What morality can be logically derived from Evolution?

Could you explain a bit more what you mean by logical basis , do you mean use to establish moral absolutes ?
I can think of a number of behaviours that would promote long term survival ,that I would not want as a basis for a moral code. For example..
a)Maximising childbirth so as to flood the population with your hereditary traits , males and females would clearly strive to achieve this by different routes
b)Preventing the competition from breeding , we can get into some very unpleasant areas from here .
c)Having a social system of positive discrimination for your offspring.
Personally I do not see nature as a source of a moral framework , morality is a unnatural condition that we impose upon our selves and acts to modify our instinctive behaviour . It is a produce of our intelligence , and I think we can see that in many cases the uses that we put that intelligence to does not seem to promote the long term survival of our offspring.

Hello RAZD Do we? , I did ask if you looking for moral absolutes , are you?I think we must be careful not to mix morals and law , we generate a lot of social behaviour laws that aid the running of our social groupings , many based on practicality , but are they moral ?Example , it is a crime to steal from someone else , BUT what if the robber is starving and he steal bread from a very rich man ?Which comes back to my question about moral absolutes , now I know these have been debated in many threads , so rather that be specific , I am talking about them as a concept ,can you derive any absolutes from “behaviours that promote the long term survival of offspring “?I would take the position , that with out a set of absolutes to use as a foundation , the moral code is fatally flawed , as it will be dogged by grey areas .From our previous posts I think we can agree that what seem like advantageous “behaviours that promote the long term survival of offspring “ are not as clear cut as would first seem , and give that our intelligence has shifted the survival pressures that are upon us , can we target those important behaviours at all?Your replies to my few example in my earlier post , make my point , that to promote one offspring seem to come at a price the rest of humanity would have to pay .
Simple taking those three examples , one could envision a culture of a breeding elite , with a underclass off sterile servants and workers , who’s sole purpose is to care for the elites offspring and maintain the infrastructure of the society . now where on earth would one find such a system ..?

Yes I was meaning the social insect model , but in a very generalized way . Taking it as a given that we are social creatures and our “behaviours that promote the long term survival of offspring “ has to function with in a social structure , we can look at a the generalized insect model as an extreme example . I was careful to avoid the use of the word slave as that would imply the use of force to maintain the social structure and would not be a stable system .
If the moral system a society uses is based upon preferential promotion of a certain genetic line , within the population , i can not see how such a system would not drift towards a extreme form, in what ever shape or model you choose to consider.

Do you agree then , taking your above statement as a basis for identifying moral behaviour ,it would be apparent that some parts of the population would have a strong predisposition for immoral behaviour , and thus your logically derived moral code is discriminatory ? I would totally agree with you here , which is why I believe it is important to try to distinguish between social laws , and social morals . Returning to our Hugo-esque scenario the bread robber is unlawful, while the rich man may be considered immoral for not helping others .To consider your golden rule of “do unto others” is not the rich man not in breach of that rule .Social groups , tribal or otherwise , to me , always seem to go against your golden rule and become “do unto outsiders what ever you like , do unto insiders what ever you can get away with ,while making sure you promote yourself within the group “.Xenophobic trends and personal greed seem to be some of the most universal human behavioural traits, leading to .
Me before you
My family/houshold before your family
My neighbourhood before yours
My town , my district , my nation, my geo-political /my planet . ..Are these “behaviours that promote the long term survival of offspring “ one could make a case that they are , I am not sure , what do you think ?In the modern information rich social / tribal context we live in laws, and the penalties they impose when broken, seems to have become more important that morals . When one hears of a moral outcry , and I do not mean in the sense the Media tends to use the phrase , it is in the context of a religious view , or a harkening back to bygone eras ,not some current ,globally relevant ,code. Personally I believe this is , in part , due to the fact that those moral codes have been found wanting , with to many grey areas , and claims of” because” , rather that being able to hold up a absolute reason why some thing is moral or not .Socialites need its members to conform to the agreed social format , the question seem to be , does the format need to be moral , for it to be a successful social unit .
