Now as I told EAllusion: what is important to personhood? Why is infanticide wrong? What is the difference between late term abortion and infanticide? Please answer my questions so I can better understand where you are coming from.
I understand you prefer the answers to such question be derived from what scientific investigation has to say about what Is, and that ethics or moral philosophy's many approaches with varied results telling us conflicting things about what Ought to Be is unsatisfying. So, with that in mind, I decided I'll take the approach of answering you as best as I can relying on what the scientific method tells us Is. The results aren't my personal view of what Ought to Be, but we work with what we are given I guess.
First, based on observations of nature plant life is able to sustain itself by converting solar radiation into a form of energy that can be used to support cell activity. Animal life, however, must rely on the taking of life to sustain life. This includes the taking of plant as well as other animal life. Animals taking life Is part of the natural order of things, then.
We also observe in nature that killing includes risk as other animals have instincts they've evolved to protect their own lives such that they defend themselves in ways that strongly discourage attempts to take their lives. This includes fighting and potentially killing their attackers in defense. We observe that part of the natural order of things is predators minimizing risks to themselves as they hunt which includes seeking out the weak, old and very young. Animals killing other animals who are weak, old or very young Is part of the natural order of things.
Observations of nature have given rise to the theory of evolution which is strongly supported by evidence. It tells us that the success of life on our planet has been the result of intense competition where the genetic traits passed down through generations intersect with external environmental conditions such that those best suited to their environments will also be more successful in passing on their genes to future generations. All life currently present on the planet is the result of these evolutionary processes. Because of this, we understand we Homo sapiens have also evolved as animals. And as noted above, this tells us that for Homo sapiens, taking life Is part of the natural order of things.
We also have evolved strong biological drives that are the result of these pressures which compel us to seek the success of our own genes followed by those of our immediate family members whose genes are most closely matched to our own. On the other hand, we have impulses that cause us to fear or even hate those least like us, and these impulses are the result of our past ancestors successfully navigating their environments to be able to pass on the genes we have inherited. This stragegy of protecting our own genes while seeking an advantage over other Homo sapiens so our genes are the ones that proliferate just Is part of the natural order of things as well.
Based on this, it seems your premise that infanticide is wrong is flawed. It seems the premise more closely aligned with what science has to tell us about what Is would be the killing of infants for consumption who are not closely related to a person Is logically a reasonable way to acquire the needed energy and other material required to sustain one's own cell activity. Thus, it seems science is telling us that killing and eating babies is not something we should call "wrong" but would be recognizable within the natural order of things.
Can't say I agree with that conclusion but again, it's just an observation of what Is and then infering some form of purely science-based code of conduct from it. Otherwise one would end up trying to determine what Ought to Be, and that isn't what science does.
