I have always kind of pooh-poohed all that Armageddon Christian talk about demonic forces unleashed on earth…I don’t know so much anymore. Unfortunately that argument is becoming as reasonable an explanation of so many cultural phenomena as any other.
I agree that chimeras (even the human part) do not necessarily have human souls just because they have human cells. But I am concerned that this is a very ethically complicated area and meddling with some types of chimeras can undermine the dignity of the human person, reducing us to nothing more than machines and chemical reactions to be improved on or manipulated.
Science operates in a moral vacuum. That is the problem. Oppenheimer learned this the hard way, though there are many other offenders. And of course as a culture we worship science, not God. I question if science really sets any ethical barriers for itself.
I understand your fear, but this could lead to saving many many lives in need of organ transplants. Are we supposed to decry an experiment that is going to save lives because of what may become of this discovery? All knowledge can be used for good or evil. Is it not good to want to give people organs that they desperately need?
When scientific discoveries are made, regulations are put in place. I believe someone mentioned Oppenheimer? Well the nuclear weapon has been discovered and cannot be un-discovered, nor can the research done in this article be un-discovered. Regulations are put into place on nuclear weapons internationally to avoid mass destruction, since we can’t just forget how to build them.
There will be regulation, ethical regulation. Newfound knowledge is neutral, not evil, and it is being used for good in this case. Try to avoid immediately assuming that this is going to lead to a slippery unethical slope, and remember that lives are going to be saved with this.
