Full Idea

We cannot really be talking about the things whence an abstraction-like entity is abstracted if there are no such things.

A Reaction

Sounds like a killer blow, but I don't think so. I can't think of a concept which doesn't have a possible basis in reality, assuming that it might be a complex assemblage of abstracted components.
