Cohens main claim is that arguers are better at losing and you learn from losing.
He says that arguing mostly comes out in a war like way. This war metaphor makes it seem like the other won and you lost, but really you gained from it because you were asking questions about their point of view and you learn their position in the argument even if you do not agree with it you still learn from what they are saying.
His idea that arguing is like war was new to me because I had never thought about it like that before even though it is very true.
My question is how do we learn from others when in an argument because most of the time people are so set with their opinion they do not take in anything what the other is saying.
A new idea that could be useful in writing this essay is to put yourself in the audience position to see how well your argument is and that it does well and uses strong evidence.
