There can be no question that men and women are profoundly different; beyond the obvious physical differences, and the cultural differences, which are arguably added on late in the course of things like icing on a cake, there seem to be profound differences in the way the sexes relate to the world and to each other. It often seems that men and women are so different that we neither know the other's language; it is as if we were trying to function in a foreign land, while working with a bad translator.
