“Contemporary scientific discoveries (the neurosciences and neurobiology) confirm that there are biological differences between [men and women], and that it would be insane to deny their existence. Scientists do not deny that our relationship with the social and cultural environment has a determining influence (epi-genesis), but they have found some basic differences: the left hemisphere of the brain is more highly developed in women, who are actually less emotional than men but tend to be better at expressing their emotions because of their greater need to verbalize and communicate. Women have a more highly developed sense of hearing and touch, whereas men’s sight is more highly developed and means that they have a different relationship with visual spatial abilities. An analysis of hormonal functions shows that men and women relate differently to the environment and have different needs in terms of safety, no matter what culture they live in: women have a greater need for protection, and men a greater need for adventure. We are free to reject these scientific discoveries, or to regard them as irrelevant, but we have to admit that we must not confuse ‘equality’ with ‘identity’ in the sense of similarity.
