and Amos...

"...phenomenological set of events which, while not material, are nevertheless actual, include individual insight, for example (not the brain waves, but the insight itself)

Can you guess that this reasoning gets, from me, a similar complaint?

"Not material, but still actual" is close to a paradigm example of what I am getting at. Calling 'insight'--the concept-- part of one class of 'actuality' is just Plato revisited, and not taken seriously in Philosophy these days....it is a linguistic class, and when restricted to this, is perfectly relevant to certain discussions.
Used as you suggest, it clouds....not clarifies... the attempt to discuss what can be studied & investigated by anything resembling 'scientific method'.

(I'm struggling to remember and construct the argument as my old professor, Gerald Paske, would say it.)
