My book is a statement of my faith in Woman as the predominant and responsible partner in the relations of the sexes. To such a belief my opinion was driven, as it were, not deliberately set from the beginning. The time when the resolve to write a book upon Woman first took a place in my thoughts goes back for many years. The child of a Puritan father, who died for the faith in which he believed, the desire to teach was born in my blood. Our character is forged in the past, we cannot escape our inheritance. I began my work as the head-mistress of a school for girls. I was young in experience and very ignorant of life. In my enthusiasm I was quite unconscious of my own limitations, I believed that I was able to train up a new type of free woman. Of course I failed. Looking back now I wonder if I ever taught my pupils one-hundredth part of what they taught me. Perhaps if any of them, separated from me by time and circumstances, chance to read my book, they may be glad to know that it was largely due to them and what I learnt from them that it has come to be written. Certainly it was in those days, when saddened by my own failures, that the purpose came to me, dimly but insistently, to seek out the Truth about Woman and the relations of the sexes. I began to read and to collect material at first for my own guidance and instruction, and as a necessary preparation for my work. I needed it: I must have been slow to learn. For a long time I wandered in the wrong path. My desire was to find proofs that would enable me to ignore all those facts of woman's organic constitution which makes her unlike man. I stumbled blindly into the fatal error of following masculine ideals. I desired freedom for women to enable them to live the same lives that men live and to do the same work that men do. I did not understand that this was a wastage of the force of womanhood; that no freedom can be of service to a woman unless it is a freedom to follow her own nature. I am very glad that the book that is now finished was not written in that period of my belief. I have waited and I have lived. Five years ago I took up definitely the task of writing the book. At that time the plan of the work was made and the first Introductory chapter written. Circumstances into which I need not enter caused the work again to be put aside. I am glad: I have learnt much in these last years. There is little more that I need to say. The book is divided into three parts--the first biological, the second historical. These two parts are preliminary to the third part, which deals with the present-day aspects of the Woman Problem, the differences between woman and man, and the relations of the sexes.
