Your points are so misunderstood that I have no other choice than to start at the very beginning.
I think you definitely need to start over if you think I am mistaken.
This is how evolution and natural selection works for a social species like us:
1. We help others.
2. Others help us.
3. Helping others increase our general chances of survival.
4. Since helping others increases our chances of survival helping others is selected for by evolution and natural selection. Even if some should die in the process of helping.
Are you with me so far?
Evolution does not contain a single moral property or foundation. It is primarily the mutation of genes which result in genetic change. Natural selection merely selects which changes have survival advantage and will be preserved. And it is merely a theory, One which I will grant but it is not a process which has a single moral component. Why are you so obedient to a process that does not care about anything and would just as soon care if humanity ended today as continued? It is just plain weird.
Anything ethical you derive from this is an opinion and a guess. It an assumption piled on an assumption and judging by what you come away with it is a completely unjustifiable assumption. The issue is whether what you have derived from nature is justifiable. Does it actually reflect nature? So lets see.
1. We help others. Instead of looking at a theory that supposedly represents reality and guessing at what it demonstrates. Lets look at reality and see what it actually is composed of. I agree it includes us helping each other but it also includes us doing every conceivable harm to each other. Why are you suggesting good things are evolutionarily valid but the mountains of horrific things are inconstant with nature which is described and is red in tooth and claw. If nature is it then nature has justified slavery, war, genocide, etc... because it includes these things. Only with God are these things a violating of a transcendent standard which should be followed. As every single scientists you can find and they will respond that natural law nor nature as a whole can possibly ever tell us how things should be, only how they are. So whatever is, is what evolution justifies without God and you (if your honest) will have to take the good and bad. You can't white wash a thing and cherry pick from it and claim your still dealing with reality
2. Yes others help us in nature and others hurt us in nature. Using only part of reality but claim your using reality as is, is false. See the above.
3. This is so disingenuous. Yes at times helping others benefits us, so does hurting others. That is what nature is full of. Completely contradictory events.
4. This is merely a restatement of the previous mistake.
Nature is full of contradictions. History is full of contradictions. It is full of actions that we may like to think are benevolent and it is full of actions we may like to think of malevolent. However if we are to base how we act (and since without God there is no way to know which ones are which) we must accept it al or do what we actually do and completely ignore nature when establishing moral codes.
I do not know why, but it just hit me how weird it would be to think a cold immoral natural process is a basis for merely ethics alone. It does not care what is right, it does not contain what is right, it does not care about you, it justifies the gains of one creature at the expense of another, justifies eradicating those who are weak enough to weaken society as a whole. It contains the best of stuff and the worst of stuff and lacks any objective means in determining which is which. I can kill and be justified by evolution as Hitler did, I can save and be justified by evolution. And evolution lacks any means what so ever to tell anyone which one is actually the good. It does not care if you or anyone live, it would be just as content if every species on earth was wiped out and in fact it is responsible for wiping countless entire species out. It is among the worst possible foundations for ethics and can't possibly be a foundation for objective moral truth and no society has used it that way, thank God.
No I am not with you so far , because you are not with reality so far. Your putting a white mask on a black face and telling me that is the real face.
Artie I cannot make it any clearer than this. Your simply making massive mistakes here.
