Although burdened by a sense of humor, Frankfurts On Bullshit has been a seminal work. I don’t know of any other equivalent study of bullshit as distinct from lying. The irony of ending up with pathological liar and bullshitter as the president made it clear that the distinction, while real, is very hard to identify on a case-by-case basis.
I just read another article today wrestling with a Trump set of statements as either lies or bullshit. As often with human questions, the quest foundered on our perspective external to Trump’s mind. The conclusion was that both are involved. There is a certain horror at attempting to get any closer to the source.
It’s ok, I don’t work as a philosopher although I’ve been accused of that. My point was not to usurp philosophical territory but to promote its increasing relevance in the paradigmatic collapse that we are in.
Professional rigor is critical to developed expertise. An unstated factor in what I was saying is that rigor is not limited to the academic practitioners. I think we need more people thinking philosophically as that, in my experience, creates its own demand for more data and greater rigor simply to answer our questions.
