I can only conjecture that Jones agrees with the middle and upper classes in associating sex with sin. I have never tried to think out my reasons for believing in co-education; possibly the true reason is that having grown up in a co-education atmosphere, co-education has become a part of me just as my Scots accent has. In other words, I may have a co-education complex. If that is so, my arguments will be mere rationalisations, but I give them for what they are worth. We are all born with a strong sex instinct, and this instinct must find expression in some way. We know that the sex energy can be sublimated, that is, raised to a higher power. For instance, the creative sex urge may be directed to the making of a bookcase, or the making of a century at cricket. But I know of no evidence to prove that all the instinct can be sublimated. An adolescent may spend his days at craftwork and games, but he will have erotic dreams at nights. All the drawing and painting in the world will not prevent his having emotion when he looks at the face of a pretty girl. In our segregation schools boys and girls see nothing of each other. The unsublimated sex instinct finds expression in homosexuality, that is the emotion that should go to the opposite sex is fixed on a person of the same sex. I admit that we are all more or less homosexual; otherwise there could be no friendship between man and man, or woman and woman. In our boarding schools the sex instinct often takes the road of auto-eroticism. In a co-education school the sex impulse is directed to one of the opposite sex. This attachment is nearly always a romantic ideal attachment. I have never known a case that went the length of kissing; among little children at a rural school, yes; at the age of seven I kissed my first sweetheart; but among adolescents I find that neither the boy nor the girl has the courage to kiss. Theirs is a sublimated courtship; they never use the word Love; they talk about "liking So-and-so." That at many co-education schools this romantic attachment is more or less an underground affair is due to the moral attitude of teachers. They pride themselves on the beautiful sexless attachments of their pupils; they give moral lectures on the subject of kissing, and naturally every pupil in school at once becomes painfully self-conscious on the subject. The truth is that many co-educationists do not in their hearts believe in the system; they still see sin in sex.
