Full Idea
The doctrine of Quine called "meaning holism" offered arguments refuting logical positivist attempts to show that every term we can understand can be defined using a limited group of "observation terms".
Gist of Idea
Meaning holism tried to show that you can't get fixed meanings built out of observation terms

A Reaction
