Thats what I think. Social discourse should always include learning.

I agree if its a argument as sometimes people just bang heads; but trying to understand where the other is coming from is quite a hard job if you are also trying to get your own points across. I think I often do get to learn something from a discussion - not keen on arguments. I like tossing options around with others rather than starting from a place of disagreement.

A noble thought, but who actually follows it?
“A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”
― Max Planck, Scientific Autobiography and Other Papers

Finally a Joubert quote l whole heartedly agree with. ☺

Absolutely the right way to approach it.

The whole point of an argument is to increase knowledge, to learn or to teach or a bit of both. If not then you might as well sit in the park and shout at pigeons!
