In the first place, the scientific knowledge that underlies cloning and the technological ability to clone are no more and no less morally charged than is our basic human nature itself. Cloning is neither unnatural or bizarre. Rather, it is in principle an unsurprising exemplification of what we have known for a long time about ourselves. A creature that can, through genetic engineering, totally rearrange the life-forms that constitute our agricultural enterprises could also, almost predictably, be expected to learn eventually how to make itself. In cloning, we are in fact addressing ourselves, and it is about ourselves that we have the greatest questions.
Cloned humans are real persons.
The life we engineer in the laboratory is really life. Inasmuch as the cloner of humans is itself a natural creature, cloning must be considered to be a process of nature. As such, cloning humans would finally be more like nature's process of creating identical twins than some Frankenstein horror story. Parenting and schooling would continue to be critical in the development of a personal identity, since no human being can survive by genes alone. Many persons will have difficulty accepting these ideas, primarily because they are so alienated from nature that they cannot understand their humanity within the parameters of nature as we as know it today.
