We can just wing it, if we don’t care about things like absolute truth or sticking to something logical.
There are many works that find new ideas or are really thorough, combing through the breadth of human experience.
It is useful for people to spend their lives analysing these concepts and ideas. Their discourse can then be synthesized into new thoughts that will shape our societies. Do you think the laws you live by, the governmental structures, the way people treat each other, the structures of our societies would be like this without the studies of the humanities?
I mean, I'm suspicious of individuals who can't hack it in general, too, but not sure how that's relevant.
I’m skeptical of the latter, not the former, if that helps clarify my position.
