The sex-instinct is one of the most deeply-seated expressions of the will; and it must not be restricted, either negatively by preventing its free function, or positively by insisting on its false function.
What is more brutal than to stunt natural growth or to deform it?
What is more absurd than to seek to interpret this holy instinct as a gross animal act, to separate it from the spiritual enthusiasm without which it is so stupid as not even to be satisfactory to the persons concerned?
The sexual act is a sacrament of Will. To profane it is the great offence. All true expression of it is lawful; all suppression or distortion is contrary to the Law of Liberty. To use legal or financial constraint to compel either abstention or submission, is entirely horrible, unnatural and absurd.
