The origin of these Studies dates from many years back. As a youth I was faced, as others are, by the problem of sex. Living partly in an Australian city where the ways of life were plainly seen, partly in the solitude of the bush, I was free both to contemplate and to meditate many things. A resolve slowly grew up within me: one main part of my life-work should be to make clear the problems of sex.

That was more than twenty years ago. Since then I can honestly say that in all that I have done that resolve has never been very far from my thoughts. I have always been slowly working up to this central problem; and in a book published some three years ago—Man and Woman: a Study of Human Secondary Sexual Characters—I put forward what was, in my own eyes, an introduction to the study of the primary questions of sexual psychology.

Now that I have at length reached the time for beginning to publish my results, these results scarcely seem to me large. As a youth, I had hoped to settle problems for those who came after; now I am quietly content if I do little more than state them. For even that, I now think, is much; it is at least the half of knowledge. In this particular field the evil of ignorance is magnified by our efforts to suppress that which never can be suppressed, though in the effort of suppression it may become perverted. I have at least tried to find out what are the facts, among normal people as well as among abnormal people; for, while it seems to me that the physician's training is necessary in order to ascertain the facts, the physician for the most part only obtains the abnormal facts, which alone bring little light. I have tried to get at the facts, and, having got at the facts, to look them simply and squarely in the face. If I cannot perhaps turn the lock myself, I bring the key which can alone in the end rightly open the door: the key of sincerity. That is my one panacea: sincerity.

I know that many of my friends, people on whose side I, too, am to be found, retort with another word: reticence. It is a mistake, they say, to try to uncover these things; leave the sexual instincts alone, to grow up and develop in the shy solitude they love, and they will be sure to grow up and develop wholesomely. But, as a matter of fact, that is precisely what we can not and will not ever allow them to do. There are very few middle-aged men and women who can clearly recall the facts of their lives and tell you in all honesty that their sexual instincts have developed easily and wholesomely throughout. And it should not be difficult to see why this is so. Let my friends try to transfer their feelings and theories from the reproductive region to, let us say, the nutritive region, the only other which can be compared to it for importance. Suppose that eating and drinking was never spoken of openly, save in veiled or poetic language, and that no one ever ate food publicly, because it was considered immoral and immodest to reveal the mysteries of this natural function. We know what would occur. A considerable proportion of the community, more especially the more youthful members, possessed by an instinctive and legitimate curiosity, would concentrate their thoughts on the subject. They would have so many problems to puzzle over: How often ought I to eat? What ought I to eat? Is it wrong to eat fruit, which I like? Ought I to eat grass, which I don't like? Instinct notwithstanding, we may be quite sure that only a small minority would succeed in eating reasonably and wholesomely. The sexual secrecy of life is even more disastrous than such a nutritive secrecy would be; partly because we expend such a wealth of moral energy in directing or misdirecting it, partly because the sexual impulse normally develops at the same time as the intellectual impulse, not in the early years of life, when wholesome instinctive habits might be formed. And there is always some ignorant and foolish friend who is prepared still further to muddle things: Eat a meal every other day! Eat twelve meals a day! Never eat fruit! Always eat grass! The advice emphatically given in sexual matters is usually not less absurd than this. When, however, the matter is fully open, the problems of food are not indeed wholly solved, but everyone is enabled by the experience of his fellows to reach some sort of situation suited to his own case. And when the rigid secrecy is once swept away a sane and natural reticence becomes for the first time possible.
