[7] Ellen Key, The Renaissance of Motherhood, p. 27: “Because of her motherhood, woman’s sexual nature gradually became purer than man’s. The child became more and more the centre of her thoughts and her deeds. Thus the strength of her erotic instincts diminished. The tenderness awakened in her by her children also benefited the father. Out of this tenderness—as also out of the admiration for the manly qualities which the father developed in the defence of herself and her children—gradually arose the erotic feeling directed to this man alone. Thus love began.”

“This is a Theban law most just and humane: that no Theban might expose his child or leave it in a wilderness, upon pain of death. But if the father were extremely poor, whether it were male or female, the law requires that as soon as it is born it be brought in the swaddling clouts to the magistrate, who, receiving it, delivers it to some other for some small reward, conditioning with him that he shall bring up the child, and when it is grown up take it into his service, man or maid, and have the benefit of its labour in requital for its education.”
