Most basic thing among people

I am still almost addicted with Faure's nocturne. This No 11 in f sharp minor is most poignant and moving one. It is titled by Faure as "à la mémoire de Noémi Lalo". Noemi is told to be his friend's wife.

I don't know why but always feel relieved as well as soothed at this piece. It is a typical elegy still providing us with calmness. 

I am only ingnorant of musicology and am not capable of analyzing compositions. But they say some of Faure's works are based on Gregorian mode which he has been trained at Ecole Niedermeyer in his young days. And, as I recently heard from a musicologist, certain old Japanese mode has something common with Gregorian. I got inspird that there had been some mode in music common all over the world. Music must be originally born imitating sounds of nature and putting our emotion to them. It could be brought birth at various places in the history but that progress may not be so different in the beginning everywhere. The idea of similarity of modes in music has lead me to such a fanciful thought.

If this idea is right, why are people still fighting or even killing each other in the world? They emphasize the difference of races or cultures as the reason. They insist owning certain land on the globe, which only a few previous generations of their ancestors have had. When we leave this earth, what does it mean to own some land or resource in the world? We should return to the most basic emotion we share as mankind.
