Riemann:
You seemed to be under the misconception that if our thinking is in any way conditioned by nurture (cultural transmission), then it is not instinctual. But this is not an either/or question. Our brains evolved, just as squirrel brains evolved, and they are not blank slates.
Cultural transmission is far more important for humans than for other animals - that’s how we dominate the world. But clearly we evolved from animals that operate instinctually. And it makes little sense to suppose that evolution would somehow have wiped all design from our brains, to turn just human brains into blank slates, into hardware without any software or operating system.
With language, for example, it’s an open question just what our genetic (instinctual) endowment consists of. But nobody seriously questions that there are both genetic (instinctual) and environmental (cultural) contributions to language acquisition.
Please don’t imagine that I think we are not slaves to instinct. We have already killed this planet, the only one we have, and we didn’t do it because we were smart.
