t I think that it is the nervous system (ability to experience pain/pleasure) that played a big part in the developement of morals. I think without it humans would have never started to think about right and wrong. I was just wondering why human brains have been able to start thinking about right and wrong and whether this has a physiological cause.
Mental constructs, thoughts, ideas about ethics, morals etc. On a biological level are a certain type of brain activity in certain areas of the brain with certain neurotransmitters firing. This particular chemical reaction in the cortex that leads to ideas or constructs such as morality and ethics is influenced by primitive feelings such as the feeling of pleasure and pain. So I think the origin of thoughts such as right, wrong, ethics, morals etc. lies in primitive brain structures that are responsible for our ability experience good and bad feelings. If the ability of those primitive nervous system structures to experience pain/pleasure was absent we wouldn't be alive and if we were than I think that we would not have developed concepts such as right/wrong etc. etc.
nope, sorry to harp on the same point over and over, but i think it is important to realize that morality is objective (it cannot change and your thoughts/opinions/biological functions have no effect on it whatsoever) whereas ethics are subjective (eg. it is never moral to lie, but it is ethical to lie if it benefits the person being told the lie. It is never moral to hurt someone, but it may have been ethical to kill Hitler before he had a chance to harm anyone)
i know it's only a minor semantic objection, and i basically agree with what you are saying, there is just a minor malfunction in my brain that refuses to conflate ethics and morality. (not a big fan of "morality" claims)
Now onto the evolution of ethics (morality cannot evolve), Not everyone is born with the same ethical principals, even today people do ignorant things to each other for no good reason, but humans are a pack species, and in modern society we remove unethical individuals (jail, death row, whatever) and this causes them less freedom to proliferate their "unethical" genes, so an "ethical" individual is much more likely to reproduce. Before society modernized it was a little more "gritty", but basically anything that broke down the "pack mentality" (humans are a pack species), caused that pack to die off, leaving only the packs that were capable of working together, and natural selection has been slowly removing the "non pack" humans for thousands of years, so it's not like What you think has any effect on your evolution, but if the way you think doesn't help you survive in a pack, you won't. (long winded way of saying i agree that the physical world selects the minds most fit for survival)
