It's not very helpful to study the ideas that form in human brains, though, since so many of them are nonsense. It would largely be a study of misconceptions and biases.

I think you could just as well have said "I believe our ideas are often formed on paper, when we write therm down. And that writing is part of the physical world. So I think the schism you presented would be void."

It would well be notable which ideas are wrong, no?

Sure I could've said, writing is physical. I just did, in another comment.
