Being narrow with your own conceptual framework is good, but I'm promoting being liberal when it comes to interpreting others' concepts, when playing fast and loose in back-and-forth discourse, and when reasoning very abstractly in order to see connections. As long as you make sure to go back and make sure that everything connects precisely, and avoid affective death spirals around seemingly big insights about the fundamental nature of all things (which is somewhat difficult), it can be useful for getting new perspectives and for communicating concepts effectively.

ETA: With regards to communication, this only really works if each of the participants has some amount of faith in the epistemology of their conversation partner. If some random guy told me God exists, and I wanted to make him smarter, I wouldn't go on about all the ways that God exists; I'd go on about the ways He doesn't.
