We have to think about this statement, because of what James intended by his word "better". If he thought it like pple without diseases and malign illnesses then i must agree, because it is new way how to help people just like any other modern methode of health service.On the other hand if it was thought like stronger,smarter and finer then i disagree, because i dont see any reasonable ground in doing that.
Lets try to keep our world as natural as we can.
