Do you have evidence to show that people in the 1940's thought and felt differently from people today.
People in the 1940's still had the same evolved empathy, however empathy is strongest towards people who we have a close attachment with. Empathy for other family members is usually the strongest, followed by empathy for friends, & colleagues. Empathy for strangers is a lot weaker, which makes evolutionary sense. This does not mean that we have no empathy for strangers, however if there are situations where we have to choose between a family member or friend & a stranger, we will nearly always choose the person we have the most attachment to over the stranger.
Our empathy even for family members can however be weakend by strong charismatic persons who we develop an attachment to, or religious cults, or political doctrine. So it is not that difficult for a strong charismatic psycopath like hitler to turn an entire population against people like the jews, especially when the jews have already been demonised for centuries by many religious figures, & there is strong anti semitism running through the new testament.
The strongly religious, or those who are highly political will also often develop strong empathy for those of the same religion or side of politics as themselves, & disdain or even hatred for those who are not of the same religion or political persuasion, which can even include family members.
I would say it would be far easier to turn a country of mainly Christians (or Muslims if it had been an Islamic country), against a minority group of people like the Jews, than it would have been if the majority of the country were atheists, with no religious affiliation.
From an evolutionary point hitler was trying to improve humanity by removing what he consider unfit from the breeding stock. As an argument it is far more valid than saying the holocast was wrong because we have empathy.
What hitler was trying to do has nothing to do with evolution, & it also does not invalidate my argument for evolved empathy. Hitler was a psycopath. Psycopath's can find any excuse to hurt people, which often involves religious texts. Hitler was bought up as a roman catholic.
Slave owners in the American south used both the old & new testament to justify the keeping of slaves. Religious texts were also used to justify the forceful colonisation of countries & the slaughter & subjugation of the natives, by both christian & islamic colonisers.
Tell me how does empathy tell you that the abortion holocaust happening today is wrong.
Because of evolved empathy humans have developed hospitals & science.
Today thanks to science & our evolved empathy far more babies are saved from death than are ever aborted. We can now save premature babies that otherwise would have died, the incidence of still births & mothers dying during child birth has reduced dramatically. we can perform operations on babies to fix heart defects etc, that normally would have led to their death. Most children will now live to be adults, & live to old age, rather than dying from disease or infections before the age of 15, which was the norm in the past.
If we didnt have evolved empathy we would not have seen any reason to develop the methods to keep premature born babies alive, or for society to foot the bill for the enormous cost that this involves.
Regarding abortion, evolved empathy also means that we will usually have far more empathy for the mother than the unborn child, because we might know or can see the mother. We have never met the unborn child, so the empathy will be nowhere near as strong as empathy for the mother, who might have a good reason for aborting the child.
Most strongly religious persons who are against abortion have no empathy for either the mother or the unborn child. They are merely trying to push their religious agenda on the rest of society, & for political power. Their real motives usually have nothing at all to do with concern for the unborn child.
Its a shame that the bible gave no basic instructions about the importance of cleanliness to prevent the spread of germs & disease, which has been a major cause of death throughout history, which includes many babies, children & mothers. Infant mortality, & the death of the mother during or ater childbirth was extremely high till only about 150 years ago. One would think that a loving god who is concerned about infant mortality would have given some insight or commands to help prevent this from happening.
God also sanctions abortion in the bible. If a husband suspects his wife of being unfaithful, he can take her to the priest, which will mix up a concoction that she is forced to drink, that will cause her to have an abortion if she is pregnant. The stoning to death of adulterers is also sanctioned by God, some of who will no doubt be pregnant.
In fact there is really nothing from the biblical texts that would lead me to belive that abortion is wrong. Many unborn children would also have been slaughtered or left to die in the genocides commanded by god.
God ordered genocide.
Are you aware that no one has recieved such a command since the times of King David.
What does that have to do with anything? The precedent had already been set before then. God of the old testament not only ordered genocide, god also committed genocide, & genocide also continues today, often with religious texts used as the justification.
And if god is the creator of everything, then god has also continued genocide to this day.
IF we are to believe the creationist view that God is the creator of everything, & evolution is NOT the cause of all the different forms of life that we have today, then genocide is ongoing. If this is REALLY the case, the only conclusion one can come to about the cause of all the disease in the world, is because god is continually committing biological warfare against us.
God apparently created the perfect weapon to commit biological warfare, the mosquito, which carries & transmits diseases such as malaria, dengue fever, ross river fever to name just a few (god must have also created the diseases as well). In fact the mosquito is said to be the biggest killer of all of humanity. This is just ONE of the many biological weapons god has apparently created to kill us. And it is often the poorest of society who are the most affected by these diseases. Which leads one to the conclusion that god must hate poor people.
Parasites such as the mosquito, & the many other parasites that cause death, disease & suffering, only make any sense if evolution is the cause. If a god is the cause, then the god must be a psycopath, & not worthy of worship.
Morality if it is not an absolute then empathy has nothing to do with right or wrong but everything to do with what one feels is right.
Morality has evolved as our cultures & society has evolved. If morality is an absolute as defined in the bible, then some of us should still be slave owners, & some of us slaves. We should still be stoning people to death for transgressing certain laws that are defined in the bible such as adultery. There should be no freedom of religion, there should only be one worldwide religion that everybody is forced to follow.
Different cultures & societies have different moral beliefs that everybody in that culture is expected to adhere to. However if some people in the culture or society believe that a moral value is wrong, then they may be able to convince others that it should change. If enough people are convinced, then a new moral belief may be introduced to change the old moral belief. This is what has happened throughout history, & it is still happening today.
Thankfully through secularism, science & reason, morality is evolving in a direction that is fairer for ALL in society, because our morality is NOT constrained by outdated biblical principals. I would argue that there is quite some way to go, & that any changes could have happened a lot sooner if it was not for religious conservatives & vested interests fighting against the changes.
The biggest advances in human morality & animal welfare has been in secular countries. The countries where morality is lagging behind is in the non-secular countries, where religion still holds most of the power. In some countries, where religion still holds sway, adulterers, blasphemers & homosexuals are still stoned to death, & many other barbaric acts are still performed in the name of 'religious morality'.
The biggest threats to morality evolving for the better of all in secular countries, is for some religious nut job gaining power & wanting to take us back to a biblical version of morality, as ISIS tried to do wherever they gained a foothold.
Even in the bible, morality is not absolute. For instance in the 10 commandments, one of the commandments is 'though shalt not kill' yet the bible is littered with killings, often at the 'command of god'. The commandment 'though shalt not committ adultery' is excused by even fundamentalists, especially if the person committing the adultery is percieved as doing something to advance their cause, such as a politician expousing 'family values' or if they are against abortion, such as trump for instance.
This makes the bible useless as a moral guide, because I can find any no. of reasons for killing somebody from the biblical texts (& throughout the centuries christians & muslims have).
Many Christians also say that most of the laws in the old testament no longer apply to them, so again, more evidence that even the biblical version of morality has changed & evolved through time, so where is the absolutism!
