I think it is rational. We come to the same conclusion using different methods. On my side the method rests upon the concept of “reciprocity”, which is formalized into the negative version of the “golden rule” – namely: “do NOT do onto others, what you would not want others do onto you”. And I am sure you realize that this is a fully secular concept.
It is fully secular. It is also fully axiomatic. The fact that you derive it from a stipulation does not make it rational, nor does it give you any basis other than assertion and general agreement.
Since the fetus is not an adult human, there needs to be a different principle involved in this question. Where a problem arises is that many theists with to establish an “ironclad”, no exception based, “absolute” ethical system, while unbelievers are satisfied with an objective, but not absolute system. Of course the believers immediately shoot themselves in the foot, when they stipulate that their “absolute” ethical system is not applicable to God – and thus they admit that their ethical system is not “absolute” at all.
The claim that “Since the fetus is not an adult human, there needs to be a different principle involve in this question” is not clear; right now it seems like special pleading although perhaps you can substantiate it. It is not like we have to make qualifications for any non-adult human. Your ethical system, presumably, applies to children, and we might also suppose, post-birth humans who are not fully rational (due to mental illness etc.). The prevailing view in America even applies to fetuses of some age. So clearly it is not just the fact that the fetus is not an adult human which justifies either overriding its rights or stipulating that it does not have rights.
So from what you have said here, I cannot find any particular reason for excluding fetuses of particular ages from your ethic of repricocity. To say that it is because they are not adults is arbitrary and inconsistent, which would mean that the ethical system is not objective, whether or not it is absolute.
I have not stipulated that my ethical system is not applicable to God, but God is not taken to be
a human (even if humans are made in His image and He became man), so as Peter Plato says, the burden would be on you to show that there are not relevant moral differences between humans and God. Such an argument would have to be part of a consistent theology, which I suspect you have no intention of providing. I’d add that natural law ethics construe morality as deriving from the fulfillment of a things ends, in which case we would be constrained to acknowledge that God has no formal moral obligations because He has no ends. Since this reason is non-arbitrary, it is in no wise special pleading. But this is irrelevant to the present discussion, which is about secular values and ethics, so we are debating whether it is possible to construct a coherent secular system of ethics; what theists believe is irrelevant.
Not exactly. We need to balance cooperation and competition in this “game of life”. And the game theory comes to the help in conflict resolution.
Since we are all biological beings, we have a common ground to negotiate such questions. Rational people understand that both fully selfish and fully unselfish behavior leads to incorrect solutions; therefore there is a need to balance these behaviors. Again, this is only a principle, and to “fill it with meat” one needs actual situations.
Selfishness and unselfishness lead to “incorrect” solutions? What makes a solution “incorrect,” as “rational people” apprehend it? Is correctness only informed by biology? What in particular would make cohesion with biological tendencies (say, characteristics derived from natural selection) the good of your ethical system (if they are - I cannot tell)? What makes biology an objective standard?
There are no “absolute” methods to resolve conflicts. It is very sad that after tens of thousands of years one of the “most prevalent methods” to resolve conflicts is the use of force. Our progress toward “civilized” behavior is abysmally slow, but it exists. There are some higher apes (the bonobos) “who” are much more “civilized” than humans. They actually live by the principle: “make love, not war”. When they are frustrated, they engage in gratuitous sex, and not fight. If only we, humans would grow up - ethically speaking – to their level. If only the church would realize that sex is a great therapeutic endeavor, and not some “sacred” activity. But that is too much to hope for.
It is
indeed very sad that after all this time, we resolve conflicts by force. Say, by injecting a fetus with a fatal solution or by snipping its spinal cord. One might even get the notion that modern progress is not just
slow but regressive, when we resolve the conflict between a mother and her unwanted child by killing the child.
As for sex, it is a good, but it is not an unqualified good, owing to the emotional ties that people make through sexual intercourse.
Monogamous sex partners report the highest satisfaction. It is not clear that we’d all be better off if we made like the great apes.
