Many supporters of abortion think they have good arguments. They talk about the progress in medicine and technology: "new times" and changing circumstances demand that new measures by taken by responsible human beings. In the past the hygienic situation in the western world was similar to that in Asia and Africa today: many children are born, many die in the first year of their life, these are the limits of nature. "This is more primitive, but not more ethical" as Max Frisch says in his novel " Faber". Man more and more learns to rule over nature. If man is really man, he or she should be able to use his or her brain. The only question that remains is why it should not be possible to use contraception.
