If my position was that some instincts are good and some bad? What? What do you mean by ‘If’? Isn’t it obvious?
Well, to be precise, your position seems to be both that all instincts are good and that some are good and some are bad, depending on what is more useful at the moment.
When you want to condemn following religious rules as “not instinctive” and praise actions of atheists as “instinctive” (or when you almost define “good” as “what we evolved to do”), you take a position that all instincts are good, but reasoning (used when one tries to follow rules explicitly) is evil.
When this position is challenged, it becomes obvious that defending it is too hard and unpleasant: it is too obviously false. Then you move to position that some instincts are good and some are bad. After all, it is easier to defend. But, of course, when you take it, you can no longer do what you want.
This technique is called “Motte and bailey doctrines” (term introduced in paper
https://philpapers.org/archive/SHATVO-2).
Now what do you think would be more beneficial to the group and which would be more beneficial to the individual? A tendency to help the group even though you lose out in the short term, or a tendency to get whatever you could to the detriment of the group but which would benefit you only in the short term.
Again, the answer is blazingly obvious. But I’d just like to know you’re following.
So, here we are going to have “Motte” claiming that both good and bad instincts can give evolutionary advantage in specific circumstances. That sometimes genes are going to make acting morally easier, and sometimes harder.
Easy to defend, but useless in supporting your sneering at the believers.
And then there is “Bailey” claiming that evolutionary advantage of good instincts is great, that genes determine the character almost completely etc.
Want to show those are not “Motte and bailey doctrines”? That’s easy: explicitly condemn the opinions that “Bailey” supports.
As soon as you include the “cost” to obtain the “positive outcome”, you are a relativist and a utilitarian. As for referring to SEP, those articles are not necessarily “precise”.
So, we have a battle of authorities: professional philosophers that wrote that encyclopedia citing several sources against a random annonymous Internet user who cites no sources…
I wonder who will win…
