I agree with this. What I don’t agree with is the notion that one can’t distinguish areas or proposals that aren’t science around the same time they are promoted. Not all cases, but certainly many. In other words, we can have very solid knowledge about whether a proposal is amenable to fruitful investigation or merely ‘word salad’.
I guess I could say that I’m not personally interested in policing what is and isn’t science, but I’m willing to enter discussions with others who propose that science cannot be distinguished.
