Dean Inge believes Birth Control is an essential part of Eugenics, and an essential part of Christian morality. On this point he asserts: "We do wish to remind our orthodox and conservative friends that the Sermon on the Mount contains some admirably clear and unmistakable eugenic precepts. `Do men gather grapes of thorns, or figs of thistles? A corrupt tree cannot bring forth good fruit, neither can a good tree bring forth evil fruit. Every tree which bringeth not forth good fruit is hewn down, and cast into the fire.' We wish to apply these words not only to the actions of individuals, which spring from their characters, but to the character of individuals, which spring from their inherited qualities. This extension of the scope of the maxim seems to me quite legitimate. Men do not gather grapes of thorns. As our proverb says, you cannot make a silk purse out of a sow's ear. If we believe this, and do not act upon it by trying to move public opinion towards giving social reform, education and religion a better material to work upon, we are sinning against the light, and not doing our best to bring in the Kingdom of God upon earth." As long as sexual activity is regarded in a dualistic and contradictory light,--in which it is revealed either as the instrument by which men and women "cooperate with the Creator" to bring children into the world, on the one hand; and on the other, as the sinful instrument of self-gratification, lust and sensuality, there is bound to be an endless conflict in human conduct, producing ever increasing misery, pain and injustice. In crystallizing and codifying this contradiction, the Church not only solidified its own power over men but reduced women to the most abject and prostrate slavery. It was essentially a morality that would not "work." The sex instinct in the human race is too strong to be bound by the dictates of any church. The church's failure, its century after century of failure, is now evident on every side: for, having convinced men and women that only in its baldly propagative phase is sexual expression legitimate, the teachings of the Church have driven sex under-ground, into secret channels, strengthened the conspiracy of silence, concentrated men's thoughts upon the "lusts of the body," have sown, cultivated and reaped a crop of bodily and mental diseases, and developed a society congenitally and almost hopelessly unbalanced. How is any progress to be made, how is any human expression or education possible when women and men are taught to combat and resist their natural impulses and to despise their bodily functions?
