Earthman's Viewpoint
For years I've tried to understand and to conform to the ethics and ideas of all the people who have come through this station. I've pushed my own human instincts and training to one side. I've tried to understand other viewpoints and to evaluate other ways of thinking, many of which did violence to my own. I am glad of all of it, for it has given me a chance to go beyond the narrowness of Earth. I think I gained something from it all. But none of this touched Earth; only myself was involved. This business touches Earth and I must approach it from an Earthman's viewpoint. In this particular instance I am not simply the keeper of a galactic station.
Not in a duel yet
