Related to this are the scientific studies about the brain to show that human brains to not store definitions of words in terms of property-sets, boundaries, and the other tools of formal logic. The human brain stores
prototypes, i.e., an image of some canonical thing, and labels things based on resemblance to the prototype, such resemblance being necessarily vague. --

This was by no means settled: there are various theories about how human concept use and formation, of course. This article contains some useful information, but it absolutely is not an encyclopedia article at present. I'd like to go to work on this when I get a chance... --

I think the
empirical question
is well settled among working scientists. There is resistance among theoreticians and philosophers, but the experiments are quite clear and you really have to strain to interpret them any other way. Cognitive science has made quite a bit of progress in determining how the human brain works. That isn't to say that such results imply anything about the metaphysical nature of the world--or even the abstract concepts of thought, reason, cognition, etc. But physical human brains do work in very specific ways, and many of those ways have been clearly demonstated and measured. --
