Thực tế là kế hoạch nhà nước cộng sản là thảm họa không hỗ trợ đầu đối diện, kinh tế thị trường tinh khiết miễn phí. Cũng không thực tế rằng kinh tế thị trường tự do tuân theo mô hình toán học nghiêm ngặt, cho rằng các mô hình chịu rất ít giống với thực tế. | Myths of the Free Market viii Therefore abortion is always wrong independent of circumstances. This argument is widely accepted as logically valid. If the premises i ii iv vi vii are true then the conclusion must be true. The debate has focused on the truth of the second premise. Is or at what point is the fetus a human being a person morally entitled to be treated on the basis of his own interests At one end of the spectrum it has been argued that the egg is a person as soon as it is fertilized. At the other end it has been claimed that whatever it is it is not human until it leaves for medical school. Contrary to claims of the religious right it is not at all obvious that the zygote the fertilized egg is a person. The zygote does not have a brain. It never did. It does not have a heart. It never did. It is not sentient. It never was. Even under a microscope we would not recognize it as human. It is so different from anything we have ever regarded as a person that it is surely reasonable to question whether it is a person with moral rights. This is not to deny the close relationship between a zygote and a person. Biology texts routinely tell us that under favorable conditions the zygote will develop into a person. But this in itself implies the zygote is not yet a person. A child not yet an adult develops into an adult. A bunch of raw recruits not yet a well-trained military force develops into a military force. The caterpillar not yet a butterfly develops into a butterfly. A fertile egg not yet a chicken develops into a chicken. If the zygote is not yet a person but the just-born baby is at what point does the fetus become a person Science does not answer this question. The development of the fetus is a continuum from the fertilization of the egg to birth. This continuum is punctuated by discrete changes the first electrical discharge from the brain the first heartbeat quickening. No one of these events is so much more important than the others that it defines .
