Forel has in this connection compared the use of contraceptives to the use of eye-glasses.

Eye-glasses are equally un-aesthetic, yet they are devices, based on Nature, wherewith to supplement the deficiencies of Nature.

However in themselves un-aesthetic, for those who need them they make the aesthetic possible.

Eye-glasses and contraceptives alike are a portal to the spiritual world for many who, without them, would find that world largely a closed book.
Birth-control is effecting, and promising to effect, many functions in our social life.

By furnishing the means to limit the size of families, which would otherwise be excessive, it confers the greatest benefit on the family and especially on the mother.
