D. ,. f WOOD- ALLEN PUBLISHING CO., Ann Arbor, Mich. 'A 24210 XJ :>ij**-«* kr Lact_23 lado Copyright, 19CX), by Dei^os F. Wii^cox. Entered at Stationer's Hall, I^ondon, Eng. This book is dedicated to the youths and maidens who do what they think they ought to do, admitting no ideal that is impracticable, and omitting no duty that is seen. PREFACE. THIS little book embodies a protest against the idea that the morals of marriage are a subject to be discussed by physicians alone, and as incidental to sexual pathology. *' Doctor books ' ' are kept in many households on a high and forbidden shelf. A good book on the phys- iology and ethics of the sex-life ought not to be out of place on the center-table or the mantel. But this book aims to be more than a protest. Its purpose is constructive — to point the way positively as well as negatively along which peo- ple may go to a life of greater happiness, keener intelligence, and truer responsibility. I have endeavored to keep free from purely visionary theories, and to limit myself in all essential points to what is strictly practicable. In questions of the morals of sex, as in all other ethical ques- tions, we should steer clear of the Scylla of the dreamer and the Charybdis of the man of the world. The former would impose upon us im- practicable ideals; the latter would persuade us that ideals are impracticable. Du^y can always be done, — not always easily, but always more easily when we set about it than when we leave it to set about us. This book, then, by throw- ing the relations of marriage open to discussion, attempts, as it were, to redeem a wide field of 5 6 PREFACE, human conduct to the domain of ethical princi- ples. Furthermore, in accordance with the spirit of the best thought of the time the ethical ideals urged here receive their highest sanction from the facts of social relations and social duties. There is much need that the youth of the world should recognize the social importance of sex- love and the structure and functions of the family. I am deeply indebted to the associations, an- tagonisms, and friendships of a body of earnest college men and women with whom for the first time in my experience discussion became free. There are many who have helped me directly and indirectly toward the realization of the thought of this book, — especially a brother who has from my youth urged me to ideal aims, a home-mate whose confidence and sympathy have made self-control and freedom of friendship easy, and a little daughter whose strong body and sturdy heart make me more than ever confident of the blessings regenerated marriage has in store for the children. I am under obligations to numerous friends for suggestions in regard to the manuscript, and particularly to Miss Flor- ence S. Webb for careful corrections and for help in the preparation of the notes. DKI.OS F. W11.COX. Elk Rapids, Mich,, May, igoo. CONTENTS Chap. Page. Introduction 9 I. THE SUPREME CO-OPERATION.
