"One problem, for instance, is in MSK's view of "biological nature". Certainly the requirements of the baby's life are explained there."
I wonder sometimes about how expressions are vague. Is it possible that my observation that human beings have a biological nature is my personal view (my opinion) and only my view? Is this observation true for some people and not true for others? Does anyone contest that human beings have a biological nature? Is this even debatable? I would be very interested in hearing an argument to the contrary.
Also, the requirements under discussion are not only those of the baby's life. All adults were once babies, so in essence, the requirements of the adult's life are contingent on the requirements of the baby's life. If the baby does not survive, there will be no adult. There is no such thing as a baby human being as one species and adult human being as another species. They are both the same species. For individual rights to be universal, one phase cannot be excluded. Any claim that it can be excluded is irrational, i.e., based on some standard other than reason. Such concept of rights is arbitrary by the very definition of man.
"But isn't the concept of rights also contingent on the fact that there is a harmony of interests possible?"
Harmony of interests for whom? Individual rational animals, or individual rational blobs without any other nature than "rational"? Objectivism is a philosophy for human beings, i.e., rational animals.
"If the world were truly zero sum, where one man's gain is another man's actual loss (your survival means the death of someone else), what happens to rights?"
Where did production enter this argument? Zero sum is a concept applicable to production, not biology. Survival and care of the young are biological issues.
How's this biological sum for sex, going to the other side of the equation?
1 Male human being + 1 Female human being = 3 human beings.
That sure ain't zero sum...
Why don't animals have rights, since they have requirements for living as well?
Obviously because they are not rational (the differentia in "rational animal"), do not have conceptual volition and thus cannot have a philosophy. I don't really understand this question. Are you presuming that rights can be conceived somehow outside of philosophy?
Steve P,
"Do human beings have a biological nature prior to birth? What are the moral implications?"
Of course human beings have a biological nature prior to birth. How is that debatable? What on earth is a human being without a biological nature?
On the moral implications, the real question is when does a fetus become more than a potential individual human being and actually become one. The obvious point is upon birth, outside the womb. Modern science is showing this to be a more or less a couple of months before birth, since the baby can be removed and still achieve birth at the time of removal.
As regards rights, they should exist starting with birth if we are to have a rational society based on freedom and individual rights. Borderline cases (very late-term abortions like at 8 months, for instance) should be treated on a case-by-case basis with focus on context and even science.
