Can Science Be Ethical ?

Freeman Dyson's  " Can Science Be Ethical?"  directly relates to "Brave New World". While Dyson  describes the future technology that will exist, BNW is the example society it will exist in. Dyson states that as scientific advancements are made our moral ethics will wane. In BNW  the dystopia is so technically advanced that humans are born through test tubes. One might ask, what happened to natural reproduction? Is it ethical, or morally acceptable to create a human? Is it acceptable to deny a woman her right at mother hood? In fact, in BNW, it is considered an insult to say someone is a mother. Dyson also foretells of people improving themselves and their children. Genetically modifying themselves in order to achieve perfection. BNW has genetically modified characters, who are chosen from birth to become whoever the society decides, no matter what the cost is physically and mentally it is to the person. As science increases it gains a more tighter grip on lives. Like a prophet of doom Dyson fortells a highly probable future with the way science is progressing. BNW seems to serve as a prototype or give us a clear example of the future. If ethics cannot be defined or a line is drawn people will loose the rights of a free thinking human being.
