterious affliction; the mystery of it was so great that I had little chance to notice how painful it actually was. There is enough strangeness in feeling with absolute certainty that a limb exists where actually there is nothing, but the strangeness is compounded when you look down and discover that not only is the leg gone but that another, mechanical one has taken its place. Dr. Erics, who had performed the operation, said this difficulty would ultimately prove a blessing but I often had my doubts.
