While it is right to stress the dangers of the permissive society, the argument from danger is not in itself a good argument, because it seems to imply that, if the danger could be removed, if there was no risk of a child and no peril of infection, then the objection would be removed, too. It tends to imply that the objection is to the attendant dangers and not to the thing itself. But if sexual intercourse before and outside marriage is against the teaching of Jesus, then the thing is not only dangerous, it is wrong in itself.
