To me it seems sad that there are some differences between Hegel and the Kant-Friesian school of Leonard Nelson. I can see how each complements the other. But the differences that started between Hegel and Fries have just kept on going. It is not that I see peace in itself as a goal. Rav Nahman said there are two kinds of debate one is between tzadikim and other is when a tzadik is making effort to be rid of the Sitra Achra and the wicked.
He brings this in LeM  I:5 and that and also at the end of LeM vol I about King David. [There the issue was the Saul was persecuting David, even though Saul was in fact a greater tzadik than David. See the Gemara that Saul was asking God "You said You would give my kingdom to my friend who is better than me. Now you say you are giving it to David. God answer when you were in the Physical world, (a world of lies), I told you a lie. Now I am telling you I am giving the kingdom to David." So we see in the Gemara itself that Saul was greater. And this is clear in the later prophets where there is counted 7 shepherds and 8 princes that would protect Israel if they were around. And there Saul is counted not King David. 

[The idea of "arguments between tzadikim (the righteous)" is one very useful bit of information in Rav Nahman. It sort of hints to the idea of Kant of the "dinge an sich" areas where Reason can not enter.]]
