I have implied in this book that the very best in sexual experience is only for those who keep themselves unspotted in early life, and who come to the sacrament of marriage with no previous and lower experience of sex intimacy. I am even sure that the very best is spoilt a little by all previous unworthy thinking, and by all perverse practices. I know that that will sound a hard saying to very many, for there are few who have fulfilled these conditions for knowing the best. It must seem to them that I am practically saying to them, "You can never now enter into the holy of holies." Yet I cannot alter what I have said, however acute may be my sympathy with those who have stumbled. I believe it is true, and no good ever came of hiding the truth. It is because it is true that I have such confident hope for mankind. Men and women do in their hearts want the very best, and when they come to know what are the only terms on which that very best can be had they will, I believe, accept those terms. But this would be a cruel book, and a false book too, were I to imply that there is no way in which the past can be forgotten and forgiven, and no way into purity and joy even for those who have wandered. Were that so I could not write at all about this subject, for it would then be too tragic. Perhaps the worst consequence of aberrations in thought and conduct is that they make it very very hard to be perfectly happy and unashamed when at last love calls them to enter into the inner chambers of marriage and romance. The shadows that rest at times on that part of marriage even for some very happy lovers are due to the fact that the man (or sometimes the woman) was once involved in something else before that was a little like it, and yet was haunted then by a sense of wrong-doing and so could not have a perfect experience. It is only to the pure that _all_ things are pure. But it is _not_ true that the past need dog and spoil the future. It is not true that sin is irremediable, nor that its stains remain for ever. The essential and central thing in Christianity is the assertion that there is a remedy for the situation that sin creates. I do not think there is any remedy to be found in simply trying to ignore the past--or in saying that our aberrations were only those of ninety per cent. of mankind, and were so natural as to be not worth bothering about. In such ways we may push the past out of sight, but we do not deal with it. It remains there though out of sight. For the fact is that such sayings do not quite convince us, and therefore they cannot kill the past.
