Oh, this is totally different than the objection I thought you were making. So thanks for clarifying.

Okay, so:

"minds encode concepts in terms of necessary and sufficient conditions" and "minds can work with the framework of necessary and sufficient conditions" are two distinct factual claims about minds.

Agreed. Like I say:

It is useful in many cases to talk about concepts in terms of necessary and sufficient conditions. I use stipulative definitions like this all the time.

My argument is not against the entire practice of seeking definitions in terms of necessary and sufficient conditions. My argument is against the practice of doing so under the assumption that what we're getting at with such definitions are the concepts in our head, rather than more stipulatively defined concepts that, in many cases, may be more useful than our intuitive concepts anyway.

"It's the map and not the territory," right?

I may be way off base here, but isn't the root of this disagreement that lukeprog is saying that our mental map called "conceptual analysis" doesn't perfectly reflect the territory of the real world and should therefore not be the official model. While Morendil is saying, "but it's good enough in most cases to get through most practical situations." Which lukeprog agrees with.

Is that right?
