A bit of prose got stuck in my brain

That night I thought long and not without despair about what must become of me. I wanted very much to be a person of value and I had to ask myself how this could be possible if there were not something like a soul or like a spirit that is in the life of a person and which could endure any misfortune or disfigurement and yet be no less for it. If one were to be a person of value that value could not be a condition subject to the hazards of fortune. It had to be a quality that could not change. No matter what. Long before morning I knew that what I was seeking to discover was a thing I'd always known. That all courage was a form of constancy. That it was always himself that the coward abandoned first. After this all other betrayals came easily.
