I think it was "librarian." It might have been "hunter." These were not words but coordinates, complex signs with a meaning of identity, location and time. Names that denote, sense and reference in perfect alignment—conjunction, in fact, understood in a way I never have before. Has Z put itself in my head so that this conversation will make sense to me? Am I thinking as myself, or using its mind? And if so, how will that affect my choice?
