You were given two links earlier in the thread which would give you more than enough information about the subject matter. Whether you take the time to read them is up to you. But it’s somewhat disingenuous to claim that you haven’t been supplied with evidence.
That is not supporting your story (or some parts of it) with evidence. That’s just pointing to a list of mostly irrelevant propositions of dubious certainty (it’s Psychology, after all - protoscience, if not pseudoscience) and hoping some of them will fit.
And they do not seem to.
For example, let’s look at the very first of your claims:
People are born either generous or mean spirited or anywhere in between.
And the strongest claim of such kind in the link (which, by the way, was not provided by you) seems to be “morality has a genetic component”. That is not anywhere close to your claim.
Not to mention that your fairy tales are self-contradicting. For example:
Yes, the more ‘civilised’ portion of our brains have evolved to enable us to form…civilisations.That’s pretty obvious or we wouldn’t be here. Forming groups enabled us to better survive. But that portion of the brain hasn’t replaced the reptillian portion. That’s still there
Now, of course, one self-contradiction is on the surface: if the evolutionary advantage of acting morally is quite as great, as you made it sound, how comes that this pesky “reptilian portion” hasn’t been “fixed”? After all, it is not as if genes responsible for it can’t have mutations any more.
But it is even more interesting to compare this with your views concerning morality itself.
If it is the “reptilian portion” that is responsible for evil, and it is the “civilised portion” that is responsible for good, how should moral decisions look like? “Reptilian portion” is supposed to be mostly responsible for reflexes, instincts and the like, while “civilised portion” is supposed to be responsible for reasoning. In such case morally good decisions would be a result of reasoning, while morally evil decisions would be a result of impulsive, instinctive behaviour.
Now, does your view fit that? Let’s see:
Now all this happened in an instant. There is very often no time to think ‘What would Jesus want me to do’. You act (and here’s the word again) instinctively.
What we do, instinctively, is what we describe as being good.
And note the word ‘instinctively’ (as you said).
If a child is in need, do you really, honestly, truthfully think that an atheist runs a quick benefit/reward analysis to determine if she is going to help?
Nope. As we can see, you keep praising instinct, emotion, reflex, while belittling reason.
You do not really take your own position seriously.
Of course, given your praise for instinct and emotion and lack of respect for reason, it is not very surprising that it is so easy to find ways in which your position is self-contradicting.
