Only two sexes. I was disappointed. If human bodies, minds, fates are so complex, if we are free like no other mammal, why limit the range? I seethed, and then, like everyone else, I settled down and made the best of my inheritance. For sure, complexity would come upon me in time. Until then, my plan was to arrive as a freeborn Englishman, a creature of the post English-as-well-as-Scottish-and-French Enlightenment.
