poyltrip - Sorry
I must have misread some of the "intent", my apologies.
I didn't want this to escalate into an argument (damn I hate flat text sometimes).
As to your counterpoint...a few questions:
1) Evolution has measurable/quantifiable effects on a population. I would assume that in this case you are saying that there would be some sort of biological/physiological pathway that would code for morality. Is this a correct assumption?
To my mind I don't really see a problem with that, except, if we take into account the fact that morality varies from one society to the next it would seem that again, all we have is the capacity for morality. The specific morality would need to be mapped onto or imprinted to those biological characteristics. This is like the language example I presented earlier. We all have the capacity for language, but the type of language we speak varies based on a number of factors.
When applied to morality, this means that there are a number of dynamic "moralities" from which humans can be imprinted based on their cultural upbringing. In a Western society, murder would be considered immoral. In a headhunting society, murder (in the context of the grief that drives headhunting) would be perfectly acceptable. The reason I choose such an extreme example is because I feel it illustrates the fact that morality is so open to interpretation that even if we do have physiological pathways that encourage positive community interactions (morals) it is impossible to say what is moral. In other words, due to the mutability of what is moral within the scope of societies there is no inherent morality.
2) Is society necessary to comment on what is human? I don't think so...the cases might be few, but "feral" humans have popped up before. Are they not human because they're not in a society?
I think it is important to remember and be aware of how much people can differ from one society to the next...the elasticity of babies' minds is a wonderful example of this. I think it is safe to say that there is a biological/physiological entity known as a "human being." This entity has the potential to be radically different based on the culture/society it is raised in. The entity has a myriad of capacities, but the actual traits presented (be it linguistic; type of langaugue/sub-dialect, temporal; comprehension of time/space, or moral; acceptable actions) are dependent on the circumstances the entity happens to be in. With regards to all three examples, cultures/societies tend to dictate the terms of these understandings. If a lone human grew up in the wilderness in isolation from humans, the specific manifestation of his/her capacities would most-likely be directly dependent on his/her experiences. I see no reason why this could not exclude social understandings/structures of morals. At the point where personal survival is paramount (and not understood to potentially be subjugated for "the good of others" ) morals don't factor in; this is the basis of my initial statement that nature is amoral.
If a wild human chooses not to kill another human he stumbles across, it wouldn't necessarily mean he's moral, it could just as easily mean there's no adaptive benefit or survival reason to kill him. Additionally, if he does kill him, it doesn't mean he's necessarily immoral, it could just as easily mean there is an adaptive benefit or survival reason to kill him. This, to my mind, is what we see amongst animals and is the reason for my understanding of nature as amoral. Decisions are made and carried out based on the impact on their survival of the individual animal. When we start to get into social groups, a certain amount of personal impact is alleviated...this is one of the benefits of being social animals. If you have a hard time with something, others can help out in a variety of ways. As such, survival is mitigated in part by the group and morals begin to make sense in order to allow for social cohesion.
HF - if you look at the three definitions, 2 of the three put it in the terms I presented (with their first definitions presenting ethics as systems of morals). As I said and you repeated…it is a nuance. There are plenty of terms presented as synonyms that are less than perfect as far as synonymy goes (just use the thesaurus feature on M$ word; there are numerous examples). Personally I think it is an important nuance, but clearly we differ on that. Such is life. The only reason I'm engaging in this is because I made a statement and was essentially asked to clarify. I've pretty much said the same thing as you with regards to the relevance or application of this conversation, which was the main thrust of my last post. This was also the reason why I made the comment regarding to the applicability of your earlier post to my statement.
As polytrip wants to continue the discussion in order to whittle away at some concepts, I see no issue with that. I'm sorry if you think me to be obtuse or to not have given your post an appropriate amount of time/thought. As I said, we clearly differ as to our thoughts on certain semantic distinctions. I'm not trying to argue or get your goat or create problems, I'm merely presenting things as I see them.
